Note:: âOrigin Server Base URLâ uniqueness: In order to enable MID caches to distinguish delivery services by different MSO algorithms while performing parent failover, it requires that âOrigin Server Base URLâ (OFQDN) for each MSO enabled delivery service is unique unless the exceptions listed afterwards. This means that the OFQDN of a MSO enabled delivery service should be different with the OFQDNs of any other delivery service, regardless of whether they are MSO enabled or not. The exceptions are: - 1) If there are multiple CDNs created on the same Traffic Ops, delivery services across different CDNs may have the same OFQDN configured. - 2) If several delivery services in the same CDN have the same MSO algorithm configured, they may share the same OFQDN. - 3) If delivery services are assigned with different MID cache groups respectively, they can share the same OFQDN. - -6) Select an option from the "Multi Site Origin Algorithm" drop-down list. Four MSO algorithms are supported: - -+------------------+--------------------------------------------------------------------------------------------------------------------+ -| Option | Description | -+==================+====================================================================================================================+ -| Consistent hash | Origin server selection is based on the consistent hash of requested URLs. | -+------------------+--------------------------------------------------------------------------------------------------------------------+ -| Primary/back | Round robin selection does not occur. The first origin server is selected unless it fails. | -| | If the first fails, the second and other following origin servers will be tried by order. | -| | Order is defined by 2 factors - if the origin server's cachegroup is configured as the | -| | parent cachegroup for the mid, then this server will be used as the primary. The same rules | -| | apply for secondary parents, in order. Within the cachegroups, the rank parameter will sort | -| | order further. If no parents are defined at the mid, then only rank is considered. | -+------------------+--------------------------------------------------------------------------------------------------------------------+ -| Strict | MID caches serve requests strictly in turn. For example: origin server 1 serves the first request, | -| round-robin | origin server 2 serves the second request, and so on. | -+------------------+--------------------------------------------------------------------------------------------------------------------+ -| IP based | MID cache goes through the origin server list in a round robin-based on the IP address of EDGE cache. | -| round-robin | | -+------------------+--------------------------------------------------------------------------------------------------------------------+ - -7) Optionally, there are two configuration options that can set the order of the origins used if "Primary/backup" is selected for "Multi Site Origin Algorithm". By creating location-based cachegroups and assigning the origin servers accordingly and defining these cachegroups as parents for specific mids, location-based primary/secondary selection can be made. If primary/secondary selection should be the same for all mids, then a new parameter ârankâ should be configured for each origin server profile. Origin servers with lower values of rank have higher ranking in the origin server list on MID caches, e.g. OS with rank of "2" precedes OS with the rank of "5". For any OS, if rank value is not defined in its profile, its rank value will default to â1â. In the event that both location based cachegroups are used alongside rank, sorting will be by cachegroup first and rank second. In this way it is possible to have specific backup servers for use at specific locations. - -.. image:: mso-rank.png - :scale: 60% - :align: center - -8) Assign the parent.config location parameter to the MID profile: - -.. image:: D22DCAA3-18CC-48F4-965B-5312993F9820.png - :scale: 100% - :align: center - - -9) Configure the mid hdr_rewrite on the delivery service, example: :: - - cond %{REMAP_PSEUDO_HOOK} __RETURN__ set-config proxy.config.http.parent_origin.dead_server_retry_enabled 1 __RETURN__ set-config proxy.config.http.parent_origin.simple_retry_enabled 1 __RETURN__ set-config proxy.config.http.parent_origin.simple_retry_response_codes "400,404,412" __RETURN__ set-config proxy.config.http.parent_origin.dead_server_retry_response_codes "502,503" __RETURN__ set-config proxy.config.http.connect_attempts_timeout 2 __RETURN__ set-config proxy.config.http.connect_attempts_max_retries 2 __RETURN__ set-config proxy.config.http.connect_attempts_max_retries_dead_server 1 __RETURN__ set-config proxy.config.http.transaction_active_timeout_in 5 [L] __RETURN__ - -10) Turn on parent_proxy_routing in the MID profile. http://git-wip-us.apache.org/repos/asf/incubator-trafficcontrol-website/blob/9694fb23/docs/latest/_sources/admin/quick_howto/regionalgeo.rst.txt ---------------------------------------------------------------------- diff --git a/docs/latest/_sources/admin/quick_howto/regionalgeo.rst.txt b/docs/latest/_sources/admin/quick_howto/regionalgeo.rst.txt deleted file mode 100644 index a903c8a..0000000 --- a/docs/latest/_sources/admin/quick_howto/regionalgeo.rst.txt +++ /dev/null @@ -1,109 +0,0 @@ -.. -.. -..

Note:: RGB is only supported for HTTP delivery services. - -1) Prepare RGB configuration file - -RGB uses a configuration file in JSON format to define regional geo-blocking rules for delivery services. The file needs to be put on an HTTP server accessible to Traffic Router. An example of the JSON is as follows:: - - { - "deliveryServices": - [ - { - "deliveryServiceId": "hls-live", - "urlRegex": ".*live4\\.m3u8", - "geoLocation": {"includePostalCode":["N0H", "L9V", "L9W"]}, - "redirectUrl": "http://third-party.com/blacked_out.html" - }, - { - "deliveryServiceId": "hls-live", - "urlRegex": ".*live5\\.m3u8", - "ipWhiteList": [185.68.71.9/22","142.232.0.79/24"], - "geoLocation": {"excludePostalCode":["N0H", "L9V"]}, - "redirectUrl": "/live5_low_bitrate.m3u8" - } - ] - } - -* The value of "deliveryServiceId" shall be equal to the âXML IDâ field of the intended delivery service defined on Traffic Ops. - -* âurlRegexâ is to match request URLs. The URLs matching the regex are applicable to the rule. - -* âgeoLocationâ currently supports âincludePostalCodeâ and âexcludePostalCodeâ attribute. When âincludePostalCodeâ attribute is used, only the clients whose FSAs are in the âincludePostalCodeâ list are able to view the content represented by âurlRegexâ. When âexcludePostalCodeâ is used, any client whose FSA are not in the âexcludePostalCodeâ list are allowed to view the content. âincludePostalCodeâ and âexcludePostalCodeâ are mutually exclusive in one rule. (FSA: Forward Sortation Area, first three postal characters of Canadian postal codes) - -* âredirectUrlâ is the URL that will be responded to the blocked clients. Without a domain name in the URL, the URL will still be served in the same delivery service. Thus Traffic Router will redirect the client to a chosen cache server assigned to the delivery service. If the URL includes a domain name, Traffic Router simply redirects the client to the defined URL. In the later case, the redirect URL must not match the âurlRegexâ part to avoid HTTP 302 loop on Traffic Router. - -* âipWhiteListâ is an optional element. It includes a list of CIDR (Classless Inter-Domain Routing) blocks indicating the IPv4 subnets that are allowed by the rule. If this list exists and the value is not empty, client IP will be matched against the CIDR list, and if there is any match, the request will be allowed and no postal code matching logic is needed. If there is no match in the white list, postal code matching logic will be processed further. - - -2) Add RGB parameters on Traffic Ops - -The two new parameters in following table are required to be added into CRConfig.json: - -* "regional_geoblocking.polling.url": the HTTP URL of RGB configuration file. Traffic Router will fetch the file from this URL. -* "regional_geoblocking.polling.interval": the interval that Traffic Router polls the RGB configuration file. - -.. image:: regionalgeo01.png - :scale: 100% - :align: center - -3) Enable RGB for a delivery service - -.. image:: regionalgeo02.png - :scale: 100% - :align: center - -4) Make configuration effective - -Go to Tools->Snapshot CRConfig, perform âDiff CRConfigâ and click "Write CRConfig". - -.. image:: regionalgeo03.png - :scale: 70% - :align: center - -5) Traffic Router access log with RGB - -RGB extends the field of "rtype" and adds a new field "rgb" in Traffic Router access.log to help to monitor the working of this feature. - -For "rtype", RGALT indicates that a request is redirected to an alternate URL by RGB; RGDENY indicates that a request is denied by RGB because there is no matching rule in JSON for this request. - -For "rgb", when RGB is enabled, it will be non-empty with following format:: - - {FSA}:{allowed/disallowed}:{include/exclude postal}:{fallback config/current config}:{allowed by whitelist/otherwise} - - -* {FSA}: It is the clientâs FSA part of its postal code, which is retrieved from geo-location database. If FSA is empty, dash (â-â) is filled in. -* {allowed/disallowed}: This flag shows if a request is allowed or disallowed by RGB (1 for yes, and 0 for no). -* {include/exclude postal}: It shows that when a rule in JSON is matched for a request, it is an include or exclude list of postal codes (i.e. FSAs). âIâ for include, and âXâ for exclude. If no rule matches, dash (â-â) is filled in. -* {fallback config/current config}: when TR fails to parse an RGB JSON, TR will handle requests with latest valid JSON configuration, but will set {fallback config} flag to 1. If the new JSON is valid, then the flag is set to 0. -* {allowed by whitelist/otherwise}: If a request is allowed by whitelist, this flag is set to 1; for all other cases, it is 0. - - -Example:: - - 1446442214.685 qtype=HTTP chi=129.100.254.79 url="http://ccr.geo2.cdn.com/live5.m3u8" cqhm=GET cqhv=HTTP/1.1 rtype=GEO rloc="-" rdtl=- rerr="-" rgb="N6G:1:X:0:0" pssc=302 ttms=3 rurl=http://cent6-44.geo2.cdn.com/live5.m3u8 rh="-" - - 1446442219.181 qtype=HTTP chi=184.68.71.9 url="http://ccr.geo2.cdn.com/live5.m3u8" cqhm=GET cqhv=HTTP/1.1 rtype=RGALT rloc="-" rdtl=- rerr="-" rgb="-:0:X:0:0" pssc=302 ttms=3 rurl=http://cent6-44.geo2.cdn.com/low_bitrate.m3u8 rh="-" - - 1446445521.677 qtype=HTTP chi=24.114.29.79 url="http://ccr.geo2.cdn.com/live51.m3u8" cqhm=GET cqhv=HTTP/1.1 rtype=RGDENY rloc="-" rdtl=- rerr="-" rgb="L4S:0:-:0:0" pssc=520 ttms=3 rurl="-" rh="-" - - http://git-wip-us.apache.org/repos/asf/incubator-trafficcontrol-website/blob/9694fb23/docs/latest/_sources/admin/quick_howto/steering.rst.txt ---------------------------------------------------------------------- diff --git a/docs/latest/_sources/admin/quick_howto/steering.rst.txt b/docs/latest/_sources/admin/quick_howto/steering.rst.txt deleted file mode 100644 index 1060f29..0000000 --- a/docs/latest/_sources/admin/quick_howto/steering.rst.txt +++ /dev/null @@ -1,95 +0,0 @@ -.. -.. -..

Specify the URL, username, password, and CDN name for the instance of Traffic Ops for which this Traffic Monitor is a member, and start the software. Once started with the correct configuration, Traffic Monitor downloads its configuration from Traffic Ops and begins polling caches. Once a configurable number of polling cycles completes, health protocol state is available via RESTful JSON endpoints. - - -Troubleshooting and log files -============================= -Traffic Monitor log files are in ``/opt/traffic_monitor/var/log/``, and tomcat log files are in ``/opt/tomcat/logs/``. http://git-wip-us.apache.org/repos/asf/incubator-trafficcontrol-website/blob/9694fb23/docs/latest/_sources/admin/traffic_ops_config.rst.txt ---------------------------------------------------------------------- diff --git a/docs/latest/_sources/admin/traffic_ops_config.rst.txt b/docs/latest/_sources/admin/traffic_ops_config.rst.txt deleted file mode 100644 index 0ca57da..0000000 --- a/docs/latest/_sources/admin/traffic_ops_config.rst.txt +++ /dev/null @@ -1,186 +0,0 @@ -.. -.. -..

Parameters are grouped in profiles and profiles are assigned to a server. For a typical cache there are hundreds of configuration settings to apply. The Traffic Ops parameter view contains the defined settings. To make life easier, Traffic Ops allows for duplication, comparison, import and export of Profiles. Traffic Ops also has a "Global profile" - the parameters in this profile are going to be applied to all servers in the Traffic Ops instance, or apply to Traffic Ops themselves. These parameters are: - - -.. index:: - Global Profile - -+--------------------------+---------------+---------------------------------------------------------------------------------------------------------------------------------------+ -| Name | Config file | Value | -+==========================+===============+=======================================================================================================================================+ -| tm.url | global | The URL where this Traffic Ops instance is being served from. | -+--------------------------+---------------+---------------------------------------------------------------------------------------------------------------------------------------+ -| tm.toolname | global | The name of the Traffic Ops tool.

Note:: The Traffic Server profiles contain some information that is specific to the hardware being used (most notably the disk configuration), so some parameters will have to be changed to reflect your configuration.

- -Regions, Locations and Cache Groups -=================================== -All servers have to have a `location`, which is their physical location. Each location is part of a `region`, and each region is part of a `division`. For Example, ``Denver`` could be a location in the ``Mile High`` region and that region could be part of the ``West`` division. Enter your divisions first in `Misc->Divisions`, then enter the regions in `Misc->Regions`, referencing the divisions entered, and finally, enter the physical locations in `Misc->Locations`, referencing the regions entered. - -All servers also have to be part of a `cache group`. A cache group is a logical grouping of caches, that don't have to be in the same physical location (in fact, usually a cache group is spread across minimally 2 physical Locations for redundancy purposes), but share geo coordinates for content routing purposes. JvD to add more. - - - -Configuring Content Purge -========================= -Content purge using ATS is not simple; there is no file system to delete files/directories from, and in large caches it can be hard to delete a simple regular expression from the cache. This is why Traffic Control uses the `Regex Revalidate Plugin <https://docs.trafficserver.apache.org/en/latest/admin-guide/plugins/regex_revalidate.en.html>`_ to purge content from the system. We don't actually remove the content, we have a check that gets run before each request on each cache to see if this request matches a list of regular expressions, and if it does, we force a revalidation to the origin, making the original content inaccessible. The regex_revalidate plugin will monitor it's config file, and will pick up changes to it without a `traffic_line -x` signal to ATS. Changes to this file need to be distributed to the highest tier (MID) caches in the CDN before they are distributed to the lower tiers, to prevent filling the lower tiers with the content that should be purged from the highe r tiers without hitting the origin. This is why the ort script (see :ref:`reference-traffic-ops-ort`) will by default push out config changes to MID first, confirm that they have all been updated, and then push out the changes to the lower tiers. In large CDNs, this can make the distribution and time to activation of the purge too long, and because of that there is the option to not distribute the `regex_revalidate.config` file using the ort script, but to do this using other means. By default, Traffic Ops will use ort to distribute the `regex_revalidate.config` file. - -Content Purge is controlled by the following parameters in the profile of the cache: - -+----------------------+-------------------------+--------------------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------+ -| Name | Config file | Description | Details | -+======================+=========================+==================================================+=========================================================================================================================================================+ -| location | regex_revalidate.config | What location the file should be in on the cache | The presence of this parameter tells ort to distribute this file; delete this parameter from the profile if this file is distributed using other means. | -+----------------------+-------------------------+--------------------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------+ -| maxRevalDurationDays | regex_revalidate.config | The maximum time a purge can be active | To prevent a build up of many checks before each request, this is longest time the system will allow | -+----------------------+-------------------------+--------------------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------+ -| regex_revalidate | plugin.config | The config to be used for regex_revalidate. | `regex_revalidate <https://docs.trafficserver.apache.org/en/5.3.x/reference/plugins/regex_remap.en.html>`_ | -| | | For example: --config regex_revalidate.config | | -+----------------------+-------------------------+--------------------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------+ - -Note that the TTL the adminstrator enters in the purge request should be longer than the TTL of the content to ensure the bad content will not be used. If the CDN is serving content of unknown, or unlimited TTL, the administrator should consider using `proxy-config-http-cache-guaranteed-min-lifetime <https://docs.trafficserver.apache.org/en/latest/admin-guide/files/records.config.en.html#proxy-config-http-cache-guaranteed-min-lifetime>`_ to limit the maximum time an object can be in the cache before it is considered stale, and set that to the same value as `maxRevalDurationDays` (Note that the former is in seconds and the latter is in days, so convert appropriately). - - - -.. _Creating-CentOS-Kickstart: - -Creating the CentOS Kickstart File -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -The kickstart file is a text file, containing a list of items, each identified by a keyword. You can create it by using the Kickstart Configurator application, or writing it from scratch. The Red Hat Enterprise Linux installation program also creates a sample kickstart file based on the options that you selected during installation. It is written to the file ``/root/anaconda-ks.cfg``. This file is editable using most text editors that can save files as ASCII text. - -To generate ISO, the CentOS Kickstart is necessary: - -1. Create a kickstart file. -2. Create a boot media with the kickstart file or make the kickstart file available on the network. -3. Make the installation tree available. -4. Start the kickstart installation. - -Create a ks.src file in the root of the selection location. See the example below: - -:: - - - mkdir newdir - cd newdir/ - cp -r ../centos65/* . - vim ks.src - vim isolinux/isolinux.cfg - cd vim osversions.cfg - vim osversions.cfg - - -This is a standard kickstart formatted file that the generate ISO process uses to create the kickstart (ks.cfg) file for the install. The generate ISO process uses the ks.src, overwriting any information set in the Generate ISO tab in Traffic Ops, creating ks.cfg. - -.. Note:: Streamline your install folder for under 1GB, which assists in creating a CD. - -.. seealso:: For in-depth instructions, please see `Kickstart Installation <https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/s1-kickstart2-howuse.html>`_ - - - - http://git-wip-us.apache.org/repos/asf/incubator-trafficcontrol-website/blob/9694fb23/docs/latest/_sources/admin/traffic_ops_extensions.rst.txt ---------------------------------------------------------------------- diff --git a/docs/latest/_sources/admin/traffic_ops_extensions.rst.txt b/docs/latest/_sources/admin/traffic_ops_extensions.rst.txt deleted file mode 100644 index 4aceebb..0000000 --- a/docs/latest/_sources/admin/traffic_ops_extensions.rst.txt +++ /dev/null @@ -1,88 +0,0 @@ -.. -.. -..
