For the record:
- you can find the systemd unit file, including a Makefile that
installs it in contrib/systemd (requires building with USE_SYSTEMD=1)
- you can find the init.d script in examples/haproxy.init (but please
don't use it with systemd)
- haproxy-systemd-wrapper is no longer - it was removed from 1.8 and
newer. If you still have the file from previous installs, remove them.

Many improvements have been included for systemd over the years. Using
the proper unit file haproxy ships with is crucial.


cheers,

Hi Brain,

That seems to have worked!  Thanks!I did not know the wrapper was not
needed.  Let's see if it dies again ( hopefully not ) .

Thanks again!

Ah you don’t need haproxy-systemd-wrapper with 1.8 branch.

Here is my systemd script I use, note I don’t install in the standard location 
so you will have to tweak it for your environment.

# socket if you want seamless reloads.

Subject: HAproxy fails to start in CentOS with 'systemctl reload' ?

Hi,

I ran into this twice in last 2 days, where HAproxy fails to start in centOS 
7.5.  I compiled the latest stable from source and it did not have any startup 
scripts in the tarball that I downloaded. So, I broke up an older RPM file from 
fedora and used it /etc/init.d/haproxy script.  It works fine for 
stop/start/restart , etc. -- but I noticed that systemd is killing haproxy , 
mostl likely on 'reload' .

Here is 'systemctl status haproxy' output:

 haproxy.service - SYSV: HA-Proxy is a TCP/HTTP reverse proxy which is 
particularly suited for high availability environments.

Is there a different way this should be setup in centOS7.5 ? Some posts in GGL 
suggests a systemd-wrapper for HAproxy, but I do not see that in source tarball 
or I can't find it anywhere else.

Any suggestion would be very helpful.

Thanks.

Re: HAproxy fails to start in CentOS with 'systemctl reload' ?

[Imam Toufique]

Also, to add to this -- I tried creating a haproxy.service file, like
- /usr/lib/systemd/system/haproxy.service. and I added the contens below
like this:

[Unit]
Description=HAProxy Load Balancer
After=network.target

[Service]
ExecStartPre=/usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg -c -q
ExecStart=/usr/local/sbin/haproxy-systemd-wrapper -f
/etc/haproxy/haproxy.cfg -p /run/haproxy.pid
ExecReload=/bin/kill -USR2 $MAINPID
KillMode=mixed
Restart=always

[Install]
WantedBy=multi-user.target


after this I did a 'systemctl daemon-reload' .  When I try to start
haproxy now, I get this error ( see below ) :

root@crsplabnet2 sbin]# systemctl status haproxy
â— haproxy.service - HAProxy Load Balancer

/usr/local/sbin/haproxy-systemd-wrapper , of . course, does not exist,
hence the command fails .  I am not sure how to create that wrapper.  I
looked into a recently downloaded haproxy rpm , I did not see one there as
well .

Re: HAproxy fails to start in CentOS with 'systemctl reload' ?

Can you reply with the output of haproxy -vv

Need to know your compile options.

Subject: HAproxy fails to start in CentOS with 'systemctl reload' ?

Hi,

I ran into this twice in last 2 days, where HAproxy fails to start in centOS 
7.5.  I compiled the latest stable from source and it did not have any startup 
scripts in the tarball that I downloaded. So, I broke up an older RPM file from 
fedora and used it /etc/init.d/haproxy script.  It works fine for 
stop/start/restart , etc. -- but I noticed that systemd is killing haproxy , 
mostl likely on 'reload' .

Here is 'systemctl status haproxy' output:

 haproxy.service - SYSV: HA-Proxy is a TCP/HTTP reverse proxy which is 
particularly suited for high availability environments.
