Re: -sf/-st not working
It is totally normal that systemd kills the new process as the main one which was the first has exited. This is the expected behaviour. I'm currently patching haproxy to fully support systemd, I'll probably submit my patches by tomorrow (It's fully functionnal here, only needs a little cleaning) On 7 February 2013 16:31, Eugene Istomin wrote: > ** > > I think the main problem is in systemd: > > > > - from commandline -sf working as expected > > - from sysvinit -sf working as expected > > - from systemd -sf only stop process. > > > > I try both init.d & systemd scripts in systemd-based linux - all results > are the same: > > > > Loaded: loaded (/lib/systemd/system/haproxy.service; disabled) > > Active: failed (Result: signal) since Thu, 07 Feb 2013 17:18:43 +0200; > 12s ago > > Process: 28125 ExecReload=/usr/sbin/haproxy -D -f > /etc/haproxy/haproxy.cfg -p /var/run/haproxy.pid -sf $MAINPID (code=exited, > status=0/SUCCESS) > > Process: 28118 ExecStart=/usr/sbin/haproxy -D -f /etc/haproxy/haproxy.cfg > -p /var/run/haproxy.pid (code=exited, status=0/SUCCESS) > > Process: 28115 ExecStartPre=/usr/sbin/haproxy -c -q -f > /etc/haproxy/haproxy.cfg (code=exited, status=0/SUCCESS) > > Main PID: 28126 (code=killed, signal=KILL) > > CGroup: name=systemd:/system/haproxy.service > > > > > > systemd script: > > [Unit] > > Description=HAProxy For TCP And HTTP Based Applications > > After=network.target > > > > [Service] > > Type=forking > > PIDFile=/var/run/haproxy.pid > > ExecStartPre=/usr/sbin/haproxy -c -q -f /etc/haproxy/haproxy.cfg > > ExecStart=/usr/sbin/haproxy -D -f /etc/haproxy/haproxy.cfg -p > /var/run/haproxy.pid > > ExecReload=/usr/sbin/haproxy -D -f /etc/haproxy/haproxy.cfg -p > /var/run/haproxy.pid -sf $MAINPID > > > > [Install] > > WantedBy=multi-user.target > > > > -- > > Best regards, > > Eugene Istomin > > > > > On Thursday 07 February 2013 14:07:44 Baptiste wrote: > > > You should have a new HAProxy process started using the new > > > configuration and binding the ports... > > > > > > cheers > > > > > > On 2/7/13, Eugene Istomin wrote: > > > > Thanks for the answer, > > > > > > > > as written in > > > > http://www.mgoff.in/2010/04/18/haproxy-reloading-your-config-with- > > > > minimal-service-impact/ > > > > "The end-result is a reload of the configuration file which is not > visible > > > > by > > > > the customer" > > > > > > > > But in our case it leads to unbinding from all ports and finishing > haproxy > > > > process. > > > > Can this issue related to rpm build options?

Re: -sf/-st not working
I think the main problem is in systemd: - from commandline -sf working as expected - from sysvinit -sf working as expected - from systemd -sf only stop process.

Re: -sf/-st not working
You should have a new HAProxy process started using the new configuration and binding the ports... cheers On 2/7/13, Eugene Istomin wrote: > Thanks for the answer, > > as written in > http://www.mgoff.in/2010/04/18/haproxy-reloading-your-config-with- > minimal-service-impact/ > "The end-result is a reload of the configuration file which is not visible > by > the customer" > > But in our case it leads to unbinding from all ports and finishing haproxy > process. > Can this issue related to rpm build options?

Re: -sf/-st not working
Thanks for the answer, as written in http://www.mgoff.in/2010/04/18/haproxy-reloading-your-config-with- minimal-service-impact/ "The end-result is a reload of the configuration file which is not visible by the customer" But in our case it leads to unbinding from all ports and finishing haproxy process. Can this issue related to rpm build options? RPM build log is https://build.opensuse.org/package/rawlog?arch=x86_64&package=haproxy-1.5&project=server%3Ahttp&repository=openSUSE_12.2 -- Best regards, Eugene Istomin On Thursday 07 February 2013 07:28:17 Willy Tarreau wrote: > Hello Eugene, > > On Wed, Feb 06, 2013 at 08:29:33PM +0200, Eugene Istomin wrote: > > Hello, > > > > We have problem with reload/HUP: > > if i run #/usr/sbin/haproxy -D -f /etc/haproxy/haproxy.cfg -p > > /var/run/haproxy.pid -sf $(cat /var/run/haproxy.pid) - haproxy process is > > shutting down and exit > > This is the intended behaviour, it unbinds from its ports so that the new > process can bind, then waits for all existing connections to terminate > and leaves.

Hello,
We have problem with reload/HUP:
if i run #/usr/sbin/haproxy -D -f /etc/haproxy/haproxy.cfg -p
/var/run/haproxy.pid -sf $(cat /var/run/haproxy.pid) - haproxy process is
shutting down and exit
