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

[Imam Toufique]

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.

Can you reply with the output of haproxy -vv

Need to know your compile options.

Hi,
I ran into this twice in last 2 days, where HAproxy fails to start in

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' .

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.

[Unit]

After=syslog.target network.target

[Service]
# You can point the environment variable HAPROXY_STATS_SOCKET to a stats
# 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.

Hello,

Post by Imam Toufique
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!

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,

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]

After=network.target

[Service]

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 ) :

***@crsplabnet2 sbin]# systemctl status haproxy

/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 .

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' .
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.
