Haproxy 1.7.10 upgrade to 1.8.15 fails to start


#1

Hello,

We currently run Haproxy 1.7.10 on Debian 9.4 Stretch. We have used Haproxy for Load Balancing for about 4 to 5 years now without much of an issue. We recently read that starting in 1.8 band Haproxy can be multi threaded when ran vs single threaded, so we want to try to take advantage of this.

Unfortunately I am running into some errors when upgrading to 1.8. I do not get any configuration errors, so I believe our haproxy.cfg file is good, but I will post the rest of the errors I am getting below. I can go through the upgrade process like we have done many times, but at the end the Haproxy service fails to start.

#2

Also if I roll back the build to 1.7.10, I do not have the starting error. So it appears something from 1.8 and on has changed.

Thanks


#3

1.7 and 1.8 has a very different startup procedure, that’s why you need:

  • compile haproxy 1.8 with systemd support (USE_SYSTEMD=1)
  • update the systemd unit file (in your case, cp contrib/systemd/haproxy.service.in /etc/systemd/system/haproxy.service && systemctl daemon-reload)
  • remove the old haproxy-systemd-wrapper executable, which doesn’t exist in 1.8 anymore

#4

Thank you for the reply. I am still having a few issues, so I am just trying to make sure I understand what your saying. I need to compile Haproxy with USE_SYSTEMD=1:

make TARGET=linux2628 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 LDFLAGS=-ldl SSL_INC=/opt/openssl/include SSL_LIB=/opt/openssl/lib USE_SYSTEMD=1

Then you say to replace the Haproxy.service file from /etc/system/system/ then replace it from the contrib/systemd/haproxy.service.in?

Thanks


#5

Yes.

Replace the old system unit file from haproxy 1.7, which in your case is in /etc/systemd/system/haproxy.service with the updated file from haproxy 1.8.

Also delete haproxy-systemd-wrapper in your path.


#6

Thank you for the help. I was able to get Haproxy to start with these steps.

Thanks
