When I restarted HAProxy, I got random HTTP 503 although the backend servers were all working fine. By checking netstat, I saw that HAProxy was listening multiple times on the frontend ports. It seems that the init script coming with the installation does not work correctly. The processes are not terminated correctly when using stop (or restart, in this matter, either). Only with a kill I was able to correctly terminate the HAProxy processes. The following output should show more clarity: root@mylinux:~# netstat -lntp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 4653/haproxy tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 4221/haproxy tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 956/nginx tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 855/sshd tcp 0 0 0.0.0.0:8090 0.0.0.0:* LISTEN 4653/haproxy tcp 0 0 0.0.0.0:8090 0.0.0.0:* LISTEN 4221/haproxy tcp 0 0 0.0.0.0:8099 0.0.0.0:* LISTEN 4653/haproxy tcp 0 0 0.0.0.0:8099 0.0.0.0:* LISTEN 4221/haproxy tcp6 0 0 :::22 :::* LISTEN 855/sshd root@mylinux:~# service haproxy stop * Stopping haproxy haproxy [ OK ] root@mylinux:~# service haproxy status haproxy not running. root@mylinux:~# netstat -lntp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 4653/haproxy tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 4221/haproxy tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 956/nginx tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 855/sshd tcp 0 0 0.0.0.0:8090 0.0.0.0:* LISTEN 4653/haproxy tcp 0 0 0.0.0.0:8090 0.0.0.0:* LISTEN 4221/haproxy tcp 0 0 0.0.0.0:8099 0.0.0.0:* LISTEN 4653/haproxy tcp 0 0 0.0.0.0:8099 0.0.0.0:* LISTEN 4221/haproxy tcp6 0 0 :::22 :::* LISTEN 855/sshd root@mylinux:~# killall haproxy root@mylinux:~# netstat -lntp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 956/nginx tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 855/sshd tcp6 0 0 :::22 :::* LISTEN 855/sshd root@mylinux:~# service haproxy start * Starting haproxy haproxy [ OK ] root@mylinux:~# netstat -lntp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 8205/haproxy tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 956/nginx tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 855/sshd tcp 0 0 0.0.0.0:8090 0.0.0.0:* LISTEN 8205/haproxy tcp 0 0 0.0.0.0:8099 0.0.0.0:* LISTEN 8205/haproxy tcp6 0 0 :::22 :::* LISTEN 855/sshd root@mylinux:~# service haproxy restart * Restarting haproxy haproxy [ OK ] root@nzzad-lb01-test:~# netstat -lntp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 8286/haproxy tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 8205/haproxy tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 956/nginx tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 855/sshd tcp 0 0 0.0.0.0:8090 0.0.0.0:* LISTEN 8286/haproxy tcp 0 0 0.0.0.0:8090 0.0.0.0:* LISTEN 8205/haproxy tcp 0 0 0.0.0.0:8099 0.0.0.0:* LISTEN 8286/haproxy tcp 0 0 0.0.0.0:8099 0.0.0.0:* LISTEN 8205/haproxy tcp6 0 0 :::22 :::* LISTEN 855/sshd To manage notifications about this bug go to: https://bugs.launchpad.net/trusty-backports/+bug/1494141/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-ha Post to : ubuntu-ha@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-ha More help : https://help.launchpad.net/ListHelp
