one problem leads to another This is what i get when I run haproxy-systemd-wrapper on a linux command line. I could be wrong but the problem may be the option "-Ds" ? instead of just "D"? server:/haproxy-1.5.8 $ ./haproxy-systemd-wrapper -p /tmp/haproxy_pid.pid<7>haproxy-systemd-wrapper: executing /haproxy-1.5.8/haproxy -p /tmp/haproxy_pid.pid -Ds HA-Proxy version 1.5.8 2014/10/31Copyright 2000-2014 Willy Tarreau <[email protected]> Usage : haproxy [-f <cfgfile>]* [ -vdVD ] [ -n <maxconn> ] [ -N <maxpconn> ] [ -p <pidfile> ] [ -m <max megs> ] [ -C <dir> ] -v displays version ; -vv shows known build options. -d enters debug mode ; -db only disables background mode. -dM[<byte>] poisons memory with <byte> (defaults to 0x50) -V enters verbose mode (disables quiet mode) -D goes daemon ; -C changes to <dir> before loading files. -q quiet mode : don't display messages -c check mode : only check config files and exit -n sets the maximum total # of connections (2000) -m limits the usable amount of memory (in MB) -N sets the default, per-proxy maximum # of connections (2000) -L set local peer name (default to hostname) -p writes pids of all children to this file -de disables epoll() usage even when available -dp disables poll() usage even when available -dV disables SSL verify on servers side -sf/-st [pid ]* finishes/terminates old pids. Must be last arguments.
