I started tinkering with haproxy-systemd-wrapper recently and noticed
that I get two haproxy processes when I start:
# systemctl start haproxy
# systemctl status haproxy
haproxy.service - HAProxy Load Balancer
Loaded: loaded (/usr/lib/systemd/system/haproxy.service; disabled)
Active: active (running) since Sat 2014-02-15 10:39:20 CST; 1s ago
Main PID: 10065 (haproxy-systemd)
CGroup: /system.slice/haproxy.service
├─10065 /usr/sbin/haproxy-systemd-wrapper -f
/etc/haproxy/haproxy.cfg -p /run/haproxy....
├─10066 /usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg -p
/run/haproxy.pid -Ds
└─10067 /usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg -p
/run/haproxy.pid -Ds
That doesn't seem right. A quick look the haproxy processes shows an
interesting parent/child relationship:
# ps -C haproxy -o pid,ppid
PID PPID
10066 10065
10067 10066
Can someone explain what is going on here? I'm using 1.5-dev22 and the
systemd service file from the source.
Thanks.
