Rudder

Description:

"/etc/init.d/rudder-server-root status" returns no pid for postgres on ubuntu

Output of script:

# /etc/init.d/rudder-server-root status
Apache2 is running (pid 2713).
Jetty running pid=3318
rudder-agent[11680]: [INFO] Using /etc/default/rudder-agent for configuration
rudder-agent[11683]: [INFO] Using /var/rudder/cfengine-community for CFEngine workdir

The problem:

There is no postmaster process running:

# ps axf | grep postmaster | grep -v grep | cut -d" " -f 2
#

The processes that are running:

# ps axf | grep postgres | grep -v grep

Possible solutions:

# ps axf | grep postgres | grep -v grep | head -1 | cut -d " " -f 2
1075

A cleaner one in my humble opinion:

# head -1 /var/lib/postgresql/9.1/main/postmaster.pid
1075
