Upstart Script for zabbix

[scanch]

Hello,

Here are simple upstart scripts (tested under ubuntu 10.04.1 server) for zabbix-server and zabbix-agent.
Any feedback & suggestions are welcomed.

zabbix-agent.conf:

# zabbix-agent - Start zabbix agent
description     "Zabbix Agent"
author          "S. CANCHON"
start on runlevel [2345]
stop on runlevel [016]
respawn
expect daemon
exec /usr/sbin/zabbix_agentd

zabbix-server.conf:

# zabbix-server - Start zabbix server
description     "Zabbix Server"
author          "S. CANCHON"
start on (runlevel [2345]
          and started mysql)
stop on runlevel [016]
respawn
expect daemon
exec /usr/sbin/zabbix_server

Just have to copy them in /etc/init/ and control them with upstart tools.

Additional section for those, who store pid files not in the default directory

I store zabbix pid files in /var/run/zabbix. So i added

pre-start script
  if [ ! -d /var/run/zabbix ]; then
        mkdir -p /var/run/zabbix
    chown zabbix:zabbix /var/run/zabbix
    chmod 755 /var/run/zabbix
  fi
end script

between "respawn" and "expect daemon"

pretty simple indeed
would it be ok to add these to the zabbix distribution, in case they are useful for somebody else ?

[sYB-tyumen]

I think, yes.
It is confusing when I see that zabbix has been tested on Ubuntu and there are no upstart jobs in installation packet.

But there are 2 things to pay attention for:
1) /var/run/zabbix is not a default path for pid files
2)

          and started mysql)

does NOT guarantee that zabbix server process will be able to connect to mysql. It only means that zabbix server process starts after mysql process (if your database is large enough, myslq can be started, but not ready to accept connections). May be a little pause (or better some mysql connection test) will be suitable before “exec” statement.

how do other software packages handle that ?

You might also want to check the Fedora RPM for Zabbix. Fedora has also moved to upstart. It might also be a good reference point.

could you please post the examples here ? is there some common way to deal with database availability when starting up ?

[sYB-tyumen]

One of the methods is listed in zabbix agent's configuration file.

I tried this in a pre-start section of upstart job:

  ZabbixConfig=/etc/zabbix/zabbix_server.conf
  DBuser=""
  DBpassword=""

  if [ -f $ZabbixConfig ]
  then
    DBuser=`cat $ZabbixConfig | grep '^DBUser='`
    DBuser="${DBuser##*=}"
    DBpassword=`cat $ZabbixConfig | grep '^DBPassword='`
    DBpassword="${DBpassword##*=}"

    if [ -n "$DBuser" ] && [ -n "$DBpassword" ]
    then

      i=0

      while [ i -le 5 ]
      do
        Test=`mysqladmin -u$DBuser -p$DBpassword ping|grep alive|wc -l`

        if [ $Test=1 ]
        then
          i=100
        else
          sleep 5
          i=`expr $i + 1`
        fi
      done
    fi
  fi

Tried "for" loop with "break" when $Test=1, but it looks like "break " statement breaks entire upstart job execution.

added the files from the first post to svn.

Hi all!
I'm new of upstart and I have the same problem with MySQL and Zabbix on Ubuntu Server 10.04.2

Can you post the entire correct scripts and the shell command to configure them please?

Many thanks!

[g.vecchi]

Ok, I've created working configurations files.

See attachments.

stop on runlevel [016]
respawn
expect daemon
exec /usr/sbin/zabbix_server

Just have to copy them in /etc/init/ and control them with upstart tools.

I copied it to /etc/init.d and then did the following...


root@zabbix01:/etc/init.d# update-rc.d zabbix-server defaults
update-rc.d: warning: /etc/init.d/zabbix-server missing LSB information
update-rc.d: see <http://wiki.debian.org/LSBInitScripts>
Adding system startup for /etc/init.d/zabbix-server ...
/etc/rc0.d/K20zabbix-server -> ../init.d/zabbix-server
/etc/rc1.d/K20zabbix-server -> ../init.d/zabbix-server
/etc/rc6.d/K20zabbix-server -> ../init.d/zabbix-server
/etc/rc2.d/S20zabbix-server -> ../init.d/zabbix-server
/etc/rc3.d/S20zabbix-server -> ../init.d/zabbix-server
/etc/rc4.d/S20zabbix-server -> ../init.d/zabbix-server
/etc/rc5.d/S20zabbix-server -> ../init.d/zabbix-server

Then when I do /etc/init.d/zabbix-server start I get the following...


root@zabbix01:/etc/init.d# /etc/init.d/zabbix-server start
/etc/init.d/zabbix-server: line 2: description: command not found
/etc/init.d/zabbix-server: line 3: author: command not found
/etc/init.d/zabbix-server: line 4: syntax error near unexpected token `('
/etc/init.d/zabbix-server: line 4: `start on (runlevel [2345]'

Any ideas?

Kind regards,

You have to copy them into /etc/init NOT /etc/init.d

Bye!

Thanks for what should have been obvious
