Zabbix-Agent restart no pid file...

[MrRobbert]

Hi All,

I run a Zabbix server, i have several host running, they are shown "available" in mij "host list". But then some hosts give me the next message instead of available:

Availability: "Not available"
Error: "Cannot connect to [host10] [Connection refused]"

Now when i logon to that machine and i try to restart the zabbix agent i get the following message:

root@VMWARESERVER01:/# /etc/init.d/zabbix-agent restart
Stopping Zabbix agent: zabbix_agentd
No process in pidfile `/var/run/zabbix/agentd.pid' found running; none killed.
Starting Zabbix agent: zabbix_agentd

Hi,

check if you have the directory '/var/run/zabbix/' and '/var/log/zabbix'
check the permissions of both directories.
I guess, the owner must be user 'zabbix' and group 'root' with 750 permissions.


I hope this help.

Hey...

this are my settings...

send 'ls -la' this include information of current directory.
if the user zabbix don't have permission to entry into /var/run/zabbix
777 in zabbix_agentd.pid, don't have effect.

[amcorreia]

....
I guess you are tring to run zabbix version 1.1.4, ok?

and if you run, just:
# ./zabbix_agentd -c <config_file>

[MrRobbert]

i dont know what i did, but i just restarted the server and suddenly it started to monitor that perticular server... i did everything here in this topic... i'll hope its stays monitored now...

anyway everyone tnx for youre help...

[MrRobbert]

Oke now its very strange, but now again i get the same message and my zabbix server doesnt reconnect again... Anybody knows what i can do about this?

[cadbury]

can you post a ls -al of the directories /var/run/zabbix and /var/log/zabbix ?

on your first post, in the config file, you have
PidFile=/var/run/zabbix/agentd.pid

but in your ls, it shows
/var/run/zabbix/zabbix_agentd.pid

not quite the same ...

[MrRobbert]

[cadbury]

ok

the owner of the /var/run/zabbix dir is root, and write acces is only set for root,
what i do is set zabbix as owner and don't change the rights, they are good.

assuming a user zabbix exists,
just make a
chown zabbix /var/run/zabbix/
and
chown zabbix /var/run/zabbix/*

to be fully correct, also run :
chmod 664 /var/run/zabbix/*

and for the log dir :
chmod 755 /var/log/zabbix/
chown zabbix /var/log/zabbix/*
chmod 664 /var/log/zabbix/*

I think that will make it
repost ls -al after modifications, just to be sure
