Hello!

64-Bit CentOS 6.4, Manual Install of 2012R2.3.

The fullinstall command completed successfully, however, when I add a host and do "Apply Configuration", the "Waiting for configuration verification...." line spins forever.

This is a fresh install, there is nothing other than the install defaults in the config - the only host listed is 'localhost' until I add one and try to Apply.

Running /nagiosql/admin/verify.php directly, I instantly see the output, and see any errors.

In addition, I see the errors in the "Configuration Snapshots" area, but when I try to delete the configs with errors, it says "Config Snapshot Deleted", but it still appears in both the list and on the filesystem - whereas on my other installs it does in fact delete it.

I've fun 'fix-nagiosadmin' from the install dir, and I see that I have a valid config, but I still can't apply it from the Core Config Manager.

It feels like there is a permissions problem somewhere.

I looked in /usr/local/nagiosxi/nom/checkpoints/nagioscore, and I can see the list of config snapshots and errors:

Code: Select all

664226 drwxr-xr-x 2 nagios nagios  4096 Sep  9 09:06 .
664225 drwxr-xr-x 3 nagios nagios  4096 Sep  9 09:08 ..

664171 -rw-r--r-- 1 nagios nagios  2799 Sep  9 09:06 1378739165.txt

I ran 'check file permissions' from the Core Config Manager, and it shows green.

Any idea what I can check next for this one?

Thanks!

Hmm, you may be running into some database issues here. Did you offload the mysql database to a remote server?

Please run through this document and then try to apply configuration again:

http://assets.nagios.com/downloads/nagi ... tabase.pdf

If it still hangs, run the following:

Code: Select all

tail -f /var/log/httpd/error_log

Then try to apply configuration, after it hangs, break the tail and send us the output here in addition to the output of the following command:

Code: Select all

tail -30 /var/log/mysqld.log

Thanks!

Ok - it looks like the error from the httpd error_log is:

Code: Select all

[Mon Sep 09 10:12:53 2013] [error] [client 155.70.39.45] PHP Warning:  mysql_pconnect(): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in /usr/local/nagiosxi/html/db/adodb/drivers/adodb-mysql.inc.php on line 383, referer: http://<redacted ip>/nagiosxi//includes/components/nagioscorecfg/applyconfig.php?cmd=confirm

Any thoughts on where to start troubleshooting that socket connection?

Database is local on machine, no customizations...

I ran through all these fixes, to no avail (including just making sure it was running):

What are you php.ini settings for memory, execution, etc?

Code: Select all

grep "memory_limit\|max_execution\|max_input" /etc/php.ini

Disks & PHP look ok:

Well, just to be 100% sure, lets make sure you can access the socket file, and that mysql is started.

Code: Select all

service mysql status
ll /var/lib/mysql/mysql.sock

Posted: **Mon Sep 09, 2013 1:11 pm**

Ok - here's the output:

Code: Select all

[root@ecca2 etc]# service mysql status
mysql: unrecognized service

[root@ecca2 etc]# service mysqld status
mysqld (pid  10143) is running...

[root@ecca2 etc]# ll /var/lib/mysql/mysql.sock
srwxrwxrwx 1 mysql mysql 0 Sep  9 10:31 /var/lib/mysql/mysql.sock

[root@ecca2 etc]# mysql --version

Posted: **Mon Sep 09, 2013 2:07 pm**

Also:

Confirmed that /etc/sysconfig/selinux is set to disabled, and that php has --enable-sockets.

Can you run the following command and show us the output?
