Hi,

I have installed zenoss and started the services successfully.
However, the web url am still not able to access. Please help me out.

Note: Connectivity to the port 8080 is already opened.

*[***@hostname /]# wget -- http://hostname:8080/ http://hostname:8080*

What does 'service zenoss restart' show when run as root?

Daemon: zopectl daemon manager not running is your problem.  Try accessing it now?  If this fails you have a zope problem beyond my knowledge to fix.

Ramu,

Zenoss doesn't provide phone support for Zenoss Core, and I'm not quite sure why skype won't start.  My next suggestion would be to start from scratch, get the centos 6.3 64 bit livecd, and run the community install script.  http://wiki.zenoss.org/Install_Zenoss http://wiki.zenoss.org/Install_Zenoss.

Hi Andrew,

Thanks for the reply. Here we are using RHEL 6.3 for the zenoss core 4.2.0. I'm seeing the below log in event.log file for zopectl. Request you to help me out in this regard.

Ramu,

I don't think you have mysql started, or possibly set up correctly.  Again, please use the setup script on a CLEAN centos 6.3 64 bit install and you will save yourself a lot of time and frustration.  I don't know what steps you've taken to install Zenoss, but you have a lot missing.

Hi Andrew,

Mysql is already started but still getting the error. Here we have RHEL 6.3 OS, please let me know the compatable installable name and location for the zenoss on this.

Awaiting for the response.

Thank you!!

Ramu

This just started happening to me today on my CentOS 6.3 (same as RHEL 6.3) installation. I made no changes to the server, no recent zenpack installations, and it's been running fine for a month. Very frustrating! Anyone have a fix for this problem where zenhub appears it cannot connect to MySQL on local socket anymore? Again, no changes and MySQL is running just fine and I've connected to it just fine and even ran mysqlcheck without issues.

zeneventserver-stdio.2013_01_10.log:org.springframework.jdbc.UncategorizedSQLException: StatementCallback; uncategorized SQLException for SQL [ ALTER TABLE event_time ADD PARTITION (PARTITION p20130110_230000 VALUES LESS THAN(1357858800000))]; SQL state [HY000]; error code [23]; Out of resources when opening file './zenoss_zep/' (Errcode: 24); nested exception is java.sql.SQLException: Out of resources when opening file './zenoss_zep/' (Errcode: 24)

Ah ha! So mysql is running out resources adding a partition to the umpty-squat table. And my server is not out of space by a long shot, so this must be a "max files opened" sort of issue.

Low and behold, I added these statements to my server's setup:

/etc/security/limits.conf

mysql          soft     nofile          65536
mysql          hard     nofile          65536

Followed by adding this to my mysql configuration file:

/etc/my.cnf

open_files_limit = 65536

And restarting mysql (as root: service mysql restart) and then restarting zenoss (service zenoss restart) and, voila, all my errors went away and I can logon to Zenoss mgmt interface again.

Wow - so this reveals to me that the my.cnf (MySQL configuration) is not really optimized or tailored to large environments (or at least more than 100 devices being monitored).
