Talk:Install Zenoss

firewall

If you did a manual install of Centos 6.3, the firewall will be enabled by default, and you will not be able to connect to the Zenoss web page on port 8080 until you disable it:

1. service iptables save
2. service iptables stop
3. chkconfig iptables off

Updated end-of-install docs

I have tweaked the auto-deploy script to provide firewall info after it completes successfully. See https://github.com/zenoss/core-autodeploy/commit/3e85d4b17de3f06dc40ed56dd1f914b70aa5ec1e

Command failure: /sbin/service zenoss start

Hello,

I have try to install Zenoss with the auto-script, but I have this issue:

Starting MySQL SUCCESS! Zenoss not initialized. Performing first-boot initialization... Fresh install pre steps Please confirm that the JRE in the PATH is Oracle's version. Command failure: /sbin/service zenoss start

Thank you for your help.

Edit: I am on a Centos 6.3

This should now be fixed - you probably had java-openjdk installed. The updated version of the script should now remove it first so that it will find the Oracle JRE. -DR

Command failure: /sbin/service zenoss start - 2nd observation

Failes for me to!

Try again - I have confirmed the URL is correct and this path exists. This may have been due to a sourceforge quirk at the time. - DR

mysql service

on 64 bit centos 6.3 I had to modify installation script so it started mysqld service, because mysql service didn't exist. I also noticed a bunch of notifications for setting env variables trying to access /usr/local/zenoss, while installation was put in /opt/zenoss. But it works anyway.

Centos 6.3 base install mysql-libs

I did a base install of Centos 6.3 using the netinstall image and choosing minimal. I did not install any other packges except wget. When I ran the Auto Deploy script it said it couldn't continue because I had an older version of the mysql-libs library installed. I used yum to remove them which also removed postfix. After doing this the Auto Deploy script ran fine, however now I don't have postfix installed, if I try to do a yum to install it again it wants to install mysql-libs, and I"m not sure if this will break the Zenoss install.

-- I found that if I do a yum remove mysql-libs it removes many packages, however, if I followed it up with a "yum install sysstat" (one of the packages it removed) it added them all back, except mysql-libs

-- I replace postfix with sendmail, thus #yum install sendmail; yum remove mysql-libs

  Then only mysql-libs and postfix removed, not cron packages as well.

I have created the following bug to track this issue: http://jira.zenoss.com/jira/browse/ZEN-3064

Centos 6.3 rabbit-mq issue

[root@Muon-Z ~]# chkconfig iptables off [root@Muon-Z ~]# service rabbitmq-server start Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_{log, _err} rabbitmq-server.

in the /var/log/rabbitmq/ startup_log I get

Activating RabbitMQ plugins ... 0 plugins activated:

ERROR: epmd error for host "Muon-Z": address (unable to establish tcp connection)

How is this corrected?

The solution is by adding the server name in the hosts file
