How to troubleshoot Centmin Mod initial install issues (beta releases)

Centmin Mod is provided as is without support. I only work on Centmin Mod in my free time. So users feel free to help each other out which is the ideal goal of this community forum

Centmin Mod Logs
However, to properly troubleshoot and diagnose Centmin Mod initial install issues, you need to look deeper into the install logs which are automatically created when you run initial install menu option #1 or when you run any of the CLI install methods (from 1.2.3-eva2000.07 beta and onwards). These install logs are automatically created as per FAQ 7 outline at http://centminmod.com/faq.html

For example

Code:

ls -lhrt /root/centminlogs/
total 7.8M
-rw-r--r-- 1 root root  12K May 24 02:02 centminmod_1.2.3-eva2000.07_230514-155845_yuminstall_centos6.log

Troubleshooting Initial Install

To troubleshoot initial installation, you need to check the initial install log at /root/centminlogs and instructions under Sharing logs and errors heading for using Pastebin.com or Gists to share a sanitised version of the contents of the initial install log. You can see full details at How to troubleshoot Centmin Mod initial install issues

Example for 123.09beta01 and newer list /root/centminlogs files in date ascending order and grep for installer_*

Code (Text):

ls -lahrt /root/centminlogs | grep installer_*

example output returns install log at /root/centminlogs both a the full log and minimal log (smaller in size with some stuff filtered out)

Code (Text):

ls -lahrt /root/centminlogs | grep installer_*
-rw-r--r-- 1 root root 4.3M Jul 12 09:06 installer_120718-083445.log
-rw-r--r-- 1 root root 826K Jul 12 10:20 installer_120718-083445_minimal.log

Example for 123.08stable list /root/centminlogs files in date ascending order and grep for install.log

Code (Text):

ls -lahrt /root/centminlogs | grep install.log

example output returns install log at /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-112321_install.log

Code (Text):

ls -lahrt /root/centminlogs | grep install.log
-rw-r--r--  1 root root 2.2M Oct 11 01:40 centminmod_1.2.3-eva2000.09.001_111016-112321_install.log

in SSH use cat to ouput contents of /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-112321_install.log. Clear your SSH client window/buffer so only output is the contents of the file

for 123.08stable

Code (Text):

cat /root/centminlogs/centminmod_1.2.3-eva2000.09.001_111016-112321_install.log

for 123.09beta01 and newer

Code (Text):

cat /root/centminlogs/installer_120718-083445_minimal.log

Then copy and paste into Pastebin.com or Gists entry. If your SSH window scroll buffer isn't that large to get the whole contents of the install log, you can download file manually and copy and paste contents. But makes sure it's sanitised version of the contents of the initial install log as outlined at How to troubleshoot Centmin Mod initial install issues
