第9章 Troubleshooting IdM server installation

Procedure

1. Use the tail command to display the last lines of a log file. The following example displays the last 10 lines of /var/log/ipaserver-install.log.

   [user@server ~]$ sudo tail -n 10 /var/log/ipaserver-install.log
   [sudo] password for user:
   value = gen.send(prev_value)
   File "/usr/lib/python3.6/site-packages/ipapython/install/common.py", line 65, in _install
   for unused in self._installer(self.parent):
   File "/usr/lib/python3.6/site-packages/ipaserver/install/server/init.py", line 564, in main
   master_install(self)
   File "/usr/lib/python3.6/site-packages/ipaserver/install/server/install.py", line 291, in decorated
   raise ScriptError()
   
   2020-05-27T22:59:41Z DEBUG The ipa-server-install command failed, exception: ScriptError:
   2020-05-27T22:59:41Z ERROR The ipa-server-install command failed. See /var/log/ipaserver-install.log for more information

2. To review a log file interactively, open the end of the log file using the less utility and use the ↑ and ↓ arrow keys to navigate. The following example opens the /var/log/ipaserver-install.log file interactively.

   [user@server ~]$ sudo less -N +G /var/log/ipaserver-install.log

3. Gather additional troubleshooting information by repeating this review process with the remaining log files.

   [user@server ~]$ sudo less -N +G /var/log/httpd/error_log
   
   [user@server ~]$ sudo less -N +G /var/log/dirsrv/slapd-INSTANCE-NAME/access
   
   [user@server ~]$ sudo less -N +G /var/log/dirsrv/slapd-INSTANCE-NAME/errors
