After you change PHP 5 Handler to fcgi mode in cPanel,
Home » Service Configuration » Configure PHP and suEXEC
You can find the following error in the apache error log.
# tail -f /usr/local/apache/logs/error_logs
[warn] (13)Permission denied: mod_fcgid: spawn process /usr/local/cpanel/cgi-sys/php5 error
[error] (13)Permission denied: mod_fcgid: couldn’t bind unix domain socket /usr/local/apache/logs/fcgidsock/30113.5
The result of following command will be null in this case.
root@server [~]# netstat -plan | grep fcgi
Solution:
The issue is caused by the permission of /usr/local/apache/logs/fcgidsock directory. Change permission of ‘fcgidsock’ directory to 777 to solve the issue.
root@server [~]# cd /usr/local/apache/logs/
root@server [~]# chmod 777 fcgidsock
Check the error logs again to verify whether the issue is fixed.
If fcgi is running fine, you will get a result like following for the ‘netstat’ command.
root@server [~]# netstat -plan | grep fcgi
