I ran a yum update after which HTTP Apache server fails to start up on my Centos 7 VM.

The apache details - Apache/2.4.6 (CentOS) OpenSSL/1.0.1e-fips PHP/5.4.16

Kernel version - 3.10.0-327.10.1.el7.x86_64

Here is what the systemctl shows. I'm not able to figure out what is broken after the update.

[root@localhost log]# systemctl status httpd.service

Could I please request help to get some pointers to dig further or anyone who has seen this before & knows how to fix please?

  • Please provide the apache/httpd logs in /var/log/httpd/ directory so we can figure out the problem. Commented Mar 14, 2016 at 10:06
  • use apachectl -t (for testing the configs), that usually gives useful hints as to where the configuration errors are Commented Mar 14, 2016 at 13:18
  • Hello - Sorry for the delay in coming back. I did not have time to retry. I upgraded another VM of Centos& & can replicate the problem. I've updated the question with error logs & output from journal -xe command. Looks like a bunch of permission errors but don't know what these are. I have disabled SE linux mode.

Check the /var/log/httpd logs and if not check the "yum update" again.then restart the httpd service .check /var/log/messages and /var/log/httpd and yum log.So, you can identify the issue.

  • The file you're interested in is /var/log/httpd/error_log - this is where you'll see the error preventing Apache to start.
