I am using CentOS 7 and have set up a duplicate Apache instance using the systemd structure there.

I can get both Apaches to run if I use setenforce 0. However, when I setenforce 1, the new Apache won't start.

I did my best to go through all the files I created and I have copied the SELinux type across using "ls -Z" and then chcon to the same as httpd.

The failure message I am getting is:

[Thu Jun 23 23:51:24.123185 2016] [core:notice] [pid 24944] SELinux policy enabled; httpd running as context system_u:system_r:httpd_t:s0

But the location has the httpd context:

[root~]# ls -Z /etc | grep httpd
drwxr-xr-x. root root system_u:object_r:httpd_config_t:s0 httpd
drwxr-xr-x. root root unconfined_u:object_r:httpd_config_t:s0 httpd-bobby

I know it is SELinux because it works with setenforce 0. What am I doing wrong?

There are multiple httpd contexts and this isn't the right one.

The directory in which the pid file goes should have the context httpd_var_run_t .

I'd recommend against putting it in /etc and create one in /var/run.

To set the correct context permanently for example for /var/run/httpd-bobby:

semanage fcontext -a -t httpd_var_run_t "/var/run/httpd-bobby(/.*)?" && restorecon /var/run/httpd-bobby

    You don't need to add a new regex. Policy allows httpd_t to write to var_run_t so just creating /var/run/httpd-bobby with suitable permissions should to the trick. – Iain Jun 25 '16 at 12:24
  • @Iain Thanks, didn't fully check the policy – RPDiep Jun 25 '16 at 12:34
