Linux Troubleshooting – semanage command not found in CentOS 7/RHEL 7

Lately, I have been trying to make Apache server to listen to a different port other than it’s default port i.e 80. Once I made the necessary configurations and allowed the custom port via firewall, the apache server still refused to listen on the custom port. After a bit of googling, I figured out SELinux doesn’t allow the port, so I ran the following command to make the Apache server to listen on the different port.

semanage port -a -t ftp_port_t -p tcp 8090

Here, 8090 is port that I want Apache server to listen.

But it threw the following error:

-bash: semanage: command not found

I have no idea which package would provide ‘semanage’ command.

So, let us enter the following commands to figure out which package will provide this command.

yum provides /usr/sbin/semanage

Sample output:

yum whatprovides /usr/sbin/semanage

Sample output:

As you see in the above output, we need to install the package policycoreutils-python-2.2.5-11.el7_0.1.x86_64 in order to use ‘semanage’ command.

so, let us install policycoreutils-python-2.2.5-11.el7_0.1.x86_64 package using command:

yum install policycoreutils-python

    Thank you! I needed semanage after changing my webroot to a nonstandard path.
