How to Fix ‘semanage: command not found’ Error in CentOS/RHEL/OEL

 I was configuring ssh port and has to channge the security context values using semanage command , but i was welcomed by a semanage command not found error.

[root@ftp1 ~]# semanage port -a -t ssh_port_t -p tcp 5600

-bash: semanage: command not found

[root@ftp1 ~]#

semanage is an SELinux (Security-Enhanced Linux) management tool that is used to configure specific elements without making any adjustments to or reassembling from policy sources. 

In this article, I will explain how to install necessary packages for getting semanage command using the yum command.

[root@ftp1 ~]# yum provides /usr/sbin/semanage

policycoreutils-python-utils-2.8-16.1.0.1.el8.noarch : SELinux policy core python utilities

Repo        : ol8_baseos_latest

Matched from:

Filename    : /usr/sbin/semanage

As the above command suggests we need to install policycoreutils-python-utils-2.8-16.1.0.1.el8.noarch. 

[root@ftp1 ~]# yum install policycoreutils-python-utils

Once the installation is complete, try running the semanage command again, it should work.
