You are running the semanage command and you get the output bellow :
[root@Linux ~]# semanage fcontext --at samba_share_t "/finance(/.*)?" -bash: semanage: command not found
Clearly the command is not installed, So you try to install it by running the command bellow, but there is no package with this name :
[root@kubernetes ~]# dnf install semanage Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.evoluso.com * extras: mirrors.evoluso.com * updates: mirror.librelabucm.org No package semanage available. Error: Nothing to do
In this article we will learn how to find the package provides semanage command on CentOS/RHEL.
What is semanage ?
It allows administrators to manage SELinux policies by configuring various settings, such as SELinux policy modules, file contexts, user mappings, and port mappings. This utility provides a high level of control over SELinux policies and is useful for managing complex security policies.
Find the package provides SELinux command
To install necessary packages for getting this tools run the following command :
[root@Linux ~]# yum provides /usr/sbin/semanage Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.evoluso.com * extras: mirrors.evoluso.com * updates: mirror.librelabucm.org policycoreutils-python-2.5-34.el7.x86_64 : SELinux policy core python utilities Repo : base Matched from: Filename : /usr/sbin/semanage
As you can see we need to install policycoreutils-python to to use our command :
[root@Linux ~]# yum install policycoreutils-python Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.evoluso.com * extras: mirrors.evoluso.com * updates: mirror.librelabucm.org Resolving Dependencies --> Running transaction check ---> Package policycoreutils-python.x86_64 0:2.5-34.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ================================================================================================================================================================================================================== Package Arch Version Repository Size ================================================================================================================================================================================================================== Installing: policycoreutils-python x86_64 2.5-34.el7 base 457 k Transaction Summary ================================================================================================================================================================================================================== Install 1 Package Total download size: 457 k Installed size: 1.2 M Is this ok [y/d/N]:
Once the package is installed, you can use the command, and that’s it.
