Fix lỗi semanage không run trên Centos 7

By default, SELinux only allows port 22 for SSH. What you need to do is enable the newly created port through SELinux. To do that, run the commands below

sudo semanage port -a -t ssh_port_t -p tcp 2244

If you run the commands above and get an error that semanage command not found, run the commands below to install it.

sudo yum -y install policycoreutils-python

Then go and run the semange commend again to allow the new port through SELinux.
