Disabling SELinux

SELinux may restrict the access permission of applications. Therefore, disable SELinux to ensure that applications run properly. Disabling SELinux may impair system security and make the system more vulnerable to potential security problems and attacks. Assess the potential risks before disabling SELinux. Perform the operations in this section on all nodes.

• Disable SELinux temporarily.

  setenforce 0

• Disable SELinux permanently.
  1. Modify the configuration file to permanently disable SELinux:

     1 2	sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config cat /etc/selinux/config

     If "SELINUX=disabled" is displayed, as shown in the following figure, the modification is successful.

     

  2. After SELinux is disabled, restart the server.
