SELinux (security-enhanced Linux) security-enhanced Linux is an implementation of mandatory access control (mandatory access controls). In this kind of control, Linux has a lot of operations that can be banned or unsuccessful. Before the installation of CentOS under the vsftpd how can not get up. Then the SELinux and then finished. All right, cut the crap, let's talk about how to get rid of

Configure Nginx today and then always prompt permission, clearly gave 777 permissions. Always still not, re-installed a few times, the last thought may be the result of SELinux. Just turn off SELinux and everything is fine.It's not clear what SELinux is, it's just that the security Linux is meant to make Linux more secure, but this thing can cause some problems.
To reduce commissioning time, quickly deploy server environments, and sometimes we need to temporarily turn off SELinux1.
