Scenarios where problems are encountered

I was in the installation of Z-blog error, but also need to pay attention to, is to close selinux.

Because once the c_option.php creation fails, the Z-blog template is also not compiled, so this series of actions must be one go in order to install successfully.

by Setenforce 0 before the 3rd step, the temporary shutdown of SELinux can be successfully installed.
