apache cannot start after installing php on centos Solution:

After installing PHP, restart apache and report the following error

The reason is that Linux has a SELinux protection mode.

Syntax error on line 268 of /usr/local/apache2/conf/httpd.conf:
Cannot load /usr/local/apache2/modules/libphp5.so into server: /usr/local/apache2/modules/libphp5.so: cannot restore segment prot after reloc: Permission denied

Solution

1. Edit /etc/sysconfig/selinux and find:

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
SELINUX=enforcing

If SELINUX is already SELINUX=disabled, then there is no need to change it, otherwise Comment out SELINUX=enforcing and add a new line:

SELINUX=disabled

Save and exit.

2. How to not close SELINUX:

# setenforce 0
# chcon -c -v -R -u system_u -r object_r -t textrel_shlib_t /usr/local/apache/modules/libphp5.so
# service httpd restart
# setenforce 1
