The above is only pasted part of the error log.
The above reason is because SELINUX starts
sestatus
SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: enforcing
Mode from config file: disabled
Policy MLS status: enabled
Policy deny_unknown status: allowed
Max kernel policy version: 28
The solution is as follows:
vim /etc/selinux/config
# 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 - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
Modify the SELINUX=disabledconfiguration file and close it permanently.
setenforce 0: Temporarily close SELINUX.
