启动mysql报错：

[root@localhost ~]# systemctl start mysqld
Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.

以下三种查看报错信息方式：

1. systemctl status mysqld.service

[root@localhost ~]# systemctl status mysqld.service

3.查看日志（推荐）：

[root@localhost ~]# cat /var/log/mysqld.log

解决方案：

[root@localhost ~]# getenforce    //查看selinux状态
Enforcing
[root@localhost ~]# setenforce 0    //临时关闭selinux，重启后失效

[root@localhost ~]# getenforce
Permissive
[root@localhost ~]# systemctl start mysqld     //启动mysql服务成功
[root@localhost ~]# ss -antulp | grep :3306
tcp    LISTEN     0      80     [::]:3306               [::]:*                   users:(("mysqld",pid=74057,fd=17))

永久关闭selinux

[root@localhost ~]# cat /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=enforcing
# 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

备份配置文件

[root@localhost ~]# cp -r /etc/selinux/config /etc/selinux/config.bak

[root@localhost ~]# sed -i 's/SELINUX=enforcing/\SELINUX=disabled/' /etc/selinux/config

[root@localhost ~]# cat /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
