log-error = /home/mysql/logs/error.log
slow_query_log = on
slow_query_log_file = /home/mysql/logs/slow_query_log.log
long_query_time = 0.1
log_queries_not_using_indexes =1
long_query_time=2
character_set_server=utf8

[client]
port = 3306
socket = /var/lib/mysql/mysql.sock

[mysqldump]
quick
max_allowed_packet = 32M

2.4 初始化数据库

[root@monitor_53 ~]$ systemctl enable mariadb
[root@monitor_53 ~]$ systemctl start mariadb
[root@monitor_53 ~]$ mysql_secure_installation #初始化,配置完成root密码后,一路按Y即可
[root@monitor_53 ~]$ mysql_secure_installation 
Enter current password for root (enter for none): 回车
Set root password? [Y/n] 回车
New password: 123456
Re-enter new password: 123456
Remove anonymous users? [Y/n] 回车
Disallow root login remotely? [Y/n] 回车
Remove test database and access to it? [Y/n] 回车
Reload privilege tables now? [Y/n] 回车
Thanks for using MariaDB!

2.5 启动http

[root@monitor_53 ~]$ systemctl start httpd
[root@monitor_53 ~]$ systemctl enable httpd
[root@monitor_53 ~]$ netstat -ntap | egrep '(80|3306)'
