三、安装配置数据库服务(MySQL)
[root@controller ~]# yum install -y mariadb mariadb-server MySQL-python
[root@controller ~]# cp /usr/share/mariadb/my-medium.cnf /etc/my.cnf #或者是/usr/share/mysql/my-medium.cnf
[root@controller ~]# vim /etc/my.cnf
[mysqld]
bind-address = 192.168.1.101
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
init-connect = 'SET NAMES utf8'
character-set-server = utf8
max_connections=1000
[root@controller ~]# systemctl enable mariadb.service && systemctl start mariadb.service #启动数据库服务，并将其配置为开机自启
[root@controller ~]# mysql_secure_installation #密码 123456，一路 y 回车
