1、安装Mariadb
[root@localhost~]# yum -y install mariadb-server
2、启动服务并设置开机启动
[root@localhost~]# systemctl start mariadb
[root@localhost~]# systemctl enable mariadb
3、配置MariaDB
[root@localhost~]# mysql_secure_installation

[root@localhost~]# vi /etc/my.cnf
#在[mysqld]标签下添加
character-set-server=utf8mb4
[root@localhost~]# vi /etc/my.cnf.d/client.cnf
#在[client]标签下添加
default-character-set=utf8mb4
5、重启启动MariaDB服务
[root@localhost~]# systemctl restart mariadb
6、查看MariaDB字符编码
MariaDB[(none)]show variables like ‘%character%’;
7、卸载MariaDB数据库
[root@localhost~]# rpm -aq|grep mariadb
mariadb-libs-5.5.50-1.e17_2.x86_64
mariadb-5.5.50-1.e17_2.x86_64
mariadb-server-5.5.50-1.e17_2.x86_64
[root@localhost~]# yum -y remove mariadb*
