# systemctl start mariadb.service	//启动mariadb
# systemctl enable mariadb.service	//设置开机启动
# mysql_secure_installation	//mariadb配置,按需配置完毕后测试登陆
# lsof -i:3306	//查看端口监听情况
# mysql -uroot -p'your passwd'
//安装完毕，按需使用，后面用到的再补充

//补充1，授权命令
MariaDB [(none)]> create user 'your user name'@'localhost' identified by 'your passwd';
MariaDB [(none)]> grant all privileges on database_name.* to 'your user name'@'localhost' identified by 'your passwd';
MariaDB [(none)]> flush privileges;

//补充2
//配置mariadb字符集
//编辑 /etc/my.cnf.d/server.cnf 文件，在[mysqld]标签下添加如下内容：

init_connect='SET collation_connection = utf8_unicode_ci' 
init_connect='SET NAMES utf8' 
character-set-server=utf8 
collation-server=utf8_unicode_ci 
skip-character-set-client-handshake
lower_case_table_names=1

//编辑 /etc/my.cnf.d/client.cnf 文件，在[client]标签下加入如下内容：

default-character-set=utf8

//重启mariadb与验证
# systemctl restart mariadb.service
MariaDB [(none)]> show variables like "%character%";
MariaDB [(none)]> show variables like "%collation%";
