centos 7 安装 mariadb

yum安装mariadb
yum -y install mariadb mariadb-server

启动mariadb

systemctl start mariadb

设置开启启动

systemctl enable mariadb

初始化mariadb（设置root密码等等 跟着提示做）

mysql_secure_installation

2、配置MariaDB的字符集

文件/etc/my.cnf

vi /etc/my.cnf

在[mysqld]标签下添加

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

文件/etc/my.cnf.d/client.cnf

vi /etc/my.cnf.d/client.cnf

在[client]中添加

default-character-set=utf8

文件/etc/my.cnf.d/mysql-clients.cnf

vi /etc/my.cnf.d/mysql-clients.cnf

在[mysql]中添加

default-character-set=utf8

 全部配置完成，重启mariadb

systemctl restart mariadb

之后进入MariaDB查看字符集

mysql> show variables like "%character%";show variables like "%collation%";

显示为

+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client    | utf8                      |
