1、安装
yum -yinstallmariadb mariadb-server
2、设置开机启动并启动
systemctl enable mariadb
systemctl start mariadb
3、配置数据库
mysql_secure_installation
Enter current password for root (enter for none) 设置密码第一次直接回车
move anonymous users? [Y/n] 删除匿名用户
Disallow root login remotely? [Y/n] 禁止root远程登录
Remove test database and access to it? [Y/n] 删除test数据库
Reload privilege tables now? [Y/n] 重新加载权限表
3、测试是否可以登陆
mysql -u用户名 -p密码
4、配置字符集支持 utf8mb4支持emoji
vi /etc/my.cnf
[client]
default-character-set = utf8mb4
[mysql]
default-character-set = utf8mb4
[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
skip-character-set-client-handshake
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
init_connect='SET NAMES utf8mb4'
vi /etc/my.cnf.d/client.cnf
[client]
default-character-set = utf8mb4
vi /etc/my.cnf.d/mysql-clients.cnf
[mysql]
default-character-set = utf8mb4
5、 重启
systemctl restart mariadb
6、登陆测试,命令别忘记分号
mysql -u用户名 -p密码
show variables like"%character%";
show variables like"%collation%";
输入正常为下面这种
