2.3 设置开机启动
systemctl enable mariadb
3 简单配置
mysql_secure_installation
3.1 设置密码

3.3 测试登录
mysql -uroot -ppassword
本次测试的用户名为root ,密码为 *******
4 配置字符集
4.1 /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
4.2 /ETC/MY.CNF.D/CLIENT.CNF
在[client]中添加
default-character-set=utf8
4.3 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
4.4 重启MARIADB
systemctl restart mariadb
4.5 查看字符集
mysql -uroot -p*******
show variables like "%character%";show variables like "%collation%";
显示：
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
+----------------------+-----------------+
| Variable_name | Value |
+----------------------+-----------------+
| collation_connection | utf8_unicode_ci |
| collation_database | utf8_unicode_ci |
| collation_server | utf8_unicode_ci |
+----------------------+-----------------+
3 rows in set (0.00 sec)
出现以上，则字符集配置完成
5 设置权限
5.1 创建用户命令
create user demo@localhost identified by '******';
5.2 直接创建用户并授权的命令
grant all on . to demo@localhost identified by '******';;
5.3 授予外网登录权限
grant all privileges on . to demo@'%' identified by '******';;
5.4 授予权限并且可以授权
grant all privileges on . to demo@'%' identified by '******'; with grant option;
5.5 刷新权限
flush privileges;
5.6 限制用户使用指定数据库
use mysql
CREATE USER 'study'@'localhost' IDENTIFIED BY 'asb#1234';
GRANT SELECT, INSERT, UPDATE, REFERENCES, DELETE, CREATE, DROP, ALTER, INDEX, CREATE VIEW, SHOW VIEW ON study.* TO 'study'@'localhost' identified by '******';;
GRANT SELECT, INSERT, UPDATE, REFERENCES, DELETE, CREATE, DROP, ALTER, INDEX, CREATE VIEW, SHOW VIEW ON study.* TO 'study'@'%' identified by '******';;
