1、启动MariaDB

安装完成MariaDB，首先启动MariaDB，两条命令都可以

systemctl start mariadb
1

或者

service mariadb start
1

设置开机启动

systemctl enable mariadb
1

或者：

chkconfig mariadb on
1

2、接下来进行MariaDB的相关简单配置

mysql_secure_installation
1

首先是设置密码，会提示先输入密码

Enter current password for root (enter for none):<–初次运行直接回车

设置密码

Set root password? [Y/n] <– 是否设置root用户密码，输入y并回车或直接回车
New password: <– 设置root用户的密码
Re-enter new password: <– 再输入一次你设置的密码
1
2
3

其他配置

Remove anonymous users? [Y/n] <– 是否删除匿名用户，回车

Disallow root login remotely? [Y/n] <–是否禁止root远程登录,回车,

Remove test database and access to it? [Y/n] <– 是否删除test数据库，回车

Reload privilege tables now? [Y/n] <– 是否重新加载权限表，回车

初始化MariaDB完成，接下来测试登录

mysql -uroot -p [回车，之后输入密码]
1

完成。

3、配置MariaDB的字符集

设置客户端：

vim /etc/my.cnf.d/mysql-clients.cnf
[mysql]
default-character-set=utf8
1
2
3
4
5

设置服务端：

vim /etc/my.cnf.d/server.cnf
[mysqld]
init_connect='SET collation_connection = utf8_general_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_general_ci
skip-character-set-client-handshake
#开启慢查询
slow_query_log = ON
slow_query_log_file = /usr/local/mysql/data/slow.log
long_query_time = 1
1
2
3
4
5
6
7
8
9
10
11
12
13
14

全部配置完成，重启mariadb

systemctl restart mariadb
1

之后进入MariaDB查看字符集

mysql> show variables like "%character%";show variables like "%collation%";
1

显示为

MariaDB [(none)]> show variables like "%character%";show variables like "%collation%";
+--------------------------+----------------------------+
| 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_general_ci |
| collation_database | utf8_general_ci |
| collation_server | utf8_general_ci |
+----------------------+-----------------+
3 rows in set (0.00 sec)
1

12
13
14
15
16
17
18
19
20
21
22
23
24
25

字符集配置完成。

4、添加用户，设置权限

创建用户命令

mysql>create user username@localhost identified by 'password';
1

直接创建用户并授权的命令

mysql>grant all on *.* to username@localhost indentified by 'password';
1

授予外网登陆权限，但不能二级授权；

mysql>grant all privileges on *.* to username@'%' identified by 'password';
1

授予权限并且可以二次授权

mysql>grant all privileges on *.* to username@'hostname' identified by 'password' with grant option;
1

简单的用户和权限配置基本就这样了。

其中只授予部分权限把 其中 all privileges或者all改为：

select,insert,update,delete,create,drop,index,alter,grant,references,reload,shutdown,process,file

其中一部分。
