1、启动MariaDB
安装完成MariaDB，首先启动MariaDB，两条命令都可以
systemctl start mariadb
或者
service mariadb start
设置开机启动
systemctl enable mariadb
或者：
chkconfig mariadb on
1
2、接下来进行MariaDB的相关简单配置
mysql_secure_installation
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
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]
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
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
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
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)
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。
