centos7 yum 安装 MariaDB

Posted 2020-09-04

1、安装MariaDB

yum -y install mariadb mariadb-server

安装完成MariaDB，首先启动MariaDB
systemctl start mariadb

设置开机启动
systemctl enable mariadb

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
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‘password‘

完成。

 

2、配置MariaDB的字符集

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

在[client]中添加
default-character-set=utf8
=====================================
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

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                      |
| 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)

字符集配置完成。

 

3、添加用户，设置权限

创建用户命令
mysql>create user [email protected] identified by ‘password‘;

直接创建用户并授权的命令
mysql>grant all on *.* to [email protected] indentified by ‘password‘;

授予外网登陆权限 
mysql>grant all privileges on *.* to [email protected]‘%‘ identified by ‘password‘;

授予权限并且可以授权
mysql>grant all privileges on *.* to [email protected]‘hostname‘ identified by ‘password‘ with grant option;

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。
