CentOS 7.0 使用 yum 安装 MariaDB 与 MariaDB 的简单配置

Posted 2020-10-21

1、安装MariaDB

安装命令

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

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 -ppassword
完成。

2、配置MariaDB的字符集

文件/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
文件/etc/my.cnf.d/client.cnf

vi /etc/my.cnf.d/client.cnf
在[client]中添加

default-character-set=utf8
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
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

+--------------------------+----------------------------+
| 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。
