# Centos下安装mariaDB方法

我在cnaaa上购买了云服务器。

**1、安装mariadb-server**

```
yum install mariadb-server
```

**2、安装相关环境**

```
yum install mariadb-embedded mariadb-libs mariadb-bench mariadb mariadb-sever
```

**3、安装mariadb**

```
yum install mariadb
```

**4、启动mariadb**

```
systemctl start mariadb
```

**5、设置开机启动**

```
systemctl enable mariadb
```

**6、配置数据库**（主要是设置密码）

```
mysql_secure_installation
```

**7、设置编码**

**①在`/etc/my.cnf`文件下添加如下内容：**

```
init_connect='SET collation_connection = utf8_unicode_ci'init_connect='SET NAMES utf8'character-set-server=utf8collation-server=utf8_unicode_ciskip-character-set-client-handshake
```

**②在`/etc/my.cnf.d/client.cnf`文件[client]标签下添加如下内容：**

```
default-character-set=utf8
```

**③在`/etc/my.cnf.d/mysql-clients.cnf`文件[mysql]标签下添加如下内容：**

```
default-character-set=utf8
```

**④重启mariadb，命令如下：**

```
systemctl restart mariadb
```

**⑤查看mariadb查看字符集，语句如下：**

```
show variables like "%character%";show variables like "%collation%";
```

**8、允许远程连接mariadb数据库**

**①关闭防火墙，命令如下：**

```
systemctl stop firewalld
```

**②修改user表中host，具体如下****(依次执行即可)：**

```
select host, user from user;update user set host='%' where host='centos.portal';flush privileges;systemctl restart mariadb
```
