# Mysql安装配置卸载

## 1.环境

服务器Centos7

## 2.安装和配置

使用yum安装mysql必须安装mariadb，安装过后不习惯，所以选择手动下载rpm安装。

```bash
# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
# rpm -ivh mysql-community-release-el7-5.noarch.rpm
# yum install mysql-community-server
# service mysqld restart
```

安装后没有设置密码，需要进入命令行界面手动设置一下

```bash
mysql> set password for 'root'@'localhost' =password('password');
Query OK, 0 rows affected (0.00 sec)
```

然后配置远程登陆的权限

```bash
mysql> grant all privileges on *.* to root@'%'identified by 'password' with grant option;flush privileges
mysql> flush privileges;
```

设置配置文件

```bash
vim /etc/my.cnf
[mysql]
default-character-set =utf8
```

## 3.卸载

```bash
yum remove mysql
...
# rpm -qa|grep -i mysql
mysql-community-libs-5.6.34-2.el7.x86_64
mysql-community-release-el7-5.noarch
mysql-community-common-5.6.34-2.el7.x86_64

# yum remove mysql-community-libs.noarch
...
# rpm -qa|grep -i mysql
依此类推
```
