CentOS7.3(64位)安装MySQL5.7

Centos下安装MySQL比较麻烦,每一步都有坑,还是记下来比较好 O(∩_∩)O哈哈~

1. 下载安装包

官网下载文件

  • 选择系统版本

下载

  • 勾选如下选项下载:

勾选


2. 上传服务器并解压

注: CentOS7预装MariaDB,可能有冲突,先卸载


$ rpm -qa |grep -i mariadb  

$ rpm -e --nodeps mariadb-libs-5.5.52-1.el7.x86_64`

再执行解压:

$ tar -xvf mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar

解压


3. 开始安装

执行以下命令:


$ rpm -ivh mysql-community-common-5.7.19-1.el7.x86_64.rpm

$ rpm -ivh mysql-community-libs-5.7.19-1.el7.x86_64.rpm

$ rpm -ivh mysql-community-libs-compat-5.7.19-1.el7.x86_64.rpm 

$ rpm -ivh mysql-community-client-5.7.19-1.el7.x86_64.rpm

$ rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm

$ rpm -ivh mysql-community-devel-5.7.19-1.el7.x86_64.rpm

倒数第二步可能会报如下错误

错误

原因:缺少libaio库

解决方案:安装libaio库 点我


$ rpm -ivh libaio-0.3.107-10.el6.x86_64.rpm

4. 启动mysql服务并设置开机启动


systemctl start mysqld

systemctl enable mysqld

systemctl daemon-reload

5. 根据临时密码登录MySQL

$ vi /var/log/mysqld.log

密码


6. 修改密码

登录后必须修改密码,不然无法执行sql语句,会报如下错误:

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

当执行

ALTER USER 'root'@'localhost' IDENTIFIED BY 'wang123';

修改密码时又会报一下错误:

ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

这个错误与validate_password_policy密码策略有关

执行以下代码修改策略,此时只会基于长度判断:

$ set global validate_password_policy=0;

**太复杂了,
