centos 6下通过rpm安装mysql5.7

1、下载安装包

wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-common-5.7.28-1.el6.x86_64.rpm wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-libs-5.7.28-1.el6.x86_64.rpm wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-client-5.7.28-1.el6.x86_64.rpm wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-community-server-5.7.28-1.el6.x86_64.rpm

2、执行安装命令

rpm -ivh mysql-community-common-5.7.28-1.el6.x86_64.rpm rpm -ivh mysql-community-libs-5.7.28-1.el6.x86_64.rpm rpm -ivh mysql-community-client-5.7.28-1.el6.x86_64.rpm rpm -ivh mysql-community-server-5.7.28-1.el6.x86_64.rpm

3、初始化与启动服务

# 初始化 mysqld --initialize --user=mysql #启动 service mysqld start

4、查看初始化密码

# 查看初始化密码 more /var/log/mysqld.log

寻找如下语句，其中 g7:Uvjd,>1pL 为初始化密码

A temporary password is generated for root@localhost: g7:Uvjd,>1pL

5、登录与修改密码

mysql -uroot -p

输入密码，登录

6、修改密码

ALTER USER 'root'@'localhost' identified by 'seagle.cn';

修改密码时，注意密码修改规则，有时候要求需要有特殊字符，大小写字母与数组组成
