1）下载解压

2）卸载自带的MySQL rpm -qa|grep mariadb　　rpm -e mariadb-libs-5.5.56-2.el7.x86_64 --nodeps 然后启动安装

3）修改MySQL默认的密码设置策略 https://www.cnblogs.com/birdman-oscar/p/9804708.html

set global validate_password_policy=0;

set global validate_password_length=4;

set password for root@localhost = password('root');

 

环境：CentOS7下MySQL5.7

启动 systemctl start mysqld
停止 systemctl stop mysqld
查看 ps -ef | grep mysql

4）授权远程登录

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;

CentOS6 安装MySQL5.7大坑，报

libc.so.6(GLIBC_2.14)(64bit) is needed by mysql-community-libs-5.7.26-1.el7.x86_64错误，网上各种方法尝试解决无效，突然意识到自己一直在CentOS7上安装MySQL，在CentOS6上使用同样的方法肯定不行的，遂百度CentOS6.8安装MySQL5.7发现了一篇文章，自己以前简直浪费时间 https://blog.csdn.net/YHF886/article/details/82190688

 

 

set password for root@localhost = password('fSmJ3y$2Bd!83H2@H');
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'fSmJ3y$2Bd!83H2@H' WITH GRANT OPTION;

 

-- 查看MySQL初始的密码策略
SHOW VARIABLES LIKE 'validate_password%';

-- 设置密码的验证强度等级
set global validate_password_policy=LOW;

-- 设置密码长度
set global validate_password_length=6;
