linux mysql 白名单_Linux-部署mysql

1. 下载 mysql 安装包

这一步本人是在window下载，通过ftp 传送到Linux root目录下  (https://www.cnblogs.com/yimihua-kai/p/11663192.html)

2. 安装mysql源

yum localinstall mysql57-community-release-el7-8.noarch.rpm

3．检查mysql源是否安装成功

yum repolist enabled | grep "mysql.*-community.*"

4. 安装

yum install mysql-community-server

5. 启动

systemctl start mysqld

6. 获取临时登录密码

grep 'temporary password' /var/log/mysqld.lo

7. 用临时登录密码登录mysql

mysql –u root –p

Password:填写临时登录密码

8. 修改密码

set password =password(‘123456’)

出现问题：ERROR 1819 (HY000): Your password does NOT satisfy the CURRENT policy requirements。

解决方案：密码长度限制问题

set global validate_password_policy=0  (修改validate_password_policy参数的值)

set global validate_password_length=1  (validate_password_length(密码长度))

再次修
