mysql5.7 版本

CentOS 7.5系统安装使用Mysql 5.7数据库-阿里云开发者社区，其中需要补充以下两点：

1）如果安装mysql的时候报错Failing package is: mysql-community-client-5.7.40-1.el7.x86_64 GPG Keys are configured as，密钥过期，要按以下方法：

rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022

2）查询初始密码的时候如下：

复制代码

[root@VM-2-185-centos bin]# grep 'temporary password'  /var/log/mysqld.log
2023-12-05T05:45:29.627475Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: hTTS#V__H3xt

修改系统密码，授权一个账户远程访问。

复制代码

mysql> alter user root@"localhost" identified by 'Fan.88888';
