一、安装Mysql数据库

1、安装依赖及Mysql数据库

# 安装yum-utils工具
[root@localhost ~] yum install yum-utils

# 添加MySQL官方的Yum仓库
[root@localhost home] rpm -Uvh https://dev.mysql.com/get/mysql84-community-release-el7-1.noarch.rpm 

# 添加Mysql官方的Yum仓库（提前下载好的rpm包，直接执行）
[root@localhost ~] rpm -ivh ./mysql84-community-release-el7-1.noarch.rpm 

# 安装Mysql数据库
[root@localhost home] yum install mysql-community-server

# 启动Mysql数据库
[root@localhost home] systemctl start mysqld

# 检查Mysql数据库启动状态
[root@localhost home] systemctl status mysqld

2、设置数据库密码

# 查看Mysql临时密码（下方1foO5_gwDktt为临时密码）
[root@localhost home] cat /var/log/mysqld.log | grep password
2024-06-09T04:37:47.967571Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: 1foO5_gwDktt

# 使用临时密码登陆数据库
[root@localhost home] mysql -uroot -p'1foO5_gwDktt' -hlocalhost

# 修改Mysql数据库密码（Mysql8不支持简易密码，此处将密码设置为“Mysql123_”）
