阿里云centos7安装mysql 5.7.29

1.下载，进入mysql官网，查找需要的版本；

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-community-server-5.7.29-1.el7.x86_64.rpm

2.安装mysql包

rpm -ivh mysql-community-server-5.7.29-1.el7.x86_64.rpm

报如下图错误，提示依赖mysql-community-client，mysql-community-common-5.7.29

 wget下载这些包，rpm -ivh *.rpm （安装rpm包） #RPM软件包管理器，-i 安装rpm包，-vh显示安装进度；最终发现需要安装这4个；

 

 3.开启mysql服务

systemctl start mysqld.service

查看mysql状态：systemctl status mysqld.service

 4.查看mysql临时密码,grep "password" /var/log/mysqld.log;

　　修改密码：ALTER USER 'root'@'localhost' IDENTIFIED BY 'P@ssw0rd';
