篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了阿里云ECS下基于Centos7.4安装MySQL5.7.20相关的知识，希望对你有一定的参考价值。
1、首先登录阿里云ECS服务器，如下图所示：
2、卸载MariaDB
说明：CentOS7.x默认安装MariaDB而不是mysql，而且yum服务器上也移除了MySQL相关的软件包。因为MariaDB和MySQL可能会冲突，故先卸载MariaDB!
3、到mysql的官网下载最新版mysql的rpm集合包。
URL如下：https://downloads.mysql.com/archives/community/
4、进入/usr/local/src目录，使用lrzsz中的rz工具进行上传。
或者直接使用linux 下的wget工具进行下载：wget https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar（如果没有wget工具，使用yum install -y wget进行安装）
5、上传mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar到Linux服务器，并解压tar包。
6、使用rpm -ivh命令进行安装。
安装过程中缺少依赖包libaio，使用 yum install -y libaio 进行安装。
再次使用rpm -ivh 安装
6、上面几个包有依赖关系，执行有先后顺序。
使用rpm安装方式安装mysql，安装的路径如下：
a. 数据库目录
/var/lib/mysql/
b. 配置文件
/usr/share/mysql(mysql.server命令及配置文件)
c. 相关命令
/usr/bin(mysqladmin mysqldump等命令)
d. 启动脚本
/etc/rc.d/init.d/(启动脚本文件mysql的目录)
e. /etc/my.conf(mysql数据库配置文件)
