本文详细介绍了如何在Linux环境下从源安装MySQL数据库，包括下载源安装包、安装MySQL源、安装MySQL服务、启动及设置开机启动，以及如何修改root密码和添加远程登录用户等关键步骤。

下载mysql源安装包
wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
安装mysql源
yum localinstall mysql57-community-release-el7-8.noarch.rpm
检查mysql源是否安装成功
yum repolist enabled | grep “mysql.-community.”

(可选:修改 vim /etc/yum.repos.d/mysql-community.repo源，改变默认安装的mysql版本。比如要安装5.6版本，将5.7源的enabled=1改成enabled=0。然后再将5.6源的enabled=0改成enabled=1即可。)

安装MySQL(如果报错，则运行此命令:yum -y remove mariadb-libs)
yum install mysql-community-server
启动MySQL服务
systemctl start mysqld
开机启动
systemctl enable mysqld
systemctl daemon-reload
修改root本地登录密码
1）查看mysql密码
shell> grep ‘temporary password’ /var/log/mysqld.log
2）连接mysql
mysql -uroot -p
3）修改密码[注意：后面的分号一定要跟上]
ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘MyNewPass4!’;
或者：
set password for ‘root’@‘localhost’=password(‘MyNewPass4!’);
show variables like ‘%password%’;
添加远程登录用户
mysql> GRANT ALL PRIVILEGES ON . TO ‘root’@’%’ IDENTIFIED BY ‘XqSadmin9527008@’ WITH GRANT OPTION;
