1.下载安装文件

网址：MySQL

2.上传到CentOS7上

创建文件夹

[root@localhost ~]# cd /opt/
[root@localhost opt]# mkdir software

上传文件

3.解压MySQL文件

[root@localhost software]# tar -xvf mysql-5.7.38-1.el7.x86_64.rpm-bundle.tar

4.清理系统中残留的MySQL

查找残留文件

[root@localhost software]# rpm -qa| grep -i mariadb
[root@localhost software]# rpm -qa| grep -i mysql
[root@localhost software]# find / -name mysql

删除残留文件

[root@localhost software]# rpm -e --nodeps mariadb-libs-5.5.56-2.el7.x86_64
[root@localhost software]# rm -rf /etc/selinux/targeted/active/modules/100/mysql
[root@localhost software]# rm -rf /usr/lib64/mysql

5.安装MySQL

[root@localhost software]# rpm -ivh mysql-community-common-5.7.38-1.el7.x86_64.rpm
[root@localhost software]# rpm -ivh mysql-community-libs-5.7.38-1.el7.x86_64.rpm
[root@localhost software]# rpm -ivh mysql-community-client-5.7.38-1.el7.x86_64.rpm
[root@localhost software]# rpm -ivh mysql-community-server-5.7.38-1.el7.x86_64.rpm

如果你在最后一个遇到问题，记得安装 net-tools

[root@localhost software]# yum install net-tools

6.启动MySQL 并设置开机自启动

[root@localhost software]# systemctl start mysqld
[root@localhost software]# systemctl enable mysqld
[root@localhost software]# systemctl status mysqld

7.查找临时密码，并修改密码

[root@localhost software]# cat /var/log/mysqld.log | grep password
[root@localhost software]# mysql -uroot -p
mysql> set password = password("Aa@12345678")-> ;
Query OK, 0 rows affected, 1 warning (0.00 sec)mysql> exit;
