解压压缩包

tar -xvf mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar

有些linux版本可能会自带mariadb，需要先删掉

rpm -e mariadb-libs-5.5.56-2.el7.x86_64 --nodeps

安装mysql

rpm -ivh mysql-community-common-5.7.28-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.28-1.el7.x86_64.rpm 
rpm -ivh mysql-community-libs-compat-5.7.28-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.28-1.el7.x86_64.rpm
#这一步可能安装不上需要插件，先安装插件： 
# yum install libaio  
rpm -ivh mysql-community-server-5.7.28-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-5.7.28-1.el7.x86_64.rpm

#初始化mysql，会生成mysql密码
mysqld --initialize --user=mysql

#查看下生成的mysql密码
cat /var/log/mysqld.log

#注册为自启动服务并启动
systemctl start mysqld.service

systemctl status mysqld.service

mysql -uroot -p输入临时密码

#修改密码 并且授权远程访问

use mysql;
grant all on *.* to root@localhost identified by 'root';

flush privileges;

#关闭防火墙一些东西，以免不能远程访问
