一、安装mysql软件
先检查之前是否有安装过MySQL：
如果有的话，要先卸载：
yum remove mysql mysql-server
卸载干净了！
接着我们来安装。
下载并安装MySQL官方的 Yum Repository,Mysql版本5.7.35
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
下载后直接yum安装
安装MySQL服务器
yum -y install mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql-community-server
[root@localhost ~]# yum -y install mysql-community-server

Resolving Dependencies
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).
The program yum-complete-transaction is found in the yum-utils package.

二、配置Mysql数据库
启动MySQL
systemctl start mysqld.service
查看MySQL运行状态
systemctl status mysqld.service
重启服务：
systemctl restart mysqld.service
停止服务：
systemctl stop mysqld.service
启用服务：
systemctl start mysqld.service找出root初始密码
grep "password" /var/log/mysqld.log 
初始密码为：8bgr,OsWe?;G
登录：
mysql -uroot -p
输入密码（密码是上面查询到的 8bgr,OsWe?;G），此时不能操作数据库，必须修改密码之后才能操作数据库
use mysql;
select host,user,password_expired,password_last_changed,password_lifetime from user;
1.修改密码：
ALTER USER 'root'@'localhost' IDENTIFIED BY 'P17CKSzBp0q2@866';
root 密码就修改为：P17CKSzBp0q2@866
2、实现远程连接
grant all privileges on *.* to root@'%' identified by "P17CKSzBp0q2@866";
执行下面的授权命令，让上面的修改生效。
flush privileges;
接着我们使用工具来进行远程连接：
结果连接不上，是不是没有开启3306端口呢？
开通虚拟机的3306端口，查看虚拟机防火墙的状态，命令如下：
service iptables status
这是因为防火墙没有开启，先重新开启防火墙。
service iptables start 
开启了，重新来连接一下：
看来是3306端口没有启用：
netstat -tunlp
3306端口开启了，看来是需要开启3306端口的防火墙
vim /etc/sysconfig/iptables里面增加：
-A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
保存后，重启防火墙服务！
service iptables restart 
接着再来连接，我们可以看到连接成功了！
使用账号 ： root / P17CKSzBp0q2@866
