这回安装数据库装，做下记录。
1、下载mysql源安装包
shell> wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
2、安装mysql源
shell> yum localinstall mysql57-community-release-el7-8.noarch.rpm
3、检查mysql源是否安装成功
shell> yum repolist enabled | grep "mysql.*-community.*"
4、安装MYSQL
shell> yum install mysql-community-server
5、启动MYSQL服务
shell> systemctl start mysqld
6、设置开机启动
shell> systemctl enable mysqld
shell> systemctl daemon-reload
7、查看MYSQL临时密码
shell> grep ‘temporary password‘ /var/log/mysqld.log
8、修改MYSQL默认密码
shell> mysql -uroot -p mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘MyNewPass4!‘; 或 mysql> set password for ‘root‘@‘localhost‘=password(‘MyNewPass4!‘);
9、添加远程登陆用户
mysql> GRANT ALL PRIVILEGES ON *.* TO ‘yangxin‘@‘%‘ IDENTIFIED BY ‘Yangxin0917!‘ WITH GRANT OPTION;
10、配置默认编码为UTF-8
[mysqld] character_set_server=utf8 init_connect=‘SET NAMES utf8‘
11、开启防火墙
firewall-cmd --add-port=3306/tcp --permanent
之前MYSQL配置好了，但是无法远程登陆，发现系统中没有IPtable。其实CentOS7 中是firewall,需要上面的命令才能开启MYSQL 3306端口。
