Mysql服务器搭建

Posted 2020-12-13 松晨

1：安装从网上下载文件的wget命令
[root@master ~]# yum -y install wget

2：下载mysql的repo源
[root@master ~]# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

3：安装mysql-community-release-el7-5.noarch.rpm包
[root@master ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm

4：查看下
[root@master ~]# ls -1 /etc/yum.repos.d/mysql-community* /etc/yum.repos.d/mysql-community.repo /etc/yum.repos.d/mysql-community-source.repo
会获得两个mysql的yum repo源：/etc/yum.repos.d/mysql-community.repo，/etc/yum.repos.d/mysql-community-source.repo。

5：安装mysql
[root@master ~]# yum install mysql-server

6：安装完成之后，启动MySql服务
[root@master ~]# systemctl start mysql.service

7：为mysql的root帐户设置密码
[root@master ~]# mysql_secure_installation
回车，根据提示输入Y
输入2次密码，回车
根据提示一路输入Y
最后出现：Thanks for using MySQL!
MySql密码设置完成，重新启动 MySQL

 

 

8：重启
[root@master ~]# systemctl restart mysqld

9：为Mysqls配置远程登录
1)在本机先使用root用户登录mysql
mysql -u root -p"123456"
2)进行授权操作：
mysql>GRANT ALL PRIVILEGES ON *.* TO \'root\'@\'%\' IDENTIFIED BY \'123456\' WITH GRANT OPTION;

3)重载授权表
FLUSH PRIVILEGES;

到此可以通过navicat连接mysql
(注意：如果连接不上，要关闭防火墙：systemctl disable firewalld.service)
