mysql的安装

安装步骤

1、下载 MySQL Yum Repository

wget http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm

2、添加 MySQL Yum Repository

yum -y install mysql57-community-release-el7-10.noarch.rpm

3、安装mysql社区版

yum -y install mysql-community-server

注意：这一步需要下载190M左右的文件

4、查看mysql服务状态

service mysqld status

5、启动mysql服务

service mysqld start

6、查看mysql服务状态

service mysqld status

7、查看root初始密码

grep “password” /var/log/mysqld.log

8、登录mysql

mysql -uroot -p

9、输入命名

show databases;

显示：You must reset your password using ALTER USER statement before executing this statement.

需要重置密码

10、修改root密码

ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘new password’;

密码注意有大小写，例如： Wang!123456

以可以使用以下语句修改密码，效果是一样的：

set password for ‘root’@‘localhost’ = password(‘Li!123456’);

flush privileges;

11、添加新用户

grant all privileges on . to ‘lcx’@’%’ identified by ‘Wang!123456’ with grant option;

火墙打开3306端口

firewall-cmd --zone=public --add-port=3306/tcp --permanent

注意：RPM是Red-Hat Package Manager（RPM软件包管理器）的缩写
