Centos7在线安装MySQL5.6

1.rpm下载mysql包

wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

2.安装mysql和mysql服务

    rpm -ivh mysql-community-release-el7-5.noarch.rpm

    yum -y install mysql-server

3.检查是否安装成功

#启动MySQL

systemctl start mysqld

#查看MySQL状态

systemctl status mysqld

#出现绿色的Active：active（running）

4.给root用户添加密码

        mysqladmin -u root password "111111"

5.登录MySQL

        mysql -u root -p

6.远程登陆mysql

需要给mysql的root用户添加权限，这里需要在mysql的界面内输入

    grant all privileges on *.* to 'root'@'%' identified by '111111' with grant option;

7.mysql远程登录使用的是3306端口，所以防火墙也要开启相应的端口

[root@localhost ~]# firewall-cmd --add-port=3306/tcp --permanent
success
[root@localhost ~]# systemctl restart firewalld
[root@localhost ~]# firewall-cmd --list-all
public (active)

记住修改下时区

#查看时区

timedatectl

#修改时区+8

timedatectl set-timezone Asia/Shanghai
