Linux服务器MySQL安装

Linux服务器MySQL安装

1. MySQL官网下载如图：

2. 安装MySQL

   [root@iZ2zebb0428roermd00462Z /]# rpm -ivh https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch

   过滤MySQL：

   [root@iZ2zebb0428roermd00462Z /]#yum repolist all |grep mysql

  enabled是已经开启的，现在安装mysql57-community，把disabled设置为enabled

   看看都装了什么：[root@iZ2zebb0428roermd00462Z /]#rpm -ql mysql80-community-release

   安装

   查看manager: [root@iZ2zebb0428roermd00462Z /]#yum provides yum-config-manager

     mysql80-community禁止：[root@iZ2zebb0428roermd00462Z /]# yum-config-manager --disable mysql80-community

     mysql57-community开启：[root@iZ2zebb0428roermd00462Z /]# yum-config-manager --enable mysql57-community

    查看结果：

     [root@iZ2zebb0428roermd00462Z /]# yum repolist all |grep community/x86_64

    安装MySQL：

   [root@iZ2zebb0428roermd00462Z /]# yum install mysql-community-server -y

  2. 启动： [root@iZ2zebb0428roermd00462Z /]# systemctl start mysqld

  3.要马上修改密码，首先查找默认的密码：

   [root@iZ2zebb0428roermd00462Z /]# grep "password" /var/log/mysqld.log

  4. 进入mysql：

   [root@iZ2zebb0428roermd00462Z /]#  mysql -uroot -p"lpdIi.82Dxky"

  5. 修改密码：

    [root@iZ2zebb0428roermd00462Z /]# alter user root@‘localhost‘ identified by ‘新密码‘;

   密码不要太简单，不然会出现下面错误：

  6. 授权：

   [root@iZ2zebb0428roermd00462Z /]# grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘Bgx123.com‘;

   [root@iZ2zebb0428roermd00462Z /]# flush privileges; 

  7. 启动mysql

    [root@iZ2zebb0428roermd00462Z /]#  systemctl start mysqld

    [root@iZ2zebb0428roermd00462Z /]# service mysqld restart 

 8. navicat 连接mysql：

   一定要关闭防火墙：[root@iZ2zebb0428roermd00462Z /]# systemctl stop firewalld.service

   还要注意阿里云服务器对mysql端口开放
