服务器装置MySQL

服务器应用CentOS7

数据库装置

  1. 查看是否有装置MySQL

    yum list installed | grep mysql

  2. 下载MySQL安装包，这里下载的是8.0

    wget https://dev.mysql.com/get/mysql80-community-release-el7-2.noarch.rpm

  3. 应用yum装置rpm包

    yum -y install mysql80-community-release-el7-2.noarch.rpm

  4. 装置MySQL服务，过程比较慢，须要下载

    yum -y install mysql-community-server

MySQL配置

  1. 启动MySQL服务，记得是mysqld

    systemctl start mysqld.service

  2. 查看MySQL运行状态

    systemctl status mysqld.service● mysqld.service - MySQL Server   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)   Active: active (running) since 三 2021-07-28 16:44:56 CST; 1min 26s ago     Docs: man:mysqld(8)           http://dev.mysql.com/doc/refman/en/using-systemd.html  Process: 17913 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited, status=0/SUCCESS) Main PID: 18001 (mysqld)   Status: "Server is operational"   CGroup: /system.slice/mysqld.service           └─18001 /usr/sbin/mysqld7月 28 16:44:47 VM-12-5-centos systemd[1]: Starting MySQL Server...7月 28 16:44:56 VM-12-5-centos systemd[1]: Started MySQL Server.

  3. 重启/进行服务

    service mysqld restart                  #重新启动Mysqlsystemctl stop mysqld.service   #进行Mysql

  4. 查看MySQL的root用户初始密码

    grep "password" /var/log/mysqld.log2021-07-28T08:44:50.767029Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: r!FYj6ujDhx%

  5. 登录root用户

    mysql -u root -p

  6. 批改root明码

    # 能够先设置容许简略明码set global validate_password.policy=0;set global validate_password.length=4;# 批改明码ALTER USER 'root'@'localhost' IDENTIFIED BY '你的明码';

  7. 敞开yum自动更新

    yum -y remove mysql80-community-release-el7-2.noarch

至此MySQL曾经装置实现

客户端近程操作数据库

  1. 查看是否开启了3306端口

    我的服务器是腾讯云，所以在控制台配置端口就行了，如果不是能够自行百度

  2. MySQL设置容许近程登录

    USE mysql;UPDATE USER SET host = '%' WHERE USER = 'root';FLUSH PRIVILEGES;
  3. 而后应用客户端登录即可
