下载mysql源安装包 # wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm 安装mysql源包 #yum localinstall mysql57-community-release-el7-8.noarch.rpm 检查mysql源是否安装成功 # yum repolist enabled | grep "mysql.*-community.*" 看到下图(三个)表示成功: mysql-connectors-community MySQL Connectors Community 36 mysql-tools-community MySQL Tools Community 47 mysql57-community MySQL5.7 Community Server 189 安装MySQL服务 # yum install mysql-community-server 启动MySQL服务 # systemctl start mysqld 查看MySQL的启动状态 # systemctl status mysqld 设置开机启动 # systemctl enable mysqld # systemctl daemon-reload #重新载入 查看root默认密码 # grep ‘temporary password‘ /var/log/mysqld.log 修改root密码 # mysql -uroot -p mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘Abc1234!‘; 或者 mysql> set password for‘root‘@‘localhost‘=password(‘Abc1234!‘); 注意:mysql5.7默认安装了密码安全检查插件(validate_password),默认密码检查策略要求密码必须包含:大小写字母、数字和特殊符号,并且长度不能少于8位。否则会提示ERROR 1819 (HY000): Your passworddoes not satisfy the current policy requirements错误 添加远程连接登录用户,如:用户名:test,密码:Abc@1234 mysql>GRANT ALL PRIVILEGES ON *.* TO ‘test‘@‘%‘IDENTIFIED BY ‘[email protected]‘ WITH GRANT OPTION; 重启mysql服务 # systemctl restart mysqld 完毕,可远程用Navicat连接了。
