腾讯云centos7 搭建mysql环境

1、安装mysql

##添加可以用于安装数据库系统的MySQL存储库 yum localinstall -y https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm##安装 yum install -y mysql-community-server##启动 systemctl start mysqld

---

2、修改root密码

##查看初始密码 grep 'temporary password' /var/log/mysqld.log2017-10-12T02:37:57.483675Z 1 [Note] A temporary password is generated for root@localhost: **6uRg%NmxG9mysql -u root -p 回车输入以上查询的密码登录##关闭密码强度校验set global validate_password_policy=0;set global validate_password_length=1;##修改初始密码ALTER USER 'root'@'localhost' IDENTIFIED BY 'password';##刷新权限FLUSH PRIVILEGES;

---

3、配置远程访问

##备份cp /etc/my.cnf /etc/my.cnf_bk##编辑vi /etc/my.cnf##在最后面加上一行bind-address = 0.0.0.0##重启systemctl restart mysqld

---

4、创建远程访问用户

##创建用户CREATE USER 'husen'@'%' IDENTIFIED BY '123456';##如果创建用户提示密码强度不够，则用第2步中的方法关闭密码强度校验##赋予远程访问权限GRANT ALL PRIVILEGES ON *.* TO 'husen'@'%';##刷新权限FLUSH PRIVILEGES;
