mysql新建权限受控制的用户：支持正常增删改查及文件导出命令mysqldump

代码如下：

CREATE USER 'xxxx'@'localhost' IDENTIFIED BY '账户链接密码';
GRANT SELECT, INSERT, UPDATE, DELETE, ALTER, CREATE, RELOAD, DROP, INDEX, LOCK TABLES, REFERENCES ON 数据库名.* TO 'xxxx'@'localhost';

CREATE USER 'xxxx'@'192.168.0.%' IDENTIFIED BY '账户链接密码';
GRANT SELECT, INSERT, UPDATE, DELETE, ALTER, CREATE, RELOAD, DROP, INDEX, LOCK TABLES, REFERENCES ON 数据库名.* TO 'xxxx'@'192.168.0.%';

CREATE USER 'xxxx'@'%' IDENTIFIED BY '账户链接密码';
GRANT SELECT, INSERT, UPDATE, DELETE, ALTER, CREATE, RELOAD, DROP, INDEX, LOCK TABLES, REFERENCES ON 数据库名.* TO 'xxxx'@'%';

CREATE USER 'xxxx'@'127.0.0.1' IDENTIFIED BY '账户链接密码';
GRANT SELECT, INSERT, UPDATE, DELETE, ALTER, CREATE, RELOAD, DROP, INDEX, LOCK TABLES, REFERENCES ON 数据库名.* TO 'xxxx'@'127.0.0.1';
FLUSH PRIVILEGES;
