mysql通过文档读取并执行命令–快速为mysql添加多用户和数据库

# vi mysqlusers.txt

create database dataname;
grant all privileges on dataname.* to username@localhost identified by ‘password‘;
flush privileges;

# /usr/local/mysql/bin/mysql -u root -p password < mysqlusers.txt

　　　蓝色斜体部分为对应的用户名和密码，添加多个用户及数据库，只需要复制中间部分代码并修改对应的位置即可，如：
　　　create database dataname1;
　　　grant all privileges on dataname1.* to username1>@localhost" identified by ‘password‘;
　　　flush privileges;

　　　create database dataname2;
　　　grant all privileges on dataname2.* to username2>@localhost" identified by ‘password‘;
　　　flush privileges;
