MySQL 如何快速复制用户权限到其他环境

脚本用途：

 1、mysql主从搭建，从库用户权限的复制（可直接在主库执行脚本，将输出结果在从库执行）

 2、实现 pt-show-grants【打印权限信息】（线上可选择不用安装pt软件..通过脚本实现pt-show-grants功能）

 3、用户权限统计

<b>脚本：</b>

hostname=192.168.1.12

username=lottery

password=lottery

touch create_user.txt

for port in `ps -ef | grep mysql| grep socket| grep datadir| awk -f= '{print $nf}'`

  do

   sock=`ps -ef | grep mysql| grep socket| grep datadir|awk -f".pid" '{print $nf}'| grep $port`

   echo "-------"$port"-create_user.sql:-------" &gt;&gt;create_user.txt

     echo "select concat('show grants for ''',user,'''@''',host, ''';') from mysql.user where user &lt;&gt;'root' and user &lt;&gt;'' " | \

     mysql --host=$hostname --user=$username --password=$password $sock -n | \

     sed "s/$/;/"  &gt;&gt;create_user.txt

done

cat create_user.txt

rm -rf create_user.txt

<b>脚本打印信息如下：</b>

<b>pt-show-grants 打印权限介绍</b>

l 功能介绍：

规范化和打印 mysql权限，让你在复制、比较 mysql权限以及进行版本控制的时候更有效率！

l 用法介绍：

pt-show-grants [option...] [dsn] 选项自行用help 查看，dsn 选项也请查看help，选项区分大小写。

l 使用示例：

查看指定mysql的所有用户权限： pt-show-grants --host='localhost' --user='root' --password='zhang@123' 

查看执行数据库的权限： pt-show-grants --host='localhost' --user='root' --password='zhang@123' --database='hostsops' 

查看每个用户权限生成 revoke收回权限的语句： pt-show-grants --host='localhost' --user='root' --password='zhang@123' --revoke
