Permissions user

在对MySQL数据库进行迁移的时候,有时候也需要迁移源数据库内的用户与权限。对于这个迁移我们可以从mysql.user表来获取用户的相关权限来生成相应的SQL语句,然后在目标服务器上来执行生成的SQL语句即可。本文提供了生成提取用户权限的脚本并给出演示。

1、生成用户权限的脚本

[root@HKBO ~]# more exp_grant.sh
#!/bin/bash
#Function export user privileges

pwd=123456
expgrants()
{
  mysql -B -u'root' -p${pwd} -N $@ -e "SELECT CONCAT(
    'SHOW GRANTS FOR ''', user, '''@''', host, ''';'
    ) AS query FROM mysql.user" | \
  mysql -u'root' -p${pwd} $@ | \
  sed 's/\(GRANT .*\)/\1;/;s/^\(Grants for .*\)/-- \1 /;/--/{x;p;x;}'
}
expgrants > ./grants.sql
Copy after login

2、生成权限SQL脚本

[root@HKBO ~]# ./exp_grant.sh 

[root@HKBO ~]# head grants.sql
-- Grants for root@127.0.0.1 
GRANT ALL PRIVILEGES ON *.* TO 'root'@'127.0.0.1' IDENTIFIED BY PASSWORD '*EB3EA446C759C9DA93F84FCB56430DBEF051A9DD' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON `CNBO0815`.* TO 'root'@'127.0.0.1' WITH GRANT OPTION;

-- Grants for root@172.16.10.% 
GRANT ALL PRIVILEGES ON *.* TO 'root'@'172.16.10.%' IDENTIFIED BY PASSWORD '*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9';

-- Grants for CNBO@192.168.1.% 
GRANT USAGE ON *.* TO 'CNBO'@'192.168.1.%' IDENTIFIED BY PASSWORD '*ABD91BAD4A3448428563952E281015B237310EA8';
         ...........................

3、在目标服务器上执行脚本
将生成的脚本在目标服务器上执行即可。 mysql -uname -ppwd 需要注意:
a、目标服务上为非空服务器,已经存在一些账户及权限应考虑会覆盖的问题。
b、如果仅仅需要迁移非root用户,可以在原脚本中添加过滤条件,即 where user'root' 。
