如何远程清理Production上48组MySQL DB Server上面的过期失效的备份

如何远程清理48组MySQL DB Server上面的过期实效的备份! 刚开始想到一个个从control控制机器ssh进去，rm 掉，然后exit，再通过control机器ssh进去，再rm再exit，这样的话岂不是要操作48次ssh以及exit，48台还能接受，如果是480台，4800台呢，any way ？

OK，我想到了，写一个shell脚本，在control机器上面远程执行ssh命令，不需要ssh进具体的单台db了，如下clean.sh

ssh aaaaaaaaa048xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa047xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa045xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa044xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa043xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa042xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa041xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa023xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa022xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa021xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa020xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa019xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa018xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa017xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa016xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa015xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa014xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa013xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa012xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa011xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa010xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa009xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa008xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa007xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa006xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa003xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa002xxxxxx "sudo -u mysql du -sh /mysqlback/*";

ssh aaaaaaaaa001xxxxxx "sudo -u mysql du -sh /mysqlback/*";

PS：

1 ssh aaaaaaaaa001xxxxxx "sudo -u mysql du -sh /mysqlback/*";这个指示最后check检查备份有没有被删除的脚本你可以将du -sh /mysqlback/*";换成rm -rf就变成了自己要清理文件的功能了。

2 我这里ssh是不带密码的，如果你的ssh还要带输入密码验证的话，请试下：ssh pass -p 'password' sshroot@xx.com "command"命令

run 这个clean脚本， 我这里ssh 进aaaaaaaaa001xxxxxx 是不需要密码的，而且因为进去db server还需要切换到mysql帐号，否则不能rm操作mysql用户组的文件。远程命令里面用了sudo -u mysql前缀。
