软链接ln -s以及如何解决其产生“Too many levels of symbolic links ”的错误？

2017-03-06 11:00 489 查看

[hadoop@hddcluster2 script]$ ls /etc/init.d/hadoop.sh
ls: cannot access /etc/init.d/hadoop.sh: Too many levels of symbolic links
[hadoop@hddcluster2 script]$ ls /home/hadoop/script/hadoop.sh  /etc/init.d/hadoop.sh
ls: cannot access /etc/init.d/hadoop.sh: Too many levels of symbolic links
/home/hadoop/script/hadoop.sh

解决办法：sudo 删除链接，然后补上全路径。
在做ln的时候要将文件的绝对路径下的完整目录写上去！例子如下：

[hadoop@hddcluster2 script]$ sudo rm /etc/init.d/hadoop.sh
[hadoop@hddcluster2 script]$ sudo ln -s  /home/hadoop/script/hadoop.sh  /etc/init.d/hadoop.sh
[hadoop@hddcluster2 script]$ /etc/init.d/hadoop.sh st
/etc/init.d/hadoop.sh {start|stop|restart|status}
[hadoop@hddcluster2 script]$ /etc/init.d/hadoop.sh status
11283 ResourceManager
12323 Jps
10836 DataNode
10694 NameNode
11033 SecondaryNameNode
11610 NodeManager
11756 JobHistoryServer
