由於我手賤，想要重啟一下ranger admin，但是出現了如下的bug

[root@hadoop102 bin]# sudo -i -u ranger ranger-admin start
-bash: /bin/ranger-admin: Permission denied
[root@hadoop102 bin]# chmod 777 ranger-admin 
[root@hadoop102 bin]# sudo -i -u ranger ranger-admin start
Starting Apache Ranger Admin Service
/bin/ranger-admin: line 88: /opt/module/ranger/ranger-2.0.0-admin/ews/logs/catalina.out: Permission denied
Apache Ranger Admin Service failed to start!
[root@hadoop102 bin]# sudo -i -u ranger ranger-admin stop
Apache Ranger Admin Service is not running
[root@hadoop102 bin]# sudo -i -u ranger ranger-admin start
Starting Apache Ranger Admin Service
/bin/ranger-admin: line 88: /opt/module/ranger/ranger-2.0.0-admin/ews/logs/catalina.out: Permission denied
Apache Ranger Admin Service failed to start!
[root@hadoop102 bin]# cd /opt/module/ranger/
[root@hadoop102 ranger]# ll

把catalina.out刪除也不行，把logs刪除也不行

後面的解決方案是重新執行.setup.sh命令即可

[root@hadoop102 ranger-2.0.0-admin]# ./setup.sh
