Cause

/usr/local/avamar/var/mc/server_data/prefs/preferences.dtd 檔案的許可權不正確。

觀察到的許可權 
admin@ave197:~/>: ls -la /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd
-r-------- 1 admin admin 4506 Feb  3  2022 /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd

預期的許可權 
admin@ave197:~/>: ls -la /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd
-r--r--r-- 1 admin admin 4506 Feb  3  2022 /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd

Resolution

請依照以下指示解決問題。

更正許可權： 
chmod 444 /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd
現在請檢閱檔案，檔案應該會顯示正確的許可權。 
r--r--r-- 1 admin admin 4.5K /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd
重新開機 tomcat （以 root 身分）：
