I have an application utilizing Log4j2 using a rolling file appender. Within each appender, I set the log file permissions using the new "filePermissions" attribute to be 644 (rw-r-
r-). If I run my application as "root", then try to run as any other user, I receive an error with the text (Note: ... == "org.apache.log4j.core."):
ERROR RollingFileManager (/var/log/myApp/Info.log) java.io.FileNotFoundException: /var/log/myApp/Info.log (Permission denied) java.io.FileNotFoundException: var/log.myApp/Info.log (Permission denied)
at java.io.FileOutputStream.open0 (Native Method)
My configuration file is like the following:
I have verified that the permissions on "/var/log/myApp" are 777 (rwxrwxrwx). I have also verified that as a non-root user, I am able to move an existing log file (e.g., "mv Info.log Info_Archive.log" works when running as non-root user, even though running my application as that user results in the aforementioned error). My expectation is that the file would be moved, a new file created, then the output stream opened. However, it appears from the error that the output stream is opened, then the log file renamed, and finally a new log file created and opened. A work-around for this issue is to create log files with 777 permissions, but I don't want to give all users full permission to my log files.
