Can not open,/var/log/cassandra/gc.log due to Permission denied

  • 772

What do /var/log files serve for?When I try to run cassandra on my Ubuntu 16.04

OpenJDK 64-Bit Server VM warning: Cannot open file /var/log/cassandra/gc.log due to Permission denied

Later

19:47:58,887 |-INFO in ch.qos.logback.core.rolling.RollingFileAppender[SYSTEMLOG] - Active log file name: /var/log/cassandra/system.log
19:47:58,887 |-INFO in ch.qos.logback.core.rolling.RollingFileAppender[SYSTEMLOG] - File property is set to [/var/log/cassandra/system.log]
19:47:58,889 |-ERROR in ch.qos.logback.core.rolling.RollingFileAppender[SYSTEMLOG] - openFile(/var/log/cassandra/system.log,true) call failed. java.io.FileNotFoundException: /var/log/cassandra/system.log (Permission denied)
    at java.io.FileNotFoundException: /var/log/cassandra/system.log (Permission denied)

Why do I have these problems? This is my java

java -version
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.16.04.2-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

These are the permissions 

/var/log$ ls -la cassandra/
total 300
drwxr-xr-x  2 cassandra cassandra   4096 jan.  25 15:50 .
drwxrwxr-x 14 root      syslog      4096 jan.  25 15:49 ..

    I was facing the same issue, fixed using following commands:

    sudo chown -R $USER:$GROUP /var/lib/cassandra/

    sudo chown -R $USER:$GROUP /var/log/cassandra/
