How to fix incorrect permissions when installing Tomcat?

I've just installed Tomcat 7 in Ubuntu 13.04 but i have a problem in starting the server.

I've installed Tomcat 7 by the command:

tar -xzpf ./apache-tomcat-7.0.26.tar.gz -C /chemin_vers_dossier_d_installation/

and to start the server :

 /opt/apache-tomcat-7.0.39/bin/catalina.sh run

but i had this error message: 

run

Using CATALINA_HOME:   /opt/apache-tomcat-7.0.39
Using CATALINA_TMPDIR: /opt/apache-tomcat-7.0.39/temp
Using JRE_HOME:        /home/fakarovic/jdk1.6.0_45/

Follow the below steps for Windows users

  • Right-click on the Tomcat directory and choose properties
  • Under Security tab, make sure the user permissions are assigned with full-control
  • Click on Advanced button.
  • In the Advanced Security Settings pop-up, click on Add button and add user by selecting the principal

An option is the following :

sudo chgrp -R <user> <directory_server.xml>

For example :

sudo chgrp -R tomcat /opt/apache-tomcat-7.0.39

Where :

  • chgrp -R is the assignment of permits
  • tomcat is the user
  • /opt/tomcat is the directory where is it server.xml

Tomcat has strengthened the security requirements at file system level, that's why if you are upgrading from an earlier version, you will have this problem.

From: https://tomcat.apache.org/tomcat-7.0-doc/security-howto.html

File permissions should also be suitably restricted. Taking the Tomcat instances at the ASF as an example (where auto-deployment is disabled and web applications are deployed as exploded directories), the standard configuration is to have all Tomcat files owned by root with group Tomcat and whilst owner has read/write privileges, group only has read and world has no permissions.

Means you have to restrict the others access permissions to tomcat's directories. Specially $TOMCAT_HOME/conf. That's why you are getting the error, because there's more access that minimum required for Tomcat to start.

Long story short, restrict Tomcat directory access to only the user running the process.

The exceptions are the logs, temp and work directory that are owned by the Tomcat user rather than root.

Its a problem related to file permissions in linux. Check your file permission of tomcat installation directory, change it then it will work.

Becauase see this line of the log

May 10, 2013 9:19:32 AM org.apache.catalina.startup.Catalina load
WARNING: Permissions incorrect, read permission is not allowed on the file.

The excpetion is itself shouting that I have a file permission problem.
