Running tomcat under tomcat service account in CentOS

Question

I aspire to create a text chatting website with some extra features. As for the core text chatting part, is python an appropriate language for such a kind ? If so, is their any libraries which help in this process.

I would also require real time data being pushed back to the browser, implying i would be using the web-sockets also. Is tornado the appropriate choice of server ? I am a newbie in terms of network based application or website.

Solution

If you are not logged in/elevated as root, and are a "regular" user, you will need to provide the password for another user account.

However, you may want to look into sudo to achieve what you are trying accomplish. You will likely need to consult with your sysadmin to properly set you up in the sudoers file in order to grant you the access you require.

I'm sorry, but I think your question is too vague and overly broad to be answered here on SO; see the FAQ. If you have more concrete problems (preferably involving some code), feel free to ask those!

I was looking for an answer with supported libraries or examples of projects.

My user account is granted sudo rights but when I use sudo to run the startup script I get the message: "This account is currently not available."

That's normally due to a lack of a shell specified for the user account. Sometimes sysadmins do that for security purposes.

I wasn't actually trying to login to this account...just trying to run commands as this user which I should be able to do.

@Tom - you can run commands as a user via sudo as well: sudo -u tomcat <cmd>.
