SEVERE: Cannot start server. Server instance is not configured.

What could be the possible error? In my server configuration I am using "Use Tomcat installation". I had to replace the server.xml, context.xml, portal-ext.properties, catalina.xml to match my project specifications; to use the jdbc resources etc. It is after this change that I find this error...

The exception is class not found. Find the library that has this class.

Ensure that you put all required libraries (*.jar) in WEB-INF/lib folder.

Some of the configuration files must have got corrupted. I faced this issue and fixed it by uninstaling and reinstalling tomcat. I use tomcat 7. But you can use the same commands with any version

sudo apt-get purge tomcat7
sudo apt-get install tomcat7

Now when you run the server it will show write or read failed in several files. Just give write and read permissions to those directories

chmod -R a+r {directory_name}
chmod -R a+w {directory_name}

Now go to tomcat folder and make a link of some files here

cd /usr/share/tomcat7
sudo ln -s /var/lib/tomcat7/conf conf
sudo ln -s /var/log/tomcat7 log
sudo ln -s /etc/tomcat7/policy.d/03catalina.policy conf/catalina.policy
sudo chmod -R a+rwx /usr/share/tomcat7/conf

This will solve all the problems

I had the same problem. My configuration is RHEL 7.6, Tomcat 8.5.40. I was installing and updating Tomcat using a script. I needed to update some files under the tomcat/conf directory after the initial installation. When I tried to restart tomcat, I was continually getting the following in catalina.out; and the problem was not recoverable:

org.apache.catalina.startup.Catalina start

WARNING: Unable to load server configuration from [/var/lib/tomcat/conf/server.xml]

It turns out that the cause of the problem was trying to set the ownership and mode. I was doing:

sudo chown -R tomcat:tomcat /var/lib/tomcat/conf
sudo chmod -R 600 /var/lib/tomcat/conf
sudo chmod -R 750 /var/lib/tomcat/conf/Catalina

If I set the permissions not in this blanket recursive manner. Everything remains fine, even though the end result (ownership and mode) of doing the recursive way or the manual way were exactly the same. It's an odd one; I hope this help someone. It took me two and a half days to track down this problem.

In my case, I accidentally deleted </host> (closing tag line) in server.xml. After adding again the closing tag, the issue got resolved.
