Unable to access tomcat server [RHEL]

[mhassan1]

I installed tomcat 8.033 on RHEL following the Thingworx 7.4 installation guide from the website. When running sudo systemctl status tomcat I get the following

â tomcat.service - Apache Tomcat Web Application Container

   Loaded: loaded (/usr/lib/systemd/system/tomcat.service; enabled; vendor preset: disabled)

However, I am still unable to access tomcat server from the browser.

Hi Muhammad Hassan,

Could you please verify the below steps:

• Open the server.xml file located in tomcat install directory </usr/share/tomcat8/8.033/conf/server.xml>

• Comment out or remove this section:

• Paste the below contents directly below:

<Connector port="443" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="150" SSLEnabled="true" scheme="https" secure="true" keystoreFile="/usr/share/tomcat8/8.0.33/conf/.keystore" keystorePass="Enter keystorepassword" clientAuth="false" sslProtocol="TLS" />

• Save the file and restart Tomcat.

If this doesn't resolve the issue please share the catalina.out file from Tomcat folder

I have tried your solution, however it still did not work. I looked at the catalina file and it might be a java related issue. However, I installed java as per the guide and rechecked my steps. I did not paste the whole log file since it is too long. Here is part of the log file

Hi Muhammad Hassan,

Could you please review if /usr/lib/jvm/jdk1.8.0.92 folder exists or not?

or please follow the below steps and share the output of these commands:

• cd /usr/lib/jvm

Also, could you please provide the java version that you have installed on the system?
