Tomcat 8 says it started but is not running on Linux / CentOS

New to Tomcat. Downloaded and unpacked tomcat 8.0.9 to my CentOS web server. Placed files in /opt/tomcat.

/opt/tomcat/bin/setenv.sh contains:

JRE_HOME=/usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java CATALINA_PID="$CATALINA_BASE/tomcat.pid"

My environment variable for CATALINA_HOME is set to /opt/tomcat, double checked by using:

set | grep CATALINA_HOME

CATALINA_HOME=/opt/tomcat

Running /opt/tomcat/bin/startup.sh outputs:

/opt/tomcat/bin/startup.sh

Using CATALINA_BASE: /opt/tomcat Using CATALINA_HOME: /opt/tomcat Using CATALINA_TMPDIR: /opt/tomcat/temp Using JRE_HOME: /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java Using CLASSPATH: /opt/tomcat/bin/bootstrap.jar:/opt/tomcat/bin/tomcat-juli.jar Using CATALINA_PID: /opt/tomcat/tomcat.pid Existing PID file found during start. Removing/clearing stale PID file. Tomcat started.

However, it doesn't really start. When I check netstat there is nothing listening on 8080:

netstat -tulpn

Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1303/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1065/master tcp 0 0 :::80 :::* LISTEN 1504/httpd tcp 0 0 :::22 :::* LISTEN 1303/sshd tcp 0 0 ::1:25 :::* LISTEN 1065/master tcp 0 0 :::443 :::* LISTEN 1504/httpd

and no process named tomcat

ps aux | grep "tomcat"

root 15193 0.0 0.0 103244 852 pts/0 S+ 08:40 0:00 grep tomcat

Finally, when I run the shutdown.sh script it confirms that there was no tomcat process running even though the .pid file was created.

/opt/tomcat/bin/shutdown.sh

Using CATALINA_BASE: /opt/tomcat Using CATALINA_HOME: /opt/tomcat Using CATALINA_TMPDIR: /opt/tomcat/temp Using JRE_HOME: /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java Using CLASSPATH: /opt/tomcat/bin/bootstrap.jar:/opt/tomcat/bin/tomcat-juli.jar Using CATALINA_PID: /opt/tomcat/tomcat.pid PID file found but no matching process was found. Stop aborted.

Any help is greatly appreciated!!!!

JRE_HOME variable was incorrect. It was pointed to the actual java binary rather than the java folder.

JRE_HOME=/usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java

was replaced with:

JRE_HOME=/usr/lib/jvm/jre-1.7.0-openjdk.x86_64

in the $CATALINA_HOME/bin/setenv.sh file.

Discovered the problem after looking at the $CATALINA_HOME/logs/catalina.out file and seeing error messaging that the JRE_HOME variable was not a valid folder.
