I check "ps -ef | grep tomcat", it returns "

"

"netstat -ln | grep 8088", it returns " tcp6 0 0 :::8088 :::* LISTEN "

does this mean that the tomcat is running?

if so, why I can't open the url with ip_address:8088? last night I can see the tomcat page with url ip_address:8088. This morning, I shutdown the tomcat by "shutdown.sh run", it returns "

"

then I start tomcat by "catalina.sh run", the same log as I post above, when I try to access the ip_address:8088, the page is keeping running,but nothing display out. It has been 2 hrs, the page tag is still running, nothing displayed out. I didn't do anything after last night I see the tomcat page showed up.

then I tried to shutdown the tomcat with "shutdown.sh run", it returns "

Can anyone tell me why is that happen? and what should I do?

when I come back afternoon, I found the page ip_address:8080. Does this mean my tomcat took so long (several hours) to start up? It must not be normal, can anyone help me? — Roger Luo, Nov 23 '15 at 00:38

Tomcat should start up in seconds, especially if you've just downloaded and unzipped it.

I'd suggest checking the running tomcat processes and killing them first. From the output from your shutdown command, it doesn't look like it was shutdown cleanly (note the "usage" feedback -- use either ./shutdown.sh or ./catalina.sh stop).

Next, check the $CATALINA_HOME/conf/server.xml. It seems like you may have been changing the default ports. 8080 is the default port for Tomcat, not 8088 (and 8005 is the default shutdown port, not 8006) so make sure you have these set the way you want before you start the server.

I'd definitely recommend reading through the documentation also http://tomcat.apache.org/tomcat-8.0-doc/RUNNING.txt

Hi Jason, I download tomcat 7, just try to check if tomcat run. I only unzip it on /opt/tomcat_7 folder, then I run "catalina.sh run" to start up tomcat, but the log shows it stuck at "INFO: Deploying web application directory /opt/tomcat_7/apache-tomcat-7.0.65/webapps/ROOT", and it takes a lot of time (hours of time). I only keep "ROOT" in webapps. – Roger Luo Nov 25 '15 at 02:22
