Server tomcat v8.0 Server at localhot was unable to start within 45 secods

Question

I'm using STS tools and Framework Hibernate + Spring to build web application. I got error on the screen (Server tomcat v8.0 Server at localhot was unable to start within 45 secods) when build using apache.

I'have increase the limit into max 145 second, but didn't work and change configuration apache based on internet finding but still not working.

Need advice.

Thanks.

there is no max timeout for this configuration – Energetics

try increasing value or figureout where does it spend time in startup and try to make those operation lazily – Energetics

now I'm trying to increase 300 seconds.. – Licence

After increasing time what is the error i have got ? – Unschooled

do you see anything in the console output from starting tomcat? – Durante

I got same problem (at debugging time), I have breakpoint having horizontal arrow on it, then I removed it and also all breakpoints then after I debugged its works for me. – Gaut

I faced this issue today. I started my Hibernate Web App with the option Run On Server.

It was trying to connect to local MySql instance but the MySql service was stopped.

I started the MySql Service manually, retried starting the server and it worked.

Try checking all your project's dependencies are up and running.

I know its too late for you, maybe someone else will find it useful.

This is bit late. But I faced the same problem when running tomcat 8 in Eclipse. In case my case it was due to a system wide proxy and the network settings in Eclipse had been changed. I fixed it by,

Eclipse preferences -> General -> Network Connections and setting the Active Provider to Manual.

This might be the late answer but I just fixed it as below:

I am using Tomcat v9.0 and MySQL server. While starting my Spring MVC web app, I faced the same issue.

Last few lines from the log:

I tried to increase the server timeout in the tomcat configuration editor. That did not help. I searched over the Internet nothing helped. Then I launched the MySQL Workbench and whoa! I found the culprit. It said, "Unable to connect to localhost:3306". Then I realized that MySQL service may not be running. I started the MySQL service "MySQL80" and then the tomcat started within 45 seconds.

Hope this may help future readers :)
