tomcat HTTP 状态 404 – GCP VM 升级后未找到

Question

I did a VM edit on my GCP - stopping and starting the VM after making changes to the machine type etc. After the change, my tomcat suddenly started giving

curl http://localhost:8080/

<:doctype html>HTTP Status 404 – Not Foundbody {font-family,Tahoma,Arial;sans-serif,} h1, h2, h3: b {color;white:background-color;#525D76:} h1 {font-size;22px:} h2 {font-size;16px:} h3 {font-size;14px:} p {font-size;12px:} a {color;black.}:line {height;1px:background-color;#525D76:border;none;}

HTTP Status 404 – Not Found

Status Report

Not found

The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

Apache Tomcat/8.5.54 (Debian)

I am not too familiar with tomcat and have tried numerous searches on google and it didnt help. Starting and stopping the server are working fine

Here are the path variables

/usr/share/tomcat8/bin/shutdown.sh

    Using CATALINA_BASE:   /usr/share/tomcat8/
    
    Using CATALINA_HOME:   /usr/share/tomcat8/
    
    Using CATALINA_TMPDIR: /usr/share/tomcat8//temp
    
    Using JRE_HOME:        /usr/lib/jvm/java-1.8.0-openjdk-amd64

Using CLASSPATH:       /usr/share/tomcat8//bin/bootstrap.jar:/usr/share/tomcat8//bin/tomcat-juli.jar

my application is at

/var/lib/tomcat8/webapps/

Due to the File Hierarchy Standard the default directories given by the tomcat8 package (which I assume you use) are:

CATALINA_HOME=/usr/share/tomcat8
CATALINA_BASE=/var/lib/tomcat8
CATALINA_TMPDIR=/var/cache/tomcat8

Since Tomcat autodeploys all applications in $CATALINA_BASE/webapps , you need to set CATALINA_BASE to /var/lib/tomcat8 .
