To configure Apache24 to display a customized error page when Tomcat is down using mod_jk, follow these steps:
Create a custom error page Create a custom HTML or PHP error page and save it as, for example, tomcat-down.html or tomcat-down.php.
Configure the Tomcat connection in Apache Edit the Apache configuration file httpd.conf or a virtual host file and add the following lines to configure the connection to Tomcat using mod_jk:
LoadModule jk_module modules/mod_jk.so
JkWorkersFile conf/workers.properties
JkShmFile logs/mod_jk.shm
JkLogFile logs/mod_jk.log
JkLogLevel info
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkMount /* worker1
Here worker1 is the name of the Tomcat worker specified in the workers.properties file.
ErrorDocument 503 /tomcat-down.html
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ /tomcat-down.html [L,R=503]
Here, tomcat-down.html is the name of the custom error page created in step 1.
Note: Some additional Tomcat and modjk configurations may be required depending on the specific setup. It is recommended to consult the documentation for Apache, Tomcat, and modjk for more details.
