AJP issue

[Joshua Kim]

Hi,

I am installing Dspace 7.1 on Centos 8 server. I have an AJP issue. Can someone help me out? I use Apache 2.4.x and Tomcat 9. x

1. At the Tomcat server.xml file, I added this:

<Connector protocol="AJP/1.3" port="8009" redirectPort="8443" URIEncoding="UTF-8" />

2. And then, ssl.conf file, 

 ProxyPass /server ajp://xxx.udel.edu:8009/server
 ProxyPassReverse /server ajp://xxx.udel.edu:8009/server

3. Apache modules (proxy related) are included in 000-proxy.file 

4. However, when I run Apache, the error says

[proxy:error] [pid 145479:tid 139621937510144] (111)Connection refu
sed: AH00957: AJP: attempt to connect to 128.175.xxx.xxx:8009 (xxx.udel.edu) failed
