原因

Port 8509 lytter ikke etter lokalverten.

解决方案

1. Logg på Avamar-serveren som administratorbruker, og oppgrader til rotbrukeren: 

2. Sikkerhetskopier den eksisterende konfigurasjonsfilen for server.xml:  
cp -p /usr/local/avamar-tomcat/conf/server.xml /usr/local/avamar-tomcat/conf/server.xml-orig
cp -p  /usr/local/avamar/etc/server.xml /usr/local/avamar/etc/server.xml-orig

3. Rediger /usr/local/avamar-tomcat/conf/server.xml  og /usr/local/avamar/etc/server.xml. Legg til linjen som er uthevet nedenfor:  
    
    
     
 
4. Lagre og lukk filen. 

5. Start tomcat og Apache på nytt:  
emwebapp.sh --restart
service apache2 restart
