The load balancing is different. It is kind of HA. When my real server is down then Apache forward requests to my backup server and my website never down. Excuse me, according to below diagram, is my configuration work in a real scenario? The Internet ---> Apache Reverse Proxy ---> Apache Web Server 1 (IP: 1.2.3.4, Name: Yahoo.com) ---> Apache Web Server 2 (IP: 1.2.3.5, Name: Google.com) My Virtual Host configuration is: <VirtualHost *:80> ServerName yahoo.com ErrorLog /var/log/httpd/Yahoo_error_log TransferLog /var/log/httpd/Yahoo_access_log <Location "/"> ProxyPass http://1.2.3.4/ ProxyPassReverse http://1.2.3.4/ </Location> </VirtualHost> <VirtualHost *:80> ServerName google.com ErrorLog /var/log/httpd/Google_error_log TransferLog /var/log/httpd/Google_access_log <Location "/"> ProxyPass http://1.2.3.5/ ProxyPassReverse http://1.2.3.5/ </Location> </VirtualHost> On Wednesday, March 17, 2021, 07:54:53 PM GMT+3:30, Antony Stone <antony.stone@xxxxxxxxxxxxxxxxxxxxx> wrote: On Wednesday 17 March 2021 at 17:05:37, Jason Long wrote: > Thank you. > My VM uses port forwarding.

I do not understand that. A reverse proxy which forwards incoming requests to various back-end servers based on whether they are available or not doesn't care what the names or IP addresses of those back-end servers are (they need to be configured into the reverse proxy setup, of course, but they can be totally independent of each other without problem). > If my configuration is OK, then Apache accepts a request from port 80, one of > my servers is turned off and Apache must forward it to another server. I can only repeat myself: https://httpd.apache.org/docs/2.4/mod/mod_proxy_balancer.html Antony. -- A good conversation is like a miniskirt; short enought to retain interest, but long enough to cover the subject. - Celeste Headlee Please reply to the list; please *don't* CC me. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
