Hi, I know there are such threads, but what I would like to do is a little bit different, so I would like to hear any opionons on the matter. What I currently have is Apache + Ispconfig3 latest versions for production, which I installed 1 year ago using the perfect server tutorial. I want to add Varnish to the set-up, but leaving anything on the server to its defaults and only redirecting the traffic to Varnish using iptables rule like this one for example: #iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 6081 This way I will not have to change anything to the Varnish configuration other than the port it listens to, if I want it to listen on other port than its default one. No changes will be made to Ispconfig3, or Apache as well. I like to keep the things as much to their defaults as possible. Simply installing Varnish on the server via apt-get install Varnish and applying the rule above. So what do you think ? Will it work, will there be any issues and should I redirect SSL port as well, or other ports. The iptables is lightweight so I assume there will not be any load issues, but still, has anyone tried that? Please let me know your thoughts.
I haven't tried it with iptables, until now I used the normal approach with apache HTTP port listening on localhost plus different port and varnish listening on port 80 globally.
Hi Till, thank you for the follow-up on the matter. I have not tried it (at least for now) as well. But I would like to keep everything as much stock as it could be. This way I will not have to edit the ISPconfig template for creating Vhosts in Apache for the port, actually I will not have to edit anything. I suppose it will be better during updates of the server, that everything is stock. I will try it soon and let you know how it goes. In the meant time, if anyone is using this configuration, please let me know, if I should watch for something ...
