Do a port translation... J

This is a good explanation. The only other question that partially remains unanswered is that if I run apacheN on port 80 (and access my site as http://mysite.com) and run apacheN+1 on port 8080 (and access site as http://mysecondsite.com:8080) - what can i do special to access http://mysecondsite.com:8080 without the port number (as if it was running on port 80). Did you get what I was trying to say? Is this a legtimate question? :) On Jan 18, 2008 11:13 PM, Axel-Stephane SMORGRAV <[EMAIL PROTECTED]> wrote: You can have as many instances of Apache as you wish on a Unix box. On Windows, I do not know but I suppose you can. Just like two Vhosts, two servers cannot bind the same IP/port combo. What I do is that I make a server root for each instance of Apache. In that server root I create the directories bin, conf, cgi-bin and htdocs. I create a log directory on another disk partition. In the bin directory you need a copy of apachectl which will somehow start httpd pointing to the right configuration file. You may for example hard-code the paths to log directory, conf directory etc. In my case I modified apachectl so that it automatically figures out where to get the config file from based on the directory in which the script is located. By typing "/servers/apacheN/bin/apachectl start", I start instance N. My apachectl script determines the script path, does 'dirname' to find the name of the parent directory which is the server root. A 'filename' on the server root will yield the instance name which can be appended to the log root path /logs to obtain /logs/apacheN. Instance configurations: /servers |----->apacheN | |-----> bin (contains only apachectl and an envvars file with LD_LIBRARY_PATH and some other environment vars) | |-----> conf | |-----> htdocs (the document root of this instance) | |-----> cgi-bin | |----->apacheN+1 |-----> bin |-----> conf |-----> htdocs |-----> cgi-bin Log files: /logs |----->apacheN |----->apacheN+1 Apache distribution: /opt/apache2 |-----> bin |-----> lib |-----> modules |-----> include |-----> manual |-----> icons Hope this helps -ascs -----Message d'origine----- De : Krist van Besien [mailto:[EMAIL PROTECTED] Envoyé : vendredi 18 janvier 2008 15:49 À : users@httpd.apache.org Objet : Re: [EMAIL PROTECTED] Multiple Instances of Apache On Jan 18, 2008 3:22 PM, Mandy Singh < [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: > Hi Everyone, > > I would like to know the experts thoughts on having multiple instances > of apache on the same box. > > Suppose I run an app off an instance of apache, then using VHosts add > 2-3 diff mini sites to it. > > If due to some reason one of the app causes apache to get hung, all my > apps become inaccessible. > > In such a scenario, since app 3 is extremely important is it > adivisable to have another instance of apache running off the same box > and serving app3 so that is away from my main app (that sometimes causes > problems)? You can have multiple apaches on one box. They will all have to be bound to a different port however. What you could do is have for example a main apache on port 80, and three separate apaches for each app on eg. ports 8080, 8081, and 8082. In you main apache you then proxy requests for the three different apps to the correct server. This gives you a couple of things: - Each app runs in its own space. - Each app can run under a different user. - With port nrs > 1024 a non root user can start - stop the server.
