Top Forums Web Development Perhaps, different websites on same Apache server. Post 302458458 by malcolmpdx on Friday 1st of October 2010 12:00:08 AM

Really, the only way to do this functionally is with virtualization of the host(s). Or running them on separate boxes.

Consider a request to the two different servers. Assume two different IP addresses on different subnets, different DNS domains, and different DNS servers providing those zones. Even consider the machine they're being hosted on being multi-homed, with two different paths to the IP addresses for each site.

If they're still running on the same apache process on the same box, you can tell.

Fire up your favorite stress tester and point it at one of the sites, and start hitting it hard - and the other one will likely slow down.

It's possible that if you ran one apache process on one port, and and entirely separate one on another port, and you tuned the heck out of them, this sort of evidence might be hard to discover. But really, eventually, someone would be able to tell.

Now, if you're asking how to just keep them separate functionally, different IPs and different DNS along with a decent apache virtual configuration will provide that. Of course, if you bring down one (i.e. apache is restarted or stopped) you will bring down the other one as well. So, if you need that sort of separation, look at virtualization, or run them on different hosts.

NAME
apache - Apache hypertext transfer protocol server overview DESCRIPTION
apache consists of a main server daemon, loadable server modules, some additional support utilities, configuration files, and documenta- tion. FILES
The apache HTTPD server is integrated with Solaris. The following files specify the installation locations for apache: /etc/apache Contains server configuration files. A newly-installed server must be manually configured before use. Typically this involves copying httpd.conf-example to the httpd.conf file and making local configuration adjustments. /usr/apache/bin Contains the httpd executable as well as other utility programs. /usr/apache/htdocs Contains the Apache manual in HTML format. This documentation is accessible by way of a link on the server test page that gets installed upon fresh installation. /usr/apache/include Contains the Apache header files, which are needed for building various optional server extensions with apxs(8) /usr/apache/jserv Contains documention for the mod_jserv java servlet module. Documention can be read with a web browser using the url: file:/usr/apache/jserv/docs/index.html /usr/apache/libexec Contains loadable modules (DSOs) supplied with the server. Any modules which are added using apxs(8)are also copied into this directory. /usr/apache/man Contains man pages for the server, utility programs, and mod_perl. Add this directory to your MANPATH to read the Apache man pages. See NOTES. /usr/apache/perl5 Contains the modules and library files used by the mod_perl extension to Apache. /var/apache/cgi-bin Default location for the CGI scripts. This can be changed by altering the httpd.conf file and restarting the server. /var/apache/htdocs Default document root. This can be changed by altering the httpd.conf file and restarting the server. /var/apache/icons Icons used by the server. This normally shouldn't need to be changed. /var/apache/logs Contains server log files. The formats, names, and locations of the files in this directory can be altered by various configuration directives in the httpd.conf file. /var/apache/proxy Directory used to cache pages if the caching feature of mod_proxy is enabled in the httpd.conf file. The location of the cache can also be changed by changing the proxy configuration in the httpd.conf file. ATTRIBUTES

In addition to the documentation and man pages included with Solaris, more information is available at http://www.apache.org The Apache man pages are provided with the programming modules. To view the manual pages for the Apache modules with the man command, add /usr/apache/man to the MANPATH environment variable. See man(1) for more information. Running catman(1M) on the Apache manual pages is not supported. SunOS 5.11 8 Aug 2000 apache(1M)
