Can we use a solaris box as a web server?
If yes then can any one can explain each and every steps to configure a Solaris web server?
Yes you can use solaris as an webserver. You could use it with apache standard.
svcs -a |grep apa
svcadm enable svc:/network/http:apache2
or via legacy run
/etc/init.d/apache start
But you can search google there is lots of information available about this.
Sure. What Solaris release are you using ?
Not just for Web server , with Solaris zones you can easily set up apache, mail, dhcp, mail server . Most of all is important that Solaris is very very capable to serve this servers because Solaris itself is one of most stable OS in world.
Heck, with Solaris zones you can easily protect whole network if you configure Solaris to work as cheap x86 firewall
