How to check Apache if it is installed on server or not? and ho it can help in increasing blog speed?
Apache, depending on the Linux distro you are using, is most times installed by default...check for "httpd" processes, better yet just put the IP of the server in a browser to see if the default Apache page shows up, or just browse to a random directory in your site and you should see the httpd server's signature in a directory index.
depends on how it was installed for debian, or its derivitives (ubuntu, knoppix etc), dpkg -l | grep apache for redhat and derivatives (centOS, Fedora etc): rpm -qa | grep httpd if its not rpm or deb based, or if was installed by source, see if its running (ps ax | grep httpd or ps ax | grep apache), or has any config: is there a directory called httpd or apache in /etc, /usr/local, or /var/log could also check if the default port is open: telnet localhost 80 hope that helps Will need more information before discussing increasing blog speed: what's your Linux distribution, PC/Server spec, blogging s/w, traffic expectations, connection speed, apache settings etc. etc.
Run these commands: find / -iname apachectl -exec ls netstat -tap | grep 80 ls /etc/init.d/ | grep apache ; ls /etc/init.d | grep httpd ; sudo /etc/init.d/apache status ; sudo /etc/init.d/httpd status if one of these outputs something other than errors you probably have apache.
