In August 2010 I was contracted to performance tune a LAMP server to handle approximately 70 full page loads per second which equated to 4,250 concurrent virtual users. We ended up doubling this expectation to 140 full page loads per second without striking issue. If this speed was maintained for 24 hours it would equate to over 12 million hits per day. This article will let you know how we achieved it.

Q. How can I import a MySQL dumpfile into my database? My old hosting provider gave me data.sql file. I do have access via ssh to server. I'm using CentOS Linux 5 server.
A. You can easily restore or import MySQL data with mysql command itself. First you need to login to your system using ssh or putty (from Windows based system). For example:
In the enterprise Linux network, it is necessary to keep track of server shutdown and reboot time. Most of you may have used the shutdown / reboot command.
last command searches back through the file /var/log/wtmp (or the file designated by the -f flag) and displays a list of all users logged in (and out) since that file was created. The pseudo user reboot logs in each time the system is rebooted. Thus last reboot will show a log of all reboots since the log file was created.

Step 1: Login to the server as root in SSH.
