There are so many tips you can google, some are very complicated, some are useless.
Now I want to share my experience to reduce memory usage of Apache on Centos server.
You have to have Webmin installed on your server first.
Server >> Apache Webserver >> Global configuration >> Processes and Limits
There are three figures you can change to reduce the memory usage.
Maximum spare server processes: 20 (default), I changed it to 10
Minimum spare server processes: 5 (default), I changed it to 4
Initial server processes: 8 (default), I changed it to 5.
The total memory usage reduced from about 500M to 300M.
Every httpd occupied 20M roughly. So I cut 10 server processes, is to save about 200M memory.
I bought a adapter or converter which can convert an IDE hard disk or SATA disk to a USB external drive.
1. Connect laptop 2.5" harddisk (IDE/SATA) to any computer via USB without power adaptor
2. Connect desktop 3.5" harddisk (IDE/SATA) to any computer via USB with power adaptor
3. Connect CD-ROM/CD-RW/DVD-ROM/DVD-RW (IDE/SATA) to any computer with power adaptor.
I tested it with my 3.5" 40GB Maxtor hard disk. It works on my Windows XP and O!play media player.
It is $20 plus tax.
I bought a new player last friday at Anitec. I spend $118.97 incl. tax.
It works very well to play video, audio, photos from my USB disk or shared folder of other PC.
Let's see the content of the box.
There are AV cable, Power Adapter, Remote Controller, Quick Start Guide(booklet) and User Manual CD (From left to right, TOP)
The player is a black box.
It has one eSATA/USB combo port, and one USB port at left side, AV out ports, Optical s/pdif out port, one HDMI out port, and Lan port at the back of the player.
The media files can be stored at USB flash disk, USB/eSATA hard disk drive connect directly to the player. The other way is the player can connect the PC/Notebook within a LAN.
If put the files in PC, the folder should be shared, then the media player can access by local area network.
Canadian Web Hosting offers two different types of VPS hosting, Linux and Windows running under Citrix Xenserver. They can choose different operating systems such as Windows 2008, Redhat, Debian, CentOS, SUSE, and Fedora.
As we know, many people use Windows desktop OS and know Windows only. So when they want to choose a VPS, they pick up Windows VPS.
Let's look at the the service and price Canadian Web Hosting provided.
Say, VPS-Win 1000.
It has 20GB disk space, 1000GB Bandwidth. It is good enough for one or two busy forum or sites.
Two IPs. It is so good to have the individual IP. Especially for commerce site.
512M memory, 256Mhz CPU, are also OK.
For experienced Windows user, server is a little bit different. So Remote Desktop can help them manage Windows VPS server without problem. MS SQL 2008 express is included.
Firewall and Intrusion Protection are very important. I heard so many cases that site was hacked, site was hijacked. Just because the security issues.
So if you have a lot of Windows experience, and start to launch an web site, I recommend you buy this Windows VPS for $85.40/month.
