CentOS system LNMP production environment configuration process

CentOS minimal installation, and then create a new repo first

# vi /etc/yum.repos.d/centos.21andy.com.repo
Put the following content
[21Andy.com]
name=21Andy.com Packages for Enterprise Linux 5 –
$basearch
baseurl=http://www.21andy.com/centos/5/$basearch/
enabled=1
gpgcheck=0
protect=1
Enable EPEL repo
CentOS i386 enter the following command
rpm
-ihv http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm
CentOS x86_64 Enter the following command
rpm
-ihv http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-3.noarch.rpm
Then import key
rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL
OK, one-click installation
yum -y install nginx mysql-server php-fpm php-cli php-pdo php-mysql
php-mcrypt php-mbstring php-gd php-tidy php-xml php-xmlrpc php-pear
php-pecl-memcache php-eaccelerator
Finally, run yum -y update, all are the latest
If you want to use the latest stable version of nginx 0.7.65, put
yum -y install nginx
Change to
yum -y install nginx-stable
That’s it
After installing, you can already play like this
service mysqld start
service php-fpm start
service nginx start
Don’t forget to set it to start at boot
chkconfig –level 345 mysqld on
chkconfig –level 345 php-fpm on
chkconfig –level 345 nginx on
The configuration files are all found under /etc
See how the installation is automatic

The following test the performance of Nginx + php-fpm on my local virtual machine and VPS respectively
My local virtual machine test is configured as PD930 dual-core 3.0G, 2G memory, 1G memory is allocated to the virtual machine, and the installed system is CentOS 5.4
64bit
The test content is

In the 500 concurrent test, the CPU usage rate reached 30%, the system load was around 10, and the page opened quickly

In the concurrent test, the CPU usage rate is 30%, the system load reaches 35, and the page playback speed is not bad. After reading this data, the 15 million PHP requests mentioned a few days ago are nothing.

It’s not enough, let’s be abnormal, 10000 concurrent
10000
Concurrently, the CPU usage is still less than 30%, and the system load has risen from about 60 to about 1000, and we are sick! It can still be opened! Just a little stuck! When the load reaches more than 600, it does not freeze! Crazy, I’m still a virtual machine, webbench
It’s still on my own machine, sweat, it’s too strong

And my VPS, 2G memory, 8-core CPU test, but I did not use the above yum installation, but compiled and installed it with source code, the test results are as follows:
500 concurrency, CPU usage 20%, load about 2

The same is true for 3000 concurrency, but it takes a few seconds to open the page, and suddenly it comes out, indicating that I have fewer processes and there is still room.
Now I understand why the 15 million PHP requests can still be accessed stably a few days ago, haha, you only need CentOS 5.4 64bit, and then press my above yum
Method installation, also can withstand.
