CentOS最小化安装,然后先新建一个repo#vi/etc/yum.repos.d/centos.21andy.com.repo放入如下内容[21Andy.com]name21Andy.comPackagesforEnterpriseLinux5-$basearchbaseurlhttp://www.21andy.c
CentOS 最小化安装,然后先新建一个 repo
# vi /etc/yum.repos.d/centos.21andy.com.repo
放入如下内容
[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
启用 EPEL repo
CentOS i386 输入如下命令
rpm
-ihv http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm
CentOS x86_64 输入如下命令
rpm
-ihv http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-3.noarch.rpm
然后导入key
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL
OK,一键安装吧
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
最后 yum -y update 一下,全是最新的
如果 nginx 你要用 0.7.65 最新稳定版,把
yum -y install nginx
换成
yum -y install nginx-stable
就可以了
装完你已经可以这样玩了
service mysqld start
service php-fpm start
service nginx start
别忘了设置开机启动
chkconfig --level 345 mysqld on
chkconfig --level 345 php-fpm on
chkconfig --level 345 nginx on
配置文件都在 /etc 下自己找
看看安装多自动

以下分别测试我本地的虚拟机和 VPS 上 Nginx + php-fpm 的性能
我的本机虚拟机测试,配置为PD930 双核3.0G,2G内存,给虚拟机分配的是 1G 内存,安装的系统为 CentOS 5.4
64bit
测试内容为
500 并发测试,CPU使用率到了30%,系统负载在10左右,页面打开还是飞快

5000
并发测试,CPU使用率30%,系统负载到了35,页面打还速度还不错,看了这数据,前些天说的那个1500万PHP请求也没啥了

还不过瘾,变态一下,10000并发
10000
并发,CPU使用还是不到30%,系统负载从60左右一直升到1000左右,晕死!居然还能打开!只是有点卡!负载到600多的时候居然不卡!疯了,我这还是虚拟机,webbench
还是在自己机上开的,汗,太强了

而我的 VPS , 2G内存,8核CPU测试,但我不是使用上面的 yum 安装,而是全用源代码编译安装的,测试结果如下:
500并发,CPU使用率20%,负载2左右
# webbench -c 500 -t 30 http://127.0.0.1/index.php

Speed=120520 pages/min, -36244332 bytes/sec.
Requests: 60260 susceed, 0 failed.
2000并发,CPU使用率20%左右,负载2左右,没啥变化
webbench -c 2000 -t 30 http://127.0.0.1/index.php

开到3000并发也一样,但打开页面要等几秒,突然一下出来,说明我进程开少了,还有余地。
现在我明白了前几天那个1500万PHP请求还能稳定访问是怎么回事了,哈哈,你只要CentOS 5.4 64bit,再按我上面的 yum
方法安装,也一样能顶住。
