3.3.5 启动php-cgi进程
监听127.0.0.1的9000端口，进程数为200（如果服务器内存小于3GB，可以只开启64个进程），用户为www：
ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm start
注：/usr/local/webserver/php/sbin/php-fpm还有其他参数，包括：start|stop|quit|restart|reload|logrotate，修改php.ini后不重启php-cgi，重新加载配置文件使用reload。
# 关于ulimit -SHn
Linux 默认打开文件数为1024个，通过ulimit -a 可以查看open files
显然这个数值在高并发的WEB服务器上是不够用的，根据您的需要可使用ulimit命令修改此值，如：
ulimit -SHn 65535
修改后，重启服务器将失效，为使开机即生效，可修改/etc/security/limits.conf
vim /etc/security/limits.conf
在：
#* soft core 0
#* hard rss 10000
#@student hard nproc 20
#@faculty soft nproc 20
#@faculty hard nproc 50
#ftp hard nproc 0
#@student - maxlogins 4
后加入这两行：
* soft nofile 65532 #Linux对当前用户的进程同时打开的文件数量的软限制(soft limit)
* hard nofile 65533 #Linux对当前用户的进程同时打开的文件数量的硬限制(hardlimit)
# End of file
就可以不用每次重启服务器的时候，都输入该命令了。
4. 编译安装Nginx
4.1 软件下载
wget http://blog.s135.com/soft/linux/nginx_php/nginx/nginx-0.8.15.tar.gz
# perl语言兼容正则表达式，是一个用C语言编写的正则表达式函数库。
wget http://blog.s135.com/soft/linux/nginx_php/pcre/pcre-7.9.tar.gz
4.2 安装Nginx
4.2.1 安装Nginx所需的pcre库
tar zxvf pcre-7.9.tar.gz
cd pcre-7.9/
./configure
make
make install
cd ../
4.2.2 安装Nginx
tar zxvf nginx-0.8.15.tar.gz
cd nginx-0.8.15/
./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module –with-http_ssl_module
make
make install
cd ../
4.3 Nginx配置
4.3.1 创建Nginx日志目录
mkdir -p /data1/logs
chmod +w /data1/logs
chown -R www:www /data1/logs
4.3.2 创建Nginx配置文件
在/usr/local/webserver/nginx/conf/目录中创建nginx.conf文件：
rm -f /usr/local/webserver/nginx/conf/nginx.conf
vim /usr/local/webserver/nginx/conf/nginx.conf
输入以下内容：
user www www;
worker_processes 8;
error_log /data1/logs/nginx_error.log crit;
pid /usr/local/webserver/nginx/nginx.pid;
#指定最大文件描述数量.
worker_rlimit_nofile 65535;
events
{
# 使用网络I/O模型，Linux系统推荐epoll模型；
use epoll;
# 允许的连接数
worker_connections 65535;
}
http
{
include mime.types;
default_type application/octet-stream;
#charset gb2312;
