##0.下载相关的文件
1. [pcre-8.21.tar.bz2](ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/)
2. [nginx-1.4.1.tar.gz](http://nginx.org/)
3. [php-5.3.27](http://php.net/downloads.php)

##1.PCRE
系统自带的PCRE版本太低了.所以需要卸载重装。 
第一步：查看PCRE的版本 
```
$ rpm -qa | grep pcre
```
第二步：保留以前的libpcre.so.0，没有这个无法重装PCRE的
```
$ sudo cp /lib/libpcre.so.0 /lib/libpcre.so.0.back
```
第三步：卸载PCRE
```
$ sudo rpm -e --nodeps pcre-7.8-4.el6.i686 #这里的这个7.8-4.el6.i686-是我这里版本，要根据自己电脑修改
```
第四步：安装新的PCRE
```
$ tar -xj -f pcre-8.21.tar.gz
$ cd pcre-8.21
$ sudo mv /lib/libpcre.so.0.back /lib/libpcre.so.0
$ ./configure 
$ make
$ sudo make install 
```
##2.Nginx
```
$ ./configure 
$ --prefix=/usr/local/nginx 
$ --conf-path=/etc/nginx/nginx.conf 
$ --user=www  
$ --group=www 
$ --pid-path=/var/run/nginx.pid 
$ --with-http_stub_status_module 
$ --with-http_ssl_module  
$ --with-http_realip_module  
$ --with-http_flv_module 
$ --with-http_dav_module  
$ --with-http_gzip_static_module 
$ --http-log-path=/data/log/nginx/access.log 
$ --error-log-path=/data/log/nginx/error.log  
$ --without-http-cache 
$ --with-mail 
$ --with-mail_ssl_module 
$ --http-proxy-temp-path=/tmp/nginx/proxy  
$ --http-fastcgi-temp-path=/tmp/nginx/fastcgi 
$ --http-uwsgi-temp-path=/tmp/nginx/uwsgi 
$ --http-scgi-temp-path=/tmp/nginx/scgi 
$ --http-client-body-temp-path=/tmp/nginx/client 
$ make 
$ sudo make install
$ sudo /usr/local/nginx/sbin/nginx 
```
###配置, 开启PHP支持
```
$ sudo vim /usr/local/nginx/conf/nginx.conf
```
增加PHP主页
```
location / {
root html;
index index.html index.php index.htm;
}
```
开启PHP支持
```
location ~ .php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www$fastcgi_script_name;
include fastcgi_params;
}
```
注意这里的fastcgi_pass 和 fastcgi_param的"/var/www", fastcgi_pass是nginx请求到php的端口，而"/var/www"就是项目的存放路径 
```
$ sudo /usr/local/nginx/sbin/nginx
```
在浏览器输入https://127.0.0.1就可以查看Nginx的欢迎信息了
##3.PHP
这里是最小化安装，所以就不配置什么插件了
Nginx 与 PHP的通信需要使用 PHP-FPM，在php5.3.3以后，PHP-FPM以及集成到了php，如果要使用的话，在编译的时候，加一句--enable-fpm
```
$ sudo ./configure --prefix=/usr/local/php --enable-fpm
$ sudo make
$ sudo make test
$ sudo make install
```
###配置
```
$ sudo cd /usr/local/php
$ cp etc/php-fpm.conf.default etc/php-fpm.conf
$ sudo vim etc/php-fpm.conf
$ 找到[global]，去掉";pid = run/php-fpm.pid"的注释
```
##4.测试

我们之前提到了"/var/www"，我们在这里新建一个php文件，来测试环境是否搭建成功
```
$ sudo vim /var/www/info.php
```
info.php
```php
<? echo phpinfo(); ?>
```
如果之前已经开启nginx服务器，现在就不用开了
```
$ sudo /usr/local/nginx/sbin/nginx
$ sudo /usr/local/php/sbin/php-fpm
```

##5.编写快速启动和关闭的nginx与php脚本
示例：
```
$ sudo vim /etc/init.d/php-fpm
$ sudo chmod +x /etc/init.d/php-fpm
$ sudo /sbin/chkconfig php-fpm on
$ sudo /sbin/chkconfig --list php-fpm
```
成功的话
就可以看到好几个 on

测试
```
$ sudo /etc/init.d/php-fpm stop
$ sudo /etc/init.d/php-fpm start
$ sudo /etc/init.d/php-fpm restart
```
php-fpm 脚本
```
#!/bin/bash
#
# Startup script for the PHP-FPM server.
#
# chkconfig: 345 85 15
# description: PHP is an HTML-embedded scripting language
# processname: php-fpm
# config: /usr/local/php/etc/php.ini

# Source function library.
. /etc/rc.d/init.d/functions

PHP_PATH=/usr/local
DESC="php-fpm daemon"
NAME=php-fpm
# php-fpm路径
DAEMON=$PHP_PATH/php/sbin/$NAME
# 配置文件路径
CONFIGFILE=$PHP_PATH/php/etc/php-fpm.conf
# PID文件路径(在php-fpm.conf设置)
PIDFILE=$PHP_PATH/php/var/run/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME

# Gracefully exit if the package has been removed.
test -x $DAEMON || exit 0

rh_start() {
$DAEMON -y $CONFIGFILE || echo -n " already running"
}

rh_stop() {
kill -QUIT `cat $PIDFILE` || echo -n " not running"
}

rh_reload() {
kill -HUP `cat $PIDFILE` || echo -n " can't reload"
}

case "$1" in
start)
echo -n "Starting $DESC: $NAME"
rh_start
echo "."
;;
stop)
echo -n "Stopping $DESC: $NAME"
rh_stop
echo "."
;;
reload)
echo -n "Reloading $DESC configuration..."
rh_reload
echo "reloaded."
;;
restart)
echo -n "Restarting $DESC: $NAME"
rh_stop
sleep 1
rh_start
echo "."
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|restart|reload}" >&2
exit 3
;;
esac
exit 0
```

nginx 脚本
```
#!/bin/bash 
# 
#chkconfig: - 85 15 
#description: Nginx is a World Wide Web server. 
#processname: nginx 

nginx=/usr/local/nginx/sbin/nginx

case $1 in 
start) 
echo -n "Starting Nginx" 
$nginx -c $conf 
echo " done" 
;; 

stop) 
echo -n "Stopping Nginx" 
killall -9 nginx 
echo " done" 
;; 

test) 
$nginx -t -c $conf 
;; 

reload) 
echo -n "Reloading Nginx" 
ps auxww | grep nginx | grep master | awk '{print $2}' | xargs kill -HUP 
echo " done" 
;; 

restart) 
$0 stop 
$0 start 
;; 

show) 
ps -aux|grep nginx 
;; 

*) 
echo -n "Usage: $0 {start|restart|reload|stop|test|show}" 
;; 

esac
```
