nginx本身不能处理PHP,它只是个web服务器,当接收到请求后,如果是php请求,则发给php解释器处理,并把结果返回给客户端。

nginx一般是把请求发fastcgi管理进程处理,fascgi管理进程选择cgi子进程处理结果并返回被nginx

本文以php-fpm为例介绍如何使nginx支持PHP

一、编译安装php-fpm

什么是PHP-FPM

PHP-FPM是一个PHP FastCGI管理器,是只用于PHP的,可以在 http://php-fpm.org/download下载得到.

PHP-FPM其实是PHP源代码的一个补丁,旨在将FastCGI进程管理整合进PHP包中。必须将它patch到你的PHP源代码中,在编译安装PHP后才可以使用。

新版PHP已经集成php-fpm了,不再是第三方的包了,推荐使用。PHP-FPM提供了更好的PHP进程管理方式,可以有效控制内存和进程、可以平滑重载PHP配置,比spawn-fcgi具有更多有点,所以被PHP官方收录了。在./configure的时候带 –enable-fpm参数即可开启PHP-FPM。

新版php-fpm安装(推荐安装方式)

wget http://cn2.php.net/distributions/php-5.4.7.tar.gz

tar zvxf php-5.4.7.tar.gz

cd php-5.4.7

./configure --prefix=/usr/local/php --enable-fastcgi --enable-fpm --with-mcrypt --with-zlib --enable-mbstring --disable-pdo --with-curl --disable-debug --enable-pic --disable-rpath --enable-inline-optimization --with-bz2 --with-xml --with-zlib --enable-sockets --enable-sysvsem --enable-sysvshm --enable-pcntl --enable-mbregex --with-mhash --enable-xslt --enable-memcache --enable-zip --with-pcre-regex --with-mysql

make all install

旧版手动打补丁php-fpm安装

wget http://cn2.php.net/get/php-5.2.17.tar.gz
wget http://php-fpm.org/downloads/php-5.2.17-fpm-0.5.14.diff.gz

tar zvxf php-5.2.17.tar.gz
gzip -cd php-5.2.17-fpm-0.5.14.diff.gz | patch -d php-5.2.17 -p1
cd php-5.2.17
./configure --prefix=/usr/local/php --enable-fastcgi --enable-fpm --with-mcrypt --with-zlib --enable-mbstring --disable-pdo --with-curl --disable-debug --enable-pic --disable-rpath --enable-inline-optimization --with-bz2 --with-xml --with-zlib --enable-sockets --enable-sysvsem --enable-sysvshm --enable-pcntl --enable-mbregex --with-mhash --enable-xslt --enable-memcache --enable-zip --with-pcre-regex --with-mysql

make all install

 

以上两种方式都可以安装php-fpm,安装后内容放在/usr/local/php目录下

nginx php

cd /usr/local/php

cp etc/php-fpm.conf.default etc/php-fpm.conf

修改

vi etc/php-fpm.conf.default etc/php-fpm.conf

user = www-data
group = www-data

 

二、编译安装nginx

然后按照http://www.nginx.cn/install 安装nginx

 

三、修改nginx配置文件以支持php-fpm

nginx安装完成后,修改nginx配置文件为,nginx.conf

其中server段增加如下配置,注意标红内容配置,否则会出现No input file specified.错误

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}

 

四、创建测试php文件

创建php文件

在/usr/local/nginx/html下创建index.php文件,输入如下内容

echo phpinfo(); ?>

 

五、启动服务

启动php-fpm和nginx

/usr/local/php/sbin/php-fpm (手动打补丁的启动方式/usr/local/php/sbin/php-fpm start)

sudo /usr/local/nginx/nginx

 

六、浏览器访问

访问http://你的服务器ip/index.php,皆可以见到php信息了。

nginx php

 

安装php-fpm时可能遇到的错误:

1.phpconfigure时出错

configure: error: XML configuration could not be found
apt-get install libxml2 libxml2-dev  (ubuntu下)
yum -y install libxml2 libxml2-devel(centos下)

 

2. Please reinstall the BZip2 distribution

wget http://www.bzip.org/1.0.5/bzip2-1.0.5.tar.gz
tar -zxvf bzip2-1.0.5.tar.gz
cd bzip2-1.0.5
make
make install
3.php的配置文件中有一行--with-mysql=/usr。安装的时候提示:
configure: error: Cannot find MySQL header files under yes.
Note that the MySQL client library is not bundled anymore.

这是由于安装mysql时没有安装mysql头文件,或者是路径指定不正确,php找不到mysql的头文件引起的错误提示。
解决方法。
(1.) 查看你的系统有没有安装mysql header
find / -name mysql.h
如果有。请指定--with-mysql=/跟你的正常路径。
如果没有。请看下一步。
(2.)redhat安装
rpm -ivh MySQL-devel-4.1.12-1.i386.rpm
(3.)ubuntu安装
apt-get install libmysqlclient15-dev
(4.)最后一步php的配置选项添加--with-mysql=/usr即可!
4.No input file specified.

location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}

 

5.如果php configure时缺库,可以先安装库(ubuntu下)

sudo apt-get install make bison flex gcc patch autoconf subversion locate
sudo apt-get install libxml2-dev libbz2-dev libpcre3-dev libssl-dev zlib1g-dev libmcrypt-dev libmhash-dev libmhash2 libcurl4-openssl-dev libpq-dev libpq5 libsyck0-dev
