Nginx PHP-FPM Installation Configuration

Nginx itself can not handle PHP, it is just a Web server, when the request is received, if it is a PHP request, then sent to the PHP interpreter processing, and the results returned to the client.

Nginx is generally the request to send fastcgi management process processing, FASCGI management process Select the CGI subprocess processing results and return to be Nginx

This article takes php-fpm as an example to explain how to make Nginx support PHP

I. Compiling and installing PHP-FPM

What is PHP-FPM

PHP-FPM is a PHP fastcgi manager that is only used in PHP and can be downloaded in http://php-fpm.org/download.

PHP-FPM is actually a patch of PHP source code, designed to integrate FASTCGI process management into the PHP package. It must be patch to your PHP source code and can be used only after compiling and installing PHP.

The new version of PHP has been integrated PHP-FPM, no longer a third party package, recommended use. PHP-FPM provides a better way to manage PHP processes, can effectively control memory and process, can smooth overload PHP configuration, than spawn-fcgi has more advantages, so by the official PHP included. In the./configure with the –ENABLE-FPM parameter can be opened PHP-FPM, the other parameters are configured PHP, the meaning of the specific options can be viewed here.

Prepare before installation

Execute under CentOS

Yum-y install gcc automake autoconflibtool make

Yum-y Install gcc gcc-c++ glibc

Yum-y Install Libmcrypt-devel mhash-devellibxslt-devel \

Libjpeg libjpeg-devel libpng libpng-develfreetype freetype-devel libxml2 \

Zlib zlib-devel glibc glibc-devel glib2glib2-devel bzip2 \

ncurses ncurses-devel Curl Curl-devele2fsprogs e2fsprogs-devel \

krb5 krb5-devel libidn libidn-devel opensslopenssl-devel

Tips:

Setting up Install Process

No Package Libmcrypt-devel available.

No Package Mhash-devel available.

Source Code manual Installation Libmcrypt and Mhash

New PHP-FPM installation (recommended installation method)

Wgethttp://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/php5.4--ENABLE-FPM--with-mcrypt=/usr/local/libmcrypt\

--enable-mbstring--disable-pdo--with-curl--disable-debug--disable-rpath \

--ENABLE-INLINE-OPTIMIZATION--WITH-BZ2--with-zlib--enable-sockets\

--enable-sysvsem--enable-sysvshm--enable-pcntl--enable-mbregex \

--with-mhash=/usr/local/mhash--enable-zip--with-pcre-regex--with-mysql--with-mysqli \

--with-gd--with-jpeg-dir

Make all Install

Both of the above can be installed PHP-FPM, after the installation of content in the/usr/local/php directory

The above completes the PHP-FPM installation.

The following is the setting for the PHP-FPM run user

cd/usr/local/php

CP etc/php-fpm.conf.defaultetc/php-fpm.conf

VI etc/php-fpm.conf

Modify

user = Www-data

Group = Www-data

If the Www-data user does not exist, add the Www-data user first

Groupadd Www-data

Useradd-g Www-data Www-data

Second, modify the Nginx configuration file to support PHP-FPM

After the Nginx installation is complete, modify the Nginx configuration file to nginx.conf

The server section increases the following configuration, pay attention to the red content configuration, otherwise there will be no input filespecified. Error

# Pass the PHP scripts to FastCGI serverlistening 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;

}

Create a test PHP file

Creating PHP Files

Create the index.php file under/usr/local/nginx/html and enter the following

<?php

Echo Phpinfo ();

?>

V. Start the service

Start PHP-FPM and 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

PHP-FPM Close restart See end of article

VI. Browser access

Visit http://Your server ip/index.php, you can see the PHP information.

Errors that you may encounter when you install PHP-FPM:

1. PHP Configure Error

Configure:error:XML configuration couldnot be found

Apt-get Install LIBXML2 Libxml2-dev (Ubuntu)

Yum-y Install LIBXML2 libxml2-devel (CentOS)

2. Please reinstall the BZIP2 distribution

Wgethttp://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 has a row of--with-mysql=/usr in the configuration file.

When you install the prompt:

Configure:error:Cannot Find MySQL headerfiles under Yes.

The MySQL client library is notbundled anymore.

This is due to the installation of MySQL did not install MySQL header file, or the path specified incorrectly, PHP can not find the MySQL header file caused by the error prompts.

Workaround.

(1.) See if your system has a MySQL header installed

Find/-name Mysql.h

If there is. Please specify--with-mysql=/with your normal path.

If not. Take a look at the next step.

(2.) Redhat Installation

RPM-IVH mysql-devel-4.1.12-1.i386.rpm

(3.) Ubuntu Installation

Apt-get Install Libmysqlclient15-dev

(4.) The last step of the PHP configuration option to add--WITH-MYSQL=/USR can be.

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. If the PHP configure is missing, you can install the library (Ubuntu)

sudo apt-get install make Bison Flex Gccpatch autoconf Subversion Locate

sudo apt-get install Libxml2-dev libbz2-devlibpcre3-dev libssl-dev zlib1g-dev libmcrypt-dev Libmhash-dev Libmhash2libcurl4-openssl-dev Libpq-dev libpq5 Libsyck0-dev

6. Mcrypt.h not found. Please Reinstalllibmcrypt

Apt-get Install Libmcrypt-dev

Or

Cd/usr/local/src

Wgethttp://softlayer.dl.sourceforge.net/sourceforge/mcrypt/libmcrypt-2.5.8.tar.gz

TAR-ZXVF libmcrypt-2.5.8.tar.gz

cd/usr/local/src/libmcrypt-2.5.8

./configure--prefix=/usr/local

Make

Make install

7. PHP-FPM 5.4.7 How to turn off reboot.

The PHP-FPM in PHP 5.4.7 no longer supports PHP-FPM previously available commands such as/USR/LOCAL/PHP/SBIN/PHP-FPM (Start|stop|reload), which require signal control:

The master process can understand the following signals

INT, TERM immediately terminate QUIT smooth terminate USR1 reopen log file USR2 smooth overload of all worker processes and reload configuration and binary modules

Example:

PHP-FPM off:

Kill-int ' Cat/usr/local/php/var/run/php-fpm.pid '

PHP-FPM reboot:

KILL-USR2 ' Cat/usr/local/php/var/run/php-fpm.pid '

To view the number of PHP-FPM processes:

PS aux | Grep-c PHP-FPM

8. Execute PHP under command line, prompt cannot find command

-bash:/usr/bin/php:no such file ordirectory

Vi/etc/profile

Add one line of configuration to the bottom of the file

Export Path=/usr/local/php/bin: $PATH

Save exit

Source/etc/profile
