Detailed tutorial on installing PHP5.6.30 service under CentOS7.0

About php-fpm

nginx itself It cannot handle PHP. It is just a web server. When a request is received, if it is a PHP request, it will be sent to the PHP interpreter for processing and the result will be returned to the client.

nginx generally sends the request to the fastcgi management process for processing. The fascgi management process selects the cgi sub-process processing result and returns it to nginx.

PHP-FPM is a PHP FastCGI manager, only for PHP.

PHP has written php-fpm into the PHP source code core after 5.3.3. So there is no need to download it separately.

Get the PHP download address

Why choose version 5.6.30? Because it is learning, not research. It is true that 7.0 has added many new features of PHP, and the performance has also been improved. If you are doing research, you can do some research. I will talk about the 7.0 version and how to switch between various PHP versions later.

Open the official website of php: http://php.net/, view the version list of php

Right-click, copy the link address, and run it on the remote host Log in and download the software (I chose Australia’s host mirror to download)

# wget http://au1.php.net/get/php-5.6.30.tar.gz/from/this/mirror

What is downloaded is a mirror file, change it to the file name we need

#mv mirror php-5.6.30.tar.gz#tar zxvf php-5.6.30.tar.gz#cd php-5.6.30

Configure installation

Enter the directory, we need to configure the installation directory to /usr/local/php/ during installation

#./configure 
--prefix=/usr/local/php 
--with-curl 
--with-freetype-dir 
--with-gd 
--with-gettext 
--with-iconv-dir 
--with-kerberos 
--with-libdir=lib64 
--with-libxml-dir 
--with-MySQL 
--with-mysqli 
--with-openssl 
--with-pcre-regex 
--with-pdo-mysql 
--with-pdo-sqlite 
--with-pear
 --with-png-dir 
--with-xmlrpc 
--with-xsl 
--with-zlib 
--enable-fpm 
--enable-bcmath 
--enable-libxml 
--enable-inline-optimization 
--enable-gd-native-ttf 
--enable-mbregex 
--enable-mbstring 
--enable-opcache 
--enable-pcntl 
--enable-shmop 
--enable-soap 
--enable-sockets 
--enable-sysvsem 
--enable-xml 
--enable-zip

During the configuration process The following error may be reported

Error 1:

xml2-config not found. 
Please check your libxml2 installation.

Solution

Install libxml2 related components

#yum install libxml2#yum install libxml2-devel -y

Error 2:

Please reinstall the libcurl 
distribution - 
easy.h 
should be in
 <curl-dir>/include/curl/

Install curl related components

#yum install curl curl-devel

Error 3:

configure: error: png.h not found.

Install libpng related components

#yum install libpng#yum install libpng-devel

Error 4:

freetype-config not found.

Install freetype related components

#yum install freetype-devel

Error 5:

xslt-config not found. Please reinstall the libxslt >= 1.1.0 distribution

Install libxslt related components

#yum install libxslt-devel

Okay, when we see the following sentence, it means that your php has been configured!

Next we only need to compile and install to complete the installation of php

#make && make install

Seeing this sentence indicates that the installation is complete!

To be on the safe side, let’s make a test to see if it is really successful.

Configure related php.ini configuration

First we need to configure the php.ini file

The installation directory has 2 files: php.ini-development and php.ini-production

php.ini-production Use the online version

php.ini-development Use the development version

We choose development for configuration

# cp php.ini-development /usr/local/php/lib/php.ini

php-fpm configuration

Copy the php-fpm configuration file

#cp -R ./sapi/fpm/php-fpm.conf /usr/local/php/etc/php-fpm.conf

Copy the enable file

#cp -R ./sapi/fpm/php-fpm /etc/init.d/php-fpm（已弃用，详细的见注1）

Start

#/etc/init.d/php-fpm

Check whether php is started successfully

#ps aux | grep php

Seeing these indicates that your php It has been started successfully!

Restart and shut down

#kill -9 进程号
#/etc/init.d/php-fpm

Configure Nginx to support PHP

Enter the nginx main directory, /usr/local/nginx;

#cd /usr/local/nginx

Enter the configuration directory

#cd conf

Nginx supports PHP. You need to modify nginx.conf

#vim nginx.conf

and open the following code to let Nginx support PHP in the server code segment.

After modification, this code changes to the red part indicating that our host directory is /usr/www. You need to modify fastcgi_param SCRIPT_FILENAME to point to the corresponding directory:

Set the home directory to /usr/www.

Comment out the root line and add a new line: root /usr/www;

Save and exit.

According to the explanation in the Nginx chapter, we restart the Nginx service.

#/etc/init.d/nginx restart

If you have not configured it according to our method in Nginx, you can restart the Nginx service as follows

# /usr/local/nginx/sbin/nginx -s reload

Restart successfully! Next we add a new file in the /usr/www directory.

#vim /usr/www/phpinfo.php

Insert the following content

<?php phpinfo(); ?>

Open http://remoteip/phpinfo.php

in the browser

看到这个页面，恭喜你，你的PHP已经安装配置完成。你可以在这个页面看到所有php依赖的组件，下一节我将和大家详细讲解一下这个页面，如果对本节有什么疑问的，欢迎在评论区和我交流讨论，有留言必回。^_^ 

注

设置php开机自启动与开启php服务便捷方式

上面的方法中，我在拷贝php-fpm的服务时出了问题，不应该直接将php-fpm的可执行文件拷贝到/etc/init.d/目录下去，应该将php给我们准备好的init.d.php-fpm。

#cp ./sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

将php-fpm服务添加到chkconfig列表

#chkconfig --add php-fpm

设置开机自启动

#chkconfig php-fpm on

以后重启和停止php的方式为

#service php-fpm start
#service php-fpm stop
#service php-fpm restart
#service php-fpm reload

上面是我的问题，请大家及时更正。
