How to install and configure PHP under Linux

1) This article mainly shares with you how to install and configure PHP under Linux, download the PHP installation package, and choose PHP here. Version 5.6, I hope it can help everyone.

And unzip the PHP installation package

wget cn2.php.net/get/php-5.6.31.tar.gz/from/this/mirror

gzip -d php-5.6.31.tar.gz

tar xvf php-5.6.31.tar

2) Add the www user group and www user (if the user group already exists in the system, there is no need to add the user group)

groupadd www

useradd -g www -s /sbin/nologin -M www

3) Use su super user to log in to Linux and compile PHP parameters

su

#./configure

--prefix=/usr/local/php \

--with-mysql=/usr/local/mysql \

--with-apxs=/usr/local/apache2/bin/apxs \

--prefix specifies the installation path

--with-mysql specifies the mysql path

--with-apxs Specify the apahce path

If an error is reported during the next compilation process, you can call ./configure --help according to the error report to view the compilation parameters, and download and install the corresponding dependency packages;

4) Compile, Install PHP

make

make install

5) Modify Apache's configuration file to support php, and make the following modifications to apache's httpd.conf

In "AddType application/x-gzip .gz .tgz" Add

AddType application/x-httpd-php .php

AddType application/x-httpd-php-source .php5

Add "index.php" to the content in "<IfModule dir_module>", that is, as follows:

<IfModule dir_module>

    DirectoryIndex index.html index.php

</IfModule>

Modify "#ServerName www.example.com:80" For

ServerName 127.0.0.1:80

或

ServerName localhost:80

6) Copy the configuration file in the php-5.6.31 installation package

cp php-5.6.31/php.ini.dist  /usr/local/php/lib/php.ini

If "php.ini.dist" does not exist, you can change "php.ini-development" or Change one of "php.ini-production" to "php.ini.dist" and then execute the above instructions

Change the php.ini file

register_globals = On

7) Test whether the installation is completed

Restart Apache

service apache restart

Write a php file (add it and name it test.php), place it in apache/htdoc, and access it in the browser: http://127.0.0.1/test.php

If the content in the php file can be displayed correctly, the installation is successful;

Quick installation method

You can use the yum tool under Centos and the apt-get tool under Ubuntu , can achieve a quick installation method, the usage is basically the same, here is a demonstration of using yum to install PHP

1) Check whether PHP

rpm -qa php

already exists in the system 2) Install PHP

yum -y install php

3) Check the PHP installation information

chkconfig php on

If the PHP version on the yum source is too low, for example, if you want to install the PHP5.6 version, you can use the following methods:

1) Configure centos epel and remi Source

# Centos 6

rpm -Uvh http://ftp.iij.ad.jp/pub/linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm

#Centos 7

yum install epel-release

rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
