1. Installation

Use the domestic Sohu mirror station to download php5.6 and install it Package, execute:

wget  http://mirrors.sohu.com/php/php-5.6.2.tar.gz

Before installation, first install the software packages that php5.6 depends on when compiling. As follows:

yum -y install gcc gcc-c++ libxml2 libxml2-devel

Next, unzip and install php5.6, first perform the decompression:

tar -xf php-5.6.2.tar.gz

Then enter the decompression directory of php5.6, now start configuring php5.6, use the following command:

cd php-5.6.2

The function of --enable-fpm in the above command is to enable the fastcgi function of php, that is, to enable the php-fpm function, –with -mysql=/usr/local/mysql is to enable PHP to support mysql. /usr/local/mysql is the installation path of the mysql database. Note that if the following error is reported here:

Error configure: error: Cannot find MySQL header files under /usr/local/mysql, you can try the following solution:

--with-mysql=/usr/local/mysql，

Change it to

--with-mysql或--with-mysql=/usr

–enable-mbstring means to enable the mbstring module. The main function of the mbstring module is to detect and conversion encoding, providing corresponding string functions for multi-byte operations. Currently, the internal encoding of PHP only supports ISO-8859-*, EUC-JP, and UTF-8. Other encoding languages ​​cannot be displayed correctly on the PHP program, so we need to enable the mbstring module.

After this step is successful, you will see the following interface:

Next, compile and install. First execute the make command. After success, you will see the following interface. ：

Just execute the make install command again. At this time, you can use php -v to view the version information after successful installation.

2. Configuration

After the installation is successful, do the basic configuration operations. After the above installation, there is no php in the /usr/local/lib directory .ini file. First copy the template provided by the php installation file, as follows:

cp php.ini-production /usr/local/lib/php.ini

At this time, nginx in the server environment still does not support it. For PHP, requests related to PHP must be processed through fastcgi. PHP needs the php-fpm component to support it. This is the command used when configuring PHP - enable-fpm.

After the php-fpm function is enabled, php-fpm also needs to be configured. In fact, the php-fpm configuration file has already provided us with a configuration file template when installing php. The template is /usr/local/etc/php-fpm.conf.default. Make a copy of this file and rename it to php-fpm.conf, as follows:

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

In order to start php-fpm as a service. We need to copy the /sapi/fpm/init.d.php-fpm file in the PHP installation directory. As follows:

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

At this time, the php-fpm file does not have execution permission. Grant execution permissions to php-fpm, start php-fpm, and execute the following command:

chmod a x /etc/init.d/php-fpm

/etc/init.d/php- fpm start

Check after starting:

Port 9000 is the default listening port of php-fpm.

# Next to configure nginx to support it to support PHP, as follows:

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;

}

Then create a new file index.php (/usr/local/nginx/html/index.php) in the root directory of nginx website with the following content:

e2d0e752df2c971bca1fcef6e50119b4

Go to the /usr/local/nginx/sbin/ directory, execute ./nginx to start nginx, and then enter the server ip/index.php in the browser , if you see the following information, it proves that the installation has been started successfully:
