Linux under the PHP source code installation Steps ____linux

First, download the PHP source code

Download Address: http://cn.php.net/downloads.php II, installation

1. Move the downloaded binary package to the/usr/local directory and unzip the package

Tar zxvf php-7.1.4.tar.gz

2, into the decompression of the PHP folder under/usr/local/php-7.1.4, installation dependencies, compile installation
Yum Install LIBXML2 Libxml2-devel

./configure--prefix=/usr/local/php--with-zlib--enable-zip--with-openssl--enable-fpm- With-libdir=lib64--without-pear--disable-phar

Make

Make test (you can allow the makes test command to detect compilation problems after compilation)

Make install

3, PHP configuration

#php的配置文件为 php.ini

Cp/usr/local/php-7.1.4/php.ini-production/usr/local/php/lib/php.ini

#使得另一种方法来管理服务:
cp/usr/local/php-7.1.4/sapi/fpm/php-fpm/etc/init.d/php-fpm

#添加执行权限

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

#php-FPM configuration file

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

Cp/usr/local/php/etc/php-fpm.d/www.conf.default/usr/local/php/etc/php-fpm.d/www.conf

Modify the maximum number of PHP-FPM processes according to machine configuration, which is limited to/usr/local/php/etc/php-fpm.d/www.conf
Use Netstat-napo |grep "PHP-FPM" | Wc-l look at the current number of fastcgi processes, if the number is close to the upper limit of the configuration in conf, you need to increase the number of processes.
But also can not endlessly increase, depending on the server memory, you can php-fpm the number of child processes to 100 or more, in 4G memory server 200 on it.
Pm.max_children = 200

Pm.start_servers = 10

Pm.min_spare_servers = 8

Pm.max_spare_servers = 12

4. Set environment variable

Vi/etc/profile

After opening, add the following configuration at the bottom of the document:

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

: wq! save Exit, execute the following command to make the change take effect

Source/etc/profile

5, start the PHP test

#启动

/etc/init.d/php-fpm

#测试php

Cd/usr/local/nginx/html

VI test.php

Add the following:
<?php
Echo Phpinfo ();
?>

: wq! save exit.

Browser input: http://10.62.32.123/test.php

If it appears: PHP Version 7.1.4 interface, showing PHP detailed configuration of the interface, indicating that the installation is correct

6, PHP restart, stop

PHP 7.1.4 Source code has been embedded in the PHP-FPM, just to configure the time to add the compilation parameters.
The compilation parameters about PHP-FPM have a –enable-fpm–with-fpm-user=www–with-fpm-group=www–with-libevent-dir=libevent location.
However, the php-fpm in the PHP 7.1.4 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:
SIGINT, Sigterm immediately terminated.
Sigquit Smooth Termination
SIGUSR1 Reopen the log file
SIGUSR2 smooth overload of all worker processes and reload configuration and binary modules

Example:
PHP-FPM off:
Kill-sigint ' Cat/usr/local/php/var/run/php-fpm.pid '
PHP-FPM reboot:
KILL-SIGUSR2 ' Cat/usr/local/php/var/run/php-fpm.pid '

To view the number of PHP-FPM processes:
PS aux | Grep-c PHP-FPM
Netstat-anpo | grep "php-cgi" | Wc-l
Netstat-anop | grep "PHP-FPM" | Wc-l
