安装PHP

1、下载源码包程序

# mkdir /tmp/php_build

# cd /tmp/php_build

# wget http://cn2.php.net/distributions/php-7.2.9.tar.xz　　##有其他版本，这是比较老的版本了

2、安装依赖

# yum install -y gcc-c++ libxml2-devel libxml2-devel libcurl-devel libcurl-devel openssl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel

3、创建用户和组

# groupadd -r www

# useradd -s /usr/sbin/nologin -r -M -N www

4、编译安装

# tar Jxvf php-7.2.9.tar.xz -C /usr/local/

# cd /usr/local/php-7.2.9

# /configure

   --prefix=/usr/local/php-7.2.9

   --with-config-file-path=/usr/local/php-7.2.9/etc

   --bindir=/usr/local/php-7.2.9/bin

   --sbindir=/usr/local/php-7.2.9/sbin

   --enable-fpm

   --with-fpm-user=www

   --with-fpm-group=www

   --enable-mysqlnd

   --with-mysqli=mysqlnd

   --with-pdo-mysql=mysqlnd

   --with-iconv-dir

   --with-freetype-dir=/usr/local/freetype

   --with-jpeg-dir

   --with-png-dir

   --with-zlib

   --with-libxml-dir=/usr

   --enable-xml

   --disable-rpath

   --enable-bcmath

   --enable-shmop

   --enable-sysvsem

   --enable-inline-optimization

   --with-curl

   --enable-mbregex

   --enable-mbstring

   --with-gd

   --with-openssl

   --enable-pcntl

   --enable-sockets

   --with-mhash

   --with-xmlrpc

   --enable-zip

   --enable-soap

   --with-gettext

   --disable-fileinfo

   --enable-opcache

   # make -j `grep processor /proc/cpuinfo | wc -l`

   # make install　　#安装完成后会生成/usr/local/php-7.2.9路径

　#后面根据需要修改PHP监听方式就可以了，一种是sock，一种是端口

　#vim /usr/local/php-7.2.12/etc/php-fpm.d/www.conf 

listen = /usr/local/php-7.2.9/var/run/php-7.2.9.sock
或listen = 0.0.0.0:9000;

   #启动命令路径，执行后会有一个PHP主进程很若干个子进程

   #/usr/local/php-7.2.9/sbin/php-fpm
