官方网站下载源码包

http://www.php.net/downloads.php#v5.6.37

找到包下载地址后，复制一下，到linux中通过wget命令直接下载。

wget http://am1.php.net/distributions/php-5.6.37.tar.gz

加压缩源码包

tar -zxvf php-5.6.37.tar.gz

编译PHP5.6

进入解压后的php5.6源码文件夹。

配置编译参数

./configure --prefix=/opt/php/php5.6 \
--with-config-file-path=/opt/php/php5.6/etc \
--enable-inline-optimization --disable-debug \
--disable-rpath --enable-shared --enable-opcache \
--enable-fpm --with-fpm-user=www \
--with-fpm-group=www \
--with-mysql=mysqlnd \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-gettext \
--enable-mbstring \
--with-iconv \
--with-mcrypt \
--with-mhash \
--with-openssl \
--enable-bcmath \
--enable-soap \
--with-libxml-dir \
--enable-pcntl \
--enable-shmop \
--enable-sysvmsg \
--enable-sysvsem \
--enable-sysvshm \
--enable-sockets \
--with-curl --with-zlib \
--enable-zip \
--with-bz2 \
--with-readline \
--without-pear \
--disable-phar \

编译PHP源码，等待编译结束，中途可能会有错误，按着错误提示安装对应的程序要，直接使用yum安装即可。

make
make install

配置PHP服务参数

从源码包中将php.ini-production文件复制到php安装目录下

cp php.ini-production /opt/php/php5.6/etc/php.ini

进入php安装目录设置php-fpm服务

cd /opt/php/php5.6/etc
cp php-fpm.conf.default php-fpm.conf

修改配置文件中的监听端口号和启动用户

## file : php-fpm.conf

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
user = www
group = www

## file : php-fpm.conf

listen = 127.0.0.1:9001

创建php-fpm启动脚本（脚本代码参见下节）,将脚本放到/etc/init.d/php-fpm5.6。
测试一下
添加系统服务

php-fpm服务启动脚本

#! /bin/sh

### BEGIN INIT INFO
# Provides:          php-fpm
# Required-Start:    $remote_fs $network
# Required-Stop:     $remote_fs $network
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: starts php-fpm
# Description:       starts the PHP FastCGI Process Manager daemon
### END INIT INFO

# 通常只需要修改一下prefix地址
prefix=/opt/php/php5.6
