简单安装（通过yum）
- 安装epel-release
<pre>rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm</pre>z - 安装PHP7的rpm源
<pre>rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm</pre> - 安装PHP7
<pre>yum install php70w</pre>
编译安装
- 下载php7
<pre>
wget -O php7.tar.gz http://cn2.php.net/get/php-7.0.4.tar.gz/from/this/mirror
</pre> - 解压php7
<pre>tar -xvf php7.tar.gz</pre> - 进入php目录
<pre>cd php-7.0.4</pre> - 安装依赖包
<pre>
直接复制下面一行（不包括本行）
yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel</pre>
- 编译配置（如果出现错误，基本都是上一步的依赖文件没有安装所致）
嫌麻烦的可以从这一步起参考PHP官方安装说明：http://php.net/manual/zh/install.unix.nginx.php

</pre> - 正式安装
<pre>make && make install</pre> - 配置环境变量
<pre>vi /etc/profile</pre>在末尾追加
<pre>
PATH=$PATH:/usr/local/php/bin
export PATH
</pre>执行命令使得改动立即生效<pre>source /etc/profile</pre> - 配置php-fpm
<pre>
cp php.ini-production /etc/php.ini
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
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm
</pre> - 启动php-fpm
<pre>/etc/init.d/php-fpm start</pre>
