yum安装php7.0
安装PHP的版本为7.0，具体版本可以更改
按照系统更新yum源，我的是centos7，所以我运行下面的代码！
CentOS/RHEL 7.x:
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
如果是centos6，那么执行以下代码：
CentOS/RHEL 6.x:
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm
然后就可以直接yum安装php7.0了，可以安装的拓展如下：
yum install php70w-common php70w-fpm php70w-opcache php70w-gd php70w-mysqlnd php70w-mbstring php70w-pecl-redis php70w-pecl-memcached php70w-devel
就这一条命令，就可以安装了下面的拓展了！
php-api, php-bz2, php-calendar, php-ctype, php-curl, php-date, php-exif, php-fileinfo, php-filter, php-ftp, php-gettext, php-gmp, php-hash, php-iconv, php-json, php-libxml, php-openssl, php-pcre, php-pecl-Fileinfo, php-pecl-phar, php-pecl-zip, php-reflection, php-session, php-shmop, php-simplexml, php-sockets, php-spl, php-tokenizer, php-zend-abi, php-zip, php-zlib
激动吧？别急，还有更牛的！一般都要安装memcached，gd,mysql,等等是吧？
