下面進行編譯安裝PHP7.0，編譯安裝最頭疼的就是因爲某些類庫沒有安裝而報錯，所以編譯前請確保以下包已安裝。
$ yum groupinstall "development tools"
$ yum install -y gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype \
freetype-devel libpng libpng-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel \
glib2 glib2-devel bzip2 bzip2-devel ncurses curl curl-devel openssl-devel gdbm-devel db4-devel \
libXpm-devel libX11-devel gd-devel gmp-devel readline-devel libxslt-devel expat-devel xmlrpc-c xmlrpc-c-devel先去官網下載PHP7.0即可，官方地址：
$ tar xvf php-7.0.10.tar.gz
$ cd php-7.0.10進行編譯前配置，我添加了一些常用的擴展。
$ ./configure \
