下面进行编译安装PHP7.0，编译安装最头疼的就是因为某些类库没有安装而报错，所以编译前请确保以下包已安装。
$ 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
先去官网下载PHP7.0即可，官方地址：
$ tar xvf php-7.0.10.tar.gz $ cd php-7.0.10
进行编译前配置，我添加了一些常用的扩展。
$ ./configure \ --prefix=/usr/local/php \ --with-curl \ --with-freetype-dir \ --with-gd \ --with-gettext \ --with-iconv-dir \ --with-kerberos \ --with-libdir=lib64 \ --with-libxml-dir \ --with-mysqli \ --with-openssl \ --with-pcre-regex \ --with-pdo-mysql \ --with-pdo-sqlite \ --with-pear \ --with-png-dir \ --with-xmlrpc \ --with-xsl \ --with-zlib \ --enable-fpm \ --enable-bcmath \ --enable-libxml \ --enable-inline-optimization \ --enable-gd-native-ttf \ --enable-mbregex \ --enable-mbstring \ --enable-opcache \ --enable-pcntl \ --enable-shmop \ --enable-soap \ --enable-sockets \ --enable-sysvsem \ --enable-xml \ --enable-zip
然后进行编译和安装
$ make $ make install
完结。
