环境
1：下载PHP7.0.2的安装包解压，编译，安装:
$ cd /usr/src/ $ wget http://cn2.php.net/distributions/php-7.0.2.tar.gz $ tar -xzxvf php-7.0.2.tar.gz $ cd php-7.0.2
1.1编译前检查
请检查是否安装了gcc ,没有的话执行yum install gcc
检查是否安装了libxml2 ,没有的话执行yum install libxml2
检查是否安装了libxml2-devel,没有的话执行yum install libxml2-devel
注：因为改为用nginx了，所以编译参数中的--with-apxs2=/usr/bin/apxs去掉了，如果要配置apache用，安装PHP前，请先安装apache。*
2：编译参数配置
复制代码 代码如下:"./configure" "--prefix=/usr/local/php" "--with-pdo-pgsql" "--with-zlib-dir" "--with-freetype-dir" "--enable-mbstring" "--with-libxml-dir=/usr" "--enable-soap" "--enable-calendar" "--with-curl" "--with-mcrypt" "--with-gd" "--with-pgsql" "--disable-rpath" "--enable-inline-optimization" "--with-bz2" "--with-zlib" "--enable-sockets" "--enable-sysvsem" "--enable-sysvshm" "--enable-pcntl" "--enable-mbregex" "--enable-exif" "--enable-bcmath" "--with-mhash" "--enable-zip" "--with-pcre-regex" "--with-pdo-mysql" "--with-mysqli" "--with-jpeg-dir=/usr" "--with-png-dir=/usr" "--enable-gd-native-ttf" "--with-openssl" "--with-fpm-user=www-data" "--with-fpm-group=www-data" "--with-libdir=/lib/x86_64-linux-gnu/" "--enable-ftp" "--with-gettext" "--with-xmlrpc" "--with-xsl" "--enable-opcache" "--enable-fpm" "--with-iconv" "--with-xpm-dir=/usr"
3：错误集合

4：编译
make clean && make && make install
5：PHP配置
5.1安装完成后，我们要把源码包中的配置文件复制到PHP安装目录下，源码包中有两个配置 php.ini-development php.ini-production ，看名字就知道，一个是开发环境，一个是生产环境，我们这里就复制开发环境的
cp php.ini-development /usr/local/php/lib/php.ini
5.2另外还需要设置环境变量 ：修改/etc/profile文件使其永久性生效，并对所有系统用户生效，在文件末尾加上如下两行代码
PATH=$PATH:/usr/local/php/binexport PATH
5.3 然后执行生效命令
source /etc/profile
5.4查看PHP版本信息
php -v
6：配置PHP-fpm
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.confcp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.confcp /usr/src/php-7.0.2/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpmchmod +x /etc/init.d/php-fpm
6.1 启动php-fpm:
/etc/init.d/php-fpm start
6.2 如果出现错误：ERROR: [pool www] cannot get uid for user "www-data"
则新建www-data 用户组：
groupadd www-datauseradd -g www-data www-data
6.3 重启php-fpm
/etc/init.d/php-fpm restart
