1.安装依赖软件库:
yum install -y libxml2-devel libtool* curl-devel libjpeg-devel libpng-devel freetype-devel
2.下载php7源码包进行编译安装
[root@iZ2zef0e6br88incakir9rZ opt]# wget http://cn2.php.net/distributions/php-7.0.14.tar.gz
[root@iZ2zef0e6br88incakir9rZ opt]# tar xf php-7.0.14.tar.gz
[root@iZ2zef0e6br88incakir9rZ opt]# cd php-7.0.14
[root@iZ2zef0e6br88incakir9rZ opt]# ./configure --prefix=/usr/local/php-7.0.14 --enable-fpm --enable-opcache --with-config-file-path=/usr/local/php-7.0.14/etc --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --enable-static --enable-sockets --enable-wddx --enable-zip --enable-calendar --enable-bcmath --enable-soap --with-zlib --with-iconv --with-freetype-dir --with-gd --with-jpeg-dir --with-xmlrpc --enable-mbstring --with-sqlite3 --with-curl --enable-ftp --with-mcrypt --with-openssl --disable-safe-mode --with-gettext
报错:configure: error: mcrypt.h not found. Please reinstall libmcrypt.
解决:下载libmcrypt源码库
wget https://svwh.dl.sourceforge.net/project/mcrypt/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz
编译安装:
make && make install
3.配置文件php.ini
[PHP]
engine = On #是否启用php解析引擎

4.进程服务的配置文件php-fpm，把php-fpm引入www.conf文件中的配置
[root@iZ2zef0e6br88incakir9rZ etc]# cat /usr/local/php-7.0.14/etc/php-fpm.conf
include=/usr/local/php-7.0.14/etc/php-fpm.d/*.conf
[root@iZ2zef0e6br88incakir9rZ etc]# vim /usr/local/php-7.0.14/etc/php-fpm.d/www.conf
[global] 全局定义
log_level = notice 错误级别. 可用级别为: alert（必须立即处理）, error（错误情况）, warning（警告情况）, notice（一般重要信息）, debug（调试信息）. 默认: notice.
error_log=/data/log/php/error_php-fpm7.log 错误日志文件保存路径
[www] 定义www的pool
user = www 启动进程的帐户
group = www 启动进程组
listen = 127.0.0.1:9999 fpm监听端口，即nginx中php处理的地址
pm = dynamic pm的模式,分为static|dynamic两种
pm.max_children = 50 子进程最大数
pm.start_servers = 10 启动时的进程数
pm.min_spare_servers = 10 保证空闲进程数最小值，如果空闲进程小于此值，则创建新的子进程
pm.max_spare_servers = 50 保证空闲进程数最大值，如果空闲进程大于此值，此进行清理
5.复制服务控制脚本php-fpm到系统服务脚本目录:
cp /opt/php-7.0.14/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm7 && chmod 755 /etc/init.d/php-fpm7
设置php7开启启动:
chkconfig --add php-fpm7
chkconfig php-fpm7 on
启动php：
service php-fpm7 start
