cd sapi/fpm
cp init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm
chkconfig --add php-fpm
chkconfig php-fpm on
cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf
cd /usr/local/php7/etc/php-fpm.d
cp www.conf.default www.conf 启动服务
#启动服务
/etc/init.d/php-fpm start
#添加环境变量,添加到最后一行
vim /etc/profile

#修改 nginx 配置文件
vim /usr/local/nginx/conf/nginx.conf
#配置参考如下
location / {
root html;
index index.php index.html index.htm;
}
location ~ \.php${
root html;
fastcgi _pass 127.0.0.1:9000; #php-fpm的IP与端口
fastcgi_index index.php;
#fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_scritp_name;
include fastcgi.conf #加载Fast-CGI参数文件
}
#完成后重载（启）nginx
/usr/local/nginx/sbin/nginx -s reload 创建测试文件
vim /usr/local/nginx/html/index.php
<?php
$i=30;
echo $i;
?> 访问显示值为30，则安装成功，撒花！
