#配置
cd /usr/local/etc/
cp php-fpm.conf.default php-fpm.conf
#然后在编辑php-fpm.conf配置文件
;最后一行改成如下
include=/usr/local/etc/php-fpm.d/*.conf

cd php-fpm.d/
cp www.conf.default www.conf
#编辑www.conf文件，将user和group改成和nginx.conf中的user和group一致
user = nginx
group = nginx
/usr/local/sbin/php-fpm
vi /etc/rc.local
添加 /usr/local/sbin/php-fpm 

#修改nginx的配置文件，支持php文件的解析，找到location的添加位置，在后面添加下面这个location

 location ~ \.php$ {
                        root /var/www; #指定php的根目录
                        fastcgi_pass 127.0.0.1:9000;#php-fpm的默认端口是9000

#php7安装后没有安装mysqli扩展的话：

#安装mysqli扩展

1、到php文件ext下的mysqli      cd /usr/local/php-7.1.5/ext/mysqli   

2、在mysqli文件夹下执行　/usr/local/php/bin/phpize  生成configure文件

3、在mysqli文件夹下执行 ./configure --with-php-config=/usr/local/php/bin/php-config --with-mysqli=/usr/bin/mysql_config     

4、make

5、make install
6、修改php.ini 打开extension=mysqli

 

附：

找不到mysql_config的话可能是没有安装mysql-devel
yum install mysql-devel
