nginx解析php文件时502

fastcgi_fast路径问题

检查下面的配置(服务器配置，/etc/nginx/site-enabled/下配置项，以default为例).

location ~ \.php$ {
        include snippets/fastcgi-php.conf;
    #
    #    # With php5-fpm (or other unix sockets):
        fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
    #    # With php5-cgi (or other tcp sockets):
    #    fastcgi_pass 127.0.0.1:9000;
    }

检查fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;配置，确认/var/run/php/php7.0-fpm.sock存在。 deepin 15.3中，该设置默认为fastcgi_pass unix:/var/run/php7.0-fpm.sock， 而文件php7.0-fpm.sock真实路径为/var/run/php/php7.0-fpm.sock。
