nginx服务器访问时没解析PHP，直接下载php文件

location ~ \.php$ {
        try_files $uri =404; #增加
        fastcgi_split_path_info ^(.+.php)(/.+)$; #反注释
        ## NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
        #
        ## With php5-cgi alone:
        #fastcgi_pass 127.0.0.1:9000;
        ## With php5-fpm:
        fastcgi_pass unix:/var/run/php5-fpm.sock; #反注释
        fastcgi_index index.php; #反注释
        include fastcgi_params; #反注释
