我不得不在后台运行nginx启动脚本，或者运行时不会返回到shell – 它通过
service nginx start ..或者干脆运行..
/etc/init.d/nginx
直接 我不得不在背景中运行它，然后放弃它..
运行在Ubuntu 14.04.2，Nginx v 1.4.6上
nginx -V给我们：

..和“bash -x nginx restart”返回..

然后什么都没有
CONFIGS：
nginx.conf
# Generic startup file. user www-data developers; #ususally equal to number of CPU's you have. run command "grep processor /proc/cpuinfo | wc -l" to find it worker_processes auto; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; # Keeps the logs free of messages about not being able to bind(). daemon off; events { worker_connections 1024; } http { # rewrite_log on; include mime.types; default_type application/octet-stream; access_log /var/log/nginx/access.log; sendfile on; # tcp_nopush on; keepalive_timeout 3; # tcp_nodelay on; # gzip on; #php max upload limit cannot be larger than this client_max_body_size 13m; fastcgi_buffers 16 16k; fastcgi_buffer_size 32k; index index.php index.html index.htm; # Upstream to abstract backend connection(s) for PHP. upstream php { #this should match value of "listen" directive in php-fpm pool server unix:/var/run/php5-fpm.sock; } include sites-enabled/*; }
任何见解将不胜感激。
初始化脚本，特别是助手start-stop-daemon ，预计它开始将程序默认放在后台。 然而，有人错误地改变了你的nginxconfiguration，以防止它做到这一点：
# Keeps the logs free of messages about not being able to bind(). daemon off;
这部分应该完全删除。 首先，nginx 应该是守护进程。 其次，如果出现无法绑定（）的消息，那不是因为nginx是作为守护进程运行的，这是因为当有人试图启动第二个副本时，nginx已经在运行。
