Nginx挂起重启

我必须在后台运行nginx启动脚本,否则它在运行时不会返回shell – 它通过以下任一方式执行此操作

service nginx start

..或只是运行..

/etc/init.d/nginx

..直接.我必须在后台运行它然后否认它..

在Ubuntu 14.04.2上运行,Nginx v 1.4.6

nginx -V给了我们：

nginx version: nginx/1.4.6 (Ubuntu)

..和“bash -x nginx restart”返回..

..然后什么也没有.

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/*;
}

任何见解都将非常感激. 最佳答案 init脚本,特别是helper start-stop-daemon,默认情况下它开始将程序放在后台.但是,有人错误地改变了你的nginx配置,以防止它这样做：

# Keeps the logs free of messages about not being able to bind().
daemon     off;

应完全删除此部分.首先,nginx应该是daemonizing.其次,如果出现关于无法绑定()的消息,那不是因为nginx作为守护进程运行,这是因为当有人试图启动第二个副本时,nginx已经在运行.
