nginx 错误:(99:无法分配请求的地址) [英] nginx error: (99: Cannot assign requested address)

问题描述

我正在运行 Ubuntu Hardy 8.04 和 nginx 0.7.65，当我尝试启动我的 nginx 服务器时:

I am running Ubuntu Hardy 8.04 and nginx 0.7.65, and when I try starting my nginx server:

$ sudo /etc/init.d/nginx start

我收到以下错误:

Starting nginx: [emerg]: bind() to IP failed (99: Cannot assign requested address)

其中IP"是我的 IP 地址的占位符.有人知道为什么会发生该错误吗?这是在 EC2 上运行的.

where "IP" is a placeholder for my IP address. Does anybody know why that error might be happening? This is running on EC2.

我的 nginx.conf 文件如下所示:

My nginx.conf file looks like this:

user www-data www-data;
worker_processes  4;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    access_log /usr/local/nginx/logs/access.log;

    sendfile        on;
    tcp_nopush      on;
    tcp_nodelay         on;

    keepalive_timeout  3;

    gzip  on;
    gzip_comp_level 2;
    gzip_proxied any;
    gzip_types  text/plain text/css application/x-javascript text/xml application/xml
    application/xml+rss text/javascript;

    include /usr/local/nginx/sites-enabled/*;

}

我的/usr/local/nginx/sites-enabled/example.com 看起来像:

and my /usr/local/nginx/sites-enabled/example.com looks like:

server {

        listen   IP:80;
        server_name  example.com;
        rewrite ^/(.*) https://example.com/$1 permanent;

       }

server {

        listen   IP:443 default ssl;

        ssl         on;
        ssl_certificate     /etc/ssl/certs/myssl.crt;
        ssl_certificate_key /etc/ssl/private/myssl.key;

        ssl_protocols       SSLv3 TLSv1;
        ssl_ciphers ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP;

        server_name example.com;

        access_log /home/example/example.com/log/access.log;
        error_log /home/example/example.com/log/error.log;

        }

推荐答案

使用 Amazon EC2 和弹性 IP，服务器实际上并不像大多数其他服务器那样知道其 IP.

With Amazon EC2 and elastic IPs, the server doesn't actually know its IP as with most any other server.

所以你需要告诉你的linux允许进程绑定到非本地地址.只需将以下行添加到 /etc/sysctl.conf 文件中:

So you need to tell your linux to allow processes to bind to the non-local address. Just add the following line into /etc/sysctl.conf file:

# allow processes to bind to the non-local address
# (necessary for apache/nginx in Amazon EC2)
net.ipv4.ip_nonlocal_bind = 1

然后通过以下方式重新加载您的 sysctl.conf:

and then reload your sysctl.conf by:

$ sysctl -p/etc/sysctl.conf

重新启动就可以了.
