Nginx 无法启动(地址已被使用) [英] Nginx will not start (Address already in use)

问题描述

我的 nginx 有问题.我尝试了不同的解决方案，但对我来说没有任何效果.这是我的错误:

I have a problem with nginx. I tried different solutions, but for me nothing work. That is my error:

4 root@BANANAS ~ # sudo service nginx restart                                :(
Restarting nginx: nginx: [emerg] bind() to [::]:443 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:443 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:443 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:443 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:443 failed (98: Address already in use)
nginx: [emerg] still could not bind()
nginx.

你能帮我吗?

推荐答案

可能其他进程正在使用指定端口:

sudo netstat -tulpn

获取已经使用443的进程的PID，并用kill命令发送信号.

Get the PID of the process that already using 443. And send signal with kill command.

sudo kill -2 <PID>

sudo service nginx restart

或者你可以这样做:

sudo fuser -k 443/tcp

确保不要使用旧语法:

server {
    listen :80;
    listen [::]:80;
}

上面的语法会导致

nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)

正确的语法:

server {
    listen 80;
    listen [::]:80 ipv6only=on;
}

或

server {
    listen [::]:80;
}

以上两种语法都可以实现相同的目的，同时监听 ipv4 和 ipv6.

Both above syntax will achieve the same thing, listening on both ipv4 and ipv6.
