问题描述
突然间,我得到了以下nginx错误
* Restarting nginx
* Stopping nginx nginx
...done.
* Starting nginx nginx
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()
...done.
...done.
如果我跑
lsof -i :80 or sudo fuser -k 80/tcp
我一无所获。 80端口没有任何东西
然后我运行以下:
sudo netstat -pan | grep ":80"
tcp 0 0 127.0.0.1:8070 0.0.0.0:* LISTEN 15056/uwsgi

我很难过。
怎么调试?
我正在使用uwsgi
代理传递端口8070.uwsgi正在运行。 Nginx不是。我使用的是ubuntu 12.4
以下是我的nginx conf文件的相关部分
upstream uwsgi_frontend {
server 127.0.0.1:8070;
}
server {
listen 80;
server_name 127.0.0.1;
location = /favicon.ico {
log_not_found off;
}
location / {
include uwsgi_params;
uwsgi_buffering off;
uwsgi_pass 127.0.0.1:8070;
}
}
这是我在ubuntu 12.04上安装nginx的方法
nginx=stable;add-apt-repository ppa:nginx/$nginx;
apt-get update
apt get install nginx-full
最佳解决方案
[::]:80
是一个ipv6地址。
如果您的nginx配置正在侦听端口80以及端口[::]:80
,则可能导致此错误。
我在默认的sites-available文件中有以下内容:
listen 80;
listen [::]:80 default_server;
您可以通过将ipv6only=on
添加到[::]:80
来解决此问题,如下所示:
listen 80;
listen [::]:80 ipv6only=on default_server;
有关更多信息,请参阅:
http://forum.linode.com/viewtopic.php?t=8580
http://wiki.nginx.org/HttpCoreModule#listen
次佳解决方案
我通过运行sudo apachectl stop
来解决这个问题 – 结果是apache在后台运行并阻止nginx在所需的端口上启动。
在ubuntu上运行sudo /etc/init.d/apache2 stop
第三种解决方案
我发现了以前从未有过的问题。
我只需要删除/etc/nginx/sites-available/default
。然后它奏效了。
我的conf在/etc/nginx/default
。
第四种方案
我的情况不同,我不得不杀死运行Nginx重新启动它。
代替
sudo systemctl restart nginx
我不得不使用:
sudo pkill -f nginx
sudo systemctl start nginx
第五种方案
我也得到了同样的错误。
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
当我在浏览器中键入localhost时,我就得到了
It works!
这是此服务器的默认网页。
Web服务器软件正在运行,但尚未添加任何内容。而不是nginx欢迎页面,apache2在同一个端口上运行,
-
找到apache2 ports.conf文件
sudo /etc/apache2/ports.conf
-
更改
80
以外的端口,我将其设为70
-
保存文件
-
重启你的系统
它也适用于您,如果您在浏览器中键入localhost,您将获得nginx欢迎页面
第六种方案
尝试执行此命令
sudo fuser -k 443/tcp
service nginx restart
第七种方案
我在letsencrypt(certbot)和nginx中遇到了同样的问题,
ref:https://github.com/certbot/certbot/issues/5486
此错误还没有解决方案
因此,更新了更新的cron(续订后重新加载)(使用certbot的建议)
-- in /etc/cron.d/certbot
from
0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(3600))' && certbot -q renew
to
0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(3600))' && certbot -q renew --pre-hook "service nginx stop" --post-hook "service nginx start"

第八种方案
我的问题是我有重叠的监听指令。我已经设法通过运行找出重叠的指令
grep -r listen /etc/nginx/*
两个文件正在同一个端口上侦听:
/etc/nginx/conf.d/default.conf: listen 80;
/etc/nginx/sites-enabled/default.conf: listen 80;
