突然我得到下面的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
我什么也得不到。80端口上没有东西
然后我运行如下:
sudo netstat -pan | grep ":80"

我被难住了。我如何调试这个?
我在端口8070上使用带有代理通道的uwsgi。Uwsgi正在运行。Nginx则不然。我使用的是ubuntu 12.4
下面是我的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;
}
}
下面是我在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
首先修改apache监听端口80为8080
在/etc/apache2/ports.conf中包含Apache
Listen 1.2.3.4:80 to 1.2.3.4:8080
sudo service apache2 restart
or
sudo service httpd restart // in case of centos
然后添加nginx作为反向代理服务器，将监听apache端口
server {
listen 1.2.3.4:80;
server_name some.com;
access_log /var/log/nginx/something-access.log;
location / {
proxy_pass http://localhost:8080;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
location ~* ^.+\.(jpg|js|jpeg|png)$ {
root /usr/share/nginx/html/;
}
location /404.html {
root /usr/share/nginx/html/40x.html;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
# put code for static content like js/css/images/fonts
}
修改后重启nginx服务器
sudo service nginx restart
现在所有流量都将由nginx服务器处理，并将所有动态请求发送到apache，静态内容由nginx服务器提供。
对于像缓存这样的高级配置:

我在letsencrypt (certbot)和nginx中遇到了同样的问题，
裁判:https://github.com/certbot/certbot/issues/5486
此错误还没有解决方案
因此，a更改了一个cron为renew(在renew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"
