[英]Unable to start nginx on Ubuntu on any port even though only port 80 is in use
我无法在Ubuntu16.04上启动Nginx。
当我运行sudo /etc/init.d/nginx start
,出现错误。
(env) agaidis@Computer:~$ sudo /etc/init.d/nginx start
[....] Starting nginx (via systemctl): nginx.serviceJob for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.
failed!
当我通过致电深入查看错误消息时,
sudo systemctl status nginx.service
我收到以下反馈:
(env) agaidis@Computer:~/www$ sudo systemctl status nginx.service

我一直在按照该网站上的步骤进行操作,以使nginx和gunicorn正常运行。 我一直在网上寻找解决问题的方法,但没有任何效果。
我在不是nginx的端口80上运行了另一台服务器,因此我在/etc/nginx/sited-available/default
, /etc/nginx/sited-available/<name of flask app>
切换了端口和/etc/nginx/sited-enabled/<name of flask app>
都可以在端口8888上侦听和响应。我也尝试了其他端口号。 不幸的是,这似乎根本没有帮助。
我的/etc/nginx/sited-available/default
文件看起来像这样:

我的/etc/nginx/sited-enabled/<name of flask app>
和/etc/nginx/sited-available/<name of flask app>
文件如下所示:
server {
location / {
proxy_pass http://localhost:8888;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
location /static {
alias /home/agaidis/www/<name of flask app>/static/;
}
}
在尝试启动服务器之前,我尝试过的其他操作包括sudo apt-get update
和sudo apt-get upgrade nginx
。
无论如何,有没有在不停止当前服务器在端口80上运行的情况下解决问题的方法? 任何帮助都将不胜感激:)
我加了listen 8080;
到我的/etc/nginx/sited-available/<name of flask app>
文件的顶部。 因此,它变成:
server {
listen 8080;
location / {
proxy_pass http://localhost:8888;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
location /static {
alias /home/agaidis/www/<name of flask app>/static/;
}
}
那解决了我的问题。
