我知道这个主题有多种不同的形式,但我无法解决我的问题。如果我运行service nginx restart
,nginx 会失败并显示以下日志:
2015/03/14 08:36:42 [emerg] 9400#0: bind() to 0.0.0.0:80 failed (98: Address already in use)

2015/03/14 08:36:42 [emerg] 9400#0: still could not bind()
我只有一个配置正在加载sites-enabled
。当我运行时:
$ grep -slir "listen 80"
$ sites-available/default
它表明default
配置已经监听 80,但是这并不重要,因为它不在sites-enabled
。
$ ps ax -o pid,ppid,%cpu,vsz,wchan,command|egrep '(nginx|PID)'
PID PPID %CPU VSZ WCHAN COMMAND

以下显示了netstat
正在使用的端口:

我想知道这个 bind() 错误是否因为我的配置而发生。你知道我可能做错了什么吗?我使用的是 nginx/1.4.6 (Ubuntu)。任何帮助都将不胜感激。
答案1
尝试停止 nginx:
service nginx stop
检查 nginx 是否仍在运行:
ps ax | grep nginx
如果仍在运行,则终止该进程:
kill -p PID
检查nginx状态,不会运行:
ps ax | grep nginx
然后重新开始:
service nginx start
解决相同问题后,这对我有用。
答案2
我遇到了类似的问题。
这对我有用:
sudo fuser -k 80/tcp
然后:
service nginx restart
我不知道原因,但我的答案在这里找到: https://easyengine.io/tutorials/nginx/troubleshooting/emerg-bind-failed-98-address-already-in-use/
此外,以下是此错误消息如何/何时出现的背景故事: https://serverfault.com/a/939888/399723
答案3
根据您的netstat
输出,nginx 本身仍在端口 80 上运行。
在尝试重新启动之前,请验证您的配置nginx -t
并修复错误。
答案4
首先,我们必须检查端口 80 上有多少个服务在运行。要检查这一点,您可以运行以下命令:
sudo netstat -plant | grep 80
这将向您显示哪个服务正在监听端口 80,然后您可以决定是否要按原样使用该服务或改用 Nginx。
如果是 Apache,您需要决定是否要使用 Apache 或 Nginx。
如果您只想使用 Nginx,则需要先停止 Apache:
sudo systemctl stop apache2 && sudo systemctl start nginx
