我知道这个话题以各种不同的forms存在，但是我在解决我的问题上遇到了麻烦。 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: bind() to 0.0.0.0:80 failed (98: Address already in use) 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: bind() to 0.0.0.0:80 failed (98: Address already in use) 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configuration加载在sites-enabled 。 当我运行：
$ grep -slir "listen 80" $ sites-available/default
它显示defaultconfiguration有监听80，但这不应该因为它不在sites-enabled 。
$ ps ax -o pid,ppid,%cpu,vsz,wchan,command|egrep '(nginx|PID)' PID PPID %CPU VSZ WCHAN COMMAND 9468 1 0.0 97188 sigsus nginx: master process /usr/sbin/nginx 9471 9468 0.0 97328 ep_pol nginx: worker process 9472 9468 0.0 97368 ep_pol nginx: worker process 9693 9641 0.0 9448 pipe_w egrep --color=auto (nginx|PID)
这是一个netstat显示什么端口正在使用：
$ netstat -tulpn Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 1300/master tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 9468/nginx tcp 0 0 0.0.0.0:2812 0.0.0.0:* LISTEN 5980/monit tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN 1174/mysqld tcp 0 0 127.0.0.1:11211 0.0.0.0:* LISTEN 1155/memcached tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 9468/nginx tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1113/sshd tcp6 0 0 :::25 :::* LISTEN 1300/master tcp6 0 0 :::9000 :::* LISTEN 9106/hhvm tcp6 0 0 :::22 :::* LISTEN 1113/sshd udp 0 0 127.0.0.1:11211 0.0.0.0:* 1155/memcached
这里是我的完整configuration在sites-enabled （在那里唯一）：

我想知道是否这个bind（）错误是由于我的configuration。 任何想法我可能做错了什么？ 我正在使用nginx / 1.4.6（Ubuntu）。 任何帮助将不胜感激。
尝试停止nginx：
service nginx stop
检查仍在运行的nginx：
ps ax | grep nginx
如果还在运行，杀死进程：
kill -p PID
检查nginx状态，不会运行：
ps ax | grep nginx
然后做一个干净的开始：
service nginx start
这同样的问题后为我工作。
根据你的netstat输出，nginx本身仍然在80端口上运行。
在尝试重新启动之前，请使用nginx -tvalidation您的configuration并修复错误。
