nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)错误解决方法

今天在ubuntu10.04上面安装nginx，安装完成之后尝试启动nginx，使用命令：

代码如下	复制代码
sudo /etc/init.d/nginx start

结果发现启动不了，出现如下错误提示

hankcs@ubuntu:~$ sudo /etc/init.d/nginx start
[sudo] password for hankcs:
* 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()

问题描述：地址已被使用。可能nginx服务卡死了，导致端口占用，出现此错误。

解决方法：

首先用lsof:80看下80端口被什么程序占用。lsof返回结果如下：

代码如下

复制代码

hankcs@ubuntu:~$ netstat -ntpl

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 127.0.0.1:53            0.0.0.0:*               LISTEN      -
tcp        0      0 127.0.0.1:631           0.0.0.0:*               LISTEN      -
hankcs@ubuntu:~$ killall -9 nginx

nginx：没有发现操作

nginx的配置文件

代码如下

复制代码

hankcs@ubuntu:~$ sudo gedit /etc/nginx/sites-available/default

修改这一段：

listen 80;
listen [::]:80 default_server;

为

listen 80;
listen [::]:80 ipv6only=on default_server;

然后启动nginx，完美解决！

如果你发现操作我们可以如下操作

发现是nginx程序，所以我们把nginx服务k掉，重新启动服务。。命令如下:

代码如下

复制代码

kill -9 3274
kill -9 3547

service nginx start

补充一个80占用解决办法

原因: 端口 80 端口被占用，用 “lsof -i:80" 命令查看一下是什么程序占用了80端口，我的结果显示是 80 端口被 apache 占用
[root@localhost html]# lsof -i:80
COMMAND PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
httpd   1203   root    4u IPv6   8514      0t0 TCP *:http (LISTEN)

httpd   1873 apache    4u IPv6   8514      0t0 TCP *:http (LISTEN)
httpd   1874 apache    4u IPv6   8514      0t0 TCP *:http (LISTEN)

httpd   1876 apache    4u IPv6   8514      0t0 TCP *:http (LISTEN)
httpd   1877 apache    4u IPv6   8514      0t0 TCP *:http (LISTEN) 解决办法: 依照自己情况适当处理，我的是把 apache 停掉了并直接卸载了（因为 apache 我已经不用了），重新启动了 nginx
