问题：docker docker内nginx 80端口被占用
描述:[root@8f52078ea4e6 config]# nginx
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()
docker容器配置的端口对应关系: 22/tcp, 0.0.0.0:80->80/tcp
解决方案1:用的什么镜像?
如果官方的nginx的话, nginx进程已经启动了, 这时你当然不能再在80上启动另一个
解决方案2:不是很确定，但是和docker的端口映射应该是没关系的，docker的关系映射相当于是再virtual box里面配了一个端口匹配规则，不会占用这个端口的，相当于外部端口转发到内部容器端口里。
所以你这个错误应该是docker内部端口被占了。试一下lsof -i :80看看
以上介绍了“docker docker内nginx 80端口被占用”的问题解答，希望对有需要的网友有所帮助。
