docker安装nginx之后无法访问
今天安装完nginx 之后，容器可以正常启动，但是在Linux 与外面浏览器无法访问，但是进入容器内部，可以正常访问nginx
代码示例
# 运行nginx docker run --name nginx-test -p 8081:80 -d nginx # 查看容器id docker ps
查看容器内部ip地址
docker inspect e59d18a16a78 | grep IPAddress
"SecondaryIPAddresses": null,
"IPAddress": "172.17.0.2",
"IPAddress": "172.17.0.2",
curl 172.17.0.2 这个时候直接就链接不上
进入容器内部可以正常访问
[root@localhost vmuser]# docker exec -it e59d18a16a78 bash
root@e59d18a16a78:/# curl 127.0.0.1

解决方案：
- 查看是否关闭防火墙
systemctl status firewald.service
- 查看是否有暴漏ip地址
1）lsof -i :8080 查看8080端口被哪个进程占用 2）netstat -lnp|grep 8080 查看8080端口被哪个进程占用 3）ss -nlap | grep 8080 查看8080端口被哪个进程占用
- 有可能是linux 版本与docker 版本不兼容（此方法解决）
# uname -a
# lsb_release -a
Distributor ID: CentOS

# docker version

升级版本内核
#升级linux内核版本，升级所有包同时也升级软件和系统内核 [root@localhost ~]# yum update -y
