用Docker实现nginx多端口

一．安装docker

需要阿里的epel源，需要联网

[root@bogon ~]#yum -y install docker

[root@bogon ~]#systemctl start docker

[root@bogon ~]#systemctl enable docker

1. 下载httpd镜像

Docker pull http:2.4.27-alpine     如果镜像本地/root下存放了，可以用docker road < nginx

1. 运行容器并指定端口

[root@localhost ~]# docker run -it -p 8001:80 docker.io/nginx /bin/bash

root@c8931c0b8359:/# nginx

4查看容器状态

[root@localhost ~]# docker container ls     或者 docker ps -a

进入容器里面

[root@localhost ~]# docker attach 9b

root@9b38a1021078:/#

5.在容器安装目录下创建网页

Yum安装地址放在/usr/share/nginx/html

源码安装地址放在/usr/local/nginx/htm

root@c8931c0b8359:/usr/share/nginx/html# ls

50x.html  index.html

root@c8931c0b8359:/usr/share/nginx/html# echo 'welocome to beijing' > index.html

root@c8931c0b8359:/usr/share/nginx/html# [root@localhost ~]#

[root@localhost ~]# curl 192.168.30.24:8001

welocome to beijing

6在容器里可以创建多个端口：8002

[root@localhost ~]# docker run -it -p 8002:80 docker.io/nginx /bin/bash

root@9b38a1021078:/# nginx

root@9b38a1021078:/# [root@localhost ~]#

[root@localhost ~]# docker container ls

[root@localhost ~]# docker attach 9b

root@9b38a1021078:/# cd /usr/share/nginx/html/

root@9b38a1021078:/usr/share/nginx/html# ls

50x.html  index.html

root@9b38a1021078:/usr/share/nginx/html# echo 'welocome to shandong' > index.html

root@9b38a1021078:/usr/share/nginx/html# [root@localhost ~]#

[root@localhost ~]# curl 192.168.30.24:8002

welocome to shandong

[root@localhost ~]# docker ps
