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
- 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
- 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
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9b38a1021078 docker.io/nginx "/bin/bash" 18 seconds ago Up 16 seconds 0.0.0.0:8002->80/tcp stoic_goldwasser
c8931c0b8359 docker.io/nginx "/bin/bash" 13 minutes ago Up 13 minutes 0.0.0.0:8001->80/tcp kind_booth
[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
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9b38a1021078 docker.io/nginx "/bin/bash" 2 minutes ago Up 2 minutes 0.0.0.0:8002->80/tcp stoic_goldwasser
c8931c0b8359 docker.io/nginx "/bin/bash" 15 minutes ago Up 15 minutes 0.0.0.0:8001->80/tcp kind_booth
