一、ftp介绍

ftp分为主动模式（PORT）和被动模式(PASV)。主动模式使用20和21端口，其中20为数据端口，21为控制端口。被动模式使用21控制端口和一个其他随机端口作数据端口。

二、检查本地docker状态

[root@node ~]# systemctl status docker

三、下载vsftpd镜像

[root@node ~]# docker pull fauria/vsftpd
Using default tag: latest
latest: Pulling from fauria/vsftpd
75f829a71a1c: Pull complete 
a1a6b490d7c7: Pull complete

Status: Downloaded newer image for fauria/vsftpd:latest
docker.io/fauria/vsftpd:latest

四、创建vsftpd容器

1.创建数据目录

[root@node ~]# mkdir -p /data/ftp/data  && mkdir -p /data/ftp/log  && chmod -R 777 /data/ftp

2.创建vsftpd容器

docker run -d \
--name vsftpd   \
--restart=always \
-v /data/ftp/data/:/home/vsftpd \
-v  /data/ftp/log/:/var/log/vsftpd/ \
-p 20:20 -p 21:21 -p 20000:20000 \
-e FTP_USER=admin \
-e FTP_PASS=admin \
-e PASV_MIN_PORT=20000 \
-e PASV_MAX_PORT=20000 \
-e PASV_ADDRESS=192.168.3.166 \
-e LOG_STDOUT=1 \
fauria/vsftpd

3.查看vsftpd容器状态

[root@node ftp]# docker ps
CONTAINER ID   IMAGE                                                    COMMAND                  CREATED          STATUS                 PORTS                                                                                          NAMES
fce7b8fc2279   fauria/vsftpd                                            "/usr/sbin/run-vsftp…"   38 seconds ago   Up 36 seconds          0.0.0.0:20-21->20-21/tcp, :::20-21->20-21/tcp, 0.0.0.0:20000->20000/tcp, :::20000->20000/tcp   vsftpd

五、linux客户端访问ftp

1.安装ftp客户端软件

yum install -y ftp 

2.登录ftp

[root@node ftp]# ftp 192.168.3.166
Connected to 192.168.3.166 (192.168.3.166).
220 (vsFTPd 3.0.2)
Name (192.168.3.166:root): admin
331 Please specify the password.
Password:
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> ls
227 Entering Passive Mode (192,168,3,166,78,32).
150 Here comes the directory listing.
226 Directory send OK.
ftp> 

六、web页面访问ftp

ftp://192.168.3.166/

七、上传文件

1.在挂载数据目录上传文件

[root@node admin]# mkdir test it linux
[root@node admin]# 
[root@node admin]# ls
it  linux  test
[root@node admin]# cd linux/
[root@node linux]# touch file100

2.查看ftp上文件
