用户访问FTP服务器
lftp是一个功能强大的下载工具，支持FTP协议，llftp类似shell，具有命令补全、允许多个后台任务执行功能(书签、排队、镜像、断点续传)等
安装：
yum -y install lftp
实例一：使用lftp从FTP服务器下载hosts 文件与pub目录到当前目录
[root@Linux ~]# lftp 47.93.209.191 lftp 47.93.209.191:~> ls -rw-r--r-- 1 0 0 213 Oct 17 06:31 hosts drwxr-xr-x 2 0 0 4096 Jun 09 2021 pub lftp 47.93.209.191:/> get hosts 213 bytes transferred lftp 47.93.209.191:/> ls -rw-r--r-- 1 0 0 213 Oct 17 06:31 hosts drwxr-xr-x 2 0 0 4096 Jun 09 2021 pub lftp 47.93.209.191:/> mirror pub/ Total: 1 directory, 0 files, 0 symlinks lftp 47.93.209.191:/> exit
注意：lftp下载文件后在退出ftp服务时，可查看下载的文件
[root@Linux ~]# ll total 1656048 -rw-r--r-- 1 root root 213 Oct 17 14:31 hosts drwxr-xr-x 2 root root 4096 Oct 17 14:44 pub
ls命令查看所有文件与目录，get命令下载文件，mirror命令下载目录
使用wget工具也可以从ftp服务器下载文件
实例二、添加 -O 参数，将其重命名为 a.txt ,并放到/var/tmp目录下
[root@Linux test]# wget ftp://47.93.209.191/hosts -O /root/test/a.txt --2022-10-17 14:52:34-- ftp://47.93.209.191/hosts => ‘/root/test/a.txt’ Connecting to 47.93.209.191:21... connected. Logging in as anonymous ... Logged in! ==> SYST ... done. ==> PWD ... done. ==> TYPE I ... done. ==> CWD not needed. ==> SIZE hosts ... 213 ==> PASV ... done. ==> RETR hosts ... Error in server response, closing control connection. Retrying.
错误：Error in server response, closing control connection.
Retrying.
解决办法：
1.#vim /etc/vsftpd/vsftpd.conf
2.添加：pasv_promiscuous=YES
3.保存后退出
4.[root@Linux test]# systemctl restart vsftpd
重新下载文件即可：
[root@Linux test]# wget ftp://47.93.209.191/hosts -O /root/test/a.txt --2022-10-17 14:56:14-- ftp://47.93.209.191/hosts => ‘/root/test/a.txt’ Connecting to 47.93.209.191:21... connected. Logging in as anonymous ... Logged in! ==> SYST ... done. ==> PWD ... done. ==> TYPE I ... done. ==> CWD not needed. ==> SIZE hosts ... 213 ==> PASV ... done. ==> RETR hosts ... done. Length: 213 (unauthoritative) 100%[===================================================>] 213 --.-K/s in 0s 2022-10-17 14:56:14 (52.0 MB/s) - ‘/root/test/a.txt’ saved [213]
在/root/test/目录下查看文件a.txt
添加 "-P" 参数，可以指定存放目录
[root@Linux test]# wegt ftp://47.93.209.191/hosts -P /root/test -bash: wegt: command not found [root@Linux test]# wget ftp://47.93.209.191/hosts -P /root/test --2022-10-17 15:01:00-- ftp://47.93.209.191/hosts => ‘/root/test/hosts’ Connecting to 47.93.209.191:21... connected. Logging in as anonymous ... Logged in! ==> SYST ... done. ==> PWD ... done. ==> TYPE I ... done. ==> CWD not needed. ==> SIZE hosts ... 213 ==> PASV ... done. ==> RETR hosts ... done. Length: 213 (unauthoritative) 100%[===================================================>] 213 --.-K/s in 0s 2022-10-17 15:01:00 (40.2 MB/s) - ‘/root/test/hosts’ saved [213]
添加 “-o”参数，可以将整个执行过程的信息存入某一文件，不在终端中显示
[root@Linux test]# wget ftp://47.93.209.191/hosts -O /root/test/a.txt
添加 “-q”参数，不显示任何信息
# wget ftp://47.93.209.191/hosts -q
添加 "-m" 参数，可下载目录
# wget ftp://47.93.209.191/pub -m
本地用户访问ftp服务器，创建普通用户alice,并在用户的/home目录下创建file,密码
设置为123，在客户端使用lftp链接到ftp服务器中的alice用户
[root@Linux test]# useradd alice [root@Linux test]# touch /home/alice/file [root@Linux test]# echo "123" | passwd alice [root@Linux test]# lftp alice@47.93.209.191 Password: lftp alice@47.93.209.191:~> ls ls: Login failed: 530 Login incorrect.
出现以上错误：lftp alice@47.93.209.191:~> put /etc/services
put: Login failed: 530 Login incorrect.
解决方法：
检查vsftpd.conf文件(如：/etc/vsftpd/vsftpd.conf)，查找userlist_enable项 注释或设置为no
