Linux_配置认证访问FTP服务

【RHEL8】—FTPserver；【Centos8】—FTPclient

！！！测试环境我们首关闭防火墙和selinux（FTPserver和FTPclient都需要）

[root@localhost ~]# systemctl stop firewalld

[root@localhost ~]# systemctl disable firewalld

[root@localhost ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

[root@localhost ~]# reboot

一、配置FTP服务端

1、查看一下服务端IP

[root@FTPserver ~]# ip addr

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    inet 127.0.0.1/8 scope host lo

       valid_lft forever preferred_lft forever

    inet6 ::1/128 scope host

       valid_lft forever preferred_lft forever

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

    link/ether 00:0c:29:fa:c0:f0 brd ff:ff:ff:ff:ff:ff

    inet 192.168.121.10/24 brd 192.168.121.255 scope global noprefixroute eth0

       valid_lft forever preferred_lft forever

    inet6 fe80::a101:bf00:d10e:9788/64 scope link noprefixroute

       valid_lft forever preferred_lft forever

2、安装vsftpd服务

 //首先查看是否安装vsftpd服务

[root@FTPserver ~]# rpm -qa | grep vsftpd

 //安装vsftpd服务

[root@FTPserver ~]# yum install -y vsftpd

............

Running transaction

  Preparing        :                                                                                                                                                   1/1

  Installing       : vsftpd-3.0.3-28.el8.x86_64                                                                                                                        1/1

  Running scriptlet: vsftpd-3.0.3-28.el8.x86_64                                                                                                                        1/1

  Verifying        : vsftpd-3.0.3-28.el8.x86_64                                                                                                                        1/1

Installed products updated.

Installed:

  vsftpd-3.0.3-28.el8.x86_64

Complete!

3、启动vsftpd服务

[root@FTPserver ~]# systemctl start vsftpd

[root@FTPserver ~]# systemctl enable vsftpd

Created symlink /etc/systemd/system/multi-user.target.wants/vsftpd.service → /usr/lib/systemd/system/vsftpd.service.

 //查看vsftpd状态及端口

[root@FTPserver ~]# systemctl status vsftpd

● vsftpd.service - Vsftpd ftp daemon

   Loaded: loaded (/usr/lib/systemd/system/vsftpd.service; enabled; vendor preset: disabled)

           └─14612 /usr/sbin/vsftpd /etc/vsftpd/vsftpd.conf

Aug 23 15:12:55 FTPserver systemd[1]: Starting Vsftpd ftp daemon...

Aug 23 15:12:55 FTPserver systemd[1]: Started Vsftpd ftp daemon.

[root@FTPserver ~]# ss -antlp

State           Recv-Q           Send-Q                      Local Address:Port                     Peer Address:Port

LISTEN          0                128                               0.0.0.0:22                            0.0.0.0:*              users:(("sshd",pid=1020,fd=4))

LISTEN          0                32                                      *:21                                  *:*              users:(("vsftpd",pid=14612,fd=3))

LISTEN          0                128                                  [::]:22                               [::]:*              users:(("sshd",pid=1020,fd=6))

4、创建可登陆的用户lisi

[root@FTPserver ~]# useradd lisi

[root@FTPserver ~]# echo "123" |passwd --stdin lisi

Changing password for user lisi.

passwd: all authentication tokens updated successfully.

5、切换至普通用户，创建可上传、可下载的文件

[root@FTPserver ~]# su - lisi

[lisi@FTPserver ~]$ mkdir upload

[lisi@FTPserver ~]$ touch lisifile.txt

[lisi@FTPserver ~]$ echo "this is my ftp file" > lisifile.txt

6、设置文件的权限

[root@FTPserver ~]# chmod u-w /home/lisi/

[root@FTPserver ~]# chmod -R 700 /home/lisi/upload/

7、修改/etc/vsftpd/vsftpd.conf文件

[root@FTPserver ~]# vim /etc/vsftpd/vsftpd.conf

..........

anonymous_enable=NO

local_enable=YES

write_enable=YES

local_umask=022

dirmessage_enable=YES

xferlog_enable=YES

connect_from_port_20=YES

xferlog_std_format=YES

idle_session_timeout=600           //取消改行前面的注释

data_connection_timeout=120          //取消注释

ftpd_banner=Welcome to blah FTP service.     //取消注释

listen=NO

listen_ipv6=YES

pam_service_name=vsftpd

userlist_enable=YES

8、重启vsftpd服务

[root@FTPserver ~]# systemctl restart vsftpd

[root@FTPserver ~]# ss -antpl

State           Recv-Q           Send-Q                      Local Address:Port                     Peer Address:Port

LISTEN          0                128                               0.0.0.0:22                            0.0.0.0:*              users:(("sshd",pid=1020,fd=4))

LISTEN          0                32                                      *:21                                  *:*              users:(("vsftpd",pid=14765,fd=3))

LISTEN          0                128                                  [::]:22                               [::]:*              users:(("sshd",pid=1020,fd=6))

FTP服务端到这就简单配置完成！

二、FTP客户端配置

1、安装ftp客户端工具

 //首先查看是否安装ftp工具

[root@FTPclient ~]# rpm -qa | grep ftp

 //安装Ftp客户端工具

[root@FTPclient ~]# yum install -y ftp

...........

Running transaction

  Preparing        :                                                                                                                                                   1/1

  Installing       : ftp-0.17-78.el8.x86_64                                                                                                                            1/1

  Running scriptlet: ftp-0.17-78.el8.x86_64                                                                                                                            1/1

  Verifying        : ftp-0.17-78.el8.x86_64                                                                                                                            1/1

Installed:

  ftp-0.17-78.el8.x86_64

Complete!

2、客户端连接服务端，进行测试

 //首先准备上传的文件

[root@FTPclient ~]# touch upfile

[root@FTPclient ~]# echo "test file" >upfile 

 //连接服务端

[root@FTPclient ~]# ftp 192.168.121.10
