Build FTP file service based on CentOS for your reference. The details are as follows

System requirements: CentOS 7.264-bit operating system

one。 Install VSFTPD

(vsftpd is a FTP server widely used on Linux. According to its [official website] [https://security.appspot.com/vsftpd.html]] [https://security.appspot.com/vsftpd.html]], it is probably the most secure and fast FTP server software under UNIX-like.)

Yum install vsftpd-y

Start VSFTPD (after installation is complete, start the FTP service)

Service vsftpd start

After startup, you can see that the system has [listened for port 21]: the FTP protocol uses port 21 as the service port by default.

Netstat-nltp | grep 21

At this point, visit ftp:// to browse the / var/ftp directory on the machine.

two。 Configure FTP permissions

At present, FTP service login allows anonymous login, and it is impossible to distinguish user access. We need to configure FTP access rights.

The configuration directory of vsftpd is / etc/vsftpd and contains the following configuration files:

Vsftpd.conf configure user list forbidden access to FTP server for main profile ftpusers configure user access control for user_list

Read the above configuration for more information. If you are ready, click next to modify the configuration to set permissions.

Prevent anonymous access and switching the root directory (anonymous access and switching the root directory will bring [security risk] to the server, we turn these two functions off) Edit / etc/vsftpd/vsftpd.conf

# disabling anonymous user anonymous_enable=NO# forbids switching root directory anonymous access allows everyone to upload files to the server without authentication, while allowing switching to the root directory may lead to unauthorized access. Chroot_local_user=YES

Restart the FTP service:

Service vsftpd restart

three。 Create a FTP user

# create a user ftpuseruseradd ftpuser # set the password echo "Password" for the user ftpuser | passwd ftpuser-- stdin

Restrict the user's access to the server only through FTP: restrict user ftpuser to access the server only through FTP and cannot log in directly to the server

Usermod-s / sbin/nologin ftpuser

Assign home directories to users

Create a [home directory] for user ftpuser and agree to:

/ data/ftp is the main directory, which cannot upload files

/ data/ftp/pub files can only be uploaded to this directory

Mkdir-p / data/ftp/pub

Create a login welcome file:

Echo "Welcome to use FTP service." > / data/ftp/welcome.txt

Set access permissions:

Chmod a murw / data/ftp & & chmod 777-R / data/ftp/pub

Set to the user's home directory:

Usermod-d / data/ftp ftpuser

four。 Prepare domain name and certificate (CVM)

To resolve the domain name to the experimental CVM, it will take some time for the domain name to take effect after it is set and resolved. Check whether the domain name is valid through the ping command: if the information returned by the ping command contains the resolved IP address you set, the resolution is successful.

Ping jikexianfeng.xyz

five。 Access the FTP service

Access through Windows Explorer: Windows users can copy the following link to the explorer's address bar to access:

Ftp://ftpuser:xoAEUG5c@118.89.65.22

Access through the FTP client tool:

There are many FTP client tools, and two commonly used ones are recommended:

FTP and SFTP connection client under WinSCP-Windows

FileZilla-Cross-platform FTP client that supports Windows and Mac

After downloading and installing the FTP client, connect using the following credentials:

Host ip: your host ip

User: ftpuser

Password: xoAEUG5c
