Reprint: http://zyjustin9.iteye.com/blog/2178943

One. Installation
1. Install the VSFTPD with the Apt-get tool:

Java code

1. $ sudo apt-get install vsftpd

2. Check if the FTP port is already open

Java code

1. $ netstat-tnl

or enter "ftp://server IP" directly in the browser.

Commands to turn on, stop, and restart the VSFTPD service:

XML code

1. Service VSFTPD Start | Stop | Restart

Two. Configuration
1. Modify the configuration file

Java code

1. $ sudo vi/etc/vsftpd.conf

Main configuration:

XML code

2. listen=YES # Server monitoring
4. local_enable=YES # allows local users to access
6. write_enable=YES # is allowed to upload files, do not open will be reported 550 permission denied
8. anonymous_enable=No # Anonymous access allowed, default does not open,
10. #anon_upload_enable=Yes # anonymous upload allowed, default is no
12. #anon_mkdir_write_enable=YES # Anonymous Create folder allows

Permission settings for the user to access the directory:
In the default configuration, a local user can switch to a different directory using the CD command after logging in to FTP, which poses a security risk to the system. You can control the user to switch directories by using the following three configuration files.

XML code

1. chroot_local_user=YES To specify whether users in the user list file are allowed to switch to the parent directory.  The default value is No.
2. chroot_list_enable=YES # Sets whether the user list file specified by the Chroot_list_file configuration item is enabled.  The default value is No.
3. Chroot_list_file=/etc/vsftpd.chroot_list
4. #禁用的列表名单, in the form of a single user, that specifies a user list file that controls which users can switch to the parent directory of the user's home directory.

The following effects can be achieved by pairing:

XML code

2. (1). When chroot_list_enable=Yes,chroot_local_user=Yes, users listed in the/etc/vsftpd.chroot_list file can switch to a different directory  , users who are not listed in the file cannot switch to a different directory.
4. (2). When chroot_list_enable=YES,chroot_local_user=No, users listed in the/etc/vsftpd.chroot_list file cannot switch to a different directory  , users who are not listed in the file can switch to a different directory.
6. (3). When chroot_list_enable=No,chroot_local_user=Yes, all users cannot switch to a different directory.
8. (4). When chroot_list_enable=No,chroot_local_user=No, all users can switch to a different directory.
