Linux-install and configure vsftpd in CentOS,-centosvsftpd

Bad environment:CentOS 1, 7.0

There is not much gossip. Let's get started with the subject.

Step 1: Install vsftpd and run it on the terminal

yum -y install vsftpd

Test whether the installation is successful

service vsftpd start

If the prompt is:

Starting vsftpd for vsftpd:    [ok]

Success.

Step 2: edit the vsftpd configuration file

vi /etc/vsftpd/vsftpd.conf

Clear the file and add the following content:

listen=YES background=YES anonymous_enable=NO local_enable=YES write_enable=YES local_umask=022 anon_upload_enable=NO anon_mkdir_write_enable=NO dirmessage_enable=YES xferlog_enable=YES connect_from_port_20=YES chown_uploads=NO xferlog_file=/var/log/vsftpd.log xferlog_std_format=YES async_abor_enable=YES ascii_upload_enable=YES ascii_download_enable=YES ftpd_banner=Welcome to hao32 FTP servers pam_service_name=vsftpd chroot_local_user=NO chroot_list_enable=YES chroot_list_file=/etc/vsftpd/vsftpd.chroot_list 

Step 3: run the following command on the terminal

touch /etc/vsftpd/vsftpd.chroot_list service vsftpd start 

If the following sentence appears:

Starting vsftpd for vsftpd: [OK]

The statement is successful. If not, use this statement:

/etc/rc.d/init.d/xinetd restart 

Step 4: add an ftp user

By default, ftp uses the System user. Now we add the user csuldw, pointing to the directory/home/csuldw, Permission isnologinThat is, the shell permission is not given and ftp is not affected.

useradd csuldw -d /home/csuldw -s /sbin/nologin 

If:
Useradd: warning: the home directory already exists.
Not copying any file from skel directory into it.

Ignore this. It just tells you that the directory you direct to already exists, which does not affect
You can also use other grouping methods to set the group of directories and their files, as follows:

chown -R csuldw.csuldw /home/csuldw

Set the password of the user csuldw and set it by yourself. The command is as follows:

passwd csuldw

Add the user csuldw/etc/vsftpd/vsftpd.chroot_listIn this way, the user can log on normally and cannot jump out of his directory

echo 'csuldw' >> /etc/vsftpd/vsftpd.chroot_list service vsftpd restart 

Step 5: Test

Configuration complete! Test Login

Ftp host: Enter the Server IP address as follows:ftp 192.168.0.1
Ftp user: Csuldw
Ftp Password: You just set

Note: It is best to disable the firewall when performing FTP operations.

service iptables stop

By default, the root account is not allowed to upload files.
Implement root permission upload:

Vi/etc/vsftpd/user_list # root comment out vi/etc/vsftpd/ftpusers # root comment out

Client Software upload error:

553 cocould not create file.

Cause: No write permission.
Solution:

chmod 777 /var/ftp/pub
