FTP server is used to transfer file between computers over network. In this tutorial I will guide you how to setup ftp server on CentOS. This guide contains configuration steps for both ftp and vsftp as well as user creation. In this article I have used VSFTP package which is secure and less vulnerable
Configure FTP Server
Step #1: First update your repository and install VSFTPD package on server.
# yum check-update # yum install vsftpd -y
Step #2: After installing you will need to edit /etc/vsftpd/vsftpd.conf file which is the main configuration file for VSFTPD. Please take backup vsftpd.conf file before making any changes.
# mv /etc/vsftpd/vsftpd.conf /etc/vsftpd/vsftpd.conf.org
Now open and edit file like below.
Find this line anonymous_enable=YES ( Line no : 12 ) and change value to NO to disable anonymous FTP access.
# vim /etc/vsftpd/vsftpd.conf anonymous_enable=NO
Uncomment the below line ( Line no : 100 ) to restrict users to their home directory.
chroot_local_user=YES
Enable passive mode and allow chroot writable.
allow_writeable_chroot=YES pasv_enable=Yes pasv_min_port=40000 pasv_max_port=40100
Step #3: Now restart vsftpd service.
# service vsftpd restart
Step #4: Allow FTP service in firewall to allow ftp ports.
# iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT # iptables -A INPUT -p tcp -m tcp --dport 21 -j ACCEPT
Step #5: Setup SEinux to allow ftp access to the users home directories .
# setsebool -P ftp_home_dir on
Step 6: Now create an User for ftp access. Here /sbin/nologin shell is used to prevent shell access to the server .
# useradd -m sagar -s /sbin/nologin # passwd sagar
Now user sagar can able to login ftp on port 21.
