Install vsftpd FTP server on CentOS 7

# yum install vsftpd

# vim /etc/vsftpd/vsftpd.conf

anonymous_enable=NO

local_enable=YES

chroot_local_user=YES

### add these lines to the end of vsftpd.conf. This is to configure to use passive mode. Otherwise, you would see "Failed to retrieve directory listing. Connection timeout".
pasv_enable=YES
pasv_min_port=12000
pasv_max_port=12100
pasv_address=<Public IP of your instance>
pasv_addr_resolve=NO

# systemctl enable vsftpd
# systemctl restart vsftpd

# useradd ftp-user1 -m -c 'ftp user' -s /sbin/nologin

# usermod -s /sbin/nologin ftp-user1

# chmod a-w /home/ftp-user1

Note: if you see 500 OOPS: vsftpd: refusing to run with writable root inside chroot (), make sure the user's home directory is not writable.

# passwd ftp-user1

# firewall-cmd --permanent --zone=public --add-port=20-21/tcp
# firewall-cmd --permanent --zone=public --add-port=12000-12100/tcp
# firewall-cmd --reload
# firewall-cmd --zone=public --list-all

Note: make sure you do open these ports on your Amazon EC2 instance security group as well.

# setsebool -P ftp_home_dir 1
# getsebool -a | grep ftp

ftp_home_dir --> on
