The entire process of installing the ftp server on the CentOS 7 system

After many detours during the installation and configuration process, I will summarize it briefly. Convenient for everyone to learn reference. The installation steps are as follows:

1. Install ftp. I believe this step is simple

# yum -y install ftp vsftpd

View the installation

#rpm -qc vsftpd
/etc/logrotate.d/vsftpd
/etc/pam.d/vsftpd
/etc/vsftpd/ftpusers
/etc/vsftpd/user_list
/etc/vsftpd/vsftpd.conf

2. Server configuration

Create ftp root /ftp/private (there is a puzzle here, if you create a /root/ftp/private directory, you will be prompted 500 OOPS when you log in: cannot change directory: / root/ftp/private such mistakes, now unable to solve, hope to have a friend know explain 1 below), if you create a public directory, you need to create/ftp/open and in/etc vsftpd/vsftpd conf increase anon_root=/ftp/open

#mkdir /ftp


#mkdir /ftp/private

Create a password plaintext file and create two users John, Jack, passwxx, passwyy

#vim /etc/vsftpd/pass.txt


John
passwxx
Jack
passwyy

Create the password DB file from the clear text, and userlist.db is the database of user passwords

#db_load -T -t hash -f /etc/vsftpd/pass.txt \
> /etc/vsftpd/userlist.db

Create vftpd system account ftp_user

#useradd -d /root/ftp/private -s /sbin/nologin ftp_user

Configure user data

# vi/etc/pam.d/vsftpd


// will auth and account All configuration lines are commented out and the following is added: 
authrequiredpam_userdb.so db=/etc/vsftpd/userlist
accountrequiredpam_userdb.so db=/etc/vsftpd/userlist

userlist is/etc vsftpd/userlist db database, but don't add. db suffixes, the system automatically added

In/etc vsftpd/vsftpd conf add 1 under content:

#vim /etc/vsftpd/vsftpd.conf
#anon_root=/ftp/open // If you want to increase 1 Public file directory, comment out virtual_use_local_privs=YES
guest_enable=YES
guest_username=ftp_user
chroot_local_user=YES
allow_writeable_chroot=YES

At the same time will chroot_list_enable=YES，chroot_list_file=/etc/vsftpd/chroot_list Comment out and remove chroot_list_file=/etc/vsftpd/chroot_list
Instead of chroot_list_file=/ftp

chroot_list_enable=YES
# (default follows)
chroot_list_file=/ftp

Start the vsftpd

#systemctl start vsftpd

Set to boot

#rpm -qc vsftpd
/etc/logrotate.d/vsftpd
/etc/pam.d/vsftpd
/etc/vsftpd/ftpusers
/etc/vsftpd/user_list
/etc/vsftpd/vsftpd.conf

0

Check the vsftpd status

#rpm -qc vsftpd
/etc/logrotate.d/vsftpd
/etc/pam.d/vsftpd
/etc/vsftpd/ftpusers
/etc/vsftpd/user_list
/etc/vsftpd/vsftpd.conf

1

The local login

#rpm -qc vsftpd
/etc/logrotate.d/vsftpd
/etc/pam.d/vsftpd
/etc/vsftpd/ftpusers
/etc/vsftpd/user_list
/etc/vsftpd/vsftpd.conf

Others, if you cannot create a file, modify a file, etc., change the relevant directory permissions yourself.
