Enable the ftp service in centos, and enable the ftp service in centos

If you need to install the ftp service to access linux through ftp, vsftpd is a better FTP server in Linux.

1. Check and install vsftp

1 // check whether vsftpd 2 rpm-qa is installed | grep vsftpd3 // if not, install vsftpd4 yum-y install vsftpd5 chkconfig vsftpd on

Ii. Edit vsftp configuration items

Configure to enable the virtual account (only ftp login, not system login) and set the Access Directory

1 vim/etc/vsftpd. conf 2 anonymous_enable = NO // set not to allow anonymous access 3 local_enable = YES // set local users to access. 4 chroot_list_enable = YES // the user cannot leave the home directory 5 ascii_upload_enable = YES 6 ascii_download_enable = YES // set the file name that supports ASCII mode upload and download 7 pam_service_name = vsftpd // PAM Authentication. PAM will be based on/etc/pam. d/vsftpd for authentication 8 9 // manually add 10 guest_enable = YES // set to enable the virtual User Function 11 12 user_config_dir =/etc/vsftpd/vuser_conf // set the virtual user's personal vsftp centOS FTP service file storage path 13 // perform authentication 14 chroot_list_file =/etc/vsftpd/vuser_passwd.txt15 16 local_root = // set access directory not configured default is/var/ftp

3. Install the Berkeley DB tool (for file databases, we use files to store the account and password of virtual users)

yum install db4 db4-utils

4. Create the User Password text/etc/vsftpd/vuser_passwd.txt. The odd line is the user name, and the even line is the password

1 vim /etc/vsftpd/vuser_passwd.txt
2 test3 123456

5. Generate the database file of the virtual user account and password and associate it with the data db File

1 db_load -T -t hash -f /etc/vsftpd/vuser_passwd.txt /etc/vsftpd/vuser_passwd.db

Edit the authentication file/etc/pam. d/vsftpd,All commentsDrop the original statement and add the following two more statements:

1 auth required pam_userdb.so db=/etc/vsftpd/vuser_passwd2 account required pam_userdb.so db=/etc/vsftpd/vuser_passwd

 

6. Restart the vsftpd service

1 service vsftpd restart

Finally, create an ftp connection to the ftp server
