Setting SFTP user access directory permissions under Linux

First, create a new user, and set the directory, prohibit Shell login

Useradd-m-d/home/wwwroot/licnlt-s/usr/sbin/nologin LICNLT

Nologin to confirm the location in advance, usually under/usr/sbin or/sbin (you can view the Nologin configuration of sshd in/etc/passwd)

Second, set the user password

passwd LICNLT

Third, set the user directory owner to root

Chown root:root/home/wwwroot/licnlt/    #目录只能由root所有chmod 755/home/wwwroot/licnlt            #目录不可以有群组写入权限

　　

Iv. Modification of/etc/ssh/sshd_config files

#注释掉这行 #subsystem      sftp    /usr/libexec/openssh/sftp-server# add Subsystem sftp internal-sftp # At the end of the configuration file     Specifies that the Internal-sftpmatch user LICNLT #匹配用户 with the system comes with the SFTP service                     , and if multiple groups are to be matched, separate the groups with commas CHROOTDIRECTORY/HOME/WWWROOT/LICNLT /         #用chroot将指定用户的根目录, meaning of chroot

V. Restart the SSH service

Service sshd Restart

Six, the user login after entering the/HOME/WWWROOT/LICNLT is the user root directory, the root directory is unable to write, so first use root under/home/wwwroot/licnlt/new www directory, and set permissions 777

Mkdir/home/wwwroot/licnlt/www

Modify Directory Owners and permissions

Chown Licnlt:licnlt/home/wwwroot/licnlt/wwwchmod 777/home/wwwroot/licnlt/www
