sftp配置多个用户权限的问题

groupadd group1

chmod 0755 /test/
useradd -g group1 -d /test/backend/ -M test_backend
usermod -s /sbin/nologin test_backend
passwd test_backend
xxxxxxxx

useradd -g group1 -d /test/api/ -M test_api
usermod -s /sbin/nologin test_api
passwd test_api
xxxxxx

useradd -g group1 -d /test/business/ -M test_business
usermod -s /sbin/nologin test_business
passwd test_business
xxxxxx

vi /etc/ssh/sshd_config

UseDNS no
AddressFamily inet
SyslogFacility AUTHPRIV
PermitRootLogin yes
PasswordAuthentication yes

# override default of no subsystems
# Subsystem sftp /usr/libexec/openssh/sftp-server
Subsystem sftp internal-sftp

Match User test_backend
ChrootDirectory /test/backend
X11Forwarding no
AllowTcpForwarding no
ForceCommand internal-sftp
Match User test_api
ChrootDirectory /test/api
X11Forwarding no
AllowTcpForwarding no
ForceCommand internal-sftp
Match User test_business
ChrootDirectory /test/business
X11Forwarding no
AllowTcpForwarding no
ForceCommand internal-sftp

systemctl restart sshd

这里有几点

1、主目录的所有者必须为root

即 chown root:root /test

2、权限为chmod 755 /test

3、要想让sftp修改子目录，只能创建子目录来设置权限

mkdir /test/api/project01

chown test_api:group1 /test/api/project01

chmod 755 /test/api/project01
