10.配置LDAP客户端
在classroom.example.com上已经部署了一台LDAP认证服务器,按以下要求将你的系统加入到该LDAP服务中,并使用Kerberos认证用户密码:该LDAP认证服务的Base DN为:dc=example,dc=com该LDAP认证服务的LDAP Server为:classroom.example.com密码认证服务的Kerberos Realm为:EXAMPLE.COM (域控的林)密码认证服务的Kerberos KDC为:classroom.example.com密码认证服务的Kerberos Admin Server为:classroom.example.com认证的绘画连接需要使用TLS加密,加密所用证书请在此下载http://classroom.example.com/pub/example-ca.crt

tab补齐 [root@server0 ~]# systemctl restart sssd.service [root@server0 ~]# systemctl enable sssd[root@server0 ~]# systemctl status sssd.service
另2:文本界面
[root@server0 ~]# yum install authconfig-gtk.x86_64 sssd krb5-workstation.x86_64 -y[root@server0 ~]# authconfig-tui
[root@server0 ~]# cd /etc/openldap/cacerts/[root@server0 cacerts]# wget http://classroom.example.com/pub/example-ca.crt[root@server0 cacerts]# systemctl restart sssd[root@server0 cacerts]# systemctl enable sssd[root@server0 cacerts]# systemctl status sssd[root@server0 ~]# authconfig-tui 记得重新查看下,
验证:(如果没有重启再查看) (多重启几次sssd服务)[root@server0 ~]# su - ldapuser0su: warning: cannot change directory to /home/guests/ldapuser0: No such file or directorymkdir: cannot create directory '/home/guests': Permission denied-bash-4.2$ -bash-4.2$ -bash-4.2$ 说明LDAP配置成功 , ldapuser0 用户是在LDAP网络上的,不在本地
11.配置LDAP用户家目录自动挂载
请使用LDAP服务器上的用户ldapuser0登陆系统,并满足以下要求:
ldapuser0用户的家目录路径为/home/guests/ldapuser0
ldapuser0用户登陆后,家目录会自动挂载到classroom.example.com服务通过nfs服务到处的/home/guests/ldapuser0
[root@server0 ~]# yum install autofs.x86_64 -y[root@server0 ~]# showmount -e classroom.example.com Export list for classroom.example.com:/home/guests 172.25.0.0/255.255.0.0 (LDAP网络共享的目录)[root@server0 ~]# rpm -ql autofs/etc/auto.master/etc/auto.misc[root@server0 ~]# vim /etc/auto.master/misc /etc/auto.misc 这行下面添加 (存在)/home/guests /etc/auto.guests (添加)监控的目标(本地) 监控的条件[root@server0 ~]# cat /etc/auto.misccd -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom 文件系统类型 [root@server0 ~]# vim /etc/auto.guests (新文件)* -fstype=nfs classroom.example.com:/home/guests/& *会根据&变化 &:匹配所有 (网络上的目录) [root@server0 ~]# systemctl restart autofs (root下生成/home/guests/ldapuser0)[root@server0 ~]# systemctl enable autofs[root@server0 ~]# systemctl status autofs
[root@server0 ~]# su - ldapuser0 成功切换目录,证明2个题都做对了[ldapuser0@server0 ~]$ ll /home/guests/drwx------. 5 ldapuser0 ldapuser0 101 Sep 29 18:26 ldapuser0[ldapuser0@server0 ~]$ df -h ldapuser0 用户,以及家目录不在本地,而在LDAP网络上
