01 NIS-server

1.准备工作

vim /etc/hosts

172.25.0.101 storage-1.example.com

172.25.0.100 storage-2.example.com

useradd nis-user1

useradd nis-user2

passwd nis-user1

passwd nis-user2

2.安装软件

yum install ypserv -y

3.设置NIS域名

add the line:

DefaultDependencies=no

in the [Unit] section of /usr/lib/systemd/system/rhel-domainname.service

and then simply:

systemctl enable rhel-domainname

systemctl restart rhel-domainname

vim /etc/sysconfig/network

NISDOMAIN=rhce

source /etc/sysconfig/network

4.固定NIS端口

vim /etc/sysconfig/network

YPSERV_ARGS="-p 834"

source /etc/sysconfig/network

5.启动服务

systemctl enable ypserv.service

systemctl start ypserv.service

6.初始化nis数据库

/usr/lib64/yp/ypinit -m

7.防火墙设置

firewall-cmd --add-service=rpc-bind --permanent

firewall-cmd --add-port=834/tcp --permanent

firewall-cmd --add-port=834/udp --permanent

firewall-cmd --reload

 

02 NIS-client

1.安装软件

yum install ypbind -y

2.加入NIS域

authconfig-tui

3.启动服务

systemctl enable ypbind

systemctl restart ypbind

4.初步验证

getent passwd nis-user1

getent passwd nis-user2

5.进一步验证用户登录

su - nis-user1

su - nis-user2

6.进一步验证域名解析

vim /etc/nsswitch.conf

line39:

hosts: nis files dns

ping storage-1.example.com 可以正常ping通

vim /etc/nsswitch.conf

line39:

hosts: files dns

ping storage-1.example.com 无法ping通

03 NFS-server-share home directory

1.共享server0端用户家目录

vim /etc/exports

/home *(rw,sync)

2.启动服务

systemctl enable nfs-server.service

systemctl restart nfs-server.service

3.设置防火墙

firewall-cmd --add-service=nfs-server --permanent

firewall-cmd --add-service=mountd --permanent

firewall-cmd --reload

04 NFS-client

1.查看server0端的NFS共享

showmount -e 172.25.0.11

2.挂载server0端NFS共享

vim /etc/fstab

172.25.0.11:/home /home nfs defaults 0 0

mount -a

3.NIS+NFS验证

su - nis-user1

su - nis-user2

05 Autofs-server

1.安装软件

yum install autofs -y

2.配置autofs

主配置文件

touch /etc/auto.master.d/home.autofs

vim /etc/auto.master.d/home.autofs

/home /etc/auto.home

辅配置文件

touch /etc/auto.home

vim /etc/auto.home

* -rw,sync 172.25.0.11:/home/&

3.重启服务

systemctl enable autofs.service

systemctl restart autofs.service

4.验证autofs自动挂载

su - nis-user1

su - nis-user2

mount
