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
