要求

一、在主机上提供web，dns服务

服务端

IP：172.25.250.131/24

dns：172.25.250.131

[root@localhost ~]# cd /etc/httpd/conf.d[root@localhost conf.d]# vim vhost.conf

[root@localhost conf.d]# mkdir /nfs/rhce -p[root@localhost conf.d]# echo welcome to www.rhce.com > /nfs/rhce/index.html[root@localhost conf.d]# vim /etc/named.conf

[root@localhost conf.d]# vim /var/named/named.rhce

[root@localhost conf.d]# vim /etc/hosts

[root@localhost conf.d]# firewall-cmd --permanent --add-service=httpsuccess[root@localhost conf.d]# firewall-cmd --permanent --add-service=dnssuccess[root@localhost conf.d]# firewall-cmd --reloadsuccess[root@localhost conf.d]# systemctl restart httpd[root@localhost conf.d]# systemctl restart named

 1.2主机域名解析

[root@localhost conf.d]# dig -t A www.rhce.com

1.3查看

[root@localhost conf.d]# curl www.rhce.com
welcome to www.rhce.com

2.nfs共享以及autofs自动挂载

2.1编辑nfs配置文件，新建共享目录，并设置权限

服务端（172.25.250.131/24）

[root@localhost ~]# mkdir /nfs/rhce -p[root@localhost ~]# chmod -Rf 777 /nfs/rhce[root@localhost ~]# vim /etc/exports[root@localhost ~]#  cat /etc/exports
/nfs/rhce 172.25.250.132(rw,sync,all_squash)[root@localhost ~]# systemctl restart rpcbind
[root@localhost ~]# systemctl restart nfs-server.service [root@localhost ~]# systemctl enable rpcbind
[root@localhost ~]# systemctl enable nfs-server.service 

 2.2配置放行防火墙规则

firewall-cmd --permanent --add-service=nfsfirewall-cmd --permanent --add-service=mountdfirewall-cmd --permanent --add-service=rpc-bindfirewall-cmd --reload

[root@localhost ~]# vim /etc/exports

客户端（172.25.250.132/24）

[root@localhost nfs2]# vim /etc/auto.nfs //书写本地挂载目录的子目录及远程共享目录

[root@localhost nfs2]# vim /etc/auto.master

[root@localhost nfs2]# showmount -e 172.25.250.131

[root@localhost nfs2]# systemctl restart autofs

[root@localhost nfs2]# systemctl enable autofs

2.3测试

[root@localhost ~]# df -h //查看挂载信息，这里看还没有挂载

[root@localhost ~]# cd /nfs1 //进入本地挂载目录，会自动新建

[root@localhost ~]# cd /nfs2 //进入本地挂载的下级目录，会触发自动挂载

[root@localhost ~]# df -h //现在查看挂载信息，可以看到已经挂载上了
