1、关闭防火墙(4步) root@cq ~]# systemctl stop firewalld [root@cq ~]# systemctl disable firewalld [root@cq ~]# vim /etc/selinux/config [root@cq ~]# setenforce 0 2、安装nfs服务(nfs-utils rpcbind) [root@cq ~]# yum -y install nfs-utils [root@cq ~]# yum -y install rpcbind 已加载插件:product-id, search-disabled-repos, subscription-manager This system is 3、启动nfs服务 和 rpcbind [root@cq ~]# systemctl start nfs-server [root@cq ~]# systemctl start rpcbind 4、编辑配置文件的共享目录 5、重启nfs服务 [root@cq ~]# systemctl restart nfs-server rpcbind 6、创建共享目录 [root@cq ~]# mkdir /chenqian 客户端: 1、关闭防火墙(4步 [root@chenqian ~]# systemctl stop firewalld [root@chenqian ~]# systemctl disable firewalld Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service. [root@chenqian ~]# systemctl disable firewalld [root@chenqian ~]# vim /etc/selinux/ config final/ semanage.conf targeted/ tmp/ [root@chenqian ~]# vim /etc/selinux/ config final/ semanage.conf targeted/ tmp/ [root@chenqian ~]# vim /etc/selinux/ config final/ semanage.conf targeted/ tmp/ [root@chenqian ~]# vim /etc/selinux/config 2、搭建nfs服务 [root@chenqian ~]# yum -y install nfs-utils rpcbind 已加载插件:product-id, search-disabled-repos, subscription-manager 3、启动nfs服务 [root@chenqian ~]# systemctl start nfs-server rpcbind 4、验证nfs服务端的共享目录 [root@chenqian ~]# showmount -e 172.16.195.128 Export list for 172.16.195.128: /chenqian 172.16.195.129 5、创建挂载的目录站点 [root@chenqian ~]# mkdir /nfs 6、挂载 [root@chenqian ~]# mount -t nfs 172.16.195.128:/chenqian /nfs 7、然后在服务端为共享目录设置匿名用户和组 [root@cq ~]# chown -R nfsnobody.nfsnobody /chenqian 8、在客户端验证挂载目录站点是否可以创建文件和删除文件 [root@chenqian nfs]# touch 4 5 touch: 无法创建"4": 只读文件系统 touch: 无法创建"5": 只读文件系统 [root@chenqian nfs]# touch 4 5 [root@chenqian nfs]# ls 1 2 3 4 5

作业 1.手动搭建一个nfs服务器

开放/nfs/shared目录,供所有用户查阅资料 开放/nfs/upload目录为172.16.12.0/24网段的数据上传目录,并将所有用户及所属的用户组都映射为nfs-upload,其UID与GID均为300

[root@cq ~]# mkdir -p /nfs/{shared,upload} [root@cq nfs]# ls shared upload [root@cq nfs]# vim /etc/exports /chenqian 172.16.195.129(rw) /nfs/shared *(ro) /nfs/upload 172.16.195.0/24(rw,anonuid=300,anongid=300)

[root@cq nfs]# exportfs -r chown -R 300.300 /nfs/upload/

[root@chenqian ~]# vim /etc/fstab 172.16.195.128:/nfs /cq nfs defaults,_netdev 0 0 [root@chenqian ~]# mount -a [root@chenqian upload]# touch 2 3 [root@chenqian upload]# ll 总用量 0 -rw-r--r--. 1 300 300 0 7月 2 18:19 2 -rw-r--r--. 1 300 300 0 7月 2 18:19 3
