nfs网络文件系统 iscsi网络存储部署
nfs
NFS(Network Files System)即网络文件系统,NFS文件系统协议允许网络中的主机通过TCP/IP协议进行资源共享,NFS客户端可以
像使用本地资源一样读写远端NFS服务端的资料,需要注意NFS服务依赖于RPC服务与外部通信,所以必需保证RPC服务能够正常
注册服务的端口信息才能正常使用NFS服务,但在红帽RHEL7系统中RPC服务已经默认运行(active)了,所以无需再配置RPC服务。
yum install nfs-utils -y
服务端
配置火墙策略
success
[[email protected] ~]# firewall-cmd --reload
success
[[email protected] ~]# firewall-cmd --permanent --add-service=mountd
success
[[email protected] ~]# firewall-cmd --reload
success
[[email protected] ~]# firewall-cmd --permanent --add-service=rpc-bind
success
[[email protected] ~]# firewall-cmd --reload
success
[[email protected] ~]# vim /etc/exports
/westos *(sync,rw)
格式: 共享目录的绝对路径 允许访问NFS资源的客户端(权限参数)
[[email protected] ~]# exportfs -rv ##检测刷新
exporting *:/westos
[[email protected] ~]# systemctl start nfs
yum install nfs-utils -y
测试:
[[email protected] ~]# showmount -e 172.25.254.110 ##显示nfs共享列表
Export list for 172.25.254.110:
/westos *
[[email protected] ~]# mount 172.25.254.144:/westos /mnt/
nfs系统可以在使用时自动挂载,在规定时间之后自动卸载
客户端:yum install autofs.x86_64 -y
systemctl start autofs.service
修改挂载时长:
[[email protected] ~]# vim /etc/sysconfig/autofs ##不同版本配置文件路径会有所不同,采用rpm -qc autofs 查看文件存放目录
13 TIMEOUT=10
[[email protected] ~]# systemctl restart autofs.service
10秒之后会发现被自动卸载
修改挂载目录
客户端:
mkdir /westos/llc/share
8 /nfs /etc/auto.nfs
9 /westos/llc /etc/auto.nfs ##/westos/llc为共享目录的上层目录
vim /etc/auto.nfs ##编辑挂载方式
1 westos -rw,vers=3 172.25.254.100:/westos
2 share -ro,vers=4 172.25.254.110:/westos ##挂载子目录 权限 挂载版本 挂载的绝对路径
测试:
mkdir /westos/llc/share -p
cd /westos/llc/share
df
172.25.254.144:/westos 10473984 3226880 7247104 31% /westos/llc/share
文件参数
vim /etc/exports
/westos 172.25.254.124(sync,rw,anonuid=1000,anongid=1000,no_root_squash) 172.25.254.0/24(rync,ro)
systemctl restart nfs
共享路径 允许该ip登陆 (文件同步,读写权限,允许该用户登陆,当NFS客户端使用root用户访问时,映射为NFS服务端的root用户)
exportfs -rv
