CentOS 6 NFS的安裝配置

NFS的安裝配置：
centos 5 :
yum install nfs-utils portmap
centos 6 :
yum install nfs-utils rpcbind


本節是使用centos 6的配置過程：
裝置：兩臺 centos6 OS 安裝的時候選擇的是"Basic Server"軟體配置包。
首先，讓兩臺機器都安裝NFS的 軟體包，如下顯示的是伺服器端：
[root@roothomes /home]$ yum install nfs-utils rpcbind
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: centos.ustc.edu.cn
 * extras: centos.ustc.edu.cn
 * updates: centos.ustc.edu.cn

[root@roothomes /home]$

伺服器端：
###(建立掛載的目錄，並且掛載目錄。)
[root@roothomes /etc]$ mkdir /opt/centos6
[root@roothomes /etc]$ cd /opt/centos6/
[root@roothomes /opt/centos6]$ mkdir thisISnfsFile
[root@roothomes /opt/centos6]$ ls
thisISnfsFile
[root@roothomes /etc]$ vi /etc/exports
[root@roothomes /opt/centos6]$ cat /etc/exports

/opt/centos6 192.168.1.0/24(ro,no_root_squash)
### 備註:/opt/centos6表示nfs共享的目錄 192.168.1.0-192.168.1.254區間的IP可以訪問，訪問許可權是隻讀，root 使用者
###(啟動對應的服務)
[root@roothomes /opt/centos6]$ chkconfig nfs on
[root@roothomes /opt/centos6]$ /etc/init.d/rpcbind start
[root@roothomes /opt/centos6]$ /etc/init.d/nfs start
Starting NFS services:                                     [  OK  ]
Starting NFS quotas:                                       [  OK  ]
Starting NFS daemon:                                       [  OK  ]
Starting NFS mountd:                                       [  OK  ]
[root@roothomes /opt/centos6]$ service iptables stop

iptables: Unloading modules:                               [  OK  ]


客戶端：
[root@roothomes /home]$ yum install nfs-utils rpcbind
安裝完畢！
[root@vmBS00 ~]# service iptables stop
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Unloading modules:                               [  OK  ]
###檢視是否能訪問nfs服務
[root@vmBS00 ~]# showmount -e 192.168.1.75
Export list for 192.168.1.75:
/opt/centos6 192.168.1.0/24
[root@vmBS00 ~]# mkdir /opt/centos6
[root@vmBS00 ~]# mount -t nfs 192.168.1.75:/opt/centos6/  /opt/centos6/
[root@vmBS00 ~]# ls /opt/centos6/
thisISnfsFile
###配置開機自動掛載
[root@vmBS00 ~]# vi /etc/fstab
### 新增 #192.168.1.75:/opt/centos6/ /opt/centos6/ nfs nodev,ro,rsize=32768,wsize=32768 0 0
