AIX 上使用NFS實(shí)現(xiàn)AIX之間文件網(wǎng)絡(luò)共享
AIX 可以使用NFS在AIX之間實(shí)現(xiàn)類似window共享文件夾功能，在多臺(tái)aix上安裝系統(tǒng)補(bǔ)丁的時(shí)候比較有用只需要在一臺(tái)服務(wù)器上FTP上傳，其他AIX通過共享訪問（注意不要多臺(tái)一起訪問可能會(huì)由于I/O繁忙帶有問題）
注意：
1. 多臺(tái)AIX之前在同一個(gè)局域網(wǎng)子網(wǎng)段中沒有問題，若跨網(wǎng)段請(qǐng)確認(rèn)網(wǎng)絡(luò)開通NFS端口
2. 下面我都是用root賬戶登錄操作
3. 要在A,B兩端的/etc/hosts里互相都加上彼此的IP地址和hostname（若不用DNS都通過hosts表里name
l 第一部分在AIX服務(wù)器A 上面建里要通過NFS共享的目錄比如：根目錄下/test目錄
# ls -l total 8 -rw-r----- 1 root system 543 Jul 24 03:39 temp.txt |
/test目錄中存放一個(gè)文件temp.txt內(nèi)容如下，后面可以用這個(gè)驗(yàn)證共享成功
# cat temp.txt SBMJOB CMD(STROBJCVN LIB(*ALLUSR)) LOG(4 0 *SECLVL)

A機(jī)器上運(yùn)行# smit nfs
先選擇Network File System (NFS)
NFS
Move cursor to desired item and press Enter.
Configure TCP/IP (If Not Already Configured) Network File System (NFS) Network Information Service (NIS) Configure Secure NFS & NIS
|
再選擇Add a Directory to Exports List（先Change / Show Attributes of an Exported Directory確認(rèn)目錄之前沒有被Exported
Network File System (NFS)
Move cursor to desired item and press Enter.
Configure NFS on This System Add a Directory to Exports List Change / Show Attributes of an Exported Directory Remove a Directory from Exports List Add a File System for Mounting Change / Show Attributes of an NFS File System Remove an NFS File System Flush NFS V4 Translation Cache Add NFSv4 File System FSID Options Change / Show NFSv4 File System FSID Options Reset NFSv4 File System FSID Options |
下面畫面中* Pathname of directory to export 輸入導(dǎo)出目錄路徑和名稱 [/test]
Add a Directory to Exports List
Type or select values in entry fields. Press Enter AFTER making all desired changes.
[TOP] [Entry Fields] * Pathname of directory to export [/test] Anonymous UID [-2] Public filesystem? no * Export directory now, system restart or both both []
|
運(yùn)行完成之后如下提示
COMMAND STATUS
Command: running stdout: yes stderr: no
Before command completion, additional instructions may appear below.
0513-059 The nfsd Subsystem has been started. Subsystem PID is 5505044. 0513-059 The rpc.mountd Subsystem has been started. Subsystem PID is 7077952. |
l 第二部分在另外一臺(tái)服務(wù)器B上
運(yùn)行smitty nfs選擇Network File System (NFS)
NFS
Move cursor to desired item and press Enter.
Configure TCP/IP (If Not Already Configured) Network File System (NFS) Network Information Service (NIS) Configure Secure NFS & NIS |
B機(jī)器上選擇Add a File System for Mounting
Network File System (NFS)
Move cursor to desired item and press Enter.
Configure NFS on This System Add a Directory to Exports List Change / Show Attributes of an Exported Directory Remove a Directory from Exports List Add a File System for Mounting Change / Show Attributes of an NFS File System Remove an NFS File System Flush NFS V4 Translation Cache Add NFSv4 File System FSID Options Change / Show NFSv4 File System FSID Options Reset NFSv4 File System FSID Options |
Pathname of mount point 填B機(jī)上mount點(diǎn)
Pathname of remote directory填A(yù)機(jī)上路徑
Host where remote directory resides填A(yù)機(jī)主機(jī)名（在A機(jī)器上運(yùn)行hostname獲得）
Add a File System for Mounting
Type or select values in entry fields. Press Enter AFTER making all desired changes.
[TOP] [Entry Fields] * Pathname of mount point [/tmp/test/] * Pathname of remote directory [/test] * Host where remote directory resides [svr05427] Mount type name [] * Security method [sys] * Mount now, add entry to /etc/filesystems or both? now * /etc/filesystems entry will mount the directory no on system restart.
|
注意： 要在A,B兩端的/etc/hosts里互相都加上彼此的IP地址和hostname
若提示not in hosts database 需要修改B機(jī)器上/etc/hosts文件增加A服務(wù)器的IP地址和hostname
COMMAND STATUS
Command: failed stdout: yes stderr: no
Before command completion, additional instructions may appear below.
mount: 1831-009 svr05427 not in hosts database mount: 1831- 008 giving up on: svr05427:/test A route to the remote host is not available.
|
若有如下錯(cuò)誤可能網(wǎng)絡(luò)上沒有開放NFS需要的端口
COMMAND STATUS
Command: failed stdout: yes stderr: no
Before command completion, additional instructions may appear below.
nfsmnthelp: 1831-019 svr05427: System call error number -1.
mount: 1831- 008 giving up on: svr05427:/test System call error number -1. |
成功之后可以在B機(jī)上smit mount中 List all能看到mount上文件驗(yàn)證，并訪問共享文件內(nèi)容確認(rèn)可以訪問
l 卸載
取消在B機(jī)上可以用smit umount指定上面B機(jī)上mount點(diǎn)可以在B機(jī)器上取消該NFS
在A機(jī)器上卸載，smit nfs選擇Remove a Directory from Exports List 輸入路徑
Network File System (NFS)
Move cursor to desired item and press Enter.
Configure NFS on This System Add a Directory to Exports List Change / Show Attributes of an Exported Directory Remove a Directory from Exports List Add a File System for Mounting Change / Show Attributes of an NFS File System Remove an NFS File System Flush NFS V4 Translation Cache Add NFSv4 File System FSID Options Change / Show NFSv4 File System FSID Options Reset NFSv4 File System FSID Options |
l 權(quán)限
我兩臺(tái)機(jī)器都是用root賬戶訪問權(quán)限兩臺(tái)都是如下一樣
# ls -l total 8 -rw-r----- 1 root system 543 Jul 24 06:10 temp.txt |
l 附錄：
l windows端也能訪問AIX NFS ，也有建議window訪問aix文件系統(tǒng)SAMBA比NFS好
比如：http://www.chinaunix.net/jh/9/503373.html
經(jīng)常碰到一些客戶需要將PC Server的數(shù)據(jù)定期放到運(yùn)行AIX操作系統(tǒng)的6000小機(jī)的 磁帶機(jī)上備份，做了幾個(gè)這樣的案例 Share一下：）
1、下載SFU
SFU是微軟的一款與UNIX系統(tǒng)進(jìn)行文件共享的軟件 100M左右?？稍赪indows端模擬NFS Server 或者使 Windows成為NFS Client。他是免費(fèi)的。下載時(shí)需要.net帳戶（msn的就行）
2、在Windows端安裝SFU軟件。選擇作為NFS Client。安裝時(shí)間較長(zhǎng)。安裝結(jié)束后可以在網(wǎng)上鄰居中發(fā)現(xiàn)新增加了一個(gè)叫做SFU的 工作組（好像是這個(gè)名字）
在上面點(diǎn)擊右鍵選擇添加，將6000的IP地址加入。在6000一端開啟NFS服務(wù)。刷新后就可看到該服務(wù)器了
3、身分認(rèn)證：在兩端建立相同帳號(hào)，需要在6000上編輯/etc/hosts文件。將需要訪問NFS路徑的服務(wù)器IP地址與機(jī)器名稱加入。這是 在PC Server端就可以訪問該共享文件夾了。在上面還可進(jìn)行權(quán)限的管理 有興趣的自己實(shí)驗(yàn)吧。
