AIX 上使用NFS实现AIX之间文件网络共享

tomroom.cublog.cn 作者：tomroom 环保男 环境AIX 6.1

AIX 可以使用NFS在AIX之间实现类似window共享文件夹功能，在多台aix上安装系统补丁的时候比较有用只需要在一台服务器上FTP上传，其他AIX通过共享访问（注意不要多台一起访问可能会由于I/O繁忙带有问题）

注意：

1. 多台AIX之前在同一个局域网子网段中没有问题，若跨网段请确认网络开通NFS端口

2. 下面我都是用root账户登录操作

3. 要在A,B两端的/etc/hosts里互相都加上彼此的IP地址和hostname（若不用DNS都通过hosts表里name

l 第一部分在AIX服务器A 上面建里要通过NFS共享的目录比如：根目录下/test目录

# ls -l total 8 -rw-r----- 1 root system 543 Jul 24 03:39 temp.txt

/test目录中存放一个文件temp.txt内容如下，后面可以用这个验证共享成功

# cat temp.txt SBMJOB CMD(STROBJCVN LIB(*ALLUSR)) LOG(4 0 *SECLVL) S6564E5B 定时任务 DAILY4 HOLD 磁带机中磁带 卷标 001176推入磁带机TAP07 Opt Queue Manager Port HHT 1417 MQM HHT Opt Queue Manager Port HHT 1414 HHT 1417

A机器上运行# smit nfs

先选择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

再选择Add a Directory to Exports List（先Change / Show Attributes of an Exported Directory确认目录之前没有被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

下面画面中* Pathname of directory to export 输入导出目录路径和名称 [/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 []

运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 第二部分在另外一台服务器B上

运行smitty nfs选择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机器上选择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机上mount点

Pathname of remote directory填A机上路径

Host where remote directory resides填A机主机名（在A机器上运行hostname获得）

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两端的/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机器上/etc/hosts文件增加A服务器的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.

若有如下错误可能网络上没有开放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机上smit mount中 List all能看到mount上文件验证，并访问共享文件内容确认可以访问

l 卸载

取消在B机上可以用smit umount指定上面B机上mount点可以在B机器上取消该NFS

在A机器上卸载，smit nfs选择Remove a Directory from Exports List 输入路径

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 权限

我两台机器都是用root账户访问权限两台都是如下一样

# ls -l total 8 -rw-r----- 1 root system 543 Jul 24 06:10 temp.txt

l 附录：

l windows端也能访问AIX NFS ，也有建议window访问aix文件系统SAMBA比NFS好

比如：http://www.chinaunix.net/jh/9/503373.html

经常碰到一些客户需要将PC Server的数据定期放到运行AIX操作系统的6000小机的 磁带机上备份，做了几个这样的案例 Share一下：）
1、下载SFU
SFU是微软的一款与UNIX系统进行文件共享的软件 100M左右。可在Windows端模拟NFS Server 或者使 Windows成为NFS Client。他是免费的。下载时需要.net帐户（msn的就行）
2、在Windows端安装SFU软件。选择作为NFS Client。安装时间较长。安装结束后可以在网上邻居中发现新增加了一个叫做SFU的 工作组（好像是这个名字）
在上面点击右键选择添加，将6000的IP地址加入。在6000一端开启NFS服务。刷新后就可看到该服务器了
3、身分认证：在两端建立相同帐号，需要在6000上编辑/etc/hosts文件。将需要访问NFS路径的服务器IP地址与机器名称加入。这是 在PC Server端就可以访问该共享文件夹了。在上面还可进行权限的管理 有兴趣的自己实验吧。

最后：使用Windows备份策略定期将被分文件写入该文件夹。在AIX上编辑crontab即可。
