| 22、创建客户端的/mfs目录： |
|
| 23、修改客户端文件系统配置文件，加入mfs的配置： |
| cd /opt/ltsp/i386/etc |
| vi fstab |
| |
| none /mfs mfs dfsa = 1 0 0 |
|
|
| 24、修改客户端启动进程脚本，加入启动openmosix的配置，禁止客户端提交集群计算的设置，和装载/mfs文件系统的配置。 |
| vi /opt/ltsp/i386/etc/rc.local |
| |
| # OpenMosix startup section |
| # we don't want any terminal processes
to migrate |
| echo 1 > /proc/mosix/admin/lstay |
| # start mosix |
| /etc/rc.openmosix start |
| # mount mfs filesystem. doesn't work when
done earlier |
| mount /mfs |
| # End OpenMosix Startup Section |
|
|
| 25、配置完成后准备软盘制作以太启网启动盘。访问www.Rom-O-matic.net网站，选择网卡类型生成以太网启 |
| 动芯片的映象，保存到Linux上，使用cat生成启动软盘。本例中使用3C905B。放入一张空白三吋软盘。 |
| cat eb-5[1].0.7-3c905b-tpo100.lzdsk
> /dev/fd0 |
|
|
| 26、修改LTSP客户端启动配置文件/opt/ltsp/i386/etc/lts.conf，禁止启动X Windows，修改参数X_USBMOUSE_BUTTONS
= 3， |
| 即启动文本界面。 |
| 27、确认/etc/exports文件包含共享客户端根文件系统和交换区内容： |
| more /etc/exports |
| |
| /opt/ltsp/i386 192.168.0.0/255.255.255.0(ro,no_root_squash) |
| /var/opt/ltsp/swapfiles 192.168.0.0/255.255.255.0(rw,no_root_squash) |
|
|
| 28、将以太启动软盘放入客户端，开机并确认正常启动，正常获得动态地址，加载内核成功，初始化脚本正常运行，主机名自动 |
| 生成，openmosix正常初始化，没有任何错误提示。 |
| 29、回到服务器，通过检查/mfs文件系统来检查mfs文件系统。 |
 |
| 30、启动mosmon监控程序来检查通讯是否有效，这是刚加入3个节点时，启动setiathome计算的状态。将下载的应用展开在/dw |
| 目录下，注意命令的格式。 |
| mosrun -j1-3 /mfs/1/dw/setiathome
-nolock |
|
|
 |
| 31、制作启动盘，陆续加入节点，MOSIX集群就创建完了。 |
