制作U盘刷EXADATA
在XD需要刷机(方言重装操作系统),现在比较常见的是一种是使用PXE来刷机,另外一张是使用U盘制作启动盘来刷机.PXE配置起来比较麻烦,这里展示制作U盘刷机的过程.db节点和cell节点的制作方法基本相同,这里以cell节点的U盘制作为例说明制作过程
1. 前提条件
1) Linux 64位机器(最好直接在db和cell节点的机器上直接处理
2) U盘大小最少4G
3) 上传preconf.csv配置文件(使用java配置)
2. 下载image文件
通过888828.1文档找到image的名称,然后在edelivery中下载
3. 查看U盘盘符
[root@xifenfei tmp]# fdisk -l Disk /dev/sda: 32.2 GB, 32212254720 bytes 255 heads, 63 sectors/track, 3916 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 3655 29358756 83 Linux /dev/sda2 3656 3916 2096482+ 82 Linux swap / Solaris Disk /dev/sdb: 4048 MB, 4048551936 bytes 128 heads, 9 sectors/track, 6864 cylinders Units = cylinders of 1152 * 512 = 589824 bytes Device Boot Start End Blocks Id System /dev/sdb1 * 8 6864 3949096 b W95 FAT32
4. 上传压缩文件到服务器,并解压
unzip V36290-01.zip tar xvf cellImageMaker_11.2.3.2.1_LINUX.X64_130109-1.x86_64.tar
5. dl180内容

dcli完成多节点对等ssh配置
dcli是Python脚本,可以实现在多节点中的之间非交换命令的执行,因为dcli执行需要通过ssh来实现,所以dcli也提供了ssh配置功能.本文通过dcli来完成多节点间的对等ssh配置
dcli整体描述
The dcli utility runs commands on multiple cells in parallel threads. However, it does not support an interactive session with a remote application on a cell. To use the dcli utility, copy the utility from the bin directory on a cell to a host computer from which central management can be performed. You can issue a command to be run on multiple cells, or use files that can be copied to cells and then run. The cells are referenced by their domain name or IP address. The dcli utility requires Python version 2.3 or later. You can determine the version of Python by running the python -V command. In addition, use of this tool assumes prior setup of SSH user-equivalence to a cell. You can use the dcli utility initially with the -k option to set up SSH user-equivalence to a cell.
dcli使用说明

到此证明三个节点之间的xifenfei用户的ssh等效配置完成,实现使用dcli完成多节点ssh等效配置
整体处理思路总结
1.确定需要配置ssh用户 --第一节点 2.编辑需要配置ssh等效连接ip列表 3.ssh-keygen -t dsa 4.dcli -k -g xifenfei.txt -l xifenfei 5. for host in `cat xifenfei.txt` do scp /home/xifenfei/.ssh/id_dsa.pub ${host}:/home/xifenfei/.ssh/authorized_keys done 6.dcli -g xifenfei.txt -l xifenfei "chmod -R 700 /home/xifenfei/.ssh" 7.dcli -g xifenfei.txt -l xifenfei "chown -R xifenfei /home/xifenfei/.ssh" 8. for host in `cat xifenfei.txt` do scp /home/xifenfei/xifenfei.txt ${host}:/home/xifenfei/xifenfei.txt done --其他节点 9. ssh-keygen -t dsa 10. dcli -k -g xifenfei.txt -l xifenfei
cellcli命令简介
cellcli用途描述
The CellCLI utility is the command-line administration tool for Exadata Cell. CellCLI runs on each cell to enable you to manage an individual cell. You use CellCLI to start and stop the cell, to manage cell configuration information, to enable or disable cells, and to manage objects in the cell environment. The command-line utility is already installed when Exadata Cell is shipped.
cellcli语法
cellcli [port_number] [-n] [-m] [-xml] [-v | -vv | -vvv] [-x] [-e command]

attributes后面可以加上对应的属性,”.*”表示通配符
这里通过help和describe来实现cellcli的基本操作,这里只是提供了一种处理问题的思路,通过help操作来完成cellcli的基本操作.
