This section shows the configuration actions you perform on the management node before installing xCAT .

本节给出了在安装xCAT之前，在管理节点上应该执行的配置操作。

Set the TORQUE server name , then install the TORQUE startup script included in xCAT .

设置TORQUE服务器名，然后安装包含在xCAT内的TORQUE启动脚本。

The compute nodes are provisioned by the xCAT server running on the management node .

计算节点是由运行在管理节点上的xCAT服务器供应的。

XCAT will have support for Ganglia and PCP in a future release .

xCAT在未来的版本中将支持Ganglia和PCP。

As part of the installation process , the tables in the xCAT database are created and initialized .

作为安装过程的一部分，xCAT数据库表也会被创建和初始化。

XCAT stores the cluster configuration in a database ( the default database type is SQLite ) .

xCAT在一个数据库内存储了集群配置（默认的数据库类型是SQLite）。

The VCL used xCAT to load the requested bare-metal image to a blade server .

VCL使用xCAT将请求的裸机（bare-metal）映像加载到刀片服务器。

We will revisit the one I wrote on the xCAT wiki .

我们将重新查看我在xCAT维基中撰写的一篇文章。

But we 'll just end with this : Give xCAT a try if you are looking for ideas or something better .

但是，我们还是就此打住：如果您要寻找更好的工具或思想，请试试xCAT。

When n becomes free of jobs , instruct xCAT to provision n with OS ( n ) .

当n没有任何作业后，指示xCAT用OS（n）供应n。

When the installation is complete , the xCAT and the TFTP services should be configured and running .

在安装完成后，xCAT以及TFTP服务均应配置完毕并运行。

Before installing xCAT , configure the management node so xCAT is installed correctly and fetches the correct information about the cluster .

在安装xCAT之前，先配置管理节点，以便xCAT能被正确安装并能获得有关此集群的正确信息。

XCAT allows imaging , kickstart , autoyast , iscsi , and stateless for nearly every enterprise Linux distribution available .

xCAT可以针对几乎所有企业Linux发行版实现映像生成、kickstart、autoyast、iscsi和无状态。

The IPMI is used by xCAT to power-cycle and boot the compute the nodes .

IPMI被xCAT用来进行功率循环和引导计算节点。

We build a cluster where nodes are provisioned with xCAT and on which batch jobs are managed and executed by TORQUE .

我们所构建的这个集群，其中的节点由xCAT供应，并且其上的批量作业由TORQUE管理和执行。

The command uses the repository created with copycds to generate the root image for a node with one of the profiles that xCAT supports .

此命令使用了用copycds创建的存储库以便为一个具有受xCAT支持的概要文件的节点生成根映像。

Because xCAT expects the named service not to use chroot , remove the package bind-chroot , as shown in the listing .

由于xCAT期望此命名服务不使用chroot，所以需要删除包bind-chroot，如如下的清单所示。

Because xCAT is a database-driven package , you configure its actions by setting the tables in the xCAT database .

由于xCAT是一个数据库驱动的包，所以可以通过设置xCAT数据库内的表来配置其动作。

We 'll talk about these tools and graphs in a future article ; they will also publish as part of a future xCAT RPM that will greatly increase productivity .

我们将在以后的一篇文章中讨论基准测试工具和图表；在未来的xCATRPM中也会提供这些工具，这会极大地提高生产力。

Even though this article has described combining xCAT with the TORQUE workload and resource manager , you can combine xCAT with other open source or commercial workload and resource managers .

虽然本文探讨了xCAT与TORQUE工作负载和资源管理器的结合使用，但是您也可以结合xCAT与其他的开源或商业的工作负载和资源管理器。

Get the list C of compute nodes from xCAT , and for each node n in C , set the time T ( n ) when n is eligible for provisioning to the current time .

从xCAT获得计算节点的列表C，并且对于C内的每个节点n，若n具有供应给当前时间的资格，就设置时间T（n）。

The management node also runs the TORQUE server and scheduler daemons , as well as several services required to manage the compute nodes with xCAT , including DNS , DHCP , TFTP , and NFS .

管理节点还运行了TORQUE服务器和调度器守护程序，以及用xCAT管理计算节点所需的几个服务，包括DNS、DHCP、TFTP和NFS。
