采集数据

./nmon_linux_x86_64 -s1 -c600 -f -m /home/ipms/test/

参数解释：

• -s10 每 10 秒采集一次数据。
• -c60 采集 60 次，即为采集十分钟的数据。
• -f 生成的数据文件名中包含文件创建的时间。
• -m 生成的数据文件的存放目录。

这样就会生成一个 nmon 文件，并每十秒更新一次，直到十分钟后。
生成的文件名如： _090824_1306.nmon

生成报表

下载 nmon analyser (生成性能报告的免费工具)：

将之前生成的 nmon 数据文件传到 Windows 机器上，用 Excel 打开分析工具 nmon analyser v33C.xls 。

点击 Excel 文件中的 “Analyze nmon data” 按钮，选择 nmon 数据文件，这样就会生成一个分析后的结果文件： hostname_090824_1306.nmon.xls ，用 Excel打开生成的文件就可以看到结果了。

如果宏不能运行，需要做以下操作：
工具 -> 宏 -> 安全性 -> 中，然后再打开文件并允许运行宏。

Downloading Mesos

wget http://mirror.dsrg.utoronto.ca/apache/mesos/1.3.0/mesos-1.3.0.tar.gz
tar -zxf mesos-1.3.0.tar.gz 

System Requirements

Make sure your hostname is resolvable via DNS or via /etc/hosts to allow full support of Docker’s host-networking capabilities, needed for some of the Mesos tests. When in doubt, please validate that /etc/hosts contains your hostname.

Installing KDCs

When setting up Kerberos in a production environment, it is best to have multiple slave KDCs alongside with a master KDC to ensure the continued availability of the Kerberized services.

Each KDC contains a copy of the Kerberos database. The master KDC contains the writable copy of the realm database, which it replicates to the slave KDCs at regular intervals. All database changes (such as password changes) are made on the master KDC. Slave KDCs provide Kerberos ticket-granting services, but not database administration, when the master KDC is unavailable.

Install and configure the master KDC

For the purpose of this document we will use the following names:

kerberos.mit.edu    - master KDC
kerberos-1.mit.edu  - slave KDC
ATHENA.MIT.EDU      - realm name
.k5.ATHENA.MIT.EDU  - stash file
admin/admin         - admin principal

See MIT Kerberos defaults for the default names and locations of the relevant to this

Overview

The NFS Gateway supports NFSv3 and allows HDFS to be mounted as part of the client’s local file system. Currently NFS Gateway supports and enables the following usage patterns:

• Users can browse the HDFS file system through their local file system on NFSv3 client compatible operating systems.
• Users can download files from the the HDFS file system on to their local file system.
• Users can upload files from their local file system directly to the HDFS file system.
• Users can stream data directly to HDFS through the mount point. File append is supported but random write is not supported.

The NFS gateway machine needs the same thing to run an HDFS client like Hadoop JAR files, HADOOP_CONF directory. The NFS gateway can be on the same host as DataNode, NameNode, or any HDFS client.

Configuration

in core-site.xml of the namenode, the following must be set( in non-secure mode)

<property>
  <name>hadoop.proxyuser.nfs
