SolrCloud分布式集群部署步骤

百般思念 提交于 2019-11-27 06:09:10
Solr及SolrCloud简介     Solr是一个独立的企业级搜索应用服务器,它对外提供类似于Web-service的API接口。用户可以通过http请求,向搜索引擎服务器提交一定格式的XML文件,生成索引;也可以通过Http Get操作提出查找请求,并得到XML格式的返回结果。     SolrCloud是Solr4.0版本以后基于Solr和Zookeeper的分布式搜索方案,它的主要思想是使用Zookeeper作为集群的配置信息中心。它有以下几个特点: 集中式的配置信息管理。 自动容错。 近实时搜索。 查询时自动负载均衡。 将索引存储在HDFS上。 通过MR批量创建索引。     更多关于SolrCloud的相关介绍可参考以下链接: http://www.chepoo.com/solrcloud-introduction.html http://www.cnblogs.com/phinecos/archive/2012/02/10/2345634.html https://cwiki.apache.org/confluence/display/solr/SolrCloud 软件包准备 jdk-7u79-linux-x64.tar.gz apache-tomcat-7.0.62.tar.gz solr-5.2.1.tgz zookeeper-3.4.6.tar.gz

Automate scp file transfer using a shell script

家住魔仙堡 提交于 2019-11-27 05:58:12
I have some n number of files in a directory on my unix system. Is there a way to write a shellscript that will transfer all those files via scp to a specified remote system. I'll specify the password within the script, so that I don't have to enter it for each file. Instead of hardcoding password in a shell script, use SSH keys, its easier and secure. $ scp -i ~/.ssh/id_rsa devops@myserver.org:/path/to/bin/*.derp . assuming your private key is at ~/.ssh/id_rsa To generate a public / private key pair : $ ssh-keygen -t rsa The above will generate 2 files, ~/.ssh/id_rsa (private key) and ~/.ssh

HDFS常见功能

文章目录 HDFS常见功能 集群间数据拷贝 文件归档 快照管理 回收站 HDFS常见功能 集群间数据拷贝 scp实现两个远程主机之间的文件复制 scp -r hello.txt root@bigdata111:/user/itstar/hello.txt // 推 push scp -r root@bigdata112:/user/itstar/hello.txt hello.txt // 拉 pull 需要注意的是,无论是拷过去还是拷过来,路径都需要包含文件名。 适用于如果在两个远程主机之间ssh没有配置的情况下可以使用该方式。 采用distcp命令实现两个hadoop集群之间的递归数据复制(注:不用设置其他,直接写IP) eg: bin/hadoop distcp hdfs://192.168.1.51:9000/LICENSE.txt hdfs://192.168.1.111:9000/HAHA 文件归档 每个文件均按块存储,每个块的元数据存储在namenode的内存中,因此hadoop存储小文件会非常低效。因为大量的小文件会耗尽namenode中的大部分内存。但注意,存储小文件所需要的磁盘容量和存储这些文件原始内容所需要的磁盘空间相比也不会增多。例如,一个1MB的文件以大小为128MB的块存储,使用的是1MB的磁盘空间,而不是128MB。 Hadoop存档文件或HAR文件

Git fetch/pull/clone hangs on receiving objects

白昼怎懂夜的黑 提交于 2019-11-27 03:49:15
When fetching or pulling from git repositories, or cloning a repository, I get to this point: remote: Counting objects: 6666, done. remote: Compressing objects: 100% (5941/5941), done. Receiving objects: 23% (1534/6460), 11.68 MiB | 23 KiB/s And it hangs. The 23%/number of objects isn't a given, it ranges from single digits to up to the 60s, it seems. Also the speed for download listed freezes -- it's not like it slowly crawls down towards zero. The guy I sit next to has no issues, so it's not a router problem. We use beanstalk for our work repositories, but I have the issue from beanstalk and

Explanation for SCP protocol implementation in JSch library

邮差的信 提交于 2019-11-27 03:45:11
问题 I am contemplating over an example of JSch library usage which can be found here: http://www.jcraft.com/jsch/examples/ScpFrom.java.html I cannot understand several code patterns from this example. Here they are: Is there any reasons to prefer SCP over SFTP, which can be ran using the same library? Why we run scp -f <remote file> on remote host instead of running simply scp source_file_path destination_file_path ? Why execution on remote host is better? In the beginning of the transfer there

Transferring files over SSH [closed]

I'm SSHing into a remote server on the command line, and trying to copy a directory onto my local machine with the scp command. However, the remote server returns this "usage" message: [Stewart:console/ebooks/discostat] jmm% scp -p ./styles/ usage: scp [-1246BCEpqrv] [-c cipher] [-F ssh_config] [-i identity_file] [-l limit] [-o ssh_option] [-P port] [-S program] [[user@]host1:]file1 [...] [[user@]host2:]file2 [Stewart:console/ebooks/discostat] jmm% I'd like to be able to transfer files in both directions. From what I read, I thought the above command would work for downloading, and scp -p

使用scp在windows和Linux之间互传文件

a 夏天 提交于 2019-11-27 01:51:57
转自伍哥的文章 在做系统架构实验的时候,少不了碰到要在本地机和Linux服务器之间传东西,比如数据库文件等。 平时在Linux之间传个东西还是挺方便的,用过scp就okay了。如果能够在windows和linux之间也能这么方便的话就好了。 基于这样的想法,伍哥google了一把,发现了一个好东西:WinSSHD,就是让windows也支持ssh协议。 1,安装 WinSSHD 首先下载WinSSHD:http://123yun.newhua.com/down/WinSSHD5-Inst.zip 然后双击安装,安装的时候选择personal,就是个人使用,避免了30天后过期。 最后通过winsshd的面板启动ssh服务,如图: 2,测试scp在windows和Linux之间互传文件 先登录到你的Linux服务器,比如伍哥的是192.168.1.20。还有确认一下windows机器的IP,伍哥这边是192.168.1.30。 1 2 3 4 # windows -> linux scp administrator@192.168.1.30: /d : /mysql .sql ./ # linux -> windows scp . /install .log administrator@192.168.1.30: /d :/ 文件传输的时候,WinSSHD会产生悬浮提示。 来源:

scp (secure copy) to ec2 instance without password

谁都会走 提交于 2019-11-26 23:44:48
问题 I have an EC2 instance running (FreeBSD 9 AMI ami-8cce3fe5), and I can ssh into it using my amazon-created key file without password prompt, no problem. However, when I want to copy a file to the instance using scp I am asked to enter a password: scp somefile.txt -i mykey.pem root@my.ec2.id.amazonaws.com:/ Password: Any ideas why this is happening/how it can be prevented? 回答1: I figured it out. I had the arguments in the wrong order. This works: scp -i mykey.pem somefile.txt root@my.ec2.id
