Elasticsearch-1.7.0安装部署
1、首先去elasticsearch官网下载软件包版本1.7.0版本.
#wget https://download.elastic.co/elasticsearch/elasticsearch/elasticsearch-1.7.0.tar.gz
2、解压elasticsearch-1.7.0.tar.gz 软件包.
#tar zxf elasticsearch-1.7.0.tar.gz
3、es配置文件参数解释(真正配置不全用的到):
#集群名称标识了你的集群,自动探查会用到它。
#如果你在同一个网络中运行多个集群,那就要确保你的集群名称是独一无二的.
cluster.name: test-elasticsearch
#节点名称会在启动的时候自动生成,所以你可以不用手动配置。你也可以给节点指定一个特定的名称.
node.name: "elsearch1"
#允许这个节点被选举为一个主节点(默认为允许)
#node.master: true
#允许这个节点存储数据(默认为允许)
# node.data: true
#You can exploit these settings to design advanced cluster topologies.
# 你可以利用这些设置设计高级的集群拓扑
#
# 1. You want this node to never become a master node, only to hold data.
# This will be the "workhorse" of your cluster.
# 1. 你不想让这个节点成为一个主节点,只想用来存储数据。
# 这个节点会成为你的集群的“负载器”
#
# node.master: false # node.data: true
#You want this node to only serve as a master: to not store any data and
# to have free resources. This will be the "coordinator" of your cluster.
# 2. 你想让这个节点成为一个主节点,并且不用来存储任何数据,并且拥有空闲资源。
# 这个节点会成为你集群中的“协调器”
# node.master: true # node.data: false
# Use the Cluster Health API [http://localhost:9200/_cluster/health], the
# Node Info API [http://localhost:9200/_nodes] or GUI tools
#使用集群体检API[http://localhost:9200/_cluster/health] ,
# 节点信息API[http://localhost:9200/_cluster/nodes] 或者GUI工具例如:
# A node can have generic attributes associated with it, which can later be used
# for customized shard allocation filtering, or allocation awareness. An attribute
# is a simple key value pair, similar to node.key: value, here is an example:
# 一个节点可以附带一些普通的属性,这些属性可以在后面的自定义分片分配过滤或者allocation awareness中使用。
# 一个属性就是一个简单的键值对,类似于node.key: value, 这里有一个例子:
# node.rack: rack314
# By default, multiple nodes are allowed to start from the same installation location
# to disable it, set the following:
# 默认的,多个节点允许从同一个安装位置启动。若想禁止这个特性,按照下面所示配置:
# node.max_local_storage_nodes: 1
# Set the number of shards (splits) of an index (5 by default):
# 设置一个索引的分片数量(默认为5)
# index.number_of_shards: 5
# Set the number of replicas (additional copies) of an index (1 by default):
# 设置一个索引的副本数量(默认为1)
# index.number_of_replicas: 1
# Note, that for development on a local machine, with small indices, it usually
# makes sense to "disable" the distributed features:
# 注意,为了使用小的索引在本地机器上开发,禁用分布式特性是合理的做法。
# index.number_of_shards: 1 # index.number_of_replicas: 0
# Path to directory containing configuration (this file and logging.yml):
# 包含配置(这个文件和logging.yml)的目录的路径
# path.conf: /path/to/conf
# Path to directory where to store index data allocated for this node.
# 存储这个节点的索引数据的目录的路径
# path.data: /path/to/data
# Can optionally include more than one location, causing data to be striped across
# the locations (a la RAID 0) on a file level, favouring locations with most free
# space on creation. For example:
# 可以随意的包含不止一个位置,这样数据会在文件层跨越多个位置(a la RAID 0),创建时会
# 优先选择大的剩余空间的位置
# path.data: /path/to/data1,/path/to/data2
# Path to temporary files:
# 临时文件的路径
# path.work: /path/to/work
# Path to log files:
# 日志文件的路径
# path.logs: /path/to/logs
# Path to where plugins are installed:
# 插件安装路径
# path.plugins: /path/to/plugins
# If a plugin listed here is not installed for current node, the node will not start.
# 如果当前结点没有安装下面列出的插件,结点不会启动
# plugin.mandatory: mapper-attachments,lang-groovy
# ElasticSearch performs poorly when JVM starts swapping: you should ensure that
# it _never_ swaps.
# 当JVM开始swapping(换页)时ElasticSearch性能会低下,你应该保证它不会换页
# Set this property to true to lock the memory:
# 设置这个属性为true来锁定内存
# bootstrap.mlockall: true
# Make sure that the ES_MIN_MEM and ES_MAX_MEM environment variables are set
# to the same value, and that the machine has enough memory to allocate
# for ElasticSearch, leaving enough memory for the operating system itself.
# 确保ES_MIN_MEM和ES_MAX_MEM环境变量设置成了同一个值,确保机器有足够的内存来分配
# 给ElasticSearch,并且保留足够的内存给操作系统
# You should also make sure that the ElasticSearch process is allowed to lock
# the memory, eg. by using `ulimit -l unlimited`.
# 你应该确保ElasticSearch的进程可以锁定内存,例如:使用`ulimit -l unlimited`
# ElasticSearch, by default, binds itself to the 0.0.0.0 address, and listens
# on port [9200-9300] for HTTP traffic and on port [9300-9400] for node-to-node
# communication. (the range means that if the port is busy, it will automatically
# try the next port).
# 默认的ElasticSearch把自己和0.0.0.0地址绑定,HTTP传输的监听端口在[9200-9300],节点之间
# 通信的端口在[9300-9400]。(范围的意思是说如果一个端口已经被占用,它将会自动尝试下一个端口)
# Set the bind address specifically (IPv4 or IPv6):
# 设置一个特定的绑定地址(IPv4 or IPv6):
# network.bind_host: 192.168.0.1
# Set the address other nodes will use to communicate with this node. If not
# set, it is automatically derived. It must point to an actual IP address.
# 设置其他节点用来与这个节点通信的地址。如果没有设定,会自动获取。
# 必须是一个真实的IP地址。
# network.publish_host: 192.168.0.1
# Set both ‘bind_host‘ and ‘publish_host‘:
# ‘bind_host‘和‘publish_host‘都设置
# network.host: 192.168.0.1
# Set a custom port for the node to node communication (9300 by default):
# 为节点之间的通信设置一个自定义端口(默认为9300)
# transport.tcp.port: 9300
# Enable compression for all communication between nodes (disabled by default):
# 为所有的节点间的通信启用压缩(默认为禁用)
# transport.tcp.compress: true
# Set a custom port to listen for HTTP traffic:
# 设置一个监听HTTP传输的自定义端口
# http.port: 9200
# Set a custom allowed content length:
# 设置一个自定义的允许的内容长度
# http.max_content_length: 100mb
# Disable HTTP completely:
# 完全禁用HTTP
# http.enabled: false
3、操作系统配置
1.文件描述符
vim /etc/security/limits.conf添加 * soft nofile 655350 * hard nofile 655350
退出当前用户重新login就会生效,使用ulimit -n验证下。
2.最大内存映射区数量,禁用swap交换分区
vim /etc/sysctl.conf增加 vm.max_map_count=262144 vm.swappiness=1 修改完成后sysctl -p
jvm参数配置
ES_HOME的bin目录下有一个elasticsearch.in.sh文件,修改
ES_MIN_MEM=256m ES_MAX_MEM=1g
为合适的值
4、es的插件安装:
Marvel是Elasticsearch的管理和监控工具,对于开发使用免费的。它配备了一个叫做Sense的交互式控制台,方便通过浏览器直接与Elasticsearch交互。
Marvel是一个插件,在Elasticsearch目录中运行以下代码来下载和安装:
./plugin -i elasticsearch/marvel/latest
elasticsearch-head是一个elasticsearch的集群管理工具,它是完全由html5编写的独立网页程序,你可以通过插件把它集成到es。
#./plugin -install mobz/elasticsearch-head
地址:http://172.16.2.24:25556/_plugin/head/
elasticsearch插件bigdesk安装:
bigdesk是elasticsearch的一个集群监控工具,可以通过它来查看es集群的各种状态,如:cpu、内存使用情况,索引数据、搜索情况,http连接数等。
在cmd命令行中进入安装目录,再进入 bin目录,运行以下命令:
#./plugin -install lukas-vlcek/bigdesk
在浏览器中输入:http://172.16.2.24:25556/_plugin/bigdesk可以看到效果
注意:elasticsearch 分词ik的安装,如果不安装分词ik插件,根本建不了索引,并且让访问http://172.16.2.24:25556/_plugin/head/ 集群一片空白,点击web 创建索引页没有反应。
注意:github https://github.com/medcl/elasticsearch-analysis-ik 给出了对应的es的ik版本,1.7.0的es对应的1.2.6的版本,开始我这块装了1.8的ik,创建索引失败,后台也是报ik的错误。
ik:1.2.6版本的下载:https://github.com/medcl/elasticsearch-analysis-ik/releases?after=v1.6.1
安装操作:
下载zip包解压到一个目录解压缩:
#unzip elasticsearch-analysis-ik-master.zip
安装mavne环境,apache 官网下载软件包设置环境变量:
#export PATH=$PATH:/usr/local/maven/bin
因为是源代码,此处需要使用maven打包,进入解压文件夹中,执行命令:
#cd elasticsearch-analysis-ik-master #mvn clean package
#在es的plugin目录下创建ik目录,并将target目录下的elasticsearch-analysis-ik-1.2.6.jar copy 到ik目录下。
[root@localhost target]# cd /data/elasticsearch-1.7.0 [root@localhost elasticsearch-1.7.0]# ls bin config data lib LICENSE.txt logs NOTICE.txt plugins README.textile [root@localhost elasticsearch-1.7.0]# cd plugins/ [root@localhost plugins]# ls bigdesk head ik marvel [root@localhost plugins]# cd ik/ [root@localhost ik]# ls elasticsearch-analysis-ik-1.2.6.jar
注意:如果是集群,可以将jar分别copy至其他几台机器。
es配置文件需要添加入下行:
index: analysis: analyzer: ik: alias: [ik_analyzer] type: org.elasticsearch.index.analysis.IkAnalyzerProvider ik_max_word: type: ik use_smart: false ik_smart: type: ik use_smart: true marvel.agent.enabled: false
完整的es配置文件如下,三台同样的配置,除了hostip和node.name外.
# cat elasticsearch.yml cluster.name: test-es-cluster network.host: 172.16.2.24 node.name: "node24" discovery.zen.ping.unicast.hosts: ["172.16.2.24:25555","172.16.2.21:25555","172.16.2.23:25555"] index.number_of_shards: 5 discovery.zen.minimum_master_nodes: 2 script.groovy.sandbox.enabled: false transport.tcp.port: 25555 http.port: 25556 script.inline: off script.indexed: off script.file: off index: analysis: analyzer: ik: alias: [ik_analyzer] type: org.elasticsearch.index.analysis.IkAnalyzerProvider ik_max_word: type: ik use_smart: false ik_smart: type: ik use_smart: true marvel.agent.enabled: false
后台启动es服务:
[root@localhost bin]# pwd /data/elasticsearch-1.7.0/bin [root@localhost bin]# ./elasticsearch -d
三台集群的机器中找其中一台创建索引:
创建索引:
curl -X PUT ‘http://172.16.2.24:25556/index‘ {"acknowledged":true}
注意:返回结果为acknowledged":true 为成功.
通过浏览器访问:http://172.16.2.24:25556/_plugin/head/ 测试效果.
