CentOS下 elasticsearch集羣安裝

1.進入root目錄並下載elasticsearch

cd /root
wget https://download.elastic.co/elasticsearch/elasticsearch/elasticsearch-1.7.3.tar.gz

2.解壓下載好的壓縮包

tar -zxvf elasticsearch-1.7.3.tar.gz

3.修改目錄名字爲node1（這裏須要安裝三個節點）

mv elasticsearch-1.7.3 elasticsearch-node3

4.修改/root/elasticsearch-node3/config/elasticsearch.yml 爲以下內容（注意紅色部分爲三個節點不一致的地方）

（下面配置未見爲node3的配置）

##################### Elasticsearch Configuration Example #####################

# This file contains an overview of various configuration settings,
# targeted at operations staff. Application developers should
# consult the guide at <http://elasticsearch.org/guide>.
#
# The installation procedure is covered at
# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/setup.html>.
#
# Elasticsearch comes with reasonable defaults for most settings,
# so you can try it out without bothering with configuration.
#
# Most of the time, these defaults are just fine for running a production
# cluster. If you're fine-tuning your cluster, or wondering about the
# effect of certain configuration option, please _do ask_ on the
# mailing list or IRC channel [http://elasticsearch.org/community].

# Any element in the configuration can be replaced with environment variables
# by placing them in ${...} notation. For example:
#
#node.rack: ${RACK_ENV_VAR}

# For information on supported formats and syntax for the config file, see
# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/setup-configuration.html>


################################### Cluster ###################################

# Cluster name identifies your cluster for auto-discovery. If you're running
# multiple clusters on the same network, make sure you're using unique names.
#
cluster.name: elasticsearch
#集羣名字， 相同集羣名字的節點啓動後會自動放一塊兒



#################################### Node #####################################

# Node names are generated dynamically on startup, so you're relieved
# from configuring them manually. You can tie this node to a specific name:
#
node.name: "es-node3"
#節點名字


# Every node can be configured to allow or deny being eligible as the master,
# and to allow or deny to store the data.
#
# Allow this node to be eligible as a master node (enabled by default):
#
#node.master: true
#
# Allow this node to store data (enabled by default):
#
#node.data: true

# You can exploit these settings to design advanced cluster topologies.
#
# 1. You want this node to never become a master node, only to hold data.
#    This will be the "workhorse" of your cluster.
#
#node.master: false
#node.data: true
#
# 2. 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.
#
#node.master: true
#node.data: false
#
# 3. You want this node to be neither master nor data node, but
#    to act as a "search load balancer" (fetching data from nodes,
#    aggregating results, etc.)
#
#node.master: false
#node.data: false

# Use the Cluster Health API [http://localhost:9200/_cluster/health], the
# Node Info API [http://localhost:9200/_nodes] or GUI tools
# such as <http://www.elasticsearch.org/overview/marvel/>,
# <http://github.com/karmi/elasticsearch-paramedic>,
# <http://github.com/lukas-vlcek/bigdesk> and
# <http://mobz.github.com/elasticsearch-head> to inspect the cluster state.

# 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:
#
#node.rack: rack314

# By default, multiple nodes are allowed to start from the same installation location
# to disable it, set the following:
#node.max_local_storage_nodes: 1


#################################### Index ####################################

# You can set a number of options (such as shard/replica options, mapping
# or analyzer definitions, translog settings, ...) for indices globally,
# in this file.
#
# Note, that it makes more sense to configure index settings specifically for
# a certain index, either when creating it or by using the index templates API.
#
# See <http://elasticsearch.org/guide/en/elasticsearch/reference/current/index-modules.html> and
# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/indices-create-index.html>
# for more information.

# Set the number of shards (splits) of an index (5 by default):
#
#index.number_of_shards: 5

# Set the number of replicas (additional copies) of an index (1 by default):
#
#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:
#
#index.number_of_shards: 1
#index.number_of_replicas: 0

# These settings directly affect the performance of index and search operations
# in your cluster. Assuming you have enough machines to hold shards and
# replicas, the rule of thumb is:
#
# 1. Having more *shards* enhances the _indexing_ performance and allows to
#    _distribute_ a big index across machines.
# 2. Having more *replicas* enhances the _search_ performance and improves the
#    cluster _availability_.
#
# The "number_of_shards" is a one-time setting for an index.
#
# The "number_of_replicas" can be increased or decreased anytime,
# by using the Index Update Settings API.
#
# Elasticsearch takes care about load balancing, relocating, gathering the
# results from nodes, etc. Experiment with different settings to fine-tune
# your setup.

# Use the Index Status API (<http://localhost:9200/A/_status>) to inspect
# the index status.


#################################### Paths ####################################

# Path to directory containing configuration (this file and logging.yml):
#
#path.conf: /path/to/conf

# Path to directory where to store index data allocated for this node.
#
#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:
#
#path.data: /path/to/data1,/path/to/data2

# Path to temporary files:
#
#path.work: /path/to/work

# Path to log files:
#
#path.logs: /path/to/logs

# Path to where plugins are installed:
#
#path.plugins: /path/to/plugins


#################################### Plugin ###################################

# If a plugin listed here is not installed for current node, the node will not start.
#
#plugin.mandatory: mapper-attachments,lang-groovy


################################### Memory ####################################

# Elasticsearch performs poorly when JVM starts swapping: you should ensure that
# it _never_ swaps.
#
# Set this property to true to lock the memory:
#
#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.
#
# You should also make sure that the Elasticsearch process is allowed to lock
# the memory, eg. by using `ulimit -l unlimited`.


############################## Network And HTTP ###############################

# 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).

# Set the bind address specifically (IPv4 or IPv6):
#
network.bind_host: 192.168.0.45
#綁定的ip（本機ip）


# 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.
#
network.publish_host: 192.168.0.45
#其餘節點和本節點的交互ip

# Set both 'bind_host' and 'publish_host':
#
network.host: 192.168.0.45

# Set a custom port for the node to node communication (9300 by default):
#
transport.tcp.port: 9302

# Enable compression for all communication between nodes (disabled by default):
#
#transport.tcp.compress: true

# Set a custom port to listen for HTTP traffic:
#
http.port: 9202

# Set a custom allowed content length:
#
#http.max_content_length: 100mb

# Disable HTTP completely:
#
#http.enabled: false


################################### Gateway ###################################

# The gateway allows for persisting the cluster state between full cluster
# restarts. Every change to the state (such as adding an index) will be stored
# in the gateway, and when the cluster starts up for the first time,
# it will read its state from the gateway.

# There are several types of gateway implementations. For more information, see
# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/modules-gateway.html>.

# The default gateway type is the "local" gateway (recommended):
#
#gateway.type: local

# Settings below control how and when to start the initial recovery process on
# a full cluster restart (to reuse as much local data as possible when using shared
# gateway).

# Allow recovery process after N nodes in a cluster are up:
#
#gateway.recover_after_nodes: 1

# Set the timeout to initiate the recovery process, once the N nodes
# from previous setting are up (accepts time value):
#
#gateway.recover_after_time: 5m

# Set how many nodes are expected in this cluster. Once these N nodes
# are up (and recover_after_nodes is met), begin recovery process immediately
# (without waiting for recover_after_time to expire):
#
#gateway.expected_nodes: 2


############################# Recovery Throttling #############################

# These settings allow to control the process of shards allocation between
# nodes during initial recovery, replica allocation, rebalancing,
# or when adding and removing nodes.

# Set the number of concurrent recoveries happening on a node:
#
# 1. During the initial recovery
#
#cluster.routing.allocation.node_initial_primaries_recoveries: 4
#
# 2. During adding/removing nodes, rebalancing, etc
#
#cluster.routing.allocation.node_concurrent_recoveries: 2

# Set to throttle throughput when recovering (eg. 100mb, by default 20mb):
#
#indices.recovery.max_bytes_per_sec: 20mb

# Set to limit the number of open concurrent streams when
# recovering a shard from a peer:
#
#indices.recovery.concurrent_streams: 5


################################## Discovery ##################################

# Discovery infrastructure ensures nodes can be found within a cluster
# and master node is elected. Multicast discovery is the default.

# Set to ensure a node sees N other master eligible nodes to be considered
# operational within the cluster. This should be set to a quorum/majority of 
# the master-eligible nodes in the cluster.
#
discovery.zen.minimum_master_nodes: 2
#最小具有master資格的節點
# Set the time to wait for ping responses from other nodes when discovering.
# Set this option to a higher value on a slow or congested network
# to minimize discovery failures:
#
discovery.zen.ping.timeout: 30s
#超時時間


# For more information, see
# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/modules-discovery-zen.html>

# Unicast discovery allows to explicitly control which nodes will be used
# to discover the cluster. It can be used when multicast is not present,
# or to restrict the cluster communication-wise.
#
# 1. Disable multicast discovery (enabled by default):
#
discovery.zen.ping.multicast.enabled: false
#關閉多播發現節點

#
# 2. Configure an initial list of master nodes in the cluster
#    to perform discovery when new nodes (master or data) are started:
#
discovery.zen.ping.unicast.hosts: ["192.168.0.45:9300","192.168.0.45:9301","192.168.0.45:9302"]
#集羣中的其餘節點信息，默認端口爲9300
# EC2 discovery allows to use AWS EC2 API in order to perform discovery.
#
# You have to install the cloud-aws plugin for enabling the EC2 discovery.
#
# For more information, see
# <http://elasticsearch.org/guide/en/elasticsearch/reference/current/modules-discovery-ec2.html>
#
# See <http://elasticsearch.org/tutorials/elasticsearch-on-ec2/>
# for a step-by-step tutorial.

# GCE discovery allows to use Google Compute Engine API in order to perform discovery.
#
# You have to install the cloud-gce plugin for enabling the GCE discovery.
#
# For more information, see <https://github.com/elasticsearch/elasticsearch-cloud-gce>.

# Azure discovery allows to use Azure API in order to perform discovery.
#

 5.拷貝配置好的node3目錄爲node1，node2並根據步驟4修改elasticsearch.yml

cp -r elasticsearch-node3/ elasticsearch-node1
cp -r elasticsearch-node3/ elasticsearch-node2

6.修改好node1，node2的配置文件後，依次啓動

/root/elasticsearch-node1/bin/elasticsearch -d -Xms512m -Xmx512m
/root/elasticsearch-node2/bin/elasticsearch -d -Xms512m -Xmx512m
/root/elasticsearch-node3/bin/elasticsearch -d -Xms512m -Xmx512m

7.檢查啓動狀態

[root@localhost ~]# ps -ef | grep elasticsearch
root       1892      1 26 16:32 pts/0    00:00:10 /root/jdk/bin/java -Xms256m -Xmx1g -Djava.awt.headless=true -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+HeapDumpOnOutOfMemoryError -XX:+DisableExplicitGC -Dfile.encoding=UTF-8 -Delasticsearch -Des.path.home=/root/elasticsearch-node1 -cp :/root/elasticsearch-node1/lib/elasticsearch-1.7.3.jar:/root/elasticsearch-node1/lib/*:/root/elasticsearch-node1/lib/sigar/* -Xms512m -Xmx512m org.elasticsearch.bootstrap.Elasticsearch

8.集羣的中止：能夠經過以下命令關閉集羣全部節點

curl -XPOST http://192.168.0.45:9200/_cluster/nodes/_shutdown

 

9. 安裝可視化插件

BigDesk Plugin : 對集羣中es狀態進行監控。 
Elasticsearch Head Plugin: 對ES進行各類操做，如查詢、刪除、瀏覽索引等

cd /root/elasticsearch-node1/bin
./plugin -install mobz/elasticsearch-head
./plugin -install lukas-vlcek/bigdesk

 

10.打開瀏覽器，輸入地址 http://192.168.0.45:9200/_plugin/head/

能夠看見節點信息以及相關的操做

經過頁面添加

經過get方式獲取

再返回首頁查看

 

所有的數據能夠經過數據瀏覽來看，能看到索引、類型、字段已經對應的值

 

另外須要補充下，經過命令put數據進去各層級分別表明什麼

如經過下列命令：

http://192.168.0.45:9200/databasename/tableName/primaryKey

{
  "title": "database data demo",
  "tableName": "users",
  "columns": {
    "userId": "1",
    "username": "xiaochangwei",
    "email": "changw.xiao@qq.com",
    "age": "30",
    "birthday": "1987-09-23",
    "location": "chengdu tianfu software park"
  },
  "createTime": "2017-02-14 08:24:00"
}

url中三層能夠理解爲mysql中的數據庫，表名，還有主鍵， 之後搜索的時候就按照這個順序來搜索了，意思就是這個意思，表達很差 很差意思

再羅嗦一句， databasename必須爲小寫 

另外，我這裏加入的是複合字段，即columns裏面又包含了多個字段，elasticsearch中這樣用的時候特多，存儲時，是按 父字段.子字段方式存的， 如：

 

更多命令請參考elasticsearch使用指南，或者參考 http://blog.csdn.net/tanfei113/article/details/51934037

 

後續會在springboot+springCloud系列學習內容中依次展現主流工具的使用

部分代碼已經提交到git上了，請參考頂部地址獲取，有不對的地方請指正

 

-------------------------------------------------------------------------

在springboot中使用elasticsearch的時候，用上述安裝的1.7.3版本始終連接不上，後來發現是springboot 1.5.3.RELEASE 和1.7.3 版本不匹配 https://github.com/spring-projects/spring-data-elasticsearch/wiki/Spring-Data-Elasticsearch---Spring-Boot---version-matrix

故安裝了2.3.3版本的，安裝方式和上面相似，就簡單的記錄下了

cd /usr/src
wget https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/zip/elasticsearch/2.3.3/elasticsearch-2.3.3.zip
unzip elasticsearch-2.3.3.zip

  mv elasticsearch-2.3.3 elasticsearch-2.3.3-node1
  cp -ri elasticsearch-2.3.3-node1 elasticsearch-2.3.3-node2
