搞了2天终于搞好了
更新:
2017/2/15: 更改elasticsearch.yml中绑定ip, 可开启集群效果 2017/2/16: supervisord.conf 加入 autostart=true, 开启景象自动启动
2017/2/16: 更改elasticsearch.yml中ip嗅探, 真正实现热插拔集群
bug: 指定的物理机挂在目录仍然存在问题
需要: 一个能在linux下正常运行的 elasticsearch-2.4.0 版本, 直接copy进镜像, 安装好head, bigdesk, ik分词 器等, 在elasticsearch中有讲: http://www.cnblogs.com/wenbronk/p/6390462.html

# ======================== Elasticsearch Configuration ========================= # # NOTE: Elasticsearch comes with reasonable defaults for most settings. # Before you set out to tweak and tune the configuration, make sure you # understand what are you trying to accomplish and the consequences. # # The primary way of configuring a node is via this file. This template lists # the most important settings you may want to configure for a production cluster. # # Please see the documentation for further information on configuration options: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html> # # ---------------------------------- Cluster ----------------------------------- # # Use a descriptive name for your cluster: # cluster.name: wenbronk-escluster # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # # node.name: wenbronk-esnode01 # # Add custom attributes to the node: # # node.rack: r1 # # ----------------------------------- Paths ------------------------------------ # # Path to directory where to store the data (separate multiple locations by comma): # # path.data: /escluster/data path.data: /escluster/data # # # # Path to log files: # # path.logs: /escluster/logs # # Path to log files: # # path.logs: /escluster/logs # # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # # bootstrap.memory_lock: true # # Make sure that the `ES_HEAP_SIZE` environment variable is set to about half the memory # available on the system and that the owner of the process is allowed to use this limit. # # Elasticsearch performs poorly when the system is swapping the memory. # # ---------------------------------- Network ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # network.host: 0.0.0.0 # # Set a custom port for HTTP: # http.port: 9200 # # For more information, see the documentation at: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html> # # --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when new node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # discovery.zen.ping.unicast.hosts: ["192.168.1.110", "[::1]"] # # Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1): # # discovery.zen.minimum_master_nodes: 3 # # For more information, see the documentation at: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery.html> # # ---------------------------------- Gateway ----------------------------------- # # Block initial recovery after a full cluster restart until N nodes are started: # # gateway.recover_after_nodes: 3 # # For more information, see the documentation at: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-gateway.html> # # ---------------------------------- Various ----------------------------------- # # Disable starting multiple nodes on a single system: # # node.max_local_storage_nodes: 1 # # Require explicit names when deleting indices: # # action.destructive_requires_name: true index.analysis.analyzer.ik.type: ik
创建镜像:
docker build -t wenbronk/jdk8u121/escluster .
注: 因为es使用非root账户, docker默认使用root账户, 开启一直不成功, supervisord还没来及学, 所以暂时使用root开启es
vim ./bin/elasticsearch
插入
-Des.insecure.allow.root="true"
启动
docker run -d -p 9990:22 -p 9200:9200 -p 9300:9300 -v /docker/escluster01:/esculster wenbronk/jdk8u121/escluster docker run -d -p 9991:22 -p 9201:9200 -p 9301:9300 -v /docker/escluster01:/esculster wenbronk/jdk8u121/escluster docker run -d -p 9992:22 -p 9202:9200 -p 9302:9300 -v /docker/escluster01:/esculster wenbronk/jdk8u121/escluster
