什么是ES？ElasticSearch是一个基于Lucene的搜索服务器。它提供了一个分布式多用户能力的全文搜索引擎，基于RESTful web接口。Elasticsearch是用Java语言开发的，并作为Apache许可条款下的开放源码发布，是一种流行的企业级搜索引擎。ElasticSearch用于云计算中，能够达到实时搜索，稳定，可靠，快速，安装使用方便。

本教程使用软件为6.4.3版本

解压并修改配置文件

# 注意：需要使用普通用户操作ES，不可使用root用户进行操作。#使用root用户，添加用户 #添加用户命令： [root@hadoop137 ~]# useradd shaofei [root@hadoop137 ~]# passwd shaofei 更改用户 shaofei的密码。新的密码：无效的密码：过于简单化/系统化无效的密码：过于简单重新输入新的密码： passwd：所有的身份验证令牌已经成功更新。#切换为shaofei用户： [root@hadoop137 ~]# su shaofei [shaofei@hadoop137 root]$ cd [shaofei@hadoop137 ~]$ # 解压elasticsearch [shaofei@hadoop137 softwear]$ tar -zxvf elasticsearch-6.4.3.tar.gz -C ../module/ [shaofei@hadoop137 elasticsearch-6.4.3]$ pwd /opt/module/elasticsearch-6.4.3# 修改配置文件 [shaofei@hadoop137 elasticsearch-6.4.3]$ vim config/elasticsearch.yml # 注意修改yml文件时，配置项后面要空格

elasticsearch.yml

# ======================== 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 consult the documentation for further information on configuration options: # https://www.elastic.co/guide/en/elasticsearch/reference/index.html # # ---------------------------------- Cluster ----------------------------------- # # Use a descriptive name for your cluster: # 修改集群名称 cluster.name: myes # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # 修改当前节点名称——下一步分发到其他集群时需要修改 node.name: hadoop137 # # Add custom attributes to the node: # #node.attr.rack: r1 # # ----------------------------------- Paths ------------------------------------ # # Path to directory where to store the data (separate multiple locations by comma): # #path.data: /path/to/data # # Path to log files: # #path.logs: /path/to/logs # # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # #bootstrap.memory_lock: true # # Make sure that the heap size 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): # 当前节点的ip地址，我这里配置了hosts文件所以写了主机名称——下一步分发之后需要修改为对应主机的ip地址 network.host: hadoop137 # # Set a custom port for HTTP: # ES对外开放服务的端口号 http.port: 9200 # # For more information, consult the network module documentation. # # --------------------------------- 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: ["host1", "host2"] # # Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1): # #discovery.zen.minimum_master_nodes: # # For more information, consult the zen discovery module documentation. # # ---------------------------------- Gateway ----------------------------------- # # Block initial recovery after a full cluster restart until N nodes are started: # #gateway.recover_after_nodes: 3 # # For more information, consult the gateway module documentation. # # ---------------------------------- Various ----------------------------------- # # Require explicit names when deleting indices: # #action.destructive_requires_name: true#添加集群ip地址 discovery.zen.ping.unicast.hosts: ["192.168.23.137", "192.168.23.138", "192.168.23.139"]

分发各个集群中的其他主机

[shaofei@hadoop137 module]$ rsync -rvl elasticsearch-6.4.3 shaofei@hadoop138:`pwd` [shaofei@hadoop137 module]$ rsync -rvl elasticsearch-6.4.3 shaofei@hadoop139:`pwd`

分别启动集群中的ES

[shaofei@hadoop137 elasticsearch-6.4.3]$ ./bin/elasticsearch[shaofei@hadoop138 elasticsearch-6.4.3]$ ./bin/elasticsearch[shaofei@hadoop139 elasticsearch-6.4.3]$ ./bin/elasticsearch

启动中遇到的问题：

ERROR: [4] bootstrap checks failed

[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]

[2]: max number of threads [1024] for user [shaofei] is too low, increase to at least [4096]

[3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

对于第【1】个问题： [root@hadoop139 shaofei]# vi /etc/security/limits.conf 末尾添加： # End of file* soft nofile 65536* hard nofile 131072* soft nproc 2048* hard nproc 4096对于第【2】个问题： [root@hadoop139 shaofei]# vim /etc/security/limits.d/90-nproc.conf 修改： [root@hadoop139 shaofei]# cat /etc/security/limits.d/90-nproc.conf # Default limit for number of user's processes to prevent # accidental fork bombs. # See rhbz #432903 for reasoning.* soft nproc 10240 root soft nproc unlimited# 重新登陆用户即可对于第【3】个问题： vi /etc/sysctl.conf 添加下面配置： vm.max_map_count=655360并执行命令： sysctl -p

java.lang.UnsupportedOperationException: seccomp unavailable: CONFIG_SECCOMP not compiled into kernel, CONFIG_SECCOMP and CONFIG_SECCOMP_FILTER are needed

# 修改elasticsearch.yml 添加一下内容bootstrap.memory_lock: false bootstrap.system_call_filter: false

问题解决之后重新启动es即可。
