【ES实战】ES6.7的tar包离线安装帮助手册

Elasticsearch6.7部署帮助手册

校验时间：2023年12月19日

安装前准备

安装包

• elasticsearch-6.7.2.tar.gz
• elasticsearch-analysis-dynamic-synonym-6.7.2.zip
• elasticsearch-analysis-ik-6.7.2.zip
• elasticsearch-analysis-pinyin-6.7.2.zip
• jdk1.8.0_161.tgz

插件安装参考：ES插件安装帮助说明

安装要求

命令netstat -lntp 2>/dev/null|grep LISTEN|awk '{print $4}'|awk -F':' '{print $NF}'|sort|uniq查询已经占用的端口

机器要求与大数据机器模板相同

以下是补充：

锁定内存,修改最大文件描述符,最大线程数

vim /etc/security/limits.d/90-nproc.conf

确保：

nproc >= 20480
nofile >= 65536

增加：

* - memlock unlimited

内核参数

vim /etc/sysctl.conf

确保增加以下参数配置：

vm.zone_reclaim_mode = 0
net.ipv4.ip_local_reserved_ports=9500-9702
net.ipv4.ip_local_port_range = 10000 65000
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw_reuse = 1
vm.swappiness=0
vm.overcommit_memory=1
vm.zone_reclaim_mode=0
vm.max_map_count=262144

更改内核后完成后执行命令：sysctl -p生效

部署规划

采用master与data分离部署方式

集群A

服务器Host	master	data	Cluster
es01	yes	yes	A
es02	yes	yes	A
es03	yes	yes	A

集群B

服务器Host	master	data	Cluster
es04	yes	yes	B
es05	yes	yes	B
es06	yes	yes	B

端口规划

纯master角色节点：TCP端口：9201，HTTP端口：9200。

纯data角色节点：TCP端口：9301，HTTP端口：9300。

用户规划

groupadd -g 750 es;
useradd -u 750 -g 750 es;

目录规划

将空间大的目录软链接到home的子目录下，比如/opt或者/data。此文档采用/data目录为例：

• 用户目录

  /home/es/software 链接至 /data/elasticsearch/software

• 数据目录

  /home/es/data链接至 /data/elasticsearch/data

• 日志目录

  /home/es/logs链接至 /data/elasticsearch/logs

安装步骤

在操作之前安装包已经分发到各个服务器的/data/install_package目录。权限为755。

root命令执行命令

chmod 755 -R /data/install_package/
# 1.新建用户与用户组
groupadd -g 750 es;
useradd -u 750 -g 750 es;
# 2.准备目录
mkdir -p /data/elasticsearch;
chown -R es:es /data/elasticsearch/;

以下开始使用es用户执行命令

su - es;
mkdir -p /data/elasticsearch/software;
mkdir -p /data/elasticsearch/logs;
mkdir -p /data/elasticsearch/data;
# master的元数据存储目录
mkdir -p /data/elasticsearch/masterdata;
ln -snf /data/elasticsearch/software /home/es/software;
ln -snf /data/elasticsearch/logs /home/es/logs;
ln -snf /data/elasticsearch/masterdata /home/es/masterdata;
# master角色节点的配置文件目录
mkdir -p /home/es/software/config-master;
# node角色节点的配置文件目录
mkdir -p /home/es/software/config-dnode0;

# 3.将安装包解压至software目录并配置软链接
tar -zxf /data/install_package/jdk1.8.0_161.tgz -C /home/es/software/;
tar -zxf /data/install_package/elasticsearch-6.7.2.tar.gz -C /home/es/software/;
ln -snf /home/es/software/jdk1.8.0_161 /home/es/software/java;
ln -snf /home/es/software/elasticsearch-6.7.2 /home/es/software/elasticsearch;

每个服务器配置JDK

su - es;
vim /home/es/.bashrc;
# 在.bashrc文件中追加以下内容
export JAVA_HOME=/home/es/software/java
export PATH=$JAVA_HOME/bin:$PATH

# 配置生效
source /home/es/.bashrc;
# 检查jdk
java -version;

启动与停止

es-daemon.sh并非官网脚本。

启动

首次启动

先启动所有的master，在启动dnode1

su - es;
cd /home/es/software/elasticsearch/bin/;
sh es-daemon.sh start master;


su - es;
cd /home/es/software/elasticsearch/bin/;
sh es-daemon.sh start dnode0

检查

查询节点是否正常

curl 'http://ip:http端口'
curl 'http://192.168.1.1:9200'

如果返回

{
  "name" : "192.168.1.1-dnode0",
  "cluster_name" : "demo-ccr-1",
  "cluster_uuid" : "CjcavbOjQPeymec-GOJgVA",
  "version" : {
    "number" : "6.7.2",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "Unknown",
    "build_date" : "Unknown",
    "build_snapshot" : true,
    "lucene_version" : "7.7.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

则表示启动成功，其余情况，则可能存在问题。

查询集群整体健康

curl 'http://192.168.1.1:9200/_cat/health?v'

如果返回值中：status值为green，则表示启动成功，其余情况，则可能存在问题

停止

su - es;
cd /home/es/software/elasticsearch/bin/;
sh es-daemon.sh stop master

su - es;
cd /home/es/software/elasticsearch/bin/;
sh es-daemon.sh stop dnode1
