elasticsearch集群搭建手册（伪集群搭建）

安装部署

---

建立程序目录

1. 安装目录

mkdir /usr/local/elasticsearch
mkdir /usr/local/elasticsearch/6.4.3
mkdir /usr/local/elasticsearch/6.4.3/01     #第一个节点
mkdir /usr/local/elasticsearch/6.4.3/02     #第二个节点
mkdir /usr/local/elasticsearch/6.4.3/03     #第三个节点

2. 数据目录

mkdir /data
mkdir /data/elasticsearch
mkdir /data/elasticsearch/01
mkdir /data/elasticsearch/01/data
mkdir /data/elasticsearch/01/logs
mkdir /data/elasticsearch/02
mkdir /data/elasticsearch/02/data
mkdir /data/elasticsearch/02/logs
mkdir /data/elasticsearch/03
mkdir /data/elasticsearch/03/data
mkdir /data/elasticsearch/03/logs

3. 下载程序

3.1 下载Elasticsearch 6.4.3 tar

curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.3.tar.gz

3.2 解压文件

tar -xvf elasticsearch-6.4.3.tar.gz
cd elasticsearch-6.4.3/
cp -rf * /usr/local/elasticsearch/6.4.3/01/
cp -rf * /usr/local/elasticsearch/6.4.3/02/
cp -rf * /usr/local/elasticsearch/6.4.3/03/

修改配置文件

1. 01节点 vi /usr/local/elasticsearch/6.4.3/01/config/elasticsearch.yml

# ---------------------------------- Cluster -----------------------------------
#这个填写集群名称，集群中每一个节点的名称必须一致，es节点是经过名称才来肯定是不是同一个集群的
cluster.name: es-test
# ------------------------------------ Node ------------------------------------
#配置当前节点的名称，该名称在集群中惟一，不可重复
node.name: node01
# ----------------------------------- Paths ------------------------------------
path.data: /data/elasticsearch/01/data
path.logs: /data/elasticsearch/01/logs
# ----------------------------------- Memory -----------------------------------
#用于程序启动时建设内存是否足够存放heap size，测试版能够设成false
bootstrap.memory_lock: true
# ---------------------------------- Network -----------------------------------
#绑定IP地址
network.host: 0.0.0.0
#默认端口9200， 注：9300为es节点间TCP通信使用，配置是请勿占用
http.port: 9201
# --------------------------------- Discovery ----------------------------------
#集群最小主节点数，为了防止脑裂，主节点数必须为奇数个，正式版建议采用 “总节点数/2 + 1”
discovery.zen.minimum_master_nodes: 1

2. 02节点 $ vi /usr/local/elasticsearch/6.4.3/02/config/elasticsearch.yml

# ---------------------------------- Cluster -----------------------------------
#这个填写集群名称，集群中每一个节点的名称必须一致，es节点是经过名称才来肯定是不是同一个集群的

3. 03节点 $ vi /usr/local/elasticsearch/6.4.3/03/config/elasticsearch.yml

# ----------------------------------- Memory -----------------------------------
#用于程序启动时建设内存是否足够存放heap size，测试版能够设成flase
bootstrap.memory_lock: true
# ---------------------------------- Network -----------------------------------
#绑定IP地址
network.host: 0.0.0.0
#默认端口9200， 注：9300为es节点间TCP通信使用，配置是请勿占用

# --------------------------------- Discovery ----------------------------------
#集群最小主节点数，为了防止脑裂，正式版建议采用 “总节点数/2 + 1”
discovery.zen.minimum_master_nodes: 1

部署隔离完善

---

1. 建立运行帐户

groupadd elastic
useradd -g elastic elasticsearch

2. 修改目录权限

chown -R elasticsearch:elastic /data/elasticsearch
chown -R /usr/local/elasticsearch/6.4.3

3. 添加supervisor守护 $ vi /etc/supervisor/conf.d/elasticsearch.conf

[program:elasticsearch01]
command=/usr/local/elasticsearch/6.4.3/01/bin/elasticsearch
autostart=true
autorestart=true
startsecs=3
user=elasticsearch
redirect_stderr=true
stdout_logfile=/var/logs/supervisor/elasticsearch01.log
stdout_logfile_maxbytes=10MB
stdout_logfile_backups=10
[program:elasticsearch02]
command=/usr/local/elasticsearch/6.4.3/02/bin/elasticsearch
autostart=true
autorestart=true
startsecs=3
user=elasticsearch
redirect_stderr=true
stdout_logfile=/var/logs/supervisor/elasticsearch02.log
stdout_logfile_maxbytes=10MB
stdout_logfile_backups=10
[program:elasticsearch03]
command=/usr/local/elasticsearch/6.4.3/03/bin/elasticsearch
autostart=true
autorestart=true
startsecs=3
user=elasticsearch
redirect_stderr=true
stdout_logfile=/var/logs/supervisor/elasticsearch03.log
stdout_logfile_maxbytes=10MB
stdout_logfile_backups=10
