安裝部署

建立程式目錄

1. 安裝目錄

mkdir /usr/local/elasticsearch
mkdir /usr/local/elasticsearch/6.4.3
mkdir /usr/local/elasticsearch/6.4.3/01     #第一個節點
mkdir /usr/local/elasticsearch/6.4.3/02     #第二個節點
mkdir /usr/local/elasticsearch/6.4.3/03     #第三個節點

2. 資料目錄

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. 下載程式

3.1 下載Elasticsearch 6.4.3 tar

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

3.2 解壓檔案

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/
 

修改配置檔案

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

# ---------------------------------- Cluster -----------------------------------
#這個填寫叢集名稱，叢集中每個節點的名稱必須一致，es節點是通過名稱才來確定是否是同一個叢集的
cluster.name: es-test
# ------------------------------------ Node ------------------------------------
#配置當前節點的名稱，該名稱在叢集中唯一，不可重複
node.name: node01
# ----------------------------------- Paths ------------------------------------
path.data: /data/elasticsearch/01/data
path.logs: /data/elasticsearch/01/logs
# ----------------------------------- Memory -----------------------------------
#用於程式啟動時建設記憶體是否足夠存放heap size，測試版可以設成false
bootstrap.memory_lock: true
# ---------------------------------- Network -----------------------------------
#繫結IP地址
network.host: 0.0.0.0
#預設埠9200， 注：9300為es節點間TCP通訊使用，配置是請勿佔用
http.port: 9201
# --------------------------------- Discovery ----------------------------------
#叢集最小主節點數，為了防止腦裂，主節點數必須為奇數個，正式版建議採用 “總節點數/2 + 1”
discovery.zen.minimum_master_nodes: 1
 

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

# ---------------------------------- Cluster -----------------------------------
#這個填寫叢集名稱，叢集中每個節點的名稱必須一致，es節點是通過名稱才來確定是否是同一個叢集的
cluster.name: es-test
# ------------------------------------ Node ------------------------------------
#配置當前節點的名稱，該名稱在叢集中唯一，不可重複
node.name: node02
# ----------------------------------- Paths ------------------------------------
path.data: /data/elasticsearch/02/data
path.logs: /data/elasticsearch/02/logs
# ----------------------------------- Memory -----------------------------------
#用於程式啟動時建設記憶體是否足夠存放heap size，測試版可以設成false
bootstrap.memory_lock: true
# ---------------------------------- Network -----------------------------------
#繫結IP地址
network.host: 0.0.0.0
#預設埠9200， 注：9300為es節點間TCP通訊使用，配置是請勿佔用
http.port: 9202
# --------------------------------- Discovery ----------------------------------
#叢集最小主節點數，為了防止腦裂，正式版建議採用 “總節點數/2 + 1”
discovery.zen.minimum_master_nodes: 1

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

# ---------------------------------- Cluster -----------------------------------
#這個填寫叢集名稱，叢集中每個節點的名稱必須一致，es節點是通過名稱才來確定是否是同一個叢集的
cluster.name: es-test
# ------------------------------------ Node ------------------------------------
#配置當前節點的名稱，該名稱在叢集中唯一，不可重複
node.name: node03
# ----------------------------------- Paths ------------------------------------
path.data: /data/elasticsearch/03/data
path.logs: /data/elasticsearch/03/logs
# ----------------------------------- Memory -----------------------------------
#用於程式啟動時建設記憶體是否足夠存放heap size，測試版可以設成flase
bootstrap.memory_lock: true
# ---------------------------------- Network -----------------------------------
#繫結IP地址
network.host: 0.0.0.0
#預設埠9200， 注：9300為es節點間TCP通訊使用，配置是請勿佔用
http.port: 9203
# --------------------------------- Discovery ----------------------------------
#叢集最小主節點數，為了防止腦裂，正式版建議採用 “總節點數/2 + 1”
discovery.zen.minimum_master_nodes: 1

部署隔離完善

1. 建立執行賬戶

groupadd elastic
useradd -g elastic elasticsearch

2. 修改目錄許可權

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

3. 新增supervisor守護 $ 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]

autostart=true
autorestart=true
startsecs=3
