elasticsearch6.x叢集環境部署

elasticsearch叢集部署

安裝jdk

chmod 755 jdk-8u161-linux-x64.tar.gz
tar -zxvf jdk-8u161-linux-x64.tar.gz
cp jdk1.8.0_161 /data/install
           

建立elasticsearch執行使用者

useradd elastic
mkdir /data/install/elastic
chmod -R 777 /data/install/elastic
           

安裝elasticsearch-head插件

yum -y install nodejs
yum -y install yum-utils
yum -y install openssl
yum -y update openssl
yum-config-manager --enable cr
yum update

mkdir /data/install/nodejs
npm config set prefix "/data/install/nodejs"
npm install -g grunt
cp /data/ftp/elasticsearch-head-master.zip /data/install/elastic
unzip /data/install/elastic/elasticsearch-head-master.zip
cd /data/install/elastic/elasticsearch-head-master
npm install

啟動服務
grunt server &
           

安裝elasticsearch

cp /data/ftp/elasticsearch-6.2.4.tar.gz /data/install/elastic
su elastic
cd /data/install/elastic
tar -zxvf elasticsearch-6.2.4.tar.gz

1.配置master node
	cluster.name: qsearch
	node.name: qsearch-master
	node.data: false
	node.master: true
	path.data: /data/install/elastic/data
	path.logs: /data/install/elastic/logs
	network.host: 本機内網ip
	# 本機ip或其他叢集中機器的ip，随便寫幾個就行，不用全寫，隻要有一台機連上，就# 能自動加入叢集
	discovery.zen.ping.unicast.hosts: ['host1', 'host2', ...]
	# 防止腦裂
	discovery.zen.minimum_master_nodes: number of master-nodes / 2 + 1

2.配置client node
	cluster.name: qsearch
	node.name: qsearch-client
	node.data: false
	node.master: false
	path.data: /data/install/elastic/data
	path.logs: /data/install/elastic/logs
	network.host: 本機内網ip
	discovery.zen.ping.unicast.hosts: ['host1', 'host2', ...]

3.配置data node
	cluster.name: qsearch
	node.name: qsearch-data
	node.data: false
	node.master: false
	path.data: /data/install/elastic/data
	path.logs: /data/install/elastic/logs
	network.host: 本機内網ip
	discovery.zen.ping.unicast.hosts: ['host1', 'host2', ...]
	bootstrap.mlockall: true
           

系統配置

以下是data node必配，其他的參考：https://blog.csdn.net/iorichang/article/details/53840824

vim /etc/security/limits.conf
	elastic soft nofile 65536
	elastic hard nofile 65536
	elastic soft memlock unlimited
	elastic hard memlock unlimited

vim /etc/sysctl.conf
	vm.swappiness=1 # 關閉 swapping
	net.core.somaxconn=65535 # 上調端口的最大連接配接數
	vm.max_map_count=262144
	fs.file-max=518144
           

安裝分詞+拼音插件

源碼編譯安裝：
1.安裝maven
2.解壓
elasticsearch-analysis-ik-6.2.4.source.zip
elasticsearch-analysis-pinyin-master.source.zip
3.進入解壓目錄，輸入mvn clean package 編譯
4.編譯結果在:/target/releases/XXXX.zip
5.安裝插件：elasticsearch-plugin install /target/releases/xxxx.zip

也可以已經編譯好的插件zip包，直接安裝就可以
