安装ElasticSearch

Docker安装ElasticSearch

1、拉取镜像

docker pull elasticsearch:7.4.1

2、创建自定义网络

docker network create hahanetwork

3、创建容器并运行

docker run --name elasticsearch --net hahanetwork -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -d elasticsearch:7.4.1

Linux安装ElasticSearch

1、环境准备

安装jdk1.8，es不允许直接以root用户运行，创建用户es,设置密码也是es

groupadd elasticsearch

useradd es -g elasticsearch -p es

chown -R es:elasticsearch  elasticsearch-6.4.3

2、上传安装包，并解压，给用户es操作文件的权限

[root@localhost etc]# tar -zxvf elasticsearch-6.4.3.tar.gz 
[root@localhost etc]# chown -R es elasticsearch-6.4.3/

3、先修改配置，解除注释

　　network.host: 192.168.10.102

　　http.port: 9200

[root@localhost local]# vi elasticsearch-6.4.3/config/elasticsearch.yml

4、进入bin目录启动es

[root@localhost etc]# cd elasticsearch-6.4.3/bin/
[root@localhost bin]# su es
[es@localhost bin]$ nohup ./bin/elasticsearch > /dev/null 2> 1 &

 5、启动报错

#报错  bootstrap checks failed max virtual memory areas vm.max_map_count [65530] is

vi /etc/sysctl.conf

vm.max_map_count=655360

sysctl p


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

vi /etc/security/limits.conf

* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096

ES集群配置：

vi elasticsearch.yml

###保证三台服务器节点集群名称相同
cluster.name: myes 
#### 每个节点名称不一样 其他两台为node-1 ,node-2
node.name: node-1 
#### 实际服务器ip地址
network.host: 192.168.212.180 
##多个服务集群ip
discovery.zen.ping.unicast.hosts: ["192.168.212.184", "192.168.212.185","192.168.212.186"]
discovery.zen.minimum_master_nodes: 1
