CentOS7.3安装elasticsearch6.8.6 - 简书
##1.1 下载安装elasticsearch6.8.6, 并放到/usr/local/src/目录后
cd /usr/local/src/
unzip elasticsearch-6.8.6.zip
vim /usr/local/src/elasticsearch-6.6.2/config/elasticsearch.yml
##1.2 修改jvm.options
vim /usr/local/src/elasticsearch-6.8.6/config/jvm.options
————————————————
22行:-Xms1g ———>-Xms512m
23行:-Xmx1g ———>-Xmx512m
————————————————
##1.2 修改elasticsearch.yml
vim /usr/local/src/elasticsearch-6.8.6/config/elasticsearch.yml
————————————————
17行:设置cluster.name: elasticsearch(自定义集群名称)
23行:设置node.name: master(自定义当前es的节点名称)
43行:设置
bootstrap.network.host: 0.0.0.0
bootstrap.memory_lock: false
44行:设置bootstrap.system_call_filter: false
56行: network.host: 0.0.0.0 (设置当前节点的IP)
60行: 设置端口号 http.port: 9200
xpack.ml.enabled: false
network.host: 0.0.0.0
http.port: 9200
#内存
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
#允许跨域
http.cors.enabled: true
http.cors.allow-origin: "*"
#集群和节点
cluster.name: elasticsearch-cluster
node.name: master
node.master: true
————————————————
##2.下载安装elasticsearch插件
/usr/local/src/elasticsearch-6.8.6/bin/elasticsearch-plugin install analysis-icu
/usr/local/src/elasticsearch-6.8.6/bin/elasticsearch-plugin list
##3.新建es账户
groupadd elasticsearch
useradd -g elasticsearch elasticsearch
chown -R elasticsearch:elasticsearch /usr/local/src/elasticsearch-6.8.6/
##4.修改配置
vi /etc/security/limits.conf
##4.启动elasticsearch
su elasticsearch
#4.1直接启动
/usr/local/src/elasticsearch-6.8.6/bin/elasticsearch
#4.2后台启动
/usr/local/src/elasticsearch-6.8.6/bin/elasticsearch -d
启动报错信息1: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
root 用户:vi /etc/sysctl.conf 添加 vm.max_map_count=262144:保存退出之后,执行命令 sysctl -p
启动报错信息2:max number of threads is too low
root 用户:vi /etc/security/limits.conf 在文件最后添加
* soft nofile 65536
* hard nofile 65536
* soft nproc 4096
* hard nproc 4096
启动报错信息3: max number of threads [1024] for user [elasticsearch] is too low, increase to at least [4096]
vi /etc/security/limits.d/90-nproc.conf 改为4096
修改完记得退出elasticsearch 用户再进
java1.8+
下载地址:
解压elasticsearch-6.8.6.tar.gz
tar -zxvf elasticsearch-6.8.6.tar.gz
启动es必须创建用户,不能使用root启动
useradd esuser
分配权限
chown -R esuser elasticsearch-6.8.6(安装的es目录)
1、vim elasticsearch-6.8.6/conf/jvm.options
22行:-Xms1g ———>-Xms512m
23行:-Xmx1g ———>-Xmx512m
2、vim elasticsearch-6.8.6/conf/elasticsearch.yml
17行:设置cluster.nam: elasticsearch(自定义集群名称)
23行:设置node.name: node-1(自定义当前es的节点名称)
43行:设置bootstrap.mnetwork.host: 192.168.1.43emory_lock: false
44行:设置bootstrap.system_call_filter: false
56行: network.host: 192.168.1.43 (设置当前节点的IP)
60行: 设置端口号 http.port: 9200
最后添加:
http.cors.enabled: true
http.cors.allow-origin: "*"
3、此时启动汇报错:ERROR: [2] bootstrap checks failed
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决:编辑 /etc/security/limits.conf,追加以下内容;
* soft nofile 300000
* hard nofile 300000
* soft nproc 102400
* soft memlock unlimited
* hard memlock unlimited
编辑 /etc/sysctl.conf,追加以下内容:
vm.max_map_count=655360
保存,启动 在bin/elasticsearch -d 后台启动
在服务器端: curl http://192.168.1.43:9200
浏览器:http://192.168.1.43:9200
出现以下内容表示成功:
{
"name" : "node-1",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "wwniBniiSeSnl90g2KGaIQ",
"version" : {
"number" : "6.8.6",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "3d9f765",
"build_date" : "2019-12-13T17:11:52.013738Z",
"build_snapshot" : false,
"lucene_version" : "7.7.2",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
将下载好的分词器压缩包上传至elasticsearch-6.8.6/plugins目录下,解压重启es即可
