https://github.com/medcl/elasticsearch-analysis-ik/releases/tag/v7.10.1--------------------------- 安装es, 并安装插件elasticsearch-analysis-ik ----------------------------
1.官网下载elasticsearch,选择自己需要的版本(备注:es,kibana,ik等版本要统一)https://www.elastic.co/cn/downloads/past-releases/elasticsearch-7-10-1
2.解压到自己存放的目录
1)cd /usr/local
2)tar -zxvf elasticsearch-7.10.1-linux-x86_64.tar.gz3.修改配置文件elasticsearch.yml
1)cd /usr/local/elasticsearch-7.10.1
2)mkdir data
3)vim ./config/elasticsearch.yml
cluster.name: my-application #集群名称
node.name: node-1 #节点名称
path.data: /usr/local/elasticsearch-7.10.1/data #数据的存储目录
path.logs: /usr/local/elasticsearch-7.10.1/logs #日志的存储目录
network.host: 0.0.0.0 #设置绑定的ip,设置为0.0.0.0,可以让任何计算机节点访问
http.port: 9200 #端口
cluster.initial_master_nodes: ["node-1"] #设置在集群中的所有节点名称,这个节点名称就是之前所修改的,当然你也可以采用默认的也行,目前是单机,放入一个节点即可4.修改limits.conf文件(myes是启动elasticsearch的账户,elasticsearch是不能再root账户下启动的)
vim /etc/security/limits.conf
myes soft nofile 65536
myes hard nofile 65536
myes soft nproc 4096
myes hard nproc 40965.修改sysctl.conf文件(添加 vm.max_map_count = 655360)
vim /etc/sysctl.conf
文件末尾添加:vm.max_map_count = 655360
***退出文件后执行:sysctl -p看信息是否已经添加上去6.修改/usr/local/elasticsearch-7.10.1/config/jvm.options
1)根据服务器内存设置合适的值
1)cd /usr/local/elasticsearch-7.10.1/config/
2)vim jvm.options添加如下值
-Xms512m
-Xmx512m7.添加用户
不能使用root用户去启动elasticsearch,因为elasticsearch内置的安全性
添加es用户,密码为es,并修改elasticsearch-7.10.1目录的权限:
adduser es -p es
chown -R es /usr/local/elasticsearch-7.10.1/
chown -R es /usr/local/kibana-7.10.1-linux-x86_64/8.上传elasticsearch-analysis-ik-7.10.1.zip插件到/usr/local/elasticsearch-7.10.1/plugins目录下
1)解压
cd /usr/local/elasticsearch-7.10.1/plugins
unzip -d elasticsearch-analysis-ik-7.10.1 elasticsearch-analysis-ik-7.10.1.zip
rm -rf elasticsearch-analysis-ik-7.10.1.zip
2)同步权限
chown -R es ./elasticsearch-analysis-ik-7.10.1
9.启动elasticsearch
-前台启动
1)切换账户:su es
2)启动服务:/usr/local/elasticsearch-7.10.1/bin/elasticsearch
-后台启动:
1)切换账户:su es
2)启动服务:/usr/local/elasticsearch-7.10.1/bin/elasticsearch -d-看日志,去查看启动有无异常:
1)cd /usr/local/elasticsearch-7.10.1/logs
2)tail -f my-application.log10.测试是否启动成功
-网页输入:http://ip:9200/
-服务器上输入:curl 127.0.0.1:9200
返回如下信息,则启动OK:
{
"name" : "node-1",
"cluster_name" : "my-application",
"cluster_uuid" : "RqDrF8pyQfaNTDf_lNf_Ow",
"version" : {
"number" : "7.10.1",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "1c34507e66d7db1211f66f3513706fdf548736aa",
"build_date" : "2020-12-05T01:00:33.671820Z",
"build_snapshot" : false,
"lucene_version" : "8.7.0",
"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}----------------------------------- 安装kibana ----------------------------------------
1.修改/config/kibana.yml
vim /usr/local/kibana-7.10.1-linux-x86_64/config/kibana.yml
server.host: "0.0.0.0"
elasticsearch.hosts: ["http://localhost:9200"]
2.启动kibana(*启动 Kibana 需要先启动 ElasticSearch)
-前台启动
1)切换账户:su myes
2)启动kibana:/usr/local/kibana-7.10.1-linux-x86_64/bin/kibana
-后台启动
1)切换账户:su myes
2)启动kibana:
1)后台启动:nohup /usr/local/kibana-7.15.2/bin/kibana &
2)看日志:tail -f nohup.out
3.访问kibana,进入devtool可以测试elasticsearch,写sql去判断中文插件等是否安装正常
