一信认、安裝elasticsearch

1其掂、拉取鏡像

docker pull elasticsearch:6.5.0

2喘漏、 啟動(dòng)容器

docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 elasticsearch:6.5.0
3573e7af2aea8767415847b0c1214e3d08d11ce09ecf745eeb501f02d4530624

使用docker ps查看發(fā)現(xiàn)容器并沒(méi)有啟動(dòng)成功盔夜，查看日志

docker logs -f 3573

查看max_map_count的值

$ cat /proc/sys/vm/max_map_count
65530

重新設(shè)置max_map_count的值

$ sysctl -w vm.max_map_count=262144
vm.max_map_count = 262144

永久更改max_map_count值，
vm.max_map_count=200000直接寫到/etc/sysctl.conf中,然后執(zhí)行sysctl -p
重新啟動(dòng)容器

docker start  elasticsearch

瀏覽器訪問(wèn)

http://ip:9200
{
  "name" : "IK4_5lR",
  "cluster_name" : "docker-cluster",
  "cluster_uuid" : "xw5vUFlqSu2G6lPOSq_8AQ",
  "version" : {
    "number" : "6.5.0",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "816e6f6",
    "build_date" : "2018-11-09T18:58:36.352602Z",
    "build_snapshot" : false,
    "lucene_version" : "7.5.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

二本慕、安裝elasticsearch-head插件

1、拉取鏡像

docker pull mobz/elasticsearch-head:5

2牛欢、啟動(dòng)容器

docker run -d --name es-head -p 9100:9100 mobz/elasticsearch-head:5

訪問(wèn) http://ip:9100

image.png

docker exec -it es-head bash

使用vim會(huì)提示vim命令不存在，安裝vim命令，若是安裝時(shí)報(bào)錯(cuò)记靡，說(shuō)yum command not found ,使用apt-get update,然后使用apt-get install vim -y 進(jìn)行安裝下載即可

root@616029884dd4:/usr/src/app# vim Gruntfile.js 
bash: vim: command not found
root@616029884dd4:/usr/src/app# yum install -y vim
bash: yum: command not found
root@616029884dd4:/usr/src/app# apt-get update

es-head使用的grunt-server作為服務(wù)器的，所以他的啟動(dòng)后監(jiān)聽的host默認(rèn)是localhost啼止， 所以我們要修改其中的配置文件趣些，增加一些配置，這樣可以使得能夠被外部訪問(wèn)的到舔庶，修改Gruntfile.js文件朦促，添加hostname

重啟es-head

docker restart es-head

連接elasticsearch的地址油湖，查看控制臺(tái)會(huì)提示跨域錯(cuò)誤，修改elasticsearch.yml解決跨域問(wèn)題领跛，在文件最后添加

http.cors.enabled: true
http.cors.allow-origin: "*" 

以掛載的方式啟動(dòng)es

docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -v /home/elasticsearch/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml elasticsearch:6.5.0

elasticsearch.yml的內(nèi)容

cluster.name: "docker-cluster"
network.host: 0.0.0.0

# minimum_master_nodes need to be explicitly set when bound on a public IP
# # set to 1 to allow single node clusters
# # Details: https://github.com/elastic/elasticsearch/pull/17288
discovery.zen.minimum_master_nodes: 1

# head setting  解決跨域問(wèn)題
http.cors.enabled: true
http.cors.allow-origin: "*" 

可能會(huì)啟動(dòng)失敗乏德，出現(xiàn)權(quán)限不足的問(wèn)題，這時(shí)候需要關(guān)閉selinux

啟動(dòng)之后再次連接就連接成功了

三吠昭、安裝ik分詞器

進(jìn)入到容器里

docker exec -it elasticsearch bash
cd bin
[root@d6bd6a5487ae bin]# elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.5.0/elasticsearch-analysis-ik-6.5.0.zip
