一、安装elasticsearch
1、拉取镜像
docker pull elasticsearch:6.5.0
2、 启动容器
docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 elasticsearch:6.5.0
3573e7af2aea8767415847b0c1214e3d08d11ce09ecf745eeb501f02d4530624
使用docker ps查看发现容器并没有启动成功，查看日志
docker logs -f 3573

查看max_map_count的值
$ cat /proc/sys/vm/max_map_count
65530
重新设置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直接写到/etc/sysctl.conf中,然后执行sysctl -p
重新启动容器
docker start elasticsearch
浏览器访问
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、安装elasticsearch-head插件
1、拉取镜像
docker pull mobz/elasticsearch-head:5
2、启动容器
docker run -d --name es-head -p 9100:9100 mobz/elasticsearch-head:5
访问 http://ip:9100
image.png
提示未连接，修改elasticsarch-head的监听
进入容器
docker exec -it es-head bash
使用vim会提示vim命令不存在，安装vim命令，若是安装时报错，说yum command not found ,使用apt-get update,然后使用apt-get install vim -y 进行安装下载即可
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作为服务器的，所以他的启动后监听的host默认是localhost， 所以我们要修改其中的配置文件，增加一些配置，这样可以使得能够被外部访问的到，修改Gruntfile.js文件，添加hostname

重启es-head
docker restart es-head

连接elasticsearch的地址，查看控制台会提示跨域错误，修改elasticsearch.yml解决跨域问题，在文件最后添加
http.cors.enabled: true
http.cors.allow-origin: "*"
以挂载的方式启动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的内容
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 解决跨域问题
http.cors.enabled: true
http.cors.allow-origin: "*"
可能会启动失败，出现权限不足的问题，这时候需要关闭selinux
[root@localhost home]# docker logs -f df99

启动之后再次连接就连接成功了

三、安装ik分词器
进入到容器里
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
