Docker安装Elasticsearch和Kibana
Docker安装请参考：https://www.jianshu.com/p/64de448b637c
1、安装Elasticsearch和Kibana
1.1、安装Elasticsearch
docker pull elasticsearch:7.10.1
1.2、安装kibana，kibana的版本一定要和elasticsearch的版本一样。
docker pull kibana:7.10.1
1.3、创建Elasticsearch文件夹，以后会把配置文件放到config下，数据文件放到data下
mkdir -p /usr/local/app/elasticsearch/config
mkdir -p /usr/local/app/elasticsearch/data
1.4、进入config文件夹，创建Elasticsearch配置文件
cd /usr/local/app/elasticsearch/config/
vi elasticsearch.yml
elasticsearch.yml中添加“http.host: 0.0.0.0”，配置Elasticsearch可被任意主机连接
[root@localhost config]# cat elasticsearch.yml
http.host: 0.0.0.0
[root@localhost config]#
2、启动Elasticsearch
启动命令：
--name 为容器起名字；
-p 9200:9200 监听9200端口，接收http请求；
-p 9300:9300 监听9300端口，集群间通信端口；
-e "discovery.type=single-node" 以单节点运行；
-e ES_JAVA_OPTS="-Xms64m -Xmx512m" 指定初始占用内存64m，最大占用512m；
-v /usr/local/app/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml 将容器中的配置文件挂载到，刚才创建的config/elasticsearch.yml文件中；
-v /usr/local/app/elasticsearch/data:/usr/share/elasticsearch/data 挂载data目录；
-v /usr/local/app/elasticsearch/plugins:/usr/share/elasticsearch/plugins 挂载插件目录plugins；
-d elasticsearch:7.10.1 使用刚才下载的镜像 ；
[root@localhost config]# docker run --name elasticsearch -p 9200:9200 -p 9300:9300 \
> -e "discovery.type=single-node" \
> -e ES_JAVA_OPTS="-Xms64m -Xmx512m" \
> -v /usr/local/app/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
> -v /usr/local/app/elasticsearch/data:/usr/share/elasticsearch/data \
> -v /usr/local/app/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
> -d elasticsearch:7.10.1

[root@localhost config]# docker ps

[root@localhost config]#
过一会，elasticsearch会错误退出，查看docker中elasticsearch日志，出现访问拒绝报错：
[root@localhost config]# docker logs elasticsearch

修改elasticsearch文件夹权限，-R递归修改所有子文件权限，777所有用户、分组均可读可写
[root@localhost elasticsearch]# chmod -R 777 /usr/local/app/elasticsearch
[root@localhost elasticsearch]# ll
total 0
drwxrwxrwx. 2 root root 31 Jan 13 16:00 config
drwxrwxrwx. 2 root root 6 Jan 13 15:55 data
drwxrwxrwx. 2 root root 6 Jan 13 16:14 plugins
查看elasticsearch容器，并重启elasticsearch，docker start后面跟上自己elasticsearch容器id就可以了。
[root@localhost elasticsearch]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e4fba7b5ba08 elasticsearch:7.10.1 "/tini -- /usr/local…" 23 hours ago Exited (1) 23 hours ago elasticsearch
[root@localhost elasticsearch]# docker start e4fba7b5ba08
e4fba7b5ba08
容器启动成功
[root@localhost elasticsearch]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

此时访问虚拟机9200端口，返回成功

3、启动kibana
--name kibana：给容器起名字kibana；
-e ELASTICSEARCH_HOSTS=http://{自己的虚拟机地址}:9200：指定elasticsearch的地址和端口；
-p 5601:5601：kibana的操作端口；
-d kibana:7.10.1：kibana的版本；
[root@localhost elasticsearch]# docker run --name kibana -e ELASTICSEARCH_HOSTS=http://192.168.43.129:9200 -p 5601:5601 -d kibana:7.10.1
