第二十二章 Centos7下Docker安装Elasticsearch

一、查找Elasticsearch镜像

[root@staging ~]# docker search elasticsearch

二、拉取Elasticsearch镜像

[root@staging ~]# docker pull elasticsearch:7.14.2

三、编写配置文件

[root@staging ~]# mkdir -p /data2/elasticsearch/config
[root@staging config]# vim elasticsearch.yml 
cluster.name: "docker-cluster"
network.host: 0.0.0.0
http.cors.enabled: true
http.cors.allow-origin: "*"
[root@staging config]# chmod  -R 777 /data2/elasticsearch/

四、运行Elasticsearch

[root@staging ~]# docker run \
 -itd  \
 -p 9200:9200 \
 -p 9300:9300 \
 -v /data2/elasticsearch/data:/usr/share/elasticsearch/data \
 -v /data2/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
 -v /data2/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
 -v /usr/share/zoneinfo/Asia/Shanghai:/etc/localtime \
 -e discovery.type=single-node \
 -e ES_JAVA_OPTS="-Xms64m -Xmx512m" \
 --restart always \
 --privileged=true \
 --name es \
 elasticsearch:7.14.2

五、验证Elasticsearch容器

[root@staging config]# docker ps
CONTAINER ID   IMAGE                  COMMAND                  CREATED         STATUS                PORTS                                                                                                                   NAMES
7e1f75c1dd67   elasticsearch:7.14.2   "/bin/tini -- /usr/l…"   7 seconds ago   Up 3 seconds          0.0.0.0:9200->9200/tcp, :::9200->9200/tcp, 0.0.0.0:9300->9300/tcp, :::9300->9300/tcp                                    es

六、浏览器测试访问

输入IP+Port，本机192.168.2.18:9200，输入正确的用户名和修改过后的密码即可正常登陆。

七、安装head插件

#1.拉取镜像
[root@staging ~]# docker pull mobz/elasticsearch-head:5

#2.启动es-head容器
[root@staging ~]# docker run \
-itd \
-p 9100:9100 \
-v /usr/share/zoneinfo/Asia/Shanghai:/etc/localtime \
--restart always \
--privileged=true \
--name es_head  
mobz/elasticsearch-head:5

八、浏览器访问

浏览器访问ip:9100，连接es填入http://192.168.2.18:9200点击连接看到状态为绿色表示正常。
