- [3.1 部署ES](#3.1 部署ES)
- [3.2 部署kibana](#3.2 部署kibana)

一、部署nginx

bash 复制代码

docker search nginx #搜索nginx的最新版本

bash 复制代码

docker pull nginx #这里可以指定nginx版本，如果不指定，那么就拉取最新版本latest

bash 复制代码

docker run -d --name nginx01 -p 3344:80 nginx # -d: 运行后台进程，-p: 指定外界访问映射到容器的端口3344-> 80

bash 复制代码

docker exec -it

bash 复制代码

[root@ser878629168738 home]# curl localhost:3344

bash 复制代码

docker ps # 查看正在运行的镜像

bash 复制代码

[root@ser878629168738 home]# docker ps
CONTAINER ID   IMAGE     COMMAND                   CREATED         STATUS         PORTS                                   NAMES
6c890549787f   nginx     "/docker-entrypoint...."   6 minutes ago   Up 6 minutes   0.0.0.0:3344->80/tcp, :::3344->80/tcp   nginx01

bash 复制代码

 docker exec -it nginx01 /bin/bash # 切入到容器中

二、部署Tomcat

bash 复制代码

docker pull tomcat

bash 复制代码

[root@ser878629168738 home]# docker images
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
nginx        latest    605c77e624dd   2 years ago   141MB
tomcat       latest    fb5657adc892   2 years ago   680MB
centos       latest    5d0da3dc9764   2 years ago   231MB

bash 复制代码

 docker run -d -p 3355:8080 --name tomcat01 tomcat #启动tomcat容器，命名为tomcat01

bash 复制代码

[root@ser878629168738 home]# docker ps
CONTAINER ID   IMAGE     COMMAND             CREATED         STATUS         PORTS                                       NAMES
11699886abdc   tomcat    "catalina.sh run"   4 seconds ago   Up 3 seconds   0.0.0.0:3355->8080/tcp, :::3355->8080/tcp   tomcat01

bash 复制代码

docker exec -it 11699886abdc /bin/bash #切入到tomcat01中

三、部署ES+Kibana

3.1 部署ES

bash 复制代码

 docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.6.2 # 这种方式下载的es占用cpu严重，会直接导致操作很卡

bash 复制代码

docker run -d --name elasticsearch02 -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms64m -Xmx512m" elasticsearch:7.6.2   # 这种方式就极大地减少了es占用cpu的比例

bash 复制代码

[root@ser878629168738 home]# docker stats 48ac2b94a32c
CONTAINER ID   NAME              CPU %     MEM USAGE / LIMIT     MEM %     NET I/O     BLOCK I/O        PIDS
48ac2b94a32c   elasticsearch02   0.00%     372.2MiB / 1.794GiB   20.26%    656B / 0B   96.9MB / 810kB   44

bash 复制代码

[root@ser878629168738 home]# curl localhost:9200
{
  "name" : "48ac2b94a32c",
  "cluster_name" : "docker-cluster",
  "cluster_uuid" : "uB1wJTFWSxmNnR7C1BGTtA",
  "version" : {
    "number" : "7.6.2",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "ef48eb35cf30adf4db14086e8aabd07ef6fb113f",
    "build_date" : "2020-03-26T06:34:37.794943Z",
    "build_snapshot" : false,
    "lucene_version" : "8.4.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

3.2 部署kibana

bash 复制代码

docker search kibana

bash 复制代码

docker pull kibana #直接拉取最新kibana版本

bash 复制代码

docker run --name kibana01 -e ELASTICSEARCH_HOSTS=http://xxxxxx:9200 -p 5601:5601 -d kibana # 启动一个新的Docker容器，名为kibana01，运行Kibana服务，并将其配置为连接到运行在http://xxxxx:9200的Elasticsearch实例。容器内的5601端口被映射到宿主机的5601端口，以便用户可以通过浏览器访问Kibana的Web界面。容器将以分离模式在后台运行。

可以通过http://xxxxxx:5601来访问kibana
