目录
2.1.2 持久化启动elasticsearch，安装elasticsearch并挂载文件
操作系统:CentOS7.4
一、镜像准备
1.1 搭建skywalking需要用到三个镜像
elasticsearch：用来存储数据
skywalking-oap-server：Skywalking服务器
skywalking-ui ：Skywalking的UI界面
1.2 下载镜像
docker pull elasticsearch:7.9.0
docker pull apache/skywalking-oap-server:8.9.1
docker pull apache/skywalking-ui:8.9.1
1.3 查看镜像
docker images
二、方式一：单独镜像安装
2.1 安装elasticsearch
2.1.1 本机创建持久化目录，官方推荐
注意：创建目录的权限要满足需求
mkdir -p /data/elasticsearch7/data
mkdir -p /data/elasticsearch7/logs
2.1.2 持久化启动elasticsearch，安装elasticsearch并挂载文件
docker run -itd \
--name=es7 \
--restart=always \
-p 9200:9200 -p 9300:9300 \
-e "discovery.type=single-node" \
-v /data/elasticsearch7/data:/usr/share/elasticsearch/data \
-v /data/elasticsearch7/logs:/usr/share/elasticsearch/logs \
elasticsearch:7.9.0
2.1.3 查看启动情况
docker ps -aShell
Copy
2.1.4 查看镜像日志
docker logs -f es7Shell
Copy
2.1.5 验证ES
浏览器访问：http://192.168.3.176:9200/，返回：

cluster_name: "docker-cluster",
cluster_uuid: "k06cLZkBSjiO6aYVKBtfYQ",
version: {
number: "7.9.0",
build_flavor: "default",
build_type: "docker",
build_hash: "a479a2a7fce0389512d6a9361301708b92dff667",
build_date: "2020-08-11T21:36:48.204330Z",
build_snapshot: false,
lucene_version: "8.6.0",
minimum_wire_compatibility_version: "6.8.0",
minimum_index_compatibility_version: "6.0.0-beta1"
},
tagline: "You Know, for Search"
}
2.2 安装skywalking-oap
注意：需要先安装好es才能安装oap
2.2.1 持久化启动 skywalking-oap
docker run -itd \
--name skywalking-oap \
--restart=always \
-e TZ=Asia/Shanghai \
-p 12800:12800 \
-p 11800:11800 \
--link es7:es7 \
-e SW_STORAGE=elasticsearch \
-e SW_STORAGE_ES_CLUSTER_NODES=es7:9200 \
apache/skywalking-oap-server:8.9.1
-e TZ=Asia/Shanghai：指定时区。
--link es7:es7：关联es7容器，通过容器名字来解决ip会发生变更的问题。
-e SW_STORAGE=elasticsearch：设置环境变量，指定存储方式。
-e SW_STORAGE_ES_CLUSTER_NODES=es7:9200：设置环境变量，指定ES的地址
2.2.2 登录容器
docker exec -it skywalking-oap bashShell
Copy
2.3 安装skywalking-ui
2.3.1 持久化启动 skywalking-ui
docker run -itd --name skywalking-ui \
--restart=always \
-e TZ=Asia/Shanghai \
-p 8080:8080 \
--link skywalking-oap:skywalking-oap \
-e SW_OAP_ADDRESS=skywalking-oap:12800 \
apache/skywalking-ui:8.9.1Shell
Copy
2.4 浏览器验证
访问UI：http://192.168.3.176:8080/
三、方式二：docker-compose 安装
3.1 编写docker-compose.yml文件
skywalking/docker at master · apache/skywalking · GitHub
官网有示例docker-compose.yml文件，我们只需要下载下来修改下即可。

docker-compose up -dShell
Copy
3.3 查看启动镜像
docker-compose psShell
Copy
3.4 浏览器验证
访问网址 http://192.168.3.176:8080/
四、java服务接入skywalking
4.1 下载agent
下载源码包，然后解压取agent目录 Index of /dist/skywalking/8.9.1 或 Downloads | Apache SkyWalking 解压获得agent.jar。
4.2 jar包方式(推荐)
java -javaagent:/data/skywalking-agent/agent/skywalking-agent.jar
-Dskywalking.agent.service_name=my-app-service
-Dskywalking.collector.backend_service=192.168.3.176:11800
-jar my-app-service.jar &
