CentOS部署Skywalking

一、安装Docker

#yum -y install gcc

#yum -y install gcc-c++

#yum install -y yum-utils

设置国内的镜像仓库

#yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

更新yum软件包索引

#yum makecache fast

安装Docker引擎

#yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

启动Docker引擎

#systemctl start docker

设置开机启动

#systemctl enable docker.service

关闭开机启动

#systemctl disable docker.service

二、下载Elasticsearch容器

#docker pull elasticsearch:8.1.0

8.1.0: Pulling from library/elasticsearch

三、启动Elasticsearch容器

#docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:8.1.0

指定外挂目录

#docker run -itd --name=elasticsearch --restart=always -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -v /opt/data/elasticsearch8/data:/usr/share/elasticsearch/data -v /opt/data/elasticsearch8/logs:/usr/share/elasticsearch/logs elasticsearch:8.1.0

访问：https://192.168.100.201:9200/，用户名：elastic，口令：

四、修改Elasticsearch密码

#docker exec -it elasticsearch /bin/bash

elasticsearch@4bf62698795e:~$ ./bin/elasticsearch-setup-passwords interactive

Note: The 'elasticsearch-setup-passwords' tool has been deprecated. This command will be removed in a future release.

Initiating the setup of passwords for reserved users elastic,apm_system,kibana,kibana_system,logstash_system,beats_system,remote_monitoring_user.

You will be prompted to enter passwords as the process progresses.

Please confirm that you would like to continue $y/N$ y

Enter password for $beats_system$ :

Reenter password for $beats_system$ :

Enter password for $remote_monitoring_user$ :

Reenter password for $remote_monitoring_user$ :

Changed password for user $apm_system$

Changed password for user $kibana_system$

Changed password for user $kibana$

Changed password for user $logstash_system$

Changed password for user $beats_system$

Changed password for user $remote_monitoring_user$

Changed password for user $elastic$

五、部署kibana容器（非必须）

1）下载容器

#docker pull elastic/kibana:8.1.0

8.1.0: Pulling from elastic/kibana

4fb807caa40a: Pull complete

2e80e64cf6e3: Pull complete

Status: Downloaded newer image for elastic/kibana:8.1.0

docker.io/elastic/kibana:8.1.0

2）启动容器

#docker run -d --name kibana002 --link elasticsearch -e ELASTICSEARCH_URL=https://192.168.100.201:9200/ -p 5601:5601 elastic/kibana:8.1.0

532df9b9966754e88e25d9a02d407f6014550f7df7c938fbdd44554447890bc5

3）停止容器

#docker stop 0be2e886baaa

#docker kill 0be2e886baaa

4）访问

http://192.168.100.201:5601/

5）验证

#docker exec -it elasticsearch /bin/bash

elasticsearch@4bf62698795e:~$ cd bin

elasticsearch@4bf62698795e:~/bin$ elasticsearch-create-enrollment-token --scope kibana

WARNING: Owner of file $/usr/share/elasticsearch/config/users$ used to be $root$ , but now is $elasticsearch$

WARNING: Owner of file $/usr/share/elasticsearch/config/users_roles$ used to be $root$ , but now is $elasticsearch$

6）验证

#docker exec -it kibana002 /bin/bash

kibana@532df9b99667:~$ cd bin

kibana@532df9b99667:~/bin$ kibana-verification-code

Your verification code is: 894 715

7）登录，同Elasticsearch的密码（elastic）

六、部署Skywalking镜像

#docker pull apache/skywalking-oap-server:8.9.1

#docker pull apache/skywalking-ui:8.9.1

如果pull操作一直有waiting：

$root@boco201 docker$ # pwd

/etc/docker

$root@boco201 docker$ # more daemon.json

{

"registry-mirrors":[

"https://9cpn8tt6.mirror.aliyuncs.com",

"https://registry.docker-cn.com"

]

}

$root@boco201 docker$ #

七、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 elasticsearch:elasticsearch -e SW_STORAGE=elasticsearch -e SW_STORAGE_ES_CLUSTER_NODES=elasticsearch:9200 apache/skywalking-oap-server:8.9.1

八、登录容器Skywalking-oap

#docker exec -it skywalking-oap bash

九、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:8.9.1

十、访问Skywalking-ui

http://192.168.100.201:8080/

十一、Java服务接入Skywalking

1）下载agent，从https://archive.apache.org/dist/skywalking/8.9.1/ 或 https://skywalking.apache.org/downloads/ 解压获得agent.jar（或agent-analyzer-8.9.1.jar）

2）jar包执行方式

#java -javaagent:/opt/data/skywalking-agent/agent/skywalking-agent.jar -Dskywalking.agent.service_name=my-app-service -Dskywalking.collector.backend_service=192.168.100.201:11800 -jar my-app-service.jar &

#java -javaagent:/opt/data/skywalking-agent/agent/agent-analyzer-8.9.1.jar -Dskywalking.agent.service_name=my-app-service -Dskywalking.collector.backend_service=192.168.100.201:11800 -jar my-app-service.jar &
