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
08c01a0ec47e: Pull complete
5ff2ab324559: Pull complete

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.

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]#

【有问题描述】
一、创建Dockerfile文件
[root@boco201 skywalking]# pwd
/opt/skywalking
[root@boco201 skywalking]# more Dockerfile
#标题使用官方的OpenJDK 8镜像作为基础镜像
FROM openjdk:8-jre-alpine
#设置环境变量
ENV SW_OAP_VERSION=8.1.0
#创建工作目录
WORKDIR /opt/skywalking
#下载并解压SkyWalking OAP Server
RUN wget &&
tar -xzf apache-skywalking-apm-KaTeX parse error: Expected 'EOF', got '&' at position 25: …ERSION}.tar.gz &̲& \ rm apac…{SW_OAP_VERSION}.tar.gz
#将OAP Server的配置文件复制到容器中
COPY config/application.yml apache-skywalking-apm-KaTeX parse error: Expected 'EOF', got '#' at position 41: …pplication.yml #̲暴露OAP Server的端口…{SW_OAP_VERSION}/bin/oap.sh", “start”]
二、创建SkyWalking OAP Server配置文件
[root@boco201 skywalking]# pwd
/opt/skywalking
[root@boco201 skywalking]# more application.yml
management:
metrics:
export:
skywalking:
enabled: true
endpoint:
health:
show-details: always
skywalking:
oap:
cluster:
enabled: false
receiver-trace:
segment-max-send-size: 30000
buffer-size: 10000
grpc:
oap:
host: 192.168.100.201
port: 11800
lte:
host: 192.168.100.201
port: 12800
三、构建Docker镜像
#docker build -t skywalking-oap .
