Skywalking运维之路(Skywalking服务搭建)

1.前期准备

# 创建文件夹
root@ubuntu2204test99:~# mkdir skywailking
root@ubuntu2204test99:~# cd skywailking/
# 下载oap和ui镜像
root@ubuntu2204test99:~/skywailking# docker pull apache/skywalking-oap-server:10.2.0-java21
root@ubuntu2204test99:~/skywailking# docker pull apache/skywalking-ui:10.2.0-java21# 启动容器
root@ubuntu2204test99:~/skywailking# docker run -d -it --name skywalking-oap apache/skywalking-oap-server:10.2.0-java21
root@ubuntu2204test99:~/skywailking# docker run -d -it --name skywalking-ui apache/skywalking-ui:10.2.0-java21
88e679e568c7e2c0bf53326da4201b4b26410f7456cd3e005194bba322c7258e
# 查看启动容器ID
root@ubuntu2204test99:~/skywailking# docker ps |grep sky

root@ubuntu2204test99:~/skywailking# docker cp 88e679e568c7:/skywalking .
Successfully copied 38.1MB to /root/skywailking/.
root@ubuntu2204test99:~/skywailking# mv skywalking skywalking-ui
root@ubuntu2204test99:~/skywailking# docker cp 2c426d0e6ac4:/skywalking .
Successfully copied 137MB to /root/skywailking/.
root@ubuntu2204test99:~/skywailking# mv skywalking skywalking-oap# 删除临时容器
root@ubuntu2204test99:~/skywailking# docker rm -f 88e679e568c7 2c426d0e6ac4

2. Docker-compose文件编写

version: '3.8'
services:oap:image: apache/skywalking-oap-server:10.2.0-java21container_name: oapports:- "11800:11800"- "12800:12800"- "1234:1234"  #自监控端口healthcheck:test: [ "CMD-SHELL", "/skywalking/bin/swctl ch" ]interval: 30stimeout: 10sretries: 3start_period: 10senvironment:SW_HEALTH_CHECKER: defaultSW_TELEMETRY: prometheusJAVA_OPTS: "-Xms2048m -Xmx2048m"volumes:- ./skywalking-oap:/skywalking #映射配置文件ui:image: apache/skywalking-ui:10.2.0-java21container_name: uidepends_on:oap:condition: service_healthyports:- "9301:8080"volumes:- ./skywalking-ui:/skywalking #映射配置文件

3.修改OAP配置

root@ubuntu2204test99:~# cd skywailking/skywalking-oap
root@ubuntu2204test99:~/skywailking/skywalking-oap# vi config/application.yml
# 要修改的几个关键位置
# 存储设置
storage:selector: ${SW_STORAGE:elasticsearch}  # 使用elasticsearch存储elasticsearch:namespace: ${SW_NAMESPACE:"skywalking"}  # es命名空间clusterNodes: ${SW_STORAGE_ES_CLUSTER_NODES:192.168.1.99:9201,192.168.1.99:9202,192.168.1.99:9203}  #es连接地址.......user: ${SW_ES_USER:"elastic"}  #es账号password: ${SW_ES_PASSWORD:"123456"}  #es密码.........
# 自监控配置
telemetry:selector: ${SW_TELEMETRY:prometheus}none:prometheus:#host: ${SW_TELEMETRY_PROMETHEUS_HOST:0.0.0.0}#port: ${SW_TELEMETRY_PROMETHEUS_PORT:1234}host: 0.0.0.0port: 1234sslEnabled: ${SW_TELEMETRY_PROMETHEUS_SSL_ENABLED:false}sslKeyPath: ${SW_TELEMETRY_PROMETHEUS_SSL_KEY_PATH:""}sslCertChainPath: ${SW_TELEMETRY_PROMETHEUS_SSL_CERT_CHAIN_PATH:""}

4.修改UI配置

serverPort: 8080
oapServices: http://192.168.1.99:12800
zipkinServices: http://192.168.1.99:9412

5.启动Docker-compose

root@ubuntu2204test99:~/skywailking# docker-compose up -d
