环境

  • SkyWalking 5.0.0-beat2
  • Mac OS
  • ElasticSearch 5.6.10

安装 ElasticSearch

  • 下载解压 ElasticSearch 5.6.10
curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.10.tar.gz
tar -vxf elasticsearch-5.6.10.tar.gz
  • 修改配置文件config/elasticsearch.yml
cluster.name: CollectorDBCluster
node.name: CollectorDBCluster1
network.host: 10.0.0.34

需要注意的是cluster.name最好是CollectorDBCluster，network.host最好是局域网 IP，否则可能会在使用时出现很多问题

  • 启动
./bin/elasticsearch

安装 SkyWalking

  • 下载解压 SkyWalking 5.0.0-beat2
curl -L -O https://mirrors.tuna.tsinghua.edu.cn/apache/incubator/skywalking/5.0.0-beta/apache-skywalking-apm-incubating-5.0.0-beta.tar.gz

tar -vxf apache-skywalking-apm-incubating-5.0.0-beta.tar.gz
  • 修改配置文件config/application.yml，修改所有的localhost为局域网 IP

  • 修改 webapp/webapp.yml Collector 地址
server:
  port: 8080

collector:
  path: /graphql
  ribbon:
    ReadTimeout: 10000
    listOfServers: 10.0.0.34:10800

security:
  user:
    admin:
      password: admin
  • 修改 config/agent.config Collector 地址
agent.application_code=AppService
collector.servers=10.0.0.34:10800
logging.level=INFO
  • 启动 Collector 和 Webapp
./bin/startup.sh

或单独启动 Collector 和 Webapp

./bin/collectorService.sh

./bin/webappService.sh

使用

  • Jar 启动时添加 VM 参数
-javaagent:/path/to/apache-skywalking-apm-incubating/agent/skywalking-agent.jar -Dskywalking.agent.application_code=YOUR_APP_NAME
  • Tomcat 修改bin/catalina.sh首行配置
# Linux/Mac
CATALINA_OPTS="$CATALINA_OPTS -javaagent:/path/to/skywalking-agent/skywalking-agent.jar"; export CATALINA_OPTS

# Win 
set "CATALINA_OPTS=-javaagent:/path/to/skywalking-agent/skywalking-agent.jar"
