skywalking监控微服务
SkyWalking整体架构
SkyWalking环境部署
1下载SkyWalking软件包
http://archive.apache.org/dist/skywalking/6.6.0/
注意:使用es版本的我们需要下载带有es结尾的下载包
2搭建SkyWalkingOAP和SkyWalking UI服务
数据存储我们使用es和mysql两种方式作为数据库存储。
3切换到bin目录。 ./startup.sh ,windows双击即可,skywalking-web-ui的端口配置文件在
web\webapp.yml中。默认为8080
4访问skywalking UI界面,127.0.0.0:7777/
可以在IDEA里面添加参数
-javaagent:D:\gitrepo\skywalking-apm\apache-skywalking-apm-6.6.0\apache-skywalking-apm-bin\agent\skywalking-agent.jar

启动oapServer会在es中添加索引
如果使用mysql作为持久化存储,也是一样,
FAQ
使用mysql存储可能遇到的问题
ModuleStartException: Specified key was too long; max key length is 767 bytes
解决办法
参考:https://github.com/apache/skywalking/issues/5113
drop database if exists k8s_skywalking;
CREATE DATABASE IF NOT EXISTS k8s_skywalking DEFAULT CHARSET latin1 COLLATE latin1_general_ci;
