Apache SkyWalking 监控 Linux 实战_skywalking监控服务器内存、cpu使用情况(1)
16、mysql的innodb如何定位锁问题,mysql如何减少主从复制延迟?2、在工作中,运维人员经常需要跟运营人员打交道,请问运营人员是做什么工作的?6、Squid、Varinsh和Nginx有什么区别,工作中你怎么选择?5、LVS、Nginx、HAproxy有什么区别?9、讲述一下Tomcat8005、8009、8080三个端口的含义?7、Tomcat和Resin有什么区别,工作中你怎么选择
先自我介绍一下,小编浙江大学毕业,去过华为、字节跳动等大厂,目前阿里P7
深知大多数程序员,想要提升技能,往往是自己摸索成长,但自己不成体系的自学效果低效又漫长,而且极易碰到天花板技术停滞不前!
因此收集整理了一份《2024年最新Linux运维全套学习资料》,初衷也很简单,就是希望能够帮助到想自学提升又不知道该从何学起的朋友。
既有适合小白学习的零基础资料,也有适合3年以上经验的小伙伴深入学习提升的进阶课程,涵盖了95%以上运维知识点,真正体系化!
由于文件比较多,这里只是将部分目录截图出来,全套包含大厂面经、学习笔记、源码讲义、实战项目、大纲路线、讲解视频,并且后续会持续更新
如果你需要这些资料,可以添加V获取:vip1024b (备注运维)

SW_ZIPKIN_ADDRESS: http://oap:9412
###### .env
用于镜像版本,这里使用 SkyWalking 9.7.0 版本,也是当前最新的版本
The docker-compose.yml file is meant to be used locally for testing only after a local build, if you want to use it
with officially released Docker images, please modify the environment variables on your command line interface.
i.e.:
export OAP_IMAGE=apache/skywalking-oap-server:
export UI_IMAGE=apache/skywalking-ui:
docker compose up
ES_VERSION=7.4.2
OAP_IMAGE=apache/skywalking-oap-server:9.7.0
UI_IMAGE=apache/skywalking-ui:9.7.0
启动 SkyWalking
docker compose up
启动完成后,访问 <http://IP:8080> 就可以正常打开 dashboard 页面了,当然这个时候还看不到监控数据。
##### 部署 Prometheus node-exporter
[node-exporter 官方文档]( ) ,下载地址 <https://prometheus.io/download/#node_exporter>
这里下载 1.7.0 版本
wget https://github.com/prometheus/node_exporter/releases/download/v1.7.0/node_exporter-1.7.0.linux-amd64.tar.gz
tar xvfz node_exporter-1.7.0.linux-amd64.tar.gz
cd node_exporter-1.7.0.linux-amd64
./node_exporter
启动成功后访问 <http://IP:9100/metrics> 可以看到采集到的 metrics 信息。

##### 部署 OpenTelemetry Collector
[OpenTelemetry Collector 官方文档]( )
这里将 `otel-collector` 和 skywalking 一起通过 docker compose 部署,完整配置如下:
