开始语

一位普通的程序员,慢慢在努力变强!

1.安装

skywalking官网访问👈

skywalking可以直接监控linux资源嘛 skywalking nginx_linux

1.1 下载文件压缩包

wget https://dlcdn.apache.org/skywalking/9.3.0/apache-skywalking-apm-9.3.0.tar.gz
wget https://dlcdn.apache.org/skywalking/java-agent/8.14.0/apache-skywalking-java-agent-8.14.0.tgz

1.2 解压压缩包

tar -xzvf apache-skywalking-apm-9.3.0.tar.gz  
tar -zxvf apache-skywalking-java-agent-8.14.0.tgz

1.3 修改web-ui启动端口

# 找到webapp目录下的yml文件
vim apache-skywalking-apm-bin/webapp/application.yml
serverPort: ${SW_SERVER_PORT:-8686}  # 修改这行,默认是8080

1.4 修改存储:我这里使用的是mysql

# 找到config目录下对应的yml文件
vim apache-skywalking-apm-bin/config/application.yml
storage:
  selector: ${SW_STORAGE:mysql} # 默认是h2,将数据进行持久化。重启数据不丢失。 关于存储类选型,设置方式都差不多
mysql:
    properties:
      jdbcUrl: ${SW_JDBC_URL:"jdbc:mysql://localhost:3306/skywalking_data?rewriteBatchedStatements=true"}
      dataSource.user: ${SW_DATA_SOURCE_USER:root}
      dataSource.password: ${SW_DATA_SOURCE_PASSWORD:root@1234} # 配置数据库

温馨提示:由于缺少mysql驱动,自行下载将驱动jar放置此目录下:/apache-skywalking-apm-bin/oap-libs
再去mysql中新增库:skywalking_data # 不然启动会报错!

1.4 执行文件:startup.sh

./startup.sh  
# 出现下面提示说明执行成功:
SkyWalking OAP started successfully!                                                                                                                                       
SkyWalking Web Application started successfully!

1.5 访问展示

浏览器输入:ip:8686

skywalking可以直接监控linux资源嘛 skywalking nginx_kubernetes_02


上面是接入了两个服务!

# 接入方法:  java-ops
-javaagent:/skywalking/skywalking-agent/skywalking-agent.jar # jar包位置
-DSW_AGENT_NAME=dev::demo2 # 前面的代表分组,后面的是项目名称
-DSW_AGENT_COLLECTOR_BACKEND_SERVICES=127.0.0.1:11800 # 数据接入点

# 每个项目需要拷贝一份skywalking-agent.jar

温馨提示:如果您是jenkins-k8s集成,请查看此篇文章:jenkins自动化部署👈

2.SpringBoot集成

温馨提示:此处的接入重点是针对jenkins-k8s的方式进行部署

2.1 本地项目部署

skywalking可以直接监控linux资源嘛 skywalking nginx_java_03

2.2 jenkins项目部署

2.2.1 将skywalking-agent.jar打包成镜像
vim Dockerfile

# (方式一)注意Dockerfile文件放置skywalking-agent根目录
FROM busybox:latest
LABEL maintainer="tianyu"
COPY ./ /usr/skywalking/agent/

# (方式二[推荐])如果你不想将Dockerfile放置容器中,那么你的Dockerfile需要放置skywalking-agent父级目录下
FROM busybox:latest
LABEL maintainer="tianyu"
COPY skywalking-agent/ /usr/skywalking/agent/

# 开始制作镜像,版本最好是和你的jar一致
docker build -t skywalking-agent:8.14.0 .

# (此处是进入了容器内部)因为在容器中接入agent和Dockerfile没有关系,所以不需要将它也复制到容器内部,如下:
root@demo3-75c8d69dfb-ff85z:/usr/skywalking/agent# ls
Dockerfile(这个复制到容器内部中了)  LICENSE  NOTICE  activations  bootstrap-plugins  config  licenses  logs  optional-plugins  optional-reporter-plugins  plugins  skywalking-agent.jar
2.2.2 开始编写Deployment.yaml文件

温馨提示:如果您使用的是jenkins-k8s的方式,则可以忽略次此步骤!
请查看此篇文章:jenkins自动化部署👈

# 编写yml文件

2.3.3 配置yml开关,启动日志,测试结果
#application.yml开启日志追踪
skywalking:
  log:
    enable: true # false是关闭,不配默认关闭
2.3.4 验证是否配置成功

温馨提示:项目自行定义接口,然后通过日志@Slf4j来记录日志!
