skywalking 启动报错 this version of the Java skywalking traceid

1、下载安装：

1.1 下载 Skywalking

下载地址： Downloads | Apache SkyWalking

分别下载 apm 和 agent

wegt 下载连接如下；

wget https://archive.apache.org/dist/skywalking/java-agent/8.8.0/apache-skywalking-java-agent-8.8.0.tgz

wget https://archive.apache.org/dist/skywalking/8.8.1/apache-skywalking-apm-8.8.1.tar.gz

1.2 下载 Elasticsearch

wegt https://www.elastic.co/cn/downloads/past-releases/elasticsearch-7-17-0

1.3 Elasticsearch config

在打开安装目录的config下elasticsearch.yml 并添加以下配置

#http.port: 9200
cluster.name: CollectorDBCluster
path.data: /opt/elasticsearch-7.17.0/data
path.logs: /opt/elasticsearch-7.17.0/logs
network.host: 0.0.0.0
http.port: 9200

node.name: node-1
cluster.initial_master_nodes: ["node-1"]

1.4 启动Elasticsearch

# /opt/elasticsearch-7.17.0/bin/elasticsearch

1.5 Sekywalking config

storage:
  selector: ${SW_STORAGE:elasticsearch}
  elasticsearch:
    namespace: ${SW_NAMESPACE:"CollectorDBCluster"}

    indexReplicasNumber: ${SW_STORAGE_ES_INDEX_REPLICAS_NUMBER:1} # Replicas number of new indexes

    superDatasetDayStep: ${SW_SUPERDATASET_STORAGE_DAY_STEP:-1} # Represent the number of days in the super size dataset record index, the default value is the same as dayStep when the value is less than 0
    superDatasetIndexShardsFactor: ${SW_STORAGE_ES_SUPER_DATASET_INDEX_SHARDS_FACTOR:5} #  This factor provides more shards for the super data set, shards number = indexShardsNumber * superDatasetIndexShardsFactor. Also, this factor effects Zipkin and Jaeger traces.
    superDatasetIndexReplicasNumber: ${SW_STORAGE_ES_SUPER_DATASET_INDEX_REPLICAS_NUMBER:0} # Represent the replicas number in the super size dataset record index, the default value is 0.

    oapLogAnalyzer: ${SW_STORAGE_ES_OAP_LOG_ANALYZER:"{\"analyzer\":{\"oap_log_analyzer\":{\"type\":\"standard\"}}}"} # the oap log analyzer. It could be customized by the ES analyzer configuration to support more language log formats, such as Chinese log, Japanese log and etc.
    advanced: ${SW_STORAGE_ES_ADVANCED:""}

主要需要修改

storage:
selector: ${SW_STORAGE:elasticsearch}

我的版本是8.8 如果你是低版本 且Elasticsearch7 ，就配置

storage:
selector: ${SW_STORAGE:elasticsearch7}

然后修改elasticsarch的服务ip和端口就可以了

1.6 启动skywalking

# /opt/apache-skywalking-apm-bin/bin/startup.sh

1.7 docker-compost 部署微服务项目并通过 -javaagent方式

每个jar单独一个文件夹

分别 orderservice、gatway、userservice

version: "3.2"

services:
#  nacos:
#    image: nacos/nacos-server
#    environment:
#      MODE: standalone
#    ports:
#      - "9010:8848"
  userservice:
    env_file: .env
    environment:
      - USER_NAME=${COMNAME}
    build: ./user-service
  
  orderservice:
    build: ./order-service
  gateway:
    build: ./gateway
    ports:
      - "9013:9013"

.env 可以指定运行参数

## docker-compose环境变量

## 测试docker绑定参数
COMNAME=abcdefg129001

每个服务文件夹里面包含以下几个文件

其中dockerfile 如下；

# 将下面的代码放入Dockerfile文件中，复制三份分别放入三个文件夹
FROM java:8
COPY ./app.jar /tmp/app.jar
COPY ./agent /tmp/agent
ENTRYPOINT java  -javaagent:/tmp/agent/skywalking-agent.jar -Dskywalking.agent.service_name=gatway  -Dskywalking.collector.backend_service=sky服务器ip:11800 -jar /tmp/app.jar

其他几个服务相同配置

1.8 skywalking 日志功能

每个springboot小项目单独添加依赖：

<!--打印skywalking的TraceId到日志-->
    <dependency>
        <groupId>org.apache.skywalking</groupId>
        <artifactId>apm-toolkit-logback-1.x</artifactId>
        <version>8.8.0</version>
    </dependency>
    <dependency>
        <groupId>org.apache.skywalking</groupId>
        <artifactId>apm-toolkit-trace</artifactId>
        <version>8.8.0</version>
    </dependency>

其中版本号要与skywalking一致

日志可以使用logback （其他日志框架可以自行google）

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

    <!-- logback-spring加载早于application.yml，如果直接通过${参数key}的形式是无法获取到对应的参数值-->
    <!-- source指定的是application.yml配置文件中key，其它地方直接用${log.path}引用这个值 -->
    <!-- 解决在相对路径下生成log.path_IS_UNDEFINED的问题，增加defaultValue -->
    <springProperty scope="context" name="base.path" source="logging.file.path" defaultValue="${user.home}/kenlogs"/>

    <!-- app.name根据你的应用名称修改 -->
    <springProperty scope="context" name="app.name" source="spring.application.name" defaultValue="applog"/>

    <property name="log.path" value="${base.path}/${app.name}"/>

    <!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度,%msg：日志消息，%n是换行符-->
    <property name="log.pattern" value="%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - [%tid] - %msg%n"/>

    <!-- 控制台日志输出配置 -->
    <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">

            </layout>
        </encoder>
    </appender>


    <appender name="SKYWALKING" class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.log.GRPCLogClientAppender">

    </appender>

            <FileNamePattern>${log.path}-%d{yyyy-MM-dd}.%i.log</FileNamePattern>
            <!-- 日志保留天数 -->
            <MaxHistory>30</MaxHistory>

            </layout>
        </encoder>
    </appender>

    <!-- mybatis日志配置 -->
    <!--    <logger name="java.sql.Connection" level="DEBUG"/>-->
    <!--    <logger name="java.sql.Statement" level="DEBUG"/>-->
    <!--    <logger name="java.sql.PreparedStatement" level="DEBUG"/>-->

    <root level="INFO">
        <appender-ref ref="SKYWALKING"/>
        <appender-ref ref="file"/>
    </root>

    <!-- 配置开发环境，多个使用逗号隔开(例如：dev,sit) -->
<!--    <springProfile name="dev">
        <!–定义日志输出级别–>
        <root level="INFO">
            <appender-ref ref="stdout"/>
            <appender-ref ref="file"/>
        </root>
    </springProfile>

            <appender-ref ref="file"/>
        </root>
    </springProfile>-->

</configuration>

其中最重要的是

appender name=“SKYWALKING” class 指定正确

同时要日志生效；必须修改服务 -javaagent的config/agent.config ； 我开始就是没指定这个；日志一直没生成

plugin.toolkit.log.grpc.reporter.server_host=${SW_GRPC_LOG_SERVER_HOST:skywalking服务ip}
plugin.toolkit.log.grpc.reporter.server_port=${SW_GRPC_LOG_SERVER_PORT:11800}
plugin.toolkit.log.grpc.reporter.max_message_size=${SW_GRPC_LOG_MAX_MESSAGE_SIZE:10485760}
plugin.toolkit.log.grpc.reporter.upstream_timeout=${SW_GRPC_LOG_GRPC_UPSTREAM_TIMEOUT:30}
plugin.toolkit.log.transmit_formatted=${SW_PLUGIN_TOOLKIT_LOG_TRANSMIT_FORMATTED:true}

测试使用日志

简单点直接controller使用一个；真实业务应该在service层比较合适

private final Logger log = LoggerFactory.getLogger(*controller.class);

1.9 最终效果

代码里面获取日志的tranceid

String traceId = TraceContext.traceId();

1.10 日志如何删除历史数据

以上配置保留一天；其他详细需求可以自行百度。
