微服务spring-cloud 链路追踪skywalking6.x引入

1、准备工做

环境：

1.jdk1.8，高于不支持

2.elasticsearch6.5.4搜索引擎：

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.5.4.tar.gz

解压：tar -zxvf elasticsearch-6.5.4.tar.gz

配置：

vim elasticsearch-6.5.4/config/elasticsearch.yml

修改如下内容

cluster.name: myskywalking

path.data: /opt/data/es/data

path.logs: /opt/data/es/logs

bootstrap.memory_lock: false

bootstrap.system_call_filter: false

network.host: 127.0.0.1    #推荐本机IP，

http.port: 9200

启动es

2、安装skywalking服务端

1.官网下载：http://skywalking.apache.org/

#wget http://mirror.bit.edu.cn/apache/skywalking/6.1.0/apache-skywalking-apm-6.1.0.tar.gz 

#解压：tar -zxvf apache-skywalking-apm-6.1.0.tar.gz 

2.修改webapp端口由默认8080，改为13800：

cd /home/wshop/skywalking/apache-skywalking-apm-bin/webapp

vi webapp.yml

server:
  port: 13800

3.修改es配置

cd /home/wshop/skywalking/apache-skywalking-apm-bin/config

vi application.yml

4.启动

cd /home/wshop/skywalking/apache-skywalking-apm-bin/bin

./startup.sh

将启动两个服务：收集器11800端口和监控ui界面13800端口

访问：http://192.168.60.235:13800/

说明服务端已经启动成功；

3、客户端引入：

192.168.60.235:11800属于收集器

本地服务器，只要对应上"skywalking-agent.jar"

其余服务只要将agent目录复制过去，而后启动对应该服务接口，即能进行监控；

相应jar工程，在启动脚本前增长“ -javaagent:/home/wshop/skywalking/apache-skywalking-apm-bin/agent/skywalking-agent.jar -Dskywalking.agent.service_name=${APPNAME} -Dskywalking.collector.backend_service=192.168.60.235:11800”  便可。

完整客户端run脚本
