可以做兼职的网站百度推广好不好做

因为上一篇没对微服务代码很详细地说明，所以在此借花献佛，使用开源的微服务代码去说明如何去做链路追踪。

项目是开源项目，fork到github以及gitee中，然后拉取到本地
后端代码：
https://gitee.com/jelex/mall-swarm.git dev分支
前端管理系统后台代码：
https://gitee.com/jelex/mall-admin-web.git dev分支

呃，因为涉及到部分不宜公开的配置内容，大家有兴趣的可自行网上搜索 mall-swarm项目…

启动后端项目之前准备事项：

• 运行本机docker
  启动my-nacos容器
  启动ES01容器(此容器不用，转而使用服务器上的 es)
  启动kibana-tencent容器（本地mac 上的docker kibana，连接服务器上的es作为存储）
• 运行本机mysql
• 运行 redis
• 运行服务器 es服务
• 运行本机logstash服务
  见 本机mac安装logstash 篇
  logstash配置如下：
  

input {tcp {mode => "server"host => "0.0.0.0"port => 4560codec => json_linestype => "debug"}tcp {mode => "server"host => "0.0.0.0"port => 4561codec => json_linestype => "error"}tcp {mode => "server"host => "0.0.0.0"port => 4562codec => json_linestype => "business"}tcp {mode => "server"host => "0.0.0.0"port => 4563codec => json_linestype => "record"}
}
filter{if [type] == "record" {mutate {remove_field => "port"remove_field => "host"remove_field => "@version"}json {source => "message"remove_field => ["message"]}}
}
output {elasticsearch {hosts => "101.43.xxx.xx:80"index => "mall-%{type}-%{+YYYY.MM.dd}"user => "logstash_writer"password => "logstash_writer"}
}

运行logstash:

cd Documents/work/logstash-7.17.0/bin
jelex@jelexxudeMacBook-Pro bin % ./logstash -f ../config/logstash-mall-swarm.conf &[1] 29577

运行后端服务：

启动前端项目：管理后台：

先设置node版本：

jelex@jelexxudeMacBook-Pro ~ % nvm current
v12.14.0
jelex@jelexxudeMacBook-Pro ~ % node -v
v12.14.0npm install
。。。

运行：

jelex@jelexxudeMacBook-Pro mall-admin-web % nvm use 12         
Now using node v12.14.0 (npm v6.13.4)
jelex@jelexxudeMacBook-Pro mall-admin-web % npm run dev

访问测试：随便点几个功能

查看后端控制台日志：

查看响应头：

查看kibana:
