服务追踪工具 SkyWarking 安装与部署，并整合微服务，集群环境。
SkyWalking 是用于对微服务，Cloud Native，容器等提供应用性能监控和分布式调用链追踪的工具
环境
- ElasticSearch 5.6.10
- SkyWalking 5.0.0-GA
- centos7
- jdk1.8
ElasticSearch安装
- 下载解压 ElasticSearch 5.6.10
curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.10.tar.gz
tar -vxf elasticsearch-5.6.10.tar.gz
mv elasticsearch-5.6.10 elasticsearch
- 修改配置文件 elasticsearch/config/elasticsearch.yml
cluster.name: CollectorDBCluster
node.name: CollectorDBCluster1
network.host: 172.16.255.148
需要注意的是cluster.name最好是CollectorDBCluster，network.host最好是局域网 IP，否则可能会在使用时出现很多问题
- 启动elasticsearch，注意：elasticsearch不能以root身份运行
groupadd elsearch
useradd elsearch -g elsearch -p elasticsearch
chown -R elsearch:elsearch elasticsearch
su elsearch
先运行命令 elasticsearch/bin/elasticsearch 查看是否运行成功，若是出现错误，请看 elasticsearch 异常归纳 进行解决
没问题后使用此命令在后台运行 nohup elasticsearch/bin/elasticsearch > elasticsearch/elasticsearch.log &
启动 elasticsearch 异常归纳（https://www.e-learn.cn/content/java/1069602）
SkyWorking安装
- 下载解压skywalking 5.0.0-GA
wget http://mirror.bit.edu.cn/apache/incubator/skywalking/5.0.0-GA/apache-skywalking-apm-incubating-5.0.0-GA.tar.gz
tar -vxf apache-skywalking-apm-incubating-5.0.0-GA.tar.gz
mv apache-skywalking-apm-incubating skywalking
- 修改配置 skywalking/config/application.yml

说明： naming host为0.0.0.0 其他都为skywalking部署所在服务器的局域网ip，，注意：elasticsearch的clusterNodes是elasticsearch所在服务器的ip+port，默认端口都为9300
- 修改配置 skywalking/webapp/webapp.yml
server:
port: 8080collector:
path: /graphql
ribbon:
ReadTimeout: 10000
listOfServers: 172.16.255.148:10800security:
user:
admin:
password: admin
- 修改配置 skywalking/agent/config/agent.config
agent.application_code=unkown //随意填写，可根据启动命令修改
collector.servers=172.16.255.148:10800
logging.level=INFO
- 启动 Collector 和 Webapp
skywalking/bin/startup.sh
- 单独启动 Collector 和 Webapp
skywalking/bin/collectorService.sh
skywalking/bin/webappService.sh
使用
说明：1、skywalking-agent.jar为安装的真实路径，可以linux下用 find / -name skywalking-agent.jar 查找
2、 -Dskywalking.agent.application_code=application 就是设置节点名称，如果是微服务，就写成服务名称即可
- Jar 启动时添加 VM 参数 ，例如：springboot打包的java应用（服务）为 application.jar
java -jar -javaagent:/opt/webapps/skywalking/agent/skywalking-agent.jar -Dskywalking.agent.application_code=application application.jar
- Tomcat 修改bin/catalina.sh首行配置（这个方式是参考其他来源，Jar方式已验证可行，具体情况以自己的环境为准）
# Linux/Mac
CATALINA_OPTS="$CATALINA_OPTS -javaagent:/path/to/skywalking-agent/skywalking-agent.jar"; export CATALINA_OPTS# Win
set "CATALINA_OPTS=-javaagent:/path/to/skywalking-agent/skywalking-agent.jar"
集群 （多服务不在同一台服务器中挂在SkyWalking上）
假设三台服务器：172.16.255.148 172.16.255.149 172.16.255.150
ElasticSearch和SkyWalking安装在172.16.255.148
application.jar服务在172.16.255.149
turntable.jar服务在172.16.255.150
- 拷贝SkyWalking中的agent目录所有东西到其他服务器中

SkyWalking拷贝的东西（172.16.255.149 172.16.255.150），然后启动命令同上即可
