Start to use skywalking

• Install JDK8
• Install ES
• Install skywalking
• Run Springboot JAR

Install JDK8

If you have installed jdk8, and you can get JAVA_HOME path by

echo $JAVA_HOME

, then please skip this step.

yum install -y java-1.8.0-openjdk-devel.x86_64
           

Install ES

docker pull elasticsearch:6.5.4
docker create --name my_elasticsearch --net host -e "discovery.type=single-node" -e "network.host=172.16.55.xxxthe server internal ip" elasticsearch:6.5.4
docker start my_elasticsearch
docker logs my_elasticsearch
           

Install skywalking

Official link to download skywalking:

http://skywalking.apache.org/downloads/

tar -zxvf ...
./bin/startup.sh
           

Now you can visit port 8080… see the page below

Run Springboot JAR

A few steps:

1. Copy the

   entire folder

   called

   agent

   to your server, we will need its absolute path

   You will get the folder

   agent

   when you uncompress the file you download from official site.
2. vim

   agent.config

   under

   /agent/config/

agent.service_name=${SW_AGENT_NAME:PartyTest_1}
collector.backend_service=${SW_AGENT_COLLECTOR_BACKEND_SERVICES:192.xxx.xxx.xxx:11800}
           

Explain:

PartyTest_1

is your project name

192.xxx.xxx.xxx

is your server ip

11800

keep it and the rest

1. create

   startUpSky.sh

   and start it.

#!/bin/bash
str=$1
str1=${str%-*}
str2=${str1%-*}
nohup /usr/local/jdk1.8.0_162/bin/java -javaagent:/opt/devlop/agent/skywalking-agent.jar -Dskywalking.agent.service_name=${str2} -jar -XX:MetaspaceSize=256m -XX:MaxMetaspaceSize=256m -Xms512m -Xmx512m -Xmn256m -Xss256k -XX:SurvivorRatio=8 -XX:+UseConcMarkSweepGC $1 > logs/$1.out &
           

Explain:

str2=${str1%-*}

better use your own

/usr/local/jdk1.8.0_162/bin/java

if you installed jdk manually, get the path by

echo $JAVA_HOME

, else you can get the path following below

[[email protected]_0_13_centos ~]# whereis javac
javac: /usr/bin/javac /usr/share/man/man1/javac.1.gz
[[email protected]_0_13_centos ~]# ll /usr/bin/javac
lrwxrwxrwx 1 root root 23 Sep 19 11:35 /usr/bin/javac -> /etc/alternatives/javac
[[email protected]_0_13_centos ~]# ll /etc/alternatives/javac
lrwxrwxrwx 1 root root 70 Sep 19 11:35 /etc/alternatives/javac -> /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-1.el7_7.x86_64/bin/javac
           

Take this part /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-1.el7_7.x86_64/bin/java

-Dskywalking.agent.service_name=${str2}

to define the name on the skywalking board, of cource you can put a name there directly as well
