CentOS搭建基于ZIPKIN的数据追踪系统
配置Java环境
Zipkin使用Java1.8（拖包）
[root@localhost ~]# tar zxf jdk-8u201-linux-x64.tar.gz
[root@localhost ~]# mv jdk1.8.0_201/ /usr/local/java
[root@localhost ~]# vim /etc/profile
export JAVA_HOME=/usr/local/java
export JRE_HOME=/usr/local/java/jre/
export CLASSPATH=$JAVA_HOME/lib:$JRE_HOME/lib
export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
[root@localhost ~]# rm -rf /usr/bin/java
[root@localhost ~]# source /etc/profile
[root@localhost ~]# java -version
java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)安装Zipkin
新建目录
[root@localhost ~]# mkdir -p /data/release/zipkin && cd "$_"下载Zipkin
[root@localhost zipkin]# wget -O zipkin.jar 'https://search.maven.org/remote_content?g=io.zipkin.java&a=zipkin-server&v=LATEST&c=exec'启动Zipkin，阻塞模式
[root@localhost ~]# java -jar /data/release/zipkin/zipkin.jar以MySQL为例做数据持久化方案
安装MySQL5.7
将以上阻塞打断
下载MySQL
[root@localhost ~]# wget http://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm安装rpm包
[root@localhost ~]# rpm -Uvh mysql57-community-release-el7-9.noarch.rpm安装MySQL
[root@localhost ~]# yum install mysql-community-server -y启动MySQL服务
[root@localhost ~]# systemctl start mysqld设置MySQL密码
[root@localhost ~]# grep 'temporary password' /var/log/mysqld.log | awk '{print $NF}'
Tb#phSu!B4hQ
[root@localhost ~]# mysql -uroot -p
# 复制以上的密码即可修改MySQL的root密码
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456.CoM';
Query OK, 0 rows affected (0.02 sec)
mysql> exit
Bye初始化Zipkin数据库
编写初始化脚本
请在 /data/release/zipkin 目录下创建 zipkin_init.sql
示例代码：/data/release/zipkin/zipkin_init.sql
[root@localhost ~]# vim /data/release/zipkin/zipkin_init.sql

[root@localhost ~]# mysql -uroot -p123456.CoM创建zipkin数据库，并将刚才的实例sql文件导入
mysql> CREATE DATABASE zipkin;

mysql> use zipkin;
Database changed
mysql> source /data/release/zipkin/zipkin_init.sql
mysql> show tables;

Bye启动Zipkin
[root@localhost ~]# cd /data/release/zipkin/
[root@localhost zipkin]# STORAGE_TYPE=mysql MYSQL_HOST=localhost MYSQL_TCP_PORT=3306 MYSQL_DB=zipkin \
MYSQL_USER=root MYSQL_PASS='123456.CoM' \
nohup java -jar zipkin.jar > /dev/null 2>&1 &创建具有数据上报能力的Demo
安装Node.js
下载Node.js的源码安装包
[root@localhost ~]# wget https://npm.taobao.org/mirrors/node/v14.0.0/node-v14.0.0-linux-x64.tar.xz解压Node.js源码包
[root@localhost ~]# tar xf node-v14.0.0-linux-x64.tar.xz添加Node.js的命令到系统环境变量中
[root@localhost ~]# mv node-v14.0.0-linux-x64 /usr/local/nodejs
[root@localhost ~]# vim /etc/profile
# 末尾添加
export PATH=$PATH:/usr/local/nodejs/bin
[root@localhost ~]# source /etc/profile
[root@localhost ~]# node -v
v14.0.0创建Demo目录
[root@localhost zipkin]# mkdir /data/release/service_a请在 /data/release/service_a 目录下创建并编辑 package.json，

app.use('/', (req, res, next) => {
res.send('hello world\n');
});
app.listen(3001, () => {
console.log('service-a listening on port 3001!')
