Tinyid介绍

Tinyid是滴滴开发的一款分布式ID系统，Tinyid是在美团（Leaf）的leaf-segment算法基础上升级而来，不仅支持了数据库多主节点模式，还提供了tinyid-client客户端的接入方式，使用起来更加方便。但和美团（Leaf）不同的是，Tinyid只支持号段一种模式不支持雪花模式。

Tinyid的特性

• 全局唯一的long型ID
• 趋势递增的id
• 提供 http 和 java-client 方式接入
• 支持批量获取ID
• 支持生成1,3,5,7,9…序列的ID
• 支持多个db的配置

Tinyid部署

JDK部署

[root@localhost packages]# tar zxvf jdk-8u121-linux-x64.tar.gz
[root@localhost packages]# mv jdk1.8.0_121/ /usr/local/jdk
[root@localhost packages]# vim /etc/profile
##末尾添加
export JAVA_HOME=/usr/local/jdk 
export CLASSPATH=$:CLASSPATH:$JAVA_HOME/lib/ 
export PATH=$PATH:$JAVA_HOME/bin

[root@localhost packages]# source /etc/profile
[root@localhost packages]# java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

Maven部署

[root@localhost packages]# tar zxvf apache-maven-3.5.0-bin.tar.gz
[root@localhost packages]# mv apache-maven-3.5.0 /usr/local/maven
[root@localhost packages]# vim /etc/profile
##末尾添加
export MAVEN_HOME=/usr/local/maven 
export PATH=$MAVEN_HOME/bin:$PATH

[root@localhost packages]# source /etc/profile
[root@localhost packages]# mvn -version
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-04T03:39:06+08:00)
Maven home: /usr/local/maven

MySQL部署

[root@localhost ~]# yum -y install mariadb mariadb-server
[root@localhost ~]# systemctl enable mariadb
[root@localhost ~]# systemctl start mariadb
[root@localhost ~]# mysql -uroot 
mysql> set password = password('123456');
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;    //设置mysql外网连接密码
mysql> flush privileges;

Tinyid部署

## 拉取代码
[root@localhost local]# git clone https://github.com/didi/tinyid.git
[root@localhost local]# cd tinyid/tinyid-server/

## 导入SQL文件
[root@localhost tinyid-server]# mysql -uroot -p123456
mysql> create database tinyid;
mysql> use tinyid;
mysql> source /usr/local/tinyid/tinyid-server/db.sql;
mysql> exit

修改配置文件指定MySQL

[root@localhost tinyid-server]# vim src/main/resources/offline/application.properties

datasource.tinyid.primary.driver-class-name=com.mysql.jdbc.Driver
datasource.tinyid.primary.url=jdbc:mysql://localhost:3306/tinyid?autoReconnect=true&useUnicode=true&characterEncoding=UTF-8
datasource.tinyid.primary.username=root
datasource.tinyid.primary.password=123456

## 注意修mysql地址和库名称
jdbc:mysql://localhost:3306/tinyid?

启动tinyid

[root@localhost local]# cd tinyid/tinyid-server/ 
[root@localhost tinyid-server]# sh build.sh offline
[root@localhost tinyid-server]# java -jar output/tinyid-server-xxx.jar

[root@localhost tinyid-server]#  netstat -untpl | grep java
tcp        0      0 0.0.0.0:9999            0.0.0.0:*               LISTEN      12836/java 

自启动脚本

[root@localhost ~]# cd /usr/local/tinyid/tinyid-server

[root@localhost tinyid-server]# vim tinyid.sh

#!/bin/sh
##
if [ -f /etc/init.d/functions ]; then
        . /etc/init.d/functions
elif [ -f /etc/rc.d/init.d/functions ]; then
        . /etc/rc.d/init.d/functions
else
        echo -e "\aJnice: unable to locate functions lib. Cannot continue."
        exit 0
fi

ulimit -n 65000
echo 1024 65000 > /proc/sys/net/ipv4/ip_local_port_range

## jar文件名称
export JAVA_HOME=/usr/local/java/jdk1.8.0_181
export PATH=$JAVA_HOME/bin:$PATH:$PATH:/usr/ffmpeg/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
JAR_HOME=/usr/local/tinyid/tinyid-server/
JAR_NAME=tinyid-server-0.1.0-SNAPSHOT.jar

## 过滤pid进程号
tpid=`ps -ef|grep $JAR_NAME | grep -v grep | grep -v kill | awk '{print $2}'`
