azkaban的部署

随着平台上的任务越来越多,且部分任务相互依赖,目前使用的crontab定时调度已经无法满足使用需求.急需一个任务依赖调度系统,笔者以前使用过oozie,但是oozie配置过多,而且维护繁琐,属于重量级系统.所以最终我选择使用azkaban.网上关于oozie和azkaban比较的文章很多,有兴趣可以自行百度.接下来说说azkaban的部署.

一.部署模式

• 单机模式(solo)
• 单机集群(1个webServer,1个execServer)
• 集群模式(1个webServer,多个execServer)
  本文选择第三种模式,即一台机器安装webServer服务,多台机器安装execServer.这种模式是使用最广泛的.

二.部署准备

1. 需要一个mysql服务器,创建azkaban库,azkaban用户密码,并赋予远程连接.
   
   

   1 mysql>CREATEDATABASE azkaban;
   2 mysql>CREATEUSER‘azkaban‘@‘%‘ IDENTIFIED BY‘azkaban‘;
   3 mysql>CREATEUSER‘azkaban‘@‘localhost‘ IDENTIFIED BY‘azkaban‘;
   4 mysql>grantallprivilegeson azkaban.*to‘azkaban‘@‘%‘ identified by‘azkaban‘;
   5 mysql>grantallprivilegeson azkaban.*to‘azkaban‘@‘localhost‘ identified by‘azkaban‘;
   6 mysql> flush privileges;

2. 下载最新azkaban源文件(azkaban-3.47.0.tar.gz)

三.开始部署

1. 解压下载的文件azkaban-3.47.0.tar.gz 
2. 进入目录执行下面代码编译源文件
   

   ./gradlew distTar

3. 解压编译好的文件,目录如下:
   

   azkaban-exec-server/build/distributions/
   azkaban-web-server/build/distributions/
   azkaban-solo-server/build/distributions/
   azkaban-db/build/distributions/

4. 导入建表语句
   

   mysql -uazkaban -p
   > SOURCE XXX/create-all-sql-0.1.0-SNAPSHOT.sql;

5. 创建目录/opt/Azkaban-web-server 并将azkaban-web-server/build/distributions/下文件拷贝至此
6. 将azkaban-solo-server下conf 目录拷贝到/opt/Azkaban-web-server目录下,修改其中azkaban.properties文件

7. 配置jetty ssl
   
   

   keytool -keystore keystore -alias jetty -genkey -keyalg RSA
   Enter keystore password:  输入密码
   Re-enter new password: 再次输入密码
