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> CREATE DATABASE azkaban;
   2 mysql> CREATE USER ‘azkaban‘@‘%‘ IDENTIFIED BY ‘azkaban‘;
   3 mysql> CREATE USER ‘azkaban‘@‘localhost‘ IDENTIFIED BY ‘azkaban‘;
   4 mysql> grant all privileges on azkaban.* to ‘azkaban‘@‘%‘ identified by ‘azkaban‘;
   5 mysql> grant all privileges on 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

    1 # Azkaban Personalization Settings
    2 azkaban.name=nyhadoop
    3 azkaban.label=My Local Azkaban
    4 azkaban.color=#FF3601

   17 mysql.host=10.46.67.33
   18 mysql.database=azkaban
   19 mysql.user=azkaban
   20 mysql.password=azkaban
   21 mysql.numconnections=100
   22
   23 # Velocity dev mode
   24 velocity.dev.mode=false
   25 # Azkaban Jetty server properties.
   26 jetty.ssl.port=8443
   27 # jetty.use.ssl=false
   28 jetty.port=8081
   29 jetty.keystore=keystore
   30 jetty.password=123456
   31 jetty.keypassword=123456
   32 jetty.truststore=keystore
   33 jetty.trustpassword=123456
   34 jetty.maxThreads=25
   35 # Azkaban Executor settings
   36 executor.port=12321
   37 # mail settings
   38 mail.sender=
   39 mail.host=
   40 # User facing web server configurations used to construct the user facing server URLs. They are useful when there is a reverse proxy between Azkaban web servers and users.
   41 # enduser -> myazkabanhost:443 -> proxy -> localhost:8081
   42 # when this parameters set then these parameters are used to generate email links.
   43 # if these parameters are not set then jetty.hostname, and jetty.port(if ssl configured jetty.ssl.port) are used.
   44 # azkaban.webserver.external_hostname=myazkabanhost.com
   45 # azkaban.webserver.external_ssl_port=443
   46 # azkaban.webserver.external_port=8081
   47 job.failure.email=
   48 job.success.email=
   49 lockdown.create.projects=false
   50 cache.directory=cache
   51 # JMX stats
   52 jetty.connector.stats=true
   53 executor.connector.stats=true
   54 # Azkaban plugin settings
   55 azkaban.jobtype.plugin.dir=plugins/jobtypes
   56 azkaban.use.multiple.executors=true
   57 azkaban.executorselector.filters=StaticRemainingFlowSize,MinimumFreeMemory,CpuStatus
   58 azkaban.executorselector.comparator.NumberOfAssignedFlowComparator=1
   59 azkaban.executorselector.comparator.Memory=1
   60 azkaban.executorselector.comparator.LastDispatched=1
   61 azkaban.executorselector.comparator.CpuUsage=1

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
   What is your first and last name?
     [Unknown]:  直接回车
   What is the name of your organizational unit?
     [Unknown]:  直接回车
   What is the name of your organization?
     [Unknown]:  直接回车
   What is the name of your City or Locality?
     [Unknown]:  直接回车
   What is the name of your State or Province?
     [Unknown]:  直接回车
   What is the two-letter country code for this unit?
     [Unknown]:  直接回车
   Is CN=YY, OU=YY, O=YY, L=shanghai, ST=shanghai, C=CN correct?
     [no]:  y

8. 将生成的keystore文件 移动到/opt/Azkaban-web-server/目录下
9. 创建目录/opt/Azkaban-exec-server 并将azkaban-exec-server/build/distributions/下文件拷贝至此
10. 将azkaban-solo-server下conf 目录拷贝到/opt/Azkaban-exec-server目录下,修改其中azkaban.properties文件

    # Azkaban Personalization Settings
    default.timezone.id=Asia/Shanghai
    # Loader for projects
    executor.global.properties=conf/global.properties
    azkaban.project.dir=projects
    
    database.type=mysql
    mysql.port=3306
    mysql.host=10.46.67.33
    mysql.database=azkaban
    mysql.user=azkaban
    mysql.password=azkaban
    mysql.numconnections=100
    
    # Azkaban Executor settings
    executor.maxThreads=50
    executor.port=12321
    executor.flow.threads=30
    # JMX stats
    jetty.connector.stats=true
    executor.connector.stats=true
    # Azkaban plugin settings
    azkaban.jobtype.plugin.dir=plugins/jobtypes

11. 分别在/opt/Azkaban-web-server/conf和/opt/Azkaban-exec-server/conf目录下创建log4j.properties文件

    log4j.rootLogger=DEBUG,C
    log4j.appender.C=org.apache.log4j.ConsoleAppender
    log4j.appender.C.Target=System.err
    log4j.appender.C.layout=org.apache.log4j.PatternLayout
    log4j.appender.C.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

12. 分别在/opt/Azkaban-web-server/和/opt/Azkaban-exec-server/目录下创建plugins/jobtypes/commonprivate.properties目录和文件

    azkaban.native.lib=false
    execute.as.user=false

四.运行

1. /opt/Azkaban-exec-server目录下执行

   1 bin/start-exec.sh
   2 curl http://${executorHost}:${executorPort}/executor?action=activate

2. /opt/Azkaban-web-server目录下执行

   bin/start-web.sh
