azkaban安装与使用

1.      下载azkaban3.25的”source code.tar.gz”: https://github.com/azkaban/azkaban/releases

2.      解压缩：azkaban-3.25.0.tar.gz，进入azkaban根目录：cd azkaban-3.25.0

3.      执行命令：./gradlew installDist  生成相关文件

4.      创建一个新的文件夹：mkdir azkaban ,复制以下文件内容到XXX目录下：

cp /azkaban-3.25.0/azkaban-web-server/build/install/azkaban-web-server  azkaban

cp /azkaban-3.25.0/azkaban-exec-server/build/install/azkaban-exec-server azkaban

cp /azkaban-3.25.0/azkaban-db/build/install/azkaban-web-server azkaban

5.      在mysql数据库中创建一个数据库：azkaban 

进入azkaban数据库：use Azkaban 

执行：source /azkaban-3.25.0/azkaban-db/create-all-sql-0.1.0-SNAPSHOT.sql

6.      创建SSL配置：keytool -keystore keystore -alias jetty -genkey -keyalg RSA

提示中只需填写个6位密码即可，其他信息可填可不填

将生成的keystore文件拷贝至XXX目录下：cpkeystore /XXX/azkaban-web-server

7.      先配置好服务器节点上的时区

先生成时区配置文件Asia/Shanghai，用交互式命令 tzselect 即可

拷贝该时区文件，覆盖系统本地时区配置

cp/usr/share/zoneinfo/Asia/Shanghai /etc/localtime

8.      配置azkaban-web-server的conf下的文件：

<azkaban-users>

<user username="azkaban"password="azkaban" roles="admin" groups="azkaban"/>

<user username="metrics"password="metrics" roles="metrics"/>

<user username="admin"password="admin" roles="admin,metrics" />

<role name="admin"permissions="ADMIN" />

<role name="metrics"permissions="METRICS"/>

</azkaban-users>

 

配置log4j.properties

log4j.rootLogger=INFO,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-ddHH:mm:ss} %-5p %c{1}:%L - %m%n

 

 

 

9.      配置azkaban-exec-server的conf下的文件

database.type=mysql

mysql.port=3306

mysql.host=localhost

mysql.database=azkaban

mysql.user=root

mysql.password=1234

mysql.numconnections=100

 

# AzkabanExecutor settings

executor.maxThreads=50

executor.port=12321

executor.flow.threads=30

 

# JMXstats

jetty.connector.stats=true

executor.connector.stats=true

 

log4j.properties

log4j.rootLogger=INFO,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-ddHH:mm:ss} %-5p %c{1}:%L - %m%n

 

配置/plugins/jobtypes/commonprivate.proterties

# setexecute-as-user

execute.as.user=false

#关闭内存检查，若可用内存空间小于3GB会报错

memCheck.enabled=false

 

10.  测试

新建一个任务：command.job

vi command.job

#command.job

type=command

command=echo 'hello azkaban'

 

将command.job打包成zip文件：zipcommand.job

在浏览器中输入url：https://localhost:8443,输入配置好的用户和密码，进入azkaban web client

点击[Create Project]，输入项目名和描述

上传command.job.zip

执行流

 

 注：过程中可能遇到的错误：

①若azkaban-web-server和azkaban-exec-server的目录conf无log4j.properties文件则会报以下错误：

Exception: java.lang.StackOverflowError thrown from the UncaughtExceptionHandler in thread "main"

②若/azkaban-exec-server/plugins/jobtypes/下commonprivate.proterties文件未配置，则会报以下错误：
