获取编译好的文件

获取编译好的安装文件上传并解压/root/hd/azkaban-3.50.0 找到三个需要的配置文件 azkaban-db/build/distributions azkaban-web-server/build/distributions azkaban-exec-server/build/distributions distributions下就是我们需要的编译后的压缩文件把压缩文件分别分发到对应的服务器

在azkaban-db/build/distributions下只需获取create-all-sql-0.1.0-SNAPSHOT.sql 创建数据库表

分布式multiple-executor模式安装部署

任务分配如下

HOST 角色 node1 web-server node2 mysql node3 exec-server node4 exec-server

mysql

create database azkaban_data;

grant all privileges on azkaban_data.* to 'hive'@'%' identified by 'hive';

grant all privileges on azkaban_data.* to 'hive'@'localhost' identified by 'hive';

grant all privileges on azkaban_data.* to 'hive'@'hq555' identified by 'hive';

flush privileges;

source /root/hd/create-all-sql-0.1.0-SNAPSHOT.sql ;

注意如果导入数据过程报错索引过长更改数据库编码删除所有表重新导入数据

拷贝web-server到node1

解压

生成ssl

keytool -keystore keystore -alias jetty -genkey -keyalg RSA

注:密码和最后确认需要输入，其他默认即可。生成keystore复制到exe所在服务器为配置准备

设置web‐server

拷贝conf目录和log4j.properties

scp -r /root/azkaban-solo-server-0.1.0-SNAPSHOT/conf /root/azkaban-web-server-0.1.0-SNAPSHOT/
scp azkaban-3.42.0/azkaban-web-server/src/test/resources/log4j.properties azkaban-web-server-0.1.0-SNAPSHOT/conf/
vim azkaban-web-server-0.1.0-SNAPSHOT/conf/azkaban.properties

// 配置内容如下
azkaban.name=Test
azkaban.label=My Local Azkaban
azkaban.color=#FF3601
azkaban.default.servlet.path=/index
web.resource.dir=/root/hd/azkaban/azkaban-web-server-0.1.0-SNAPSHOT/web
default.timezone.id=Asia/Shanghai // 时间修改为上海

#如CpuStatus，过滤器会检查executor的cpu占用率是否达到95%，若达到95%，web-server也不会将任务交给该executor执行。可参考Azkaban Github源码。

#最后一次被分发
azkaban.executorselector.comparator.LastDispatched=1
#CPU
azkaban.executorselector.comparator.CpuUsage=1

注意涉及到路径都写绝对路径

设置plugins/jobtypes

mkdir -p plugins/jobtypes
vim commonprivate.properties
azkaban.native.lib=false
execute.as.user=false

添加用户azkaban-users.xml

<user username="admin" password="admin" roles="admin,metrics"/>
<user groups="azkaban" password="azkaban" roles="admin" username="azkaban"/>
<user password="metrics" roles="metrics" username="metrics"/>
<role name="admin" permissions="ADMIN"/>
<role name="metrics" permissions="METRICS"/>

拷贝exec-server到node3、node4

解压

从web-server拷贝conf目录、plugins目录到executor‐server下

注意conf/azkaban.properties配置的路径需要改如下

# Azkaban Personalization Settings
azkaban.name=Test
azkaban.label=My Local Azkaban
azkaban.color=#FF3601

在azkaban_data库executors表中添加executor

mysql> insert into executors(host,port,active) values("192.168.222.110",12321,1);
mysql> insert into executors(host,port,active) values("192.168.222.111",12321,1);

注:这里把active设置为1(激活状态)。
