azkaban 编译部署

安装azkaban单机版和集群版

一、安装单机版

1、安装git

yum install git

2、拉取azkaban源码

git clone https://github.com/azkaban/azkaban.git

3、开始编译

cd azkaban; 
开始编译
./gradlew build installDist

编译过程很漫长，一直在下载包，可能出现超时的情况，然后再继续编译就好

如果出现JCE报错，则需要手动下载相关的包

　　解决方法：
下载JCE
https://www.oracle.com/technetwork/cn/java/javase/downloads/jce8-download-2133166-zhs.html
我这边使用的JDK8，包含了JCE所需要的jre8 ，解压出来，放到jdk安装目录的 jre/lib/security下面

参考 https://yq.aliyun.com/articles/648399

4、启动服务

cd azkaban-solo-server/build/install/azkaban-solo-server; 
bin/start-solo.sh

注意，这里不能直接进入到bin目录启动，否则会报找不到database.properties的错误

java.io.IOException: Cannot find 'database.properties' file in /opt/local/azkaban-solo-server/build/install/azkaban-solo-server/bin/sql/database.properties
	at azkaban.database.AzkabanDatabaseSetup.loadDBProps(AzkabanDatabaseSetup.java:178)
	at azkaban.database.AzkabanDatabaseSetup.loadTableInfo(AzkabanDatabaseSetup.java:102)
	at azkaban.database.AzkabanDatabaseUpdater.runDatabaseUpdater(AzkabanDatabaseUpdater.java:82)
	at azkaban.soloserver.AzkabanSingleServer.start(AzkabanSingleServer.java:93)
	at azkaban.soloserver.AzkabanSingleServer.main(AzkabanSingleServer.java:58)

参考： https://blog.csdn.net/SUDDEV/article/details/101369524

5、查看服务

访问 http://ip:8081

默认账号密码是 azkaban azkaban

6、停止服务

bin/shutdown-solo.sh

7、如果是离线安装，可以在可以上网的机器编译，然后将编译好后的

azkaban/azkaban-solo-server/build/install/azkaban-solo-server 复制到安装机器上，然后启动即可。

二、安装集群版

1、在上面编译好的目录中，azkaban-solo-server是单机版服务，azkaban-exec-server是后台服务，azkaban-web-server 是网页服务
我们现在需要在上面编译好的文件中，将后台服务和网页服务复制到安装目录

cp -r azkaban/azkaban-exec-server/build/install/azkaban-exec-server /opt/local
cp -r azkaban/azkaban-web-server/build/install/azkaban-web-server /opt/local

2、创建azkaban依赖的MySQL数据库

mysql> CREATE DATABASE azkaban;

3、生成初始化MySQL数据库文件

cd azkaban/azkaban-db
../gradlew build installDist

文件在azkaban/azkaban-db/build/sql，放到MySQL执行

4、配置和启动后台服务

cd /opt/local/azkaban-exec-server/conf
vim azkaban.properties，修改MySQL配置、时区

default.timezone.id=Asia/Shanghai

mysql.port=3306
mysql.host=数据库ip
mysql.database=azkaban
mysql.user=数据库账号
mysql.password=数据库密码

启动服务

bin/start-exec.sh

5、配置和启动网页服务

cd /opt/local/azkaban-web-server/conf

vim azkaban.properties

default.timezone.id=Asia/Shanghai

mysql.port=3306
mysql.host=数据库ip
mysql.database=azkaban
mysql.user=数据库账号
mysql.password=数据库密码

启动服务 bin/start-web.sh

然后发现报错了，发现没有可用的executor

我们改一下数据库，激活executor

use azkaban;
update azkaban.executors set active=1;

再启动一次服务，即可

对于集群部署，将azkaban-web-server按照上面的步骤部署，然后执行 curl -G "http:ip:port/executor?action=activate" 激活节点，或者去MySQL改数据激活
