安装

（1）Git下载源码

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

（2）在Azkaban目录下，gradlew压缩获取tar包

./gradlew distTar

（3）解压Azkaban的db、exec-server和web-server压缩包，并重命名

（4）将azkaban-db-3.73.0的create-all-sql-0.1.0-SNAPSHOT.sql导入mysql

（5）生成keystore证书

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

（6）将keystore证书移动到azkaban-web-server-3.73.0文件夹下

mv keystore azkaban-web-server-3.73.0/

（7）时间同步配置

sudo date -s '2019-05-05 21:25:00'
hwclock -w

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

（8）配置web-server的azkaban.properties文件
