环境准备

jdk8+

mysql

节点划分

centosx1centosx2centosx3
web-server
exe-serverexe-server
mysql

这里编辑了hosts文件,关闭了selinux和firewalld

[root@centos7x3 azkaban-exec-server]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

部署步骤

构建编译

​ gradle又臭又长,暂时省略

​ 获得需要的三个文件夹

azkaban-db-3.84.4.tar.gz           #数据库文件
azkaban-web-server-3.84.4.tar.gz   #web-server文件
azkaban-exec-server-3.84.4.tar.gz  #exe-server文件

  • 2
  • 3

理论上启动什么服务就拷贝什么文件，一起拷贝以后切换节点方便。

把azkaban-web-server-3.84.4.tar.gz 解压重命名到/user/local/azkaban/azkaban-web-server

把azkaban-exec-server-3.84.4.tar.gz 解压重命名到/user/lobal/azkaban/azkaban-exec-server

初始化数据库

解压azkaban-db-3.84.4.tar.gz，得到其中的create-all-sql-3.84.4.sql

[root@centos7x1 azkaban-db-3.84.4]# ls
......
create-all-sql-3.84.4.sql
......

进入数据库

# 建立库
mysql> create database azkaban default character set utf8mb4;
# 建立账号
mysql> grant all privileges on azkaban.* to 'azkaban'@'%' identified by 'azkaban';
mysql> flush privileges;
mysql> exit;
[root@centos7x1 azkaban-db-3.84.4]# mysql -uazkaban -p azkaban < create-all-sql-3.84.4.sql

配置exe-server

编辑配置文件azkaban-exec-server/conf/azkaban.properties ,与web-server大体是一样的，只是web-server多了选择exe节点的相关配置

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

azkaban.default.servlet.path=/index
web.resource.dir=/usr/local/azkaban/azkaban-web-server/web

azkaban.project.dir=projects
# Velocity dev mode
velocity.dev.mode=false
# Azkaban Jetty server properties.
jetty.use.ssl=false
jetty.maxThreads=25
jetty.port=8081
# Where the Azkaban web server is located
azkaban.webserver.url=http://localhost:8081
# mail settings

# 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.

[root@centos7x1 local]# scp /usr/local/azkaban/ root@centos7x3:/usr/local

启动系统

原则是先启动exe再启动web

启动exe-server节点

先cd到目录里，在start，因为系统会在当前目录创建几个文件（端口和日志等）

[root@centos7x2 azkaban-exec-server]# cd /usr/local/azkaban/azkaban-exec-server/
[root@centos7x2 azkaban-exec-server]# bin/start-exec.sh 
[root@centos7x2 azkaban-exec-server]# ls
bin  conf  currentpid  executions  executor.port  executorServerLog__2020-06-27+14:27:02.out  lib  logs  plugins  projects  temp

激活exe节点

进入到mysql,可以看到有两个节点进行了注册，修改actvie=0为1，激活节点

mysql> select * from executors;
+----+-----------+-------+--------+
| id | host      | port  | active |
+----+-----------+-------+--------+
|  4 | centos7x3 | 37454 |      0 |
|  5 | centos7x2 | 38088 |      0 |
+----+-----------+-------+--------+
2 rows in set (0.04 sec)

mysql> update executors set active=1;
Query OK, 2 rows affected (0.00 sec)
Rows matched: 2  Changed: 2  Warnings: 0

mysql> select * from executors;
+----+-----------+-------+--------+
| id | host      | port  | active |
+----+-----------+-------+--------+
|  4 | centos7x3 | 37454 |      1 |
|  5 | centos7x2 | 38088 |      1 |
+----+-----------+-------+--------+
2 rows in set (0.02 sec)

启动web-server节点

同样先cd到目录，在运行start-web.sh

[root@centos7x1 azkaban-exec-server]# cd /usr/local/azkaban/azkaban-web-server/
[root@centos7x1 azkaban-web-server]# bin/start-web.sh 
[root@centos7x1 azkaban-web-server]# ls
bin  conf  currentpid  lib  logs  temp  web  webServerLog_2020-06-27+14:27:53.out
[root@centos7x1 azkaban-web-server]#

成功后访问http://172.16.79.101:8081/

一些问题

解决executor不激活问题

有时候 启动的时候报这个错误，节点不自动激活，此时需要手动激活一下。

2020/06/27 14:51:56.580 +0800 ERROR [ExecutorServlet] [Azkaban] executor became inactive before setting up the flow 24
azkaban.executor.ExecutorManagerException: executor became inactive before setting up the flow 24

手动激活 Executor方法：

端口号可以在executor.port中查看，或者在数据库中executors表中。

mysql> select * from executors;
+----+-----------+-------+--------+
| id | host      | port  | active |
+----+-----------+-------+--------+
|  4 | centos7x3 | 37454 |      1 |
|  5 | centos7x2 | 38088 |      1 |
+----+-----------+-------+--------+
