|NO.Z.00034|——————————|^^ 部署 ^^|——|Hadoop&azkaban.V06|——|azkaban.v06|azkaban.multiple-executor模式部署.v02|

一、配置Azkaban-exec-server

### --- linux123节点，上传exec安装包到/opt/yanqi/software

[root@linux123 ~]# cd /opt/yanqi/software/azkaban/
[root@linux123 azkaban]# ll
-rw-r--r-- 1 root root 15762323 Jul 22  2020 azkaban-exec-server-0.1.0-SNAPSHOT.tar.gz

[root@linux123 azkaban]# tar -zxvf azkaban-exec-server-0.1.0-SNAPSHOT.tar.gz -C /opt/yanqi/servers/azkaban/

### --- 修改azkaban-exec-server的配置文件

[root@linux123 ~]# cd /opt/yanqi/servers/azkaban/azkaban-exec-server-0.1.0-SNAPSHOT/
[root@linux123 azkaban-exec-server-0.1.0-SNAPSHOT]# vim conf/azkaban.properties

# Azkaban Personalization Settings
azkaban.name=Test
azkaban.label=My Local Azkaban
azkaban.color=#FF3601
azkaban.default.servlet.path=/index
web.resource.dir=web/
default.timezone.id=Asia/Shanghai

# Azkaban UserManager class
user.manager.class=azkaban.user.XmlUserManager
user.manager.xml.file=conf/azkaban-users.xml

# Loader for projects
executor.global.properties=conf/global.properties
azkaban.project.dir=projects

# Where the Azkaban web server is located
azkaban.webserver.url=https://linux122:8443

# Azkaban mysql settings by default. Users should configure their own usernameand password.
database.type=mysql
mysql.port=3306
mysql.host=linux123
mysql.database=azkaban
mysql.user=root
mysql.password=12345678
mysql.numconnections=100

# Azkaban Executor settings
executor.maxThreads=50
executor.port=12321
executor.flow.threads=30

### --- 分发exec-server到linux121节点

[root@linux123 ~]# cd /opt/yanqi/servers/
[root@linux123 servers]# scp -r azkaban linux121:$PWD

二、启动服务

### --- 先启动exec-server再启动web-server

~~~     # 在linux121和linux123上启动start-exec-server
[root@localhost ~]# cd /opt/yanqi/servers/azkaban/azkaban-exec-server-0.1.0-SNAPSHOT/
[root@localhostazkaban-exec-server-0.1.0-SNAPSHOT]# bin/start-exec.sh

~~~     # 在linux122上启动start-web-server

[root@linux122 ~]# cd /opt/yanqi/servers/azkaban/azkaban-web-server-0.1.0-SNAPSHOT/
[root@linux122 azkaban-web-server-0.1.0-SNAPSHOT]#  bin/start-web.sh

### --- 查看启动的进程

[root@linux121 ~]# jps
9597 AzkabanExecutorServer
 
[root@linux123 ~]# jps
9855 AzkabanExecutorServer

[root@linux122 ~]# jps
9014 AzkabanWebServer

### --- 激活我们的exec-server：启动webServer之后进程失败消失，
~~~     可通过安装包根目录下对应启动日志进行排查。

[root@linux122 ~]#ll /opt/yanqi/servers/azkaban/azkaban-web-server-0.1.0-SNAPSHOT/
-rw-r--r-- 1 root root 82629 Sep  3 12:30 webServerLog_2021-09-03+12:26:43.out

[root@linux122 azkaban-web-server-0.1.0-SNAPSHOT]# tail -100 webServerLog_2021-09-03+12\:26\:43.out
# ERROR [ExecutorManager] [Azkaban] No active executor found

### --- 需要手动激活executor

~~~     # 在linux121和linux123激活executor
[root@localhost ~]# cd /opt/yanqi/servers/azkaban/azkaban-exec-server-0.1.0-SNAPSHOT/

~~~     # 请求webserver的地址，进行激活，把激活结果打印出来即可
[root@localhost ~]# curl -G "linux121:$(<./executor.port)/executor?action=activate" && echo
{"status":"success"}

三、访问地址：https://linux122:8443    用户名：azkaban    密码：azkaban
