 一.Azkaban部署流程

1>.上传azkaban程序并创建解压目录

[yinzhengjie@s101 data]$ pwd
/home/yinzhengjie/data
[yinzhengjie@s101 data]$ ll
total
-rw-r--r--  yinzhengjie yinzhengjie   Apr  : azkaban-exec-server-3.46..tar.gz
-rw-r--r--  yinzhengjie yinzhengjie      Apr  : azkaban-hadoop-security-plugin-3.46..tar.gz
-rw-r--r--  yinzhengjie yinzhengjie  Apr  : azkaban-plugins-master.zip
-rw-r--r--  yinzhengjie yinzhengjie   Apr  : azkaban-solo-server-3.46..tar.gz
-rw-r--r--  yinzhengjie yinzhengjie   Apr  : azkaban-web-server-3.46..tar.gz
-rw-r--r--  yinzhengjie yinzhengjie      Nov    create-all-sql-3.46..sql
[yinzhengjie@s101 data]$
[yinzhengjie@s101 data]$ mkdir /soft/azkaban
[yinzhengjie@s101 data]$ 

2>.分别解压文件到/soft/azkaban中

[yinzhengjie@s101 data]$ tar -xzf azkaban-exec-server-3.46..tar.gz -C /soft/azkaban/
[yinzhengjie@s101 data]$ tar -xzf azkaban-web-server-3.46..tar.gz -C /soft/azkaban/
[yinzhengjie@s101 data]$ 

3>.进入到mysql命令行并创建数据库

[yinzhengjie@s101 data]$ mysql -uroot -pyinzhengjie

mysql> exit;

4>.创建SSL配置（完成下述工作后,将在当前目录生成 keystore 证书文件，需要输出初始密码，选择国家，在输入确认字母y其他按回车即可）

[yinzhengjie@s101 data]$ keytool -keystore keystore -alias jetty -genkey -keyalg RSA
Enter keystore password:
Re-enter new password:
What is your first and last name?
  [Unknown]:
What is the name of your organizational unit?
  [Unknown]:
What is the name of your organization?
  [Unknown]:
What is the name of your City or Locality?
  [Unknown]:
What is the name of your State or Province?
  [Unknown]:
What is the two-letter country code for this unit?
  [Unknown]:  CN
Is CN=Unknown, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=CN correct?
  [no]:  y

Enter key password for <jetty>
    (RETURN if same as keystore password):
[yinzhengjie@s101 data]$
[yinzhengjie@s101 data]$ ll | grep keystore
-rw-rw-r--  yinzhengjie yinzhengjie       Jun  : keystore
[yinzhengjie@s101 data]$ 

5>.将keystore文件拷贝到web文件夹下

[yinzhengjie@s101 data]$ ll | grep keystore
-rw-rw-r--  yinzhengjie yinzhengjie       Jun  : keystore
[yinzhengjie@s101 data]$ cp keystore /soft/azkaban/azkaban-web-server-3.46./
[yinzhengjie@s101 data]$ 

6>.编辑配置文件【azkaban.properties】

[yinzhengjie@s101 data]$ more /soft/azkaban/azkaban-web-server-3.46./conf/azkaban.properties

　　以上代码只是对该配置文件的一个详细说明，不建议在这个配置文件中写中文！在实际配置中，需要将这个文件拷贝两份，分别放在web和exec目录中，实际使用配置如下：

[yinzhengjie@s101 ~]$ 

[yinzhengjie@s101 ~]$ more /soft/azkaban/azkaban-exec-server-3.46.0/conf/azkaban.properties

7>.修改用户配置文件【azkaban-users.xml】

[yinzhengjie@s101 data]$ more /soft/azkaban/azkaban-web-server-3.46./conf/azkaban-users.xml
<azkaban-users>
    <user username="azkaban" password="yinzhengjie" roles="admin" groups="azkaban" />
    <user username="metrics" password="yinzhengjie" roles="metrics"/>
    <user username="admin" password="yinzhengjie" roles="admin,metrics" />
    <role name="admin" permissions="ADMIN" />
    <role name="metrics" permissions="METRICS"/>
</azkaban-users>
[yinzhengjie@s101 data]$ 

8>.创建global.properties

[yinzhengjie@s101 data]$ touch /soft/azkaban/azkaban-web-server-3.46./conf/global.properties
[yinzhengjie@s101 data]$ 

9>.编写启动脚本

[yinzhengjie@s101 ~]$ more /usr/local/bin/azweb.sh
#!/bin/bash
#@author :yinzhengjie
#blog:http://www.cnblogs.com/yinzhengjie
#EMAIL:y1053419035@qq.com

#判断用户是否传参
if [ $# -ne  ];then
    echo "无效参数，用法为: $0  {start|stop}"
    exit
fi

#获取用户输入的命令
cmd=$
case $cmd in
    start)
        cd /soft/azkaban
        /soft/azkaban/azkaban-web-server-3.46./bin/start-web.sh
        ;;
    stop)
        cd /soft/azkaban
        /soft/azkaban/azkaban-web-server-3.46./bin/shutdown-web.sh
        ;;
    *)
        echo "无效参数，用法为: $0  {start|stop}"
        exit
        ;;
esac
echo ========= azweb $cmd =============
[yinzhengjie@s101 ~]$ 

web端启动脚本（/usr/local/bin/azweb.sh）

[yinzhengjie@s101 ~]$ more /usr/local/bin/azexec.sh
#!/bin/bash
#@author :yinzhengjie
#blog:http://www.cnblogs.com/yinzhengjie
#EMAIL:y1053419035@qq.com

    start)
        cd /soft/azkaban
        /soft/azkaban/azkaban-exec-server-3.46./bin/start-exec.sh
        ;;
    stop)
        cd /soft/azkaban
        /soft/azkaban/azkaban-exec-server-3.46./bin/shutdown-exec.sh
        ;;
    *)
        echo "无效参数，用法为: $0  {start|stop}"
        exit
        ;;
esac
echo ========= azexec $cmd =============
[yinzhengjie@s101 ~]$ 

exec端启动脚本（/usr/local/bin/azexec.sh）

10>.启动服务（启动web和executor）

[yinzhengjie@s101 ~]$ jps
 Jps
[yinzhengjie@s101 ~]$
[yinzhengjie@s101 ~]$ azweb.sh start
========= azweb start =============
[yinzhengjie@s101 ~]$ azexec.sh start
========= azexec start =============
[yinzhengjie@s101 ~]$ jps
 AzkabanExecutorServer
 AzkabanWebServer
 Jps
[yinzhengjie@s101 ~]$ netstat -untalp | grep
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp6              :::                 :::*                    LISTEN      /java
[yinzhengjie@s101 ~]$ 

11>.测试azkaban连接

　　输入用户名和密码信息：

　　登录成功会有以下页面：

 二. Azkaban防坑小技巧

1>.job文件有空格

　　解决方案：

　　　　　　修改command.job配置文件，将里面多余的空格删除掉！然后重新上传job任务。

2>.Missing required property 'azkaban.native.lib'

　　解决方案：

[yinzhengjie@s101 ~]$ grep azkaban.jobtype.plugin.dir /soft/azkaban/azkaban-web-server-3.46.0/conf/azkaban.properties
azkaban.jobtype.plugin.dir=/soft/azkaban/azkaban-exec-server-3.46.0/plugins/jobtypes/
[yinzhengjie@s101 ~]$
[yinzhengjie@s101 ~]$ grep azkaban.jobtype.plugin.dir  /soft/azkaban/azkaban-exec-server-3.46.0/conf/azkaban.properties
azkaban.jobtype.plugin.dir=/soft/azkaban/azkaban-exec-server-3.46.0/plugins/jobtypes/
[yinzhengjie@s101 ~]$ 

编辑“azkaban.properties” 配置文件，然后需要重启Azkaban服务！
