oozie（1）：oozie安装步骤

一、准备工作

1.准备软件

oozie和ext2.2

2.Hadoop

3.mysql

建数据库

mysql> create database oozie;

二、安装和配置

1.上传解压oozie安装包

tar -zxvf oozie-4.1.0-cdh5.7.0.tar.gz -C /opt/modules/

2.修改hadoop里面的core-site.xml

（1）修改core-site.xml 

#root替换为自己用户名
<property>
	<name>hadoop.proxyuser.root.hosts</name>
	<value>*</value>
</property>
<property>
	<name>hadoop.proxyuser.root.groups</name>
	<value>*</value>
</property>

（2）重启hadoop集群服务

sbin/start-dfs.sh
sbin/start-yarn.sh

启动history
sbin/mr-jobhistory-daemon.sh start historyserver

3.生成libext目录,并拷贝相关的jar包

（1）oozie安装目录下

mkdir libext

（2）oozie安装目录同级目录下解压oozie-hadooplibs-4.1.0-cdh5.7.0.tar.gz

tar -zxvf oozie-hadooplibs-4.1.0-cdh5.7.0.tar.gz -C /opt/modules/

     解压缩后，在/opt/modules/oozie-4.1.0-cdh5.7.0目录下会增加hadooplibs包！

（3）拷贝解压出来的jar包到{OOZIE_HOME}/libext

cp hadooplibs/hadooplib-2.6.0-cdh5.7.0.oozie-4.1.0-cdh5.7.0/* /opt/modules/oozie-4.1.0-cdh5.7.0/libext/

（4）拷贝ext-2.2.zip到{OOZIE_HOME}/libext

cp /opt/software/ext-2.2.zip libext/

（5）拷贝mysql的驱动包到{OOZIE_HOME}/libext里面

cp /opt/modules/hive-1.1.0-cdh5.7.0/lib/mysql-connector-java-5.1.27-bin.jar /opt/modules/oozie-4.1.0-cdh5.7.0/libext/

4.修改oozie配置文件 {OOZIE_HOME}/conf/oozie-site.xml

<property>
	<name>oozie.service.JPAService.jdbc.driver</name>
	<value>com.mysql.jdbc.Driver</value>
</property>
<property>
	<name>oozie.service.JPAService.jdbc.url</name>
	<value>jdbc:mysql://hadoop:3306/oozie</value>
</property>
<property>
	<name>oozie.service.JPAService.jdbc.username</name>
	<value>root</value>
</property>
<property>
	<name>oozie.service.JPAService.jdbc.password</name>
	<value>123456</value>
</property>
** 关联HDFS
<property>
	<name>oozie.service.HadoopAccessorService.hadoop.configurations</name>
	<value>*=/opt/modules/hadoop-2.6.0-cdh5.7.0/etc/hadoop</value>
</property>

5、依次执行以下命令

（1）在{OOZIE_HOME}，生产web工程（war）

bin/oozie-setup.sh prepare-war

（2）如果报错

unzip: command not found

是因为centOS默认没有unzip解压缩命令，所以解决是安装unzip

yum install -y unzip zip

（3）上传包到HDFS

bin/oozie-setup.sh sharelib create \
-fs hdfs://hadoop:8020 \
-locallib oozie-sharelib-4.1.0-cdh5.7.0-yarn.tar.gz

（4）生成数据库

bin/oozie-setup.sh db create -run -sqlfile oozie.sql

结果：

setting CATALINA_OPTS="$CATALINA_OPTS -Xmx1024m"

Validate DB Connection
DONE
Check DB schema does not exist
DONE
Check OOZIE_SYS table does not exist
DONE
Create SQL schema
DONE
Create OOZIE_SYS table
DONE

Oozie DB has been created for Oozie version '4.1.0-cdh5.7.0'

The SQL commands have been written to: oozie.sql

（5）检测成功生成的数据库

（a）mysql数据库中

use oozie;
show tables;
结果
mysql> show tables;
+------------------------+
| Tables_in_oozie        |
+------------------------+
| BUNDLE_ACTIONS         |
| BUNDLE_JOBS            |
| COORD_ACTIONS          |
| COORD_JOBS             |
| OOZIE_SYS              |
| OPENJPA_SEQUENCE_TABLE |
| SLA_EVENTS             |
| SLA_REGISTRATION       |
| SLA_SUMMARY            |
| VALIDATE_CONN          |
| WF_ACTIONS             |
| WF_JOBS                |
+------------------------+
12 rows in set (0.00 sec)

（b）oozie.sql文件：刚刚创建的oozie数据库中数据表的所有sql语句

cat /opt/modules/oozie-4.1.0-cdh5.7.0/oozie.sql
结果：
...
CREATE INDEX I_WF_CTNS_PENDING_AGE ON WF_ACTIONS (pending_age);
CREATE INDEX I_WF_CTNS_STATUS ON WF_ACTIONS (status);
CREATE INDEX I_WF_CTNS_WF_ID ON WF_ACTIONS (wf_id);
CREATE INDEX I_WF_JOBS_END_TIME ON WF_JOBS (end_time);
CREATE INDEX I_WF_JOBS_EXTERNAL_ID ON WF_JOBS (external_id);
CREATE INDEX I_WF_JOBS_LAST_MODIFIED_TIME ON WF_JOBS (last_modified_time);
CREATE INDEX I_WF_JOBS_PARENT_ID ON WF_JOBS (parent_id);
CREATE INDEX I_WF_JOBS_STATUS ON WF_JOBS (status);

create table OOZIE_SYS (name varchar(100), data varchar(100))
insert into OOZIE_SYS (name, data) values ('db.version', '3')
insert into OOZIE_SYS (name, data) values ('oozie.version', '4.1.0-cdh5.7.0')

6.启动服务

bin/oozied.sh start

7.测试前端页面oozie

http://hadoop:11000/oozie/

  

8.oozie停止脚本

bin/oozie-stop.sh
