引言
Oozie是Hadoop生态系统中的工作流控制组件，可以调度MR，Hive，Shell等各类任务，并配置复杂的工作流程。
今天介绍如何安装部署，使用的是单机测试环境。

下载解压
下载安装过程需要的相关文件：
oozie4.0.0安装包
http://archive.cloudera.com/cdh5/cdh/5/oozie-4.0.0-cdh5.2.0.tar.gz
ext2.2包
http://extjs.com/deploy/ext-2.2.zip
存在在/home/casliyang/Downloads/ext-2.2.zip
将oozie4.0.0安装包解压拷贝到：
/home/casliyang/oozie/oozie-4.0.0-cdh5.2.0
这也也是即将配置环境变量的OOZIE_HOME
配置环境变量
向/etc/profile中加入如下三行，注意加完回到原用户后执行source /etc/profile
export OOZIE_HOME=/home/casliyang/oozie/oozie-4.0.0-cdh5.2.0
export OOZIE_CONFIG=$OOZIE_HOME/conf
export CLASSPATH=$CLASSPATH:$OOZIE_HOME/bin
将ext2.2.0和hadoop相关jar包加入war包，并发布到自带的web server下
在$OOZIE_HOME/bin目录下执行
./addtowar.sh -inputwar $OOZIE_HOME/oozie.war -outputwar $OOZIE_HOME/oozie-server/webapps/oozie.war -hadoop 2.5.0 $HADOOP_HOME -extjs /home/casliyang/Downloads/ext-2.2.zip
生成oozie数据库脚本并执行
这里使用的是自带的derby数据库
在$OOZIE_HOME/bin目录下
执行以下命令创建数据库脚本
./ooziedb.sh create -sqlfile oozie.sql
通过以下命令执行sql脚本初始化数据库
./oozie-setup.sh db create -run -sqlfile $OOZIE_HOME/bin/oozie.sql
配置oozie
配置$OOZIE_HOME/conf/oozie-site.xml
修改以下配置项，将值指向真实hadoop配置文件路径，实现oozie和hadoop的关联：
<property>
<name>oozie.service.HadoopAccessorService.hadoop.configurations</name>
<value>*=/home/casliyang/hadoop2/hadoop-2.5.0-cdh5.2.0/etc/hadoop</value>
<description>
Comma separated AUTHORITY=HADOOP_CONF_DIR, where AUTHORITY is the HOST:PORT of
the Hadoop service (JobTracker, HDFS). The wildcard ‘*‘ configuration is
used when there is no exact match for an authority. The HADOOP_CONF_DIR contains
the relevant Hadoop *-site.xml files. If the path is relative is looked within
the Oozie configuration directory; though the path can be absolute (i.e. to point
to Hadoop client conf/ directories in the local filesystem.
</description>
</property>
配置$OOZIE_HOME/conf/oozie-default.xml
将oozie.services属性中的org.apache.oozie.service.JobsConcurrencyService值提到第一个位置。
HDFS上创建共享目录
在$HADOOP_HOME/etc/hadoop/core-site.xml中加入以下配置，红色的casliyang为用户名，蓝色的casliyang为组名，singlehadoop为oozie的host（注意不能用localhost，会报错）：
<!-- for oozie,add by casliyang,2014-11-21 -->
<property>
<name>hadoop.proxyuser.casliyang.hosts</name>
<value>singlehadoop</value>
</property>
<property>
<name>hadoop.proxyuser.casliyang.groups</name>
<value>casliyang</value>
</property>
启动HADOOP，该步骤不详述。
在$OOZIE_HOME/bin目录下执行：
[email protected]:~/oozie/oozie-4.0.0-cdh5.2.0/bin$ ./oozie-setup.sh sharelib create -fs hdfs://singlehadoop:8020 -locallib $OOZIE_HOME/oozie-sharelib-4.0.0-cdh5.2.0-yarn.tar.gz
setting CATALINA_OPTS="$CATALINA_OPTS -Xmx1024m"

启动oozie
在$OOZIE_HOME/bin目录下
前台运行oozie：
./oozied.sh run
后台运行oozie：
./oozied.sh start
查看oozie网页：
停止oozie：
./oozied.sh stop
