不多说，直接上干货！
我的机器情况是，bigdatamaster（Oozie是安装在这台节点上）、bigdataslave1和bigdatalsave2。
启动步骤
第一：先启动mysqld服务进程
因为，我的mysql是安装在/home/hadoop，在root用户下执行安装的。（当然，你也可以设置为开机启动）
[root@bigdatamaster hadoop]# service mysqld start
Starting mysqld: [ OK ]
[root@bigdatamaster hadoop]#
第二 :开启hadoop集群，是因为需要oozie，需要用到fs
[hadoop@bigdatamaster oozie-4.1.0-cdh5.5.4]$ jps 8920 NameNode 9077 SecondaryNameNode 11133 Jps 2182 QuorumPeerMain 9270 ResourceManager [hadoop@bigdatamaster oozie-4.1.0-cdh5.5.4]$
第三步：开启oozie进程
[hadoop@bigdatamaster oozie-4.1.0-cdh5.5.4]$ bin/oozie-start.sh 或者 [hadoop@bigdatamaster oozie-4.1.0-cdh5.5.4]$ bin/oozied.sh start
[hadoop@bigdatamaster oozie-4.1.0-cdh5.5.4]$ pwd /home/hadoop/app/oozie-4.1.0-cdh5.5.4 [hadoop@bigdatamaster oozie-4.1.0-cdh5.5.4]$ ll total 1014200 drwxr-xr-x 2 hadoop hadoop 4096 Apr 26 2016 bin drwxr-xr-x 4 hadoop hadoop 4096 Apr 26 2016 conf drwxrwxr-x 3 hadoop hadoop 4096 May 9 14:42 data drwxr-xr-x 6 hadoop hadoop 4096 Apr 26 2016 docs drwxr-xr-x 2 hadoop hadoop 4096 May 9 10:50 lib drwxrwxr-x 3 hadoop hadoop 4096 May 9 10:09 libext drwxr-xr-x 2 hadoop hadoop 12288 Apr 26 2016 libtools -rw-r--r-- 1 hadoop hadoop 37664 Apr 26 2016 LICENSE.txt drwxrwxr-x 2 hadoop hadoop 4096 May 9 16:00 logs -rw-r--r-- 1 hadoop hadoop 909 Apr 26 2016 NOTICE.txt drwxrwxr-x 3 hadoop hadoop 4096 May 8 15:59 oozie-4.1.0-cdh5.5.4 drwxr-xr-x 2 hadoop hadoop 4096 Apr 26 2016 oozie-core -rwxr-xr-x 1 hadoop hadoop 46275 Apr 26 2016 oozie-examples.tar.gz -rwxr-xr-x 1 hadoop hadoop 77456039 Apr 26 2016 oozie-hadooplibs-4.1.0-cdh5.5.4.tar.gz drwxrwxrwx 9 hadoop hadoop 4096 Apr 26 2016 oozie-server -r--r--r-- 1 hadoop hadoop 428704179 Apr 26 2016 oozie-sharelib-4.1.0-cdh5.5.4.tar.gz -r--r--r-- 1 hadoop hadoop 429103879 Apr 26 2016 oozie-sharelib-4.1.0-cdh5.5.4-yarn.tar.gz -rw-rw-r-- 1 hadoop hadoop 7620 May 8 20:38 oozie.sql -rwxr-xr-x 1 hadoop hadoop 103020321 Apr 26 2016 oozie.war -rw-r--r-- 1 hadoop hadoop 83521 Apr 26 2016 release-log.txt drwxr-xr-x 21 hadoop hadoop 4096 Apr 26 2016 src [hadoop@bigdatamaster oozie-4.1.0-cdh5.5.4]$ bin/oozie-start.sh WARN: Use of this script is deprecated; use 'oozied.sh start' instead Setting OOZIE_HOME: /home/hadoop/app/oozie-4.1.0-cdh5.5.4 Setting OOZIE_CONFIG: /home/hadoop/app/oozie-4.1.0-cdh5.5.4/conf Sourcing: /home/hadoop/app/oozie-4.1.0-cdh5.5.4/conf/oozie-env.sh setting CATALINA_OPTS="$CATALINA_OPTS -Xmx1024m" setting OOZIE_CONF=${OOZIE_HOME}/conf setting OOZIE_DATA=${OOZIE_HOME}/data setting OOZIE_LOG=${OOZIE_HOME}/logs setting CATALINA_BASE=${OOZIE_HOME}/oozie-server setting CATALINA_TMPDIR=${OOZIE_HOME}/oozie-server/temp setting CATALINA_OUT=${OOZIE_LOG}/catalina.out Setting OOZIE_CONFIG_FILE: oozie-site.xml Using OOZIE_DATA: /home/hadoop/app/oozie-4.1.0-cdh5.5.4/data Using OOZIE_LOG: /home/hadoop/app/oozie-4.1.0-cdh5.5.4/logs Setting OOZIE_LOG4J_FILE: oozie-log4j.properties Setting OOZIE_LOG4J_RELOAD: 10 Setting OOZIE_HTTP_HOSTNAME: bigdatamaster Setting OOZIE_HTTP_PORT: 11000 Setting OOZIE_ADMIN_PORT: 11001 Setting OOZIE_HTTPS_PORT: 11443 Setting OOZIE_BASE_URL: http://bigdatamaster:11000/oozie Using CATALINA_BASE: /home/hadoop/app/oozie-4.1.0-cdh5.5.4/oozie-server Setting OOZIE_HTTPS_KEYSTORE_FILE: /home/hadoop/.keystore Setting OOZIE_HTTPS_KEYSTORE_PASS: password Setting OOZIE_INSTANCE_ID: bigdatamaster Using CATALINA_OUT: /home/hadoop/app/oozie-4.1.0-cdh5.5.4/logs/catalina.out Setting CATALINA_PID: /home/hadoop/app/oozie-4.1.0-cdh5.5.4/oozie-server/temp/oozie.pid Using CATALINA_OPTS: -Xmx1024m -Dderby.stream.error.file=/home/hadoop/app/oozie-4.1.0-cdh5.5.4/logs/derby.log Adding to CATALINA_OPTS: -Doozie.home.dir=/home/hadoop/app/oozie-4.1.0-cdh5.5.4 -Doozie.config.dir=/home/hadoop/app/oozie-4.1.0-cdh5.5.4/conf -Doozie.log.dir=/home/hadoop/app/oozie-4.1.0-cdh5.5.4/logs -Doozie.data.dir=/home/hadoop/app/oozie-4.1.0-cdh5.5.4/data -Doozie.instance.id=bigdatamaster -Doozie.config.file=oozie-site.xml -Doozie.log4j.file=oozie-log4j.properties -Doozi e.log4j.reload=10 -Doozie.http.hostname=bigdatamaster -Doozie.admin.port=11001 -Doozie.http.port=11000 -Doozie.https.port=11443 -Doozie.base.url=http://bigdatamaster:11000/oozie -Doozie.https.keystore.file=/home/hadoop/.keystore -Doozie.https.keystore.pass=password -Djava.library.path= Using CATALINA_BASE: /home/hadoop/app/oozie-4.1.0-cdh5.5.4/oozie-server Using CATALINA_HOME: /home/hadoop/app/oozie-4.1.0-cdh5.5.4/oozie-server Using CATALINA_TMPDIR: /home/hadoop/app/oozie-4.1.0-cdh5.5.4/oozie-server/temp Using JRE_HOME: /home/hadoop/app/jdk Using CLASSPATH: /home/hadoop/app/oozie-4.1.0-cdh5.5.4/oozie-server/bin/bootstrap.jar Using CATALINA_PID: /home/hadoop/app/oozie-4.1.0-cdh5.5.4/oozie-server/temp/oozie.pid [hadoop@bigdatamaster oozie-4.1.0-cdh5.5.4]$
第四步：查看oozie启动日志，是否会报错
[hadoop@bigdatamaster logs]$ tail -n 100 oozie.log
第五步：查看oozie进程
[hadoop@bigdatamaster oozie-4.1.0-cdh5.5.4]$ jps 8920 NameNode 9077 SecondaryNameNode 11314 Jps 11185 Bootstrap 2182 QuorumPeerMain 9270 ResourceManager [hadoop@bigdatamaster oozie-4.1.0-cdh5.5.4]$
第六步：查看oozie web ui界面
http://bigdatamaster:11000/oozie/
成功！
