一、安装环境变量:

yum install gcc 

yum install gcc-c++

yum install make

yum install autoconfautomake libtool cmake

yum install ncurses-devel

yum install openssl-devel

yum install git git-svn git-email git-gui gitk

安装protoc(需用root用户)

1 tar -xvf protobuf-2.5.0.tar.bz2 

2 cd protobuf-2.5.0 

3 ./configure --prefix=/opt/protoc/ 

4 make && make install

安装wget

sudo yum -y install wget

 

 

二、增加用户组

groupadd hadoop  添加一个组

useradd hadoop -g hadoop  添加用户

 

 

三、编译hadoop

mvn clean package -Pdist,native -DskipTests -Dtar 

编译完的hadoop在 /home/hadoop/ocdc/hadoop-2.6.0-src/hadoop-dist/target 路径下

 

 

四、各节点配置hosts文件 vi/etc/hosts

10.1.245.244 master

10.1.245.243 slave1

10.1.245.242 slave2

命令行输入 hostname master

 

ssh到其他主机 相应输入 hostName xxxx

 

 

五、各节点免密码登录:

 

各节点 免密码登录

ssh-keygen -t rsa

cd /root/.ssh/

ssh-copy-id master

将生成的公钥id_rsa.pub 内容追加到authorized_keys(执行命令:cat id_rsa.pub >> authorized_keys)

 

时间等效性同步

ssh master date; ssh slave1 date;ssh slave2 date;

 

六、各节点hadoop路径下创建相应目录(namenode,datenode 等信息存放处)

Mkdir data

(在data路径下创建目录)

mkdir yarn

mkdir jn

mkdir current

(hadoop路径下)

mkdir name

 

(jn目录下)

mkdir streamcluster

 

 

七、Zookeeper配置:

Tar zxvf zookeeper-3.4.6.tar.gz

 

Cp zoo_sample.cfg zoo.cfg

 

修改zoo.cfg文件:

# The number of milliseconds of each tick

tickTime=2000

# The number of ticks that the initial

# synchronization phase can take

initLimit=10

# The number of ticks that can pass between

# sending a request and getting an acknowledgement

syncLimit=5

# the directory where the snapshot is stored.

# do not use /tmp for storage, /tmp here is just

# example sakes.

dataDir=/home/hadoop/ocdc/zookeeper-3.4.6/data

dataLogDir=/home/hadoop/ocdc/zookeeper-3.4.6/logs

# the port at which the clients will connect

clientPort=2183

# the maximum number of client connections.

# increase this if you need to handle more clients

#maxClientCnxns=60

#

# Be sure to read the maintenance section of the

# administrator guide before turning on autopurge.

#

# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance

#

# The number of snapshots to retain in dataDir

#autopurge.snapRetainCount=3

# Purge task interval in hours

# Set to "0" to disable auto purge feature

#autopurge.purgeInterval=1

 

server.1=master:2898:3898

server.2=slave1:2898:3898

server.3=slave2:2898:3898

 

在zookeeper目录下:

mkdir data

vi myid (写入id为1,)

拷贝zookeeper到各个目录下(将slave1中的myid改为2,slave2中的myid改为3....)

随后在 bin目录下 逐个启动zookeeper

./zkServer.sh start

./zkServer.sh status (查看状态)

 

 

八、hadoop相关配置文件配置

(需要注意的是在yarn-site.xml中

 

<property>

    <name>yarn.resourcemanager.ha.id</name>

    <value>rm1</value>

</property>

 

如果做HA 备用namenode服务器要修改为rm2)

 

 

mapred-site.xml

 

<configuration>

<property>

<name>mapreduce.framework.name</name>

   <value>yarn</value>

 </property>

 

<property>

  <name>mapreduce.jobhistory.address</name>

  <value>master:10020</value>

<property>

  <name>mapreduce.jobhistory.webapp.address</name>

  <value>master:19888</value>

 </property>

 

<property>

    <name>yarn.scheduler.maximum-allocation-mb</name>

    <value>16384</value>

  </property>

 

<property>

  <name>mapred.output.compression.type</name>

  <value>BLOCK</value>

</property>

</configuration>

 

 

slaves

vi slaves

 

master1

slave1

slave2

 

随后将拷贝配置好的hadoop到各个服务器中

 

 

九、启动Hadoop各组件

启动jounalnode

./hadoop-daemon.sh start journalnode

进行namenode格式化

./hadoop namenode -format 

 

 格式化后会在根据core-site.xml中的hadoop.tmp.dir配置生成个文件,之后通过下面命令,启动namenode进程在namenode2上执行

sbin/hadoop-daemon.sh start namenode

 

完成主备节点同步信息

./hdfs namenode –bootstrapStandby  

 

格式化ZK(在namenode1上执行即可, 这句命令必须手工打上,否则会报错)

./hdfs zkfc –formatZK

 

启动HDFS(在namenode1上执行)

./start-dfs.sh

 

启动YARN(在namenode1和namenode2上执行)

./start-yarn.sh

 

在namenode1上执行${HADOOP_HOME}/bin/yarn rmadmin -getServiceState rm1查看rm1和rm2分别为active和standby状态

 

 

我们在启动hadoop各个节点时,启动namenode和datanode,这个时候如果datanode的storageID不一样,那么会导致如下datanode注册不成功的信息:

这个时候,我们需要修改指定的datanode的current文件中的相应storageID的值,直接把它删除,这个时候,系统会动态新生成一个storageID,这样再次启动时就不会发生错误了。

查看端口是否占用

netstat -tunlp |grep 22

查看所有端口

netstat  -anplut

十、spark搭建

修改spark-env..sh 增加如下参数(路径根据服务器上的路径修改)

 

HADOOP_CONF_DIR=/home/hadoop/ocdc/hadoop-2.6.0/etc/hadoop/

HADOOP_HOME=/home/hadoop/ocdc/hadoop-2.6.0/

SPARK_HOME=/home/hadoop/ocdc/spark-1.6.1-bin-hadoop2.6/

SPARK_EXECUTOR_INSTANCES=3

SPARK_EXECUTOR_CORES=7

SPARK_EXECUTOR_MEMORY=11G

SPARK_DRIVER_MEMORY=11G

SPARK_YARN_APP_NAME="asiainfo.Spark-1.6.0"

#SPARK_YARN_QUEUE="default"

MASTER=yarn-cluster

 

 

修改spark-default.conf文件 (路径根据服务器上的路径修改)

 

spark.master yarn-client

spark.speculation        false

spark.sql.hive.convertMetastoreParquet  false

 

spark.driver.extraClassPath /home/hadoop/ocdc/spark-1.6.1-bin-hadoop2.6/lib/mysql-connector-java-5.1.30-bin.jar:/home/hadoop/ocdc/spark-1.6.1-bin-hadoop2.6/lib/datanucleus-api-jdo-3.2.6.jar:/home/hadoop/ocdc/spark-1.6.1-bin-hadoop2.6/lib

/datanucleus-core-3.2.10.jar:/home/hadoop/ocdc/spark-1.6.1-bin-hadoop2.6/lib/datanucleus-rdbms-3.2.9.jar:/home/hadoop/ocdc/spark-1.6.1-bin-hadoop2.6/lib/ojdbc14-10.2.0.3.jar
