CentOS 7 安装 Hadoop-cdh-2.5 on Mesos
CentOS 7 安装 Hadoop-cdh-2.5 on Mesos
1.环境说明
master 192.168.0.223 mesos-master
slave 192.168.0.225 mesos-salve
2.环境准备
关闭防火墙
关闭selinux
两台机器修改主机名master/slave
设置hosts，能互相解析
3.master和slave配置ssh互信
这里配置hadoop用户双机互信，因为hadoop用hadoop用户启动
master
yum -y install sshpass
ssh-keygen 一路回车
ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
slave
yum -y install sshpass
ssh-keygen 一路回车
ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
测试ssh对方主机，不提示输入密码则OK
4.安装JDK
tar zxvf jdk-8u65-linux-x64.tar.gz
mv jdk1.8.0_65 /usr/jdk
4.1设置环境变量
export JAVA_HOME=/usr/jdk
export JRE_HOME=/usr/jdk/jre
export CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib:$JRE_HOME/lib
export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
执行 source /etc/profile
4.2测试JDK
java -version #出现版本信息
5.安装mesos主从，看其他博客
安装完成，会在/usr/local/lib下生成一个libmesos.so文件
6.安装和配置Hadoop
master和slave
tar zxvf hadoop-2.5.0-cdh5.4.8.tar.gz
mv hadoop-2.5.0-cdh5.4.8 /usr/hadoop
cd /usr/hadoop
mkdir -p tmp
cd /usr/hadoop/
mv bin bin-mapreduce2/
ln -s bin-mapreduce1 bin
mv example example-mapreduce2
ln -s example-mapreduce1 example
cd etc/
mv hadoop hadoop-mapreduce2
ln -s hadoop-mapreduce1 hadoop
7.添加hadoop环境变量
vim /etc/profile
export HADOOP_HOME=/usr/hadoop
export PATH=$PATH:$HADOOP_HOME:$HADOOP_HOME/bin
source /etc/profile
8.获取hadoop on mesos的jar包
yum -y install maven openjdk-7-jdk git
git clone
cd hadoop
mvn package #获取jar包,jar包会在target下
9.把获取的jar包放到hadoop安装目录下
master和slave
cp hadoop/target/hadoop-mesos-0.1.0.jar /usr/hadoop/share/hadoop/common/lib/
10.配置hadoop on mesos
master和slave
vim /usr/hadoop/etc/hadoop/mapred.site.xml
<property>
<name>mapred.job.tracker</name>
<value>localhost:9001</value>
</property>
<property>
<name>mapred.jobtracker.taskScheduler</name>
<value>org.apache.hadoop.mapred.MesosScheduler</value>
</property>
<property>
<name>mapred.mesos.taskScheduler</name>
<value>org.apache.hadoop.mapred.JobQueueTaskScheduler</value>
</property>
<property>
<name>mapred.mesos.master</name>
<value>zk://192.168.0.223</value>
</property>
<property>
<name>mapred.mesos.executor.uri</name>
<value>hdfs://localhost:9000/hadoop-2.5.0-cdh5.2.0.tar.gz</value>
</property>
11.给hadoop用户权限
master和slave
chown -R hadoop:hadoop /usr/hadoop
12.在master上启动jobtracker，连接mesos
su hadoop
MESOS_NATIVE_LIBRARY=/usr/local/lib/libmesos.so hadoop jobtracker
13.测试
输入 192.168.0.223:5050 看看框架里有没有hadoop
