cdh 6.2.1部署

作者：互联网

环境准备

此次部署为5台服务器，hadoop1有公网，其他均为内网

角色划分方面，由于演示集群的总节点数很少，不可避免有大量角色合设。最终分配方案如下（CM：Cloudera Manager；NN：NameNode；RM：ResourceManager；ZK： ZooKeeper；SNN：SecondaryNameNode；HS2：HiveServer2；DN：DataNode；NM： NodeManager；M：HBase Master；RS：RegionServer）：

hadoop1（2核8G）：CM、NN、RM、Hue   hadoop2：SNN、HS2、M   hadoop3：DN、NM、ZK、RS   hadoop4：DN、NM、ZK、RS   hadoop5：DN、NM、ZK、RS 
 vim /etc/hosts
 192.168.0.206   hadoop1
 192.168.0.209   hadoop2
 192.168.0.208   hadoop3
 192.168.0.210   hadoop4
 192.168.0.207   hadoop5
 vim /etc/rc.d/rc.local
 # 最下面添加以下代码
 if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
 echo never > /sys/kernel/mm/transparent_hugepage/enabled
 fi
 if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
 echo never > /sys/kernel/mm/transparent_hugepage/defrag
 fi
 ​
 chmod +x /etc/rc.d/rc.local
 ​
 重启服务器reboot 生效配置
 上传 jdk-mysql-connector 我放在root下了 内包含jdk-8u181-linux-x64.rpm   mysql-connector-java-5.1.41-bin.jar
 scp -r jdk-mysql-connector/ hadoop2:`pwd`
 ​
 # 进入目录
 cd /root/jdk-mysql-connector/
 ​
 # 安装rpm包
 yum -y install *.rpm 
 ​
 #配置环境变量
 cd ~
 vi .bash_profile
 ​
 # 增加一行
 export JAVA_HOME=/usr
 cd ~
 source .bash_profile
 ​
 # 查看JDK版本信息
 java -version
 ​
 # 把jar包创建软连接
 ​
 mkdir -p /usr/share/java/
 cd ~/jdk-mysql-connector
 cp mysql-connector-java-5.1.41-bin.jar /usr/share/java/
 cd /usr/share/java/
 ln -s mysql-connector-java-5.1.41-bin.jar mysql-connector-java.jar

单机hadoop1部署 只在hadoop1配即可
