- 1、 安装jdk1.6.0_26(安装java环境)
-
- Scp /etc/profile (注释)newnodeip:/etc
-
- 2、 安装hadoop及hbase、zookeeper
-
- Yum install hadoop-0.20
-
- Yum install hadoop-0.20-tasktarek
-
- Yum install hadoop-0.20-namenode
-
- Yum install hadoop-0.20-datanode
-
- Yum install hadoop-hbase
-
- 3|、从主节点拷贝配置文件到新加节点
-
- Scp –r /etc/hadoop-0.20/conf newnodeip:/etc/hadoop-0.20
-
- Scp –r /etc/hbase/conf newnodeip:/etc/hbase
-
- Scp –r /etc/zookeeper/conf newnodeip:/etc/zookeeper
-
- 3、 设置用户最大打开的文件数量:
-
- Vim /etc/security/limits.conf
-
- hdfs - nofile 32768
-
- hbase - nofile 32768
-
- 4、 在master主机上添加dns解析
-
- Vim /var/named/hdfs.zone
-
- $TTL 86400
-
- @ IN SOA hdfs. root(
-
- 200101111
-
- 14400
-
- 3600
-
- 604800
-
- 86400)
-
- master-hadoop IN A 192.168.5.249
-
- slave1-hadoop IN A 192.168.5.201
-
- hostname IN A newip(注释)
-
- master-hbase IN A 192.168.5.249
-
- slave1-hbase IN A 192.168.5.201
-
- hostname IN A newip(注释)
-
- @ IN NS ns.hdfs.
-
- /etc/rc.d/init.d/named restart
-
- 6,在本机设置dns
-
- vi /etc/resolv.conf
-
- earch hdfs
-
- domain hdfs
-
- nameserver 192.168.5.249
-
- nameserver 202.106.0.20
-
- ~
-
- 7、主节点master主机添加从节点配置:
-
- Vim /etc/hadoop-0.20/slaves
-
- slave1-hadoop.hdfs
-
- slave2-hadoop.hdfs
-
- slave4-hadoop.hdfs
-
- slave3-hadoop.hdfs
-
- hostname(注释)
-
- vim /etc/hbase/regionserver
-
- slave1-hadoop.hdfs
-
- slave2-hadoop.hdfs
-
- slave4-hadoop.hdfs
-
- slave3-hadoop.hdfs
-
- hostname(注释)
-
- 8、配置免密码验证
-
- Scp /home/hdfs/.ssh/* newip:/home/hdfs/.ssh
-
- 9、启动新加节点:
-
- /usr/hahadoop-0.20/bin/daemon start datanode
-
- /usr/hahadoop-0.20/bin/daemon start tasktracker
-
