非HA的步骤:

一、部署设定
1.服务器
c1 192.168.100.105 zk、namenode、zkfc、datanode、nodemanager
c2 192.168.100.110 zk、namenode、zkfc、datanode、nodemanager、resourcemanager、journalnode
c3 192.168.100.115 zk、datanode、nodemanager、resourcemanager、journalnode
c4 192.168.100.120 zk、datanode、nodemanager、resourcemanager、journalnode
2.目录
hadoop namenode目录 /home/hadoop/hdfs/name
hadoop datanode目录 /home/hadoop/hdfs/data
hadoop临时目录 /home/hadoop/tmp
zookeeper数据目录 /home/zookeeper/data/
zookeeper日志目录 /home/zookeeper/logs/
二、系统配置
跟下面文章的第二点一样
https://www.cnblogs.com/live41/p/15467263.html
三、下载及配置环境变量
1.下载及解压
https://downloads.apache.org/hadoop/common/
http://zookeeper.apache.org/releases.html
解压到/home/目录
2.配置环境变量
vim ~/.bashrc
在末尾加入以下内容:
export HADOOP_HOME=/home/hadoop export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:/home/zookeeper/bin export HADOOP_COMMON_HOME=/home/hadoop export HADOOP_HDFS_HOME=/home/hadoop export HADOOP_MAPRED_HOME=/home/hadoop export HADOOP_CONF_DIR=/home/hadoop/etc/hadoop export HDFS_DATANODE_USER=root export HDFS_NAMENODE_USER=root export HDFS_SECONDARYNAMENODE_USER=root export YARN_HOME=/home/hadoop export YARN_RESOURCEMANAGER_USER=root export YARN_NODEMANAGER_USER=root
三、安装和配置ZooKeeper
1.创建data和logs目录
mkdir -pv /home/zookeeper/{data,logs}
2.编辑zoo.cfg
cd /home/zookeeper/conf cp zoo_sample.cfg zoo.cfg vim zoo.cfg
修改属性或添加内容:
tickTime=2000 initLimit=10 syncLimit=5 clientPort=2181 dataDir=/home/zookeeper/data/ dataLogDir=/home/zookeeper/logs server.1=c1:2888:3888 server.2=c2:2888:3888 server.3=c3:2888:3888 server.4=c4:2888:3888
