zookeeper配置以及/usr/profile的注意事项

source /etc/profile

JAVA_HOME="/usr/local/software/jdk1.7"

JRE_HOME="/usr/local/software/jdk1.7/jre"

ZOOKEEPER_HOME="/usr/local/software/zookeeper"

CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

PATH=$HADOOP_HOME/bin:$ZOOKEEPER_HOME/bin:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

export JAVA_HOME

export JRE_HOME

export ZOOKEEPER_HOME

export CLASSPATH

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC

server.0=192.168.7.70:2888:3888

server.1=192.168.7.101:2888:3888

server.2=192.168.7.109:2888:3888

cd zookeeper

mkdir data

vim myid

a 0 1 2

esc

shift:wq

cd:/usr/local

zkServer.sh start

注意在配置环境变量/usr/profile

1.JAVA_HOME="/usr/local/software/jdk1.7" 记得配置类似变量 + “”

2.

CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

PATH=$HADOOP_HOME/bin:$ZOOKEEPER_HOME/bin:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

以及

export CLASSPATH

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC

都应该放到最后，以便从上往下读取
