[环境变量]--环境变量配置汇总(windows和linux)

一、linux 或者 mac 下环境变量

java、maven、scala、zookeeper、hadoop单节点

PATH=$PATH:$HOME/bin
export JAVA_HOME=/usr/java/jdk1.7.0_79
export PATH=$PATH:$JAVA_HOME/bin
export SCALA_HOME=/opt/scala/scala-2.11.8
export PATH=$SCALA_HOME/bin:$PATH
export ZOOKEEPER_HOME=/opt/zookeeper/zookeeper-3.4.6
export PATH=$ZOOKEEPER_HOME/bin:$PATH
export MAVEN_HOME=/opt/maven/apache-maven-3.3.9
export PATH=$MAVEN_HOME/bin:$PATH
export HADOOP_HOME=/opt/hadoop-2.6.0
export PATH=$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"
export PATH=HADOOP_OPTS:$PATH
export PATH

二、windows下环境变量

1、java、scala、maven、hadoop环境变量

//注意：hadoop和spark的环境变量最好都放在系统变量中，否则可能会失败
JAVA_HOME=C:\Program Files\Java\jdk1.7.0_79
SCALA_HOME=C:\Program Files (x86)\scala
HADOOP_HOME=D:\hadoop-2.6.0
SPARK_HOME=D:\spark-1.6.2-bin-hadoop2.6
MAVEN_HOME=C:\kuibu\soft\maven3.3.9
CLASSPATH=.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar.;%SCALA_HOME%\bin;%SCALA_HOME%\lib\dt.jar;%SCALA_HOME%\lib\tools.jar.;
Path=C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon\;C:\kuibu\soft\svn_client\bin;D:\hadoop-2.6.0\bin;%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;%MAVEN_HOME%\bin;C:\Program Files (x86)\scala\bin;%SCALA_HOME%\bin;%SCALA_HOME%\jre\bin

注意：

(1)修改hadoop目录下的文件

D:\hadoop-2.6.0\etc\hadoop\hadoop-env.cmd

修改jdk的路径：

set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_67

(2)在配置hadoop环境变量时，需要在hadoop的bin目录下添加如下文件：

2、scala配置参考
