一、下载jdk

jdk-8u101-linux-x64.tar.gz

二、解压 创建好java_home目录

tar -zxvf jdk-8u101-linux-x64.tar.gz

jdk1.8.0_101

 

mkdir -p /usr/local/java/

mv jdk1.8.0_101 /usr/local/java/

 

三、环境变量设置、验证

vim /etc/profile

 

PATH=$PATH:$HOME/bin

export JAVA_HOME=/usr/local/java/jdk1.8.0_101

export JAVA_BIN=JAVA_HOME/bin

export PATH=$PATH:$JAVA_HOME/bin

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export JAVA_HOME JAVA_BIN PATH CLASSPATH

 

wq!保存

 

 

java

 

javac

 

java -version

 

还可以 yy

export JAVA_HOME="xxx"

export PATH="$PATH:$JAVA_HOME/bin"

export JRE_HOME="$JAVA_HOME/jre"

export CLASSPATH=".:$JAVA_HOME/lib:$JRE_HOME/lib"

 

#举例如下：

# mysql

export PATH=/usr/local/mysql/bin:$PATH

# mongodb

export PATH=/usr/local/mongodb/bin:$PATH

# memcached

export PATH=/usr/local/memcached/bin:$PATH

# redis

export PATH=/usr/local/redis/bin:$PATH

# hadoop

export PATH=/usr/local/hadoop/bin:$PATH
