# Java 在linux当中配置解释器

<br>

```shell
[root@linux-node1 ~]# ls -l
total 177076
-rw-------. 1 root root      1589 Dec 28 07:50 anaconda-ks.cfg
-rw-r--r--  1 root root      1456 Dec 31 01:47 CentOS7.1-x86_644.cfg

[root@linux-node1 ~]# 
```

#### 解压 jdk-8u73-linux-x64.tar.gz 到指定的目录

```shell
[root@linux-node1 ~]# tar -xf jdk-8u73-linux-x64.tar.gz -C /usr/local
[root@linux-node1 ~]# cd /usr/local/
[root@linux-node1 local]# ls
bin  etc  games  include  jdk1.8.0_73  lib  lib64  libexec  python34  sbin  share  src
[root@linux-node1 local]# 
[root@linux-node1 local]# mv jdk1.8.0_73/ jdk
[root@linux-node1 local]# cd jdk/
[root@linux-node1 jdk]# cd bin/
[root@linux-node1 bin]# ls
appletviewer  extcheck  jar        java   javadoc         javah  javapackager  javaws  jconsole  jdb    jhat   jjs   jmc      jps         jsadebugd  jstat   jvisualvm  native2ascii  pack200     rmic  rmiregistry  serialver   tnameserv  wsgen     xjc

[root@linux-node1 bin]# ./java -version
java version "1.8.0_73"
Java(TM) SE Runtime Environment (build 1.8.0_73-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.73-b02, mixed mode)
```

<br>

#### 到这一步已经完成了解释器的解压,接下来再环境变量中进行添加设置

```shell
[root@linux-node1 local]# cd /etc/profile.d
[root@linux-node1 profile.d]# vim jdk.sh
#!/bin/bash
#

JAVA_HOME=/usr/local/jdk
JAVA_BIN=/usr/local/jdk/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME JAVA_BIN CLASSPATH PATH
[root@linux-node1 profile.d]# chmod +x jdk.sh 
[root@linux-node1 profile.d]# bash
[root@linux-node1 profile.d]# java -version
java version "1.8.0_73"
Java(TM) SE Runtime Environment (build 1.8.0_73-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.73-b02, mixed mode)
```

ok啦, 哈哈
