rehl6.3下配置JDK1.7

公司上泛微OA，要求配置resin，需要首先配置Java环境，我在配置过程中进行了整理，希望可以帮到跟我一样情况的同学。

一：环境要求

1、OS ： rehl 6.3

2、Java环境： JDK1.7.0_79

 

二、Java环境安装

1、下载JDK1.7，并放置到 Linux下的/mnt目录中，只是临时放置，位置自己定。

2、创建目录 /usr/java

   [root@fanweiwebjdk1.7.0_79]# mkdir /usr/java

3、将/mnt下的JDK1.7 移动到/usr/java下

   [root@fanweiwebmnt]# mv jdk1.7.0_79/ /usr/java/

4、查看是否正确移动

   [root@fanweiwebmnt]# cd /usr/java/

   [root@fanweiwebjava]# ls

   jdk1.7.0_79

   [root@fanweiweb java]# cd jdk1.7.0_79/

   [root@fanweiwebjdk1.7.0_79]# ls

   bin  COPYRIGHT db  include  jre lib  LICENSE  man README.html  release     src.zip  THIRDPARTYLICENSEREADME-JAVAFX.txt  THIRDPARTYLICENSEREADME.txt

5、配置/etc/profile文件，在文件以下位置追加如下内容：（根据JDK实际放置路径位置，以下是我的路径）

   exportJAVA_HOME=/usr/java/jdk1.7.0_79

   exportJRE_HOME=/usr/java/jdk1.7.0_79/jre

   exportPATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

   exportCLASSPATH=/usr/java/jdk1.7.0_79/lib

 

   以下打黄色的位置：

   [root@fanweiweb~]# vi /etc/profile

 

# /etc/profile

 

# System wide environment and startupprograms, for login setup

# Functions and aliases go in /etc/bashrc

 

# It's NOT a good idea to change this fileunless you know what you

# are doing. It's much better to create acustom.sh shell script in

# /etc/profile.d/ to make custom changes toyour environment, as this

# will prevent the need for merging infuture updates.

 

pathmunge () {

   case ":${PATH}:" in

       *:"$1":*)

           ;;

       *)

           if [ "$2" = "after" ] ; then

                PATH=$PATH:$1

           else

                PATH=$1:$PATH

           fi

   esac

}

 

 

if [ -x /usr/bin/id ]; then

   if [ -z "$EUID" ]; then

       # ksh workaround

       EUID=`id -u`

       UID=`id -ru`

   fi

   USER="`id -un`"

   LOGNAME=$USER

   MAIL="/var/spool/mail/$USER"

fi

 

# Path manipulation

if [ "$EUID" = "0" ];then

   pathmunge /sbin

   pathmunge /usr/sbin

   pathmunge /usr/local/sbin

else

   pathmunge /usr/local/sbin after

   pathmunge /usr/sbin after

   pathmunge /sbin after

fi

 

HOSTNAME=`/bin/hostname 2>/dev/null`

HISTSIZE=1000

if [ "$HISTCONTROL" ="ignorespace" ] ; then

   export HISTCONTROL=ignoreboth

else

   export HISTCONTROL=ignoredups

fi

 

 

#########################  jdk1.7.0  #############################

 

export JAVA_HOME=/usr/java/jdk1.7.0_79

export JRE_HOME=/usr/java/jdk1.7.0_79/jre

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

export CLASSPATH=/usr/java/jdk1.7.0_79/lib

# By default, we want umask to get set.This sets it for login shell

# Current threshold for system reserveduid/gids is 200

# You could check uidgid reservationvalidity in

# /usr/share/doc/setup-*/uidgid file

if [ $UID -gt 199 ] && [ "`id-gn`" = "`id -un`" ]; then

   umask 002

else

   umask 022

fi

 

for i in /etc/profile.d/*.sh ; do

   if [ -r "$i" ]; then

       if [ "${-#*i}" != "$-" ]; then

           . "$i"

       else

           . "$i" >/dev/null 2>&1

       fi

   fi

done

 

unset i

unset pathmunge

 

6、不需要重启，直接读取/etc/profile文件

   [root@fanweiwebjdk1.7.0_79]# source /etc/profile

7、检查刚才配置的Java环境变量

   [root@fanweiweb~]# echo $JAVA_HOME

   /usr/java/jdk1.7.0_79

   [root@fanweiweb~]# echo $PATH

/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/java/jdk1.7.0_79/bin:/usr/java/jdk1.7.0_79/jre/bin:/root/bin

   [root@fanweiweb~]# echo $CLASSPATH

   /usr/java/jdk1.7.0_79/lib

   [root@fanweiweb~]# echo $JRE_HOME

   /usr/java/jdk1.7.0_79/jre

8、检查Java是否安装成功，检查版本即可

   [root@fanweiweb~]# java -version

   javaversion "1.7.0_79"

   Java(TM)SE Runtime Environment (build 1.7.0_79-b15)

   JavaHotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

   [root@fanweiweb~]#

到此，Java配置成功。
