1、操作系统环境
Last login: Fri Feb 21 18:47:52 2014 from 192.168.56.1 [root@datacenter ~]# uname -a Linux datacenter.localdomain 2.6.39-200.24.1.el6uek.x86_64 #1 SMP Sat Jun 23 02:39:07 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux [root@datacenter ~]# more /etc/issue Oracle Linux Server release 6.3 Kernel \r on an \m [root@datacenter ~]#
2、上传JDK安装包
[root@datacenter ~]# ll total 67296 -rw-------. 1 root root 1548 Feb 17 17:02 anaconda-ks.cfg drwxr-xr-x 2 root root 4096 Feb 21 18:37 bea -rw-r--r--. 1 root root 30877 Feb 17 17:02 install.log -rw-r--r--. 1 root root 9389 Feb 17 17:00 install.log.syslog -rw-r--r-- 1 root root 68852176 Feb 20 22:30 jdk-6u38-ea-bin-b04-linux-amd64-31_oct_2012-rpm.bin
3、创建JDK安装目录
[root@datacenter ~]# mkdir -p /opt/jdk [root@datacenter ~]# mv jdk-6u38-ea-bin-b04-linux-amd64-31_oct_2012-rpm.bin /opt/jdk/
4、移除以前的JDK
[root@datacenter ~]# rpm -qa | grep jdk java-1.6.0-openjdk-1.6.0.0-1.45.1.11.1.el6.x86_64 [root@datacenter ~]# yum remove java-1.6.0-openjdk-1.6.0.0-1.45.1.11.1.el6.x86_64 Loaded plugins: security Setting up Remove Process Resolving Dependencies --> Running transaction check ---> Package java-1.6.0-openjdk.x86_64 1:1.6.0.0-1.45.1.11.1.el6 will be erased --> Finished Dependency Resolution Dependencies Resolved ============================================================================================================================================== Package Arch Version Repository Size ============================================================================================================================================== Removing: java-1.6.0-openjdk x86_64 1:1.6.0.0-1.45.1.11.1.el6 @anaconda-OracleLinuxServer-201206261930.x86_64/6.3 81 M Transaction Summary ============================================================================================================================================== Remove 1 Package(s) Installed size: 81 M Is this ok [y/N]: y Downloading Packages: Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Erasing : 1:java-1.6.0-openjdk-1.6.0.0-1.45.1.11.1.el6.x86_64 1/1 Verifying : 1:java-1.6.0-openjdk-1.6.0.0-1.45.1.11.1.el6.x86_64 1/1 Removed: java-1.6.0-openjdk.x86_64 1:1.6.0.0-1.45.1.11.1.el6 Complete!
5、安装JDK
[root@datacenter ~]# cd /opt/jdk/ [root@datacenter jdk]# ll total 67240 -rw-r--r-- 1 root root 68852176 Feb 20 22:30 jdk-6u38-ea-bin-b04-linux-amd64-31_oct_2012-rpm.bin [root@datacenter jdk]# chmod +x jdk-6u38-ea-bin-b04-linux-amd64-31_oct_2012-rpm.bin [root@datacenter jdk]# ll total 67240 -rwxr-xr-x 1 root root 68852176 Feb 20 22:30 jdk-6u38-ea-bin-b04-linux-amd64-31_oct_2012-rpm.bin [root@datacenter jdk]# ./jdk-6u38-ea-bin-b04-linux-amd64-31_oct_2012-rpm.bin Unpacking...

6、配置/etc/profile环境变量,(新增加红色字体部分).
[root@datacenter jdk]# vi /etc/profile # /etc/profile # System wide environment and startup programs, for login setup # Functions and aliases go in /etc/bashrc # It's NOT a good idea to change this file unless you know what you # are doing. It's much better to create a custom.sh shell script in # /etc/profile.d/ to make custom changes to your environment, as this # will prevent the need for merging in future 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 [ "$HISTCONTROL" = "ignorespace" ] ; then export HISTCONTROL=ignoreboth else export HISTCONTROL=ignoredups fi export JAVA_HOME=/usr/java/jdk1.6.0_38/ export JAVA_BIN=/usr/java/jdk1.6.0_38/bin/ export PATH=$PATH:$JAVA_HOME/bin export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export JAVA_HOME JAVA_BIN CLASSPATH export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL # By default, we want umask to get set.

7、验证JDK安装
[root@datacenter jdk]# java Usage: java [-options] class [args...] (to execute a class) or java [-options] -jar jarfile [args...] (to execute a jar file) where options include: -d32 use a 32-bit data model if available -d64 use a 64-bit data model if available -server to select the "server" VM The default VM is server. -cp <class search path of directories and zip/jar files> -classpath <class search path of directories and zip/jar files> A : separated list of directories, JAR archives, and ZIP archives to search for class files. -D<name>=<value> set a system property -verbose[:class|gc|jni] enable verbose output -version print product version and exit -version:<value> require the specified version to run -showversion print product version and continue -jre-restrict-search | -jre-no-restrict-search include/exclude user private JREs in the version search -? -help print this help message -X print help on non-standard options -ea[:<packagename>...|:<classname>] -enableassertions[:<packagename>...|:<classname>] enable assertions -da[:<packagename>...|:<classname>] -disableassertions[:<packagename>...|:<classname>] disable assertions -esa | -enablesystemassertions enable system assertions -dsa | -disablesystemassertions disable system assertions -agentlib:<libname>[=<options>] load native agent library <libname>, e.g. -agentlib:hprof see also, -agentlib:jdwp=help and -agentlib:hprof=help -agentpath:<pathname>[=<options>] load native agent library by full pathname -javaagent:<jarpath>[=<options>] load Java programming language agent, see java.lang.instrument -splash:<imagepath> show splash screen with specified image
