linux下用rpm 安裝jdk

1.下載jdk的rpm安裝包，這裏以jdk-6u21-linux-i586-rpm.bin爲例進行說明

2. 將jdk-6u21-linux-i586-rpm.bin 移動到合適的安裝目錄上，安裝軟件不要在/home路徑下，這樣很容易涉及到不同用戶的訪問權限，這樣對程序的維護，是相當不利的。這裏將把安裝包移動到/opt目錄

mv jdk-6u21-linux-i586-rpm.bin /opt ;把安裝包移動到/opt目錄 cd /opt 

 

3. 給安裝包賦予運行權限

chmod 755 jdk-6u21-linux-i586-rpm.bin  

 

 

3. 安裝該rpm安裝包

4. 設置環境變量

[root@localhost opt]# vi /etc/profile ;編輯系統配置文件 ================================================================================== JAVA_HOME=/usr/java/jdk1.6.0_24/ ;增加以下幾行 CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar ;主要是配置路徑 PATH=$JAVA_HOME/bin:$PATH ; export JAVA_HOME,PATH,CLASSPATH ; :wq ;保存退出
