Linux服务器安装JDK的步骤
Linux服务器安装JDK的步骤:
1.利用SSH工具上传下载好的JDK
cd D:\Program Files\SSH Communications Security\SSH Secure Shell
scp2.exe C:\Users\Administrator\Desktop\jdk-7u75-linux-x64.rpm [email protected]:/root
Are you sure you want to continue connecting (yes/no)? yes
[email protected]'s password:
2.在Linux端安装jdk
cd /root
chmod +x jdk-7u75-linux-x64.rpm
rpm -ivh jdk-7u75-linux-x64.rpm
3.配置环境变量,并验证是否安装成功
vi /etc/profile
JAVA_HOME=/usr/java/jdk1.7.0_75
CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME CLASSPATH PATH
编辑完成后记得输入:wq保存退出,最后一步就是通过source命令重新加载/etc/profile文件,使得修改后的内容在当前shell窗口有效:
source /etc/profile
java -version
javac -version
