Linux服务器部署web项目

一.安装jdk

1.在/usr/目录下创建java目录
[root@localhost ~]# mkdir /usr/java
[root@localhost ~]# cd /usr/java
2.下载jdk,然后解压
[root@localhost java]# curl -O http://download.Oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.tar.gz
[root@localhost java]# tar -zxvf jdk-7u79-linux-x64.tar.gz
3.设置环境变量
[root@localhost java]# vi /etc/profile
在profile中添加如下内容:
#set java environment
JAVA_HOME=/usr/java/jdk1.7.0_79
JRE_HOME=/usr/java/jdk1.7.0_79/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME JRE_HOME CLASS_PATH PATH
让修改生效:
[root@localhost java]# source /etc/profile
4.验证JDK有效性
[root@localhost java]# java -version
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)
