java及tomcat环境配置

jdk环境搭建

[root@tyzz ~]# tar -zxvf jdk-8u91-linux-x64.tar.gz 
[root@tyzz ~]# mv jdk1.8.0_91/ /usr/local/jdk1.8
[root@tyzz ~]# ln -s /usr/local/jdk1.8/ /usr/local/jdk

[root@tyzz ~]# vim /etc/profile  
####################修改环境变量#############

vim /etc/profile.d/java.sh

---------------

JAVA_HOME=/usr/local/jdk1.8
JAVA_BIN=/usr/local/jdk1.8/bin
JRE_HOME=/usr/local/jdk1.8/jre
PATH=$PATH:/usr/local/jdk1.8/bin:/usr/local/jdk1.8/jre/bin
CLASSPATH=/usr/local/jdk1.8/jre/lib:/usr/local/jdk1.8/lib:/usr/local/jdk1.8/jre/lib/charsets.jar

-------------

根据自己的安装路径进行配置

. /etc/profile.d/java.sh 刷新生效
