Centos安装配置jdk 和tomcat

系统环境：centos6 / centos7

安装配置jdk

查询当前系统安装是否有jdk，有的话则卸载掉

rpm -qa|grep java
卸载： rpm -e  包名称   
加参数：--nodeps 忽略依赖关系卸载

百度网盘下载包（jdk 和tomcat ）：http://pan.baidu.com/s/1bpsgXUf

mkdir  -p /usr/local/java
tar xf jdk-7u49-linux-x64.gz -C /usr/local/java/
mv jdk1.7.0_79/ jdk1.7

修改系统环境变量

vim /etc/profile
添加下面内容到最下面，保存退出

export JAVA_HOME=/usr/local/java/jdk1.7
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/jre/lib/rt.jar

重新读取系统变量
source /etc/profile

查看java 设置系统变量是否生效

[root@localhost ~]# 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)

安装配置 tomcat

解压安装包，移动并更名

[root@localhost ~]# tar xf apache-tomcat-7.0.42.tar.gz 
[root@localhost ~]# mv apache-tomcat-7.0.42 /usr/local/java/tomcat

启动tomcat

[root@localhost ~]# /usr/local/java/tomcat/bin/startup.sh 
Using CATALINA_BASE:   /usr/local/java/tomcat
Using CATALINA_HOME:   /usr/local/java/tomcat
Using CATALINA_TMPDIR: /usr/local/java/tomcat/temp
Using JRE_HOME:        /usr/local/java/jdk1.7.0_79/jre
Using CLASSPATH:       /usr/local/java/tomcat/bin/bootstrap.jar:/usr/local/java/tomcat/bin/tomcat-juli.jar
