安装Tomcat、JDK（java）实验

1、安装JDK

上传jdk1.8到服务器，安装jdk

[root@java-tomcat1 ~]# tar xzf jdk-8u191-linux-x64.tar.gz -C /usr/local/
[root@java-tomcat1 ~]# cd /usr/local/
[root@java-tomcat1 local]# mv jdk1.8.0_191/ java

设置环境变量:

[root@java-tomcat1 local]# vim /etc/profile
JAVA_HOME=/usr/local/java #指定java安装目录
PATH=$JAVA_HOME/bin:$PATH #用于指定java系统查找命令的路径
export JAVA_HOME PATH #类的路径，在编译运行java程序时，如果有调用到其他类的时候，在classpath中寻找需要的类。

检测JDK是否安装成功:

[root@java-tomcat1 local]# source /etc/profile
[root@java-tomcat1 local]# java -version 
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

安装Tomcat

[root@java-tomcat1 ~]# mkdir /data/application -p
[root@java-tomcat1 ~]# cd /usr/src/
[root@java-tomcat1 src]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.42/bin/apache-tomcat-8.5.42.tar.gz
[root@java-tomcat1 src]# tar xzf apache-tomcat-8.5.42.tar.gz -C /data/application/
[root@java-tomcat1 src]# cd /data/application/
[root@java-tomcat1 application]# mv apache-tomcat-8.5.42/ tomcat

设置环境变量:

[root@java-tomcat1 application]# vim /etc/profile
export TOMCAT_HOME=/data/application/tomcat   #指定tomcat的安装目录
[root@java-tomcat1 application]# source  /etc/profile

查看tomcat是否安装成功:

[root@java-tomcat1 tomcat]# /data/application/tomcat/bin/startup.sh或 /data/application/tomcat/bin/version.sh
