Linux系統之下安裝配置JDK+TOMCAT

一:安裝JDK8

1. 登錄Linux

# honghe @ honghedeMacBook-Pro in ~ [13:52:45] 
$ ssh root@96.41.189.83 -p 29272    
root@96.41.189.83's password: 
[root@host ~]# ll
total 0
[root@host ~]# cd /
[root@host /]# ll
total 135258
dr-xr-xr-x.   2 root root      4096 Aug 10 22:01 bin
dr-xr-xr-x.   5 root root      1024 Mar 22  2017 boot
drwxr-xr-x   19 root root      3520 Aug 10 22:01 dev
drwxr-xr-x.  64 root root      4096 Aug 10 22:15 etc
drwxr-xr-x.   2 root root      4096 Sep 23  2011 home
dr-xr-xr-x.  15 root root     12288 Mar  7  2017 lib
drwx------.   2 root root     16384 Mar  7  2017 lost+found
dr-xr-x---.   3 root root      4096 Aug 10 22:18 root
drwxr-xr-x.  13 root root      4096 Aug 10 23:23 usr
drwxr-xr-x.  17 root root      4096 Mar  7  2017 var

2.建立java安裝目錄

cd /usr
mkdir java

3.本地下載jdk 複製到遠程/usr/java之下

根據linux系統下載相應的jdk版本
複製到遠程
# honghe @ honghedeMacBook-Pro in ~/Desktop [14:22:26] 
$ scp -P 29272 /Users/honghe/Desktop/jdk-8u181-linux-i586.tar.gz root@96.41.189.83:/usr/java
root@96.41.189.83's password: 
jdk-8u181-linux-i586.tar.gz                                                                      100%  180MB 201.9KB/s   15:12    

# honghe @ honghedeMacBook-Pro in ~/Desktop [14:38:50] 

4.解壓文件

[root@host java]# tar -zxvf jdk-8u181-linux-i586.tar.gz 

5.配置環境變量

vim /etc/profile
添加：
JAVA_HOME=/usr/java/jdk1.8.0_181
CLASSPATH=$JAVA_HOME/lib/
PATH=$PATH:$JAVA_HOME/bin
export PATH JAVA_HOME CLASSPATH

[root@host etc]# source /etc/profile
[root@host etc]# java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) Client VM (build 25.181-b13, mixed mode)
[root@host etc]# 

安裝成功。

二:安裝TOMCAT

1.下載上傳到遠程服務器

linux操作 :
[root@host /]# cd usr/
[root@host usr]# cd local/
[root@host local]# mkdir tomcat

mac操作：
# honghe @ honghedeMacBook-Pro in ~/Desktop [14:38:50] 
scp -P 29272 /Users/honghe/Desktop/apache-tomcat-8.5.32.tar.gz root@96.41.189.83:/usr/local/tomcat 

2.解壓啓動

[root@host tomcat]# tar -zxvf apache-tomcat-8.5.32.tar.gz 
[root@host tomcat]# ls
apache-tomcat-8.5.32  apache-tomcat-8.5.32.tar.gz
[root@host tomcat]# cd apache-tomcat-8.5.32
[root@host apache-tomcat-8.5.32]# ls
bin  conf  lib  LICENSE  logs  NOTICE  RELEASE-NOTES  RUNNING.txt  temp  webapps  work
[root@host apache-tomcat-8.5.32]# cd bin/
[root@host bin]# ./startup.sh
Using CATALINA_BASE:   //usr/local/tomcat/apache-tomcat-8.5.32
Using CATALINA_HOME:   //usr/local/tomcat/apache-tomcat-8.5.32
Using CATALINA_TMPDIR: //usr/local/tomcat/apache-tomcat-8.5.32/temp
Using JRE_HOME:        /usr/java/jdk1.8.0_181
Using CLASSPATH:       //usr/local/tomcat/apache-tomcat-8.5.32/bin/bootstrap.jar://usr/local/tomcat/apache-tomcat-8.5.32/bin/tomcat-juli.jar
Tomcat started.
