linux下安装jdk和tomcat

Linux下安装JDK和tomcat

首先把JDK和tomcat的安装文件copy到linux usr/local文件夹中

jdk安装文件名为:jdk-6u3-linux-i586-rpm.bin

tomcat的安装包为:apache-tomcat-6.0.14.tar.gz

安装JDK

使用 ./ 执行 jdk-6u3-linux-i586-rpm.bin文件:./jdk*

然后在接下来选择同意安装协议

JDK会进行解压缩,解压缩完成后在目录下会看到一些rpm文件,如下

[root@localhost local]# ls
apache-tomcat-6.0.14.tar.gz  sbin
bin                         	 	share
etc                          		src
games                        		sun-javadb-client-10.2.2-0.1.i386.rpm
include                      		sun-javadb-common-10.2.2-0.1.i386.rpm
jdk-6u3-linux-i586.rpm       	sun-javadb-core-10.2.2-0.1.i386.rpm
jdk-6u3-linux-i586-rpm.bin   	sun-javadb-demo-10.2.2-0.1.i386.rpm
lib                          		sun-javadb-docs-10.2.2-0.1.i386.rpm
libexec                      		sun-javadb-javadoc-10.2.2-0.1.i386.rpm
 

安装jdk*.rpm文件:rpm -ivh jdk*.rpm

[root@localhost local]# rpm -ivh jdk*.rpm
Preparing...                ########################################### [100%]
	 package jdk-1.6.0_03-fcs.i586 is already installed
 

安装完成之后,我们在usr中可以看到生成了一个java文件夹

[root@localhost usr]# ls
bin  etc  games  include  java  kerberos  lib  lib64  libexec  local  sbin  share  src  tmp  X11R6
 

配置环境变量

查看环境变量:echo $PATH

设置环境变量

打开文件:vi /etc/profile  

设置变量:

JAVA_HOME=/usr/java/jdk1.6.0
CLASSPATH=$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:./
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME CLASSPATH PATH
 

执行文件:source /etc/profile

查看JDK安装是否成功:

java -version 
javac -version
 

安装Tomcat

在usr/local目录下直接解压缩apache-tomcat-6.0.14.tar.gz

tar zxvf apache-tomcat-6.0.14.tar.gz
 

然后在该目录下就能看到生成了一个文件夹

[root@localhost local]# ls
apache-tomcat-6.0.14  apache-tomcat-6.0.14.tar.gz  bin  etc  games  include  lib  libexec  sbin  share  src
 

设置一个软链接:

[root@localhost local]# ln -sf /usr/local/apache-tomcat-6.0.14 /usr/local/tomcat
 

再次查看该目录,就会发现该目录下重新生成了一个tomcat的文件夹

[root@localhost local]# ls
apache-tomcat-6.0.14  apache-tomcat-6.0.14.tar.gz  bin  etc  games  include  lib  libexec  sbin  share  src  tomcat
 

设置环境变量:

CATALINA_HOME=/usr/local/tomcat
JAVA_HOME=/usr/java/jdk1.6.0
CLASSPATH=$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$CATALINA_HOME/lib/servlet-api.jar:./
PATH=$JAVA_HOME/bin:$PATH
export CATALINA_HOME JAVA_HOME CLASSPATH PATH
 

启动tomcat:

[root@localhost tomcat]# bin/startup.sh
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:       /usr/java/jdk1.6.0
 

停止tomcat:

[root@localhost tomcat]# bin/shutdown.sh
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:       /usr/java/jdk1.6.0
