本文詳細講解Linux系統(tǒng)下JDK、Tomcat的安裝

Jdk安裝：

[root@b home]# ls

jdk-1_5_0_12-linux-i586-rpm.bin lost found oracle

1、將jdk進行解壓

[root@b home]# ./jdk-1_5_0_12-linux-i586-rpm.bin

2、將解壓文件copy到/usr/java下

[root@b home]# cp jdk-1_5_0_12-linux-i586.rpm /usr/java

[root@b home]# cd /usr/java

3、進行安裝

[root@b java]# rpm -ivh jdk-1_5_0_12-linux-i586.rpm

Preparing... (########################################### [100%]

package jdk-1.5.0_12-fcs is already installed

4、將環(huán)境變量加入到profile中，如果寫入到(/etc/profile)對所有用戶都生效，如果只對某個用戶生效寫入到(/home/username/profile)中

export JAVA_HOME = /usr/java/jdk1.5

export PATH = $PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin

exportCLASSPATH=.:/usr/java/jdk1.5/lib:/usr/java/jdk1.5/jre/lib:$CLASSPATH

5、驗證安裝結果

[root@b java]# java -version

-bash: java: command not found

錯誤原因是環(huán)境變量未生效。

[root@b java]# source /etc/profile

[root@b java]# java -version

java version "1.5.0_12"

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_12-b04)

Java HotSpot(TM) Client VM (build 1.5.0_12-b04, mixed mode, sharing)

至此安裝成功。

Tomcat安裝：

1、將文件copy到/usr/local下解壓安裝文件

[root@b local]# tar -zxvf apache-tomcat-5.5.23.tar.gz

[root@b local]# ls

apache-tomcat-5.5.23 bin games lib man share

apache-tomcat-5.5.23.tar.gz etc include libexec sbin src

[root@b local]# cd ~

2、加入環(huán)境變量

[root@b root]# vi .bashrc

export JAVA_HOME=/usr/java/jdk1.5.0_12

export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOMR/bin

export CATALINA_BASE=/usr/local/apache-tomcat-5.5.23

export CATALINA_HOME=/usr/local/apache-tomcat-5.5.23

3、使環(huán)境變量生效

[root@b root]# source .bashrc

4、驗證安裝結果

[root@b root]# echo $JAVA_HOME

/usr/java/jdk1.5.0_12

[root@b root]# echo $CATALINA_HOME

/usr/local/apache-tomcat-5.5.23

[root@b root]#
