CENT-OS安装jdk1.6和Tomcat

1.》分别下载JDK1.6包和Tomcat包如：jdk-6u25-linux-x64.bin和apache-tomcat-6.0.33.tar.gz

2》.安装JD

1. 以root身份登录系统

 

2.转到文件夹/usr下，cd /usr。新建文件夹java mkdir java，安装文件用samba拷贝到/usr/java下：

 

3.通过chmod ＋x jdk-6u7-linux-i586.bin命令使其获得可执行权限

 

4.通过 ./jdk-6u7-linux-i586.bin来进行安装

 

5.安装完毕,JDK安装在/usr/java/目录下

 

6.设置环境变量(写入/etc/profile中)

vi /etc/profile

文件修改如下，红色字部分为需要修改部分

 

# /etc/profile
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc
pathmunge () {
        if ! echo $PATH | /bin/egrep -q "(^|:)$1($|:)" ; then
           if [ "$2" = "after" ] ; then
              PATH=$PATH:$1
           else
              PATH=$1:$PATH
           fi
        fi
}
# Path manipulation
#if [ `id -u` = 0 ]; then
        pathmunge /sbin
        pathmunge /usr/sbin
        pathmunge /usr/local/sbin
#fi
pathmunge /usr/X11R6/bin after
unset pathmunge
# No core files by default
ulimit -S -c 0 > /dev/null 2>&1

USER="`id -un`"
LOGNAME=$USER
MAIL="/var/spool/mail/$USER"

HOSTNAME=`/bin/hostname`
HISTSIZE=1000

if [ -z "$INPUTRC" -a ! -f "$HOME/.inputrc" ]; then
    INPUTRC=/etc/inputrc
fi

JAVA_HOME=/usr/java/jdk1.6.0_07

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

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

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC JAVA_HOME CLASSPATH

for i in /etc/profile.d/*.sh ; do
    if [ -r "$i" ]; then
        . $i
    fi

done

unset i

export G_BROKEN_FILENAMES=true

 

7.保存后执行以下命令：

 进入 /usr/bin/目录

        cd /usr/bin

        ln -s -f /usr/java/jdk1.6.0_20/jre/bin/java

        ln -s -f /usr/java/jdk1.6.0_20/bin/javac

8. 在命令行输入

        java -version

        屏幕输出:

        java version "jdk1.6.0_20"
        Java(TM) 2 Runtime Environment, Standard Edition (build jdk1.6.0_20)
        Java HotSpot(TM) Client VM (build jdk1.6.0_20, mixed mode)

3》安装tomcat

安装tomcat

下载apache-tomcat-5.5.29.tar.gz

2）#tar -zxvf apache-tomcat-5.5.29.tar.gz ；//解压

3）#cp -R apache-tomcat-5.5.29 /usr/local/tomcat ；//拷贝apache-tomcat-5.5.29到/usr/local/下并重命名为tomcat

4） /usr/local/tomcat/bin/startup.sh； //启动tomcat

显示 Using CATALINA_BASE: /usr/local/tomcat

Using CATALINA_HOME: /usr/local/tomcat

Using CATALINA_TEMDIR: /usr/local/tomcat/temp

Using JAVA_HOME: /usr/java/jdk1.6.0_20

到此tomcat已经安装完成，现在使用浏览器访问 http://localhost:8080，出现tomcat默认页面，说明已经安装成功。
