• linux 安装jdk 配置tomcat


    Linux(ubuntu)下安装JDK、Tomcat

     

     

    一、安装jdk

    1)首先以root用户登录进去,在根目录下建立/usr/java的目录,我们将下载的东西都放到该目录下去。

    2)参考的https://help.ubuntu.com/community/Java

    Manual method
    • oracle java 6 jre 32-bit
     $ wget http://download.oracle.com/otn-pub/java/jdk/6u34-b04/jre-6u34-linux-i586.bin
     $ chmod u+x jre-6u34-linux-i586.bin
     $ ./jre-6u34-linux-i586.bin
     $ sudo mkdir -p /usr/lib/jvm
     $ sudo mv jre1.6.0_34 /usr/lib/jvm/
     $ sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jre1.6.0_34/bin/java" 1
     $ sudo update-alternatives --install "/usr/lib/mozilla/plugins/libjavaplugin.so" "mozilla-javaplugin.so" "/usr/lib/jvm/jre1.6.0_34/lib/i386/libnpjp2.so" 1
     $ sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jre1.6.0_34/bin/javaws" 1
    or
    • oracle java 6 jdk 64-bit
     $ wget --no-cookies --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F" http://download.oracle.com/otn-pub/java/jdk/6u45-b06/jdk-6u45-linux-x64.bin
     $ chmod u+x jdk-6u45-linux-x64.bin
     $ ./jdk-6u45-linux-x64.bin
     $ sudo mv jdk1.6.0_45 /opt
     $ sudo update-alternatives --install "/usr/bin/java" "java" "/opt/jdk1.6.0_45/bin/java" 1
     $ sudo update-alternatives --install "/usr/bin/javac" "javac" "/opt/jdk1.6.0_45/bin/javac" 1
     $ sudo update-alternatives --install "/usr/lib/mozilla/plugins/libjavaplugin.so" "mozilla-javaplugin.so" "/opt/jdk1.6.0_45/jre/lib/amd64/libnpjp2.so" 1
     $ sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/opt/jdk1.6.0_45/bin/javaws" 1
    
    
    • IMPORTANT choose the java you installed as default

     $ sudo update-alternatives --config java
     $ sudo update-alternatives --config javac
    
    

    实际执行下列操作:

     $ wget --no-cookies --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F" http://download.oracle.com/otn-pub/java/jdk/6u45-b06/jdk-6u45-linux-x64.bin
     $ chmod u+x jdk-6u45-linux-x64.bin
     $ ./jdk-6u45-linux-x64.bin
     $ sudo mv jdk1.6.0_45 /opt
     $ sudo update-alternatives --install "/usr/bin/java" "java" "/opt/jdk1.6.0_45/bin/java" 1
     $ sudo update-alternatives --install "/usr/bin/javac" "javac" "/opt/jdk1.6.0_45/bin/javac" 1
     $ sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/opt/jdk1.6.0_45/bin/javaws" 1
    
     $update-alternatives --install /usr/bin/java  java /opt/jdk1.6.0_45/bin/java 300
     $update-alternatives --install /usr/bin/javac javac /opt/jdk1.6.0_45/bin/javac 300

    3)设置环境变量,在 /etc/profile中加入如下内容(可以使用vi进行编辑profile):

    export JAVA_HOME=/opt/jdk1.6.0_45/
    export JRE_HOME=/opt/jdk1.6.0_45/jre 
    export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
    export CLASSPATH=$CLASSPATH:.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

    4)然后运行source  /etc/profile使环境变量生效,貌似只能在当前命令窗口生效,最好重启下机器。

    5)使用java -version 查看是否显示版本信息。

    6)在终端执行命令 javac java 都能产生很多的信息,就说明安装成功了,你可以用一下例子测试下!

    public class hello {
    public static void main(String args [ ])
    {
    System.out.println("Hello World!");
    }
    }
    root@ubuntu: javac hello.java
    root@ubuntu: java hello

    如果终端有Hello World输出 证明一切都已经好了!

    二、安装Tomcat

    下面我们开始安装apache-tomcat ,首先从官网下载apache-tomcat的linux包apache-tomcat-6.0.35.tar.gz  下载地址如下  http://tomcat.apache.org/download-60.cgi 

    1.首先将tomcat安装包拷贝到/opt下 

    root@ubuntu: cp apache-tomcat-6.0.35.tar.gz /opt

    2.然后解压apache-tomcat-6.0.35.tar.gz包,解压后的目录为apache-tomcat-6.0.35

    root@ubuntu:cd /opt
    root@ubuntu:tar xzvf apache-tomcat-6.0.35.tar.gz

    3.然后在终端输入:

    [root@localhost heshan]# /opt/apache-tomcat-6.0.35/bin/startup.sh  // 启动Tomcat

    显示:

    Using CATALINA_BASE:   /opt/apache-tomcat-6.0.35
    Using CATALINA_HOME:   /opt/apache-tomcat-6.0.35
    Using CATALINA_TMPDIR: /opt/apache-tomcat-6.0.35/temp
    Using JRE_HOME:        /opt/jdk1.6.0_31/
    Using CLASSPATH:       /opt/apache-tomcat-6.0.35/bin/bootstrap.jar
    复制代码
    [root@localhost heshan]# cd /opt/apache-tomcat-6.0.35/logs      //切换到logs目录下
    [root@localhost heshan]# tail -f catalina.out     //显示Tomcat的控制台输出信息
    INFO: Deploying web application directory ServletTest
    init actionservlet
    Mar 24, 2012 1:33:32 PM org.apache.coyote.http11.Http11Protocol start
    INFO: Starting Coyote HTTP/1.1 on http-80
    Mar 24, 2012 1:33:32 PM org.apache.jk.common.ChannelSocket init
    INFO: JK: ajp13 listening on /0.0.0.0:8009
    Mar 24, 2012 1:33:32 PM org.apache.jk.server.JkMain start
    INFO: Jk running ID=0 time=0/38  config=null
    Mar 24, 2012 1:33:32 PM org.apache.catalina.startup.Catalina start
    INFO: Server startup in 2110 ms
    复制代码


    通过以上步骤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。
    现在说下怎么样关闭Tomcat

    [root@localhost logs]# /opt/apache-tomcat-6.0.35/bin/shutdown.sh 
    Using CATALINA_BASE:   /opt/apache-tomcat-6.0.353
    Using CATALINA_HOME:   /opt/apache-tomcat-6.0.35
    Using CATALINA_TMPDIR: /opt/apache-tomcat-6.0.35/temp
    Using JRE_HOME:        /opt/jdk1.6.0_31/
    Using CLASSPATH:       /opt/apache-tomcat-6.0.35/bin/bootstrap.jar

    这样就关闭了Tomcat,不过在我们我们启动Tomcat的时候最后先看一下Tomcat是否正在运行

    如下:

    复制代码
    [root@localhost logs]# ps -ef|grep tomcat
    root      5820     1 22 13:40 pts/2    00:00:01 /opt/jdk1.6.0_31//bin/java -Djava.util.logging.config.file=/opt/apache-tomcat-6.0.33/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.rmi.server.hostname=10.48.17.193 -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=true -Djava.endorsed.dirs=/opt/apache-tomcat-6.0.353/endorsed -classpath /opt/apache-tomcat-6.0.35/bin/bootstrap.jar -Dcatalina.base=/opt/apache-tomcat-6.0.35 -Dcatalina.home=/opt/apache-tomcat-6.0.35 -Djava.io.tmpdir=/opt/apache-tomcat-6.0.35/temp org.apache.catalina.startup.Bootstrap start
    
    root      5855 14306  0 13:40 pts/2    00:00:00 grep tomcat
    复制代码

     这时就说明Tomcat正在运行,所以我们必须按照上面的步骤先关闭Tomcat,然后再启动,否则会产生以一些问题。
    至此,我们在linux下已经安装好jdk和Tomcat了,我们也可以开始工作了。

     

    为了操作方便,在/usr/local 下建立软链接,名字是tomcat6

    cd /usr/local sudo ln -/opt/apache-tomcat-6.0.35 tomcat6
    测试tomcat是否能够正常启动
    shell>sudo /usr/local/tomcat6/bin/startup.sh

     

    四、tomcat开机自启动

    方法一:简单方法

    将tomcat的启动脚本命令如本例中:/opt/apache-tomcat-6.0.35/bin/startup.sh
    放进/etc/rc.local文件下即可,注意命令脚本需要放在 exit 0 之前。

    方法二:使用自启动工具 sysv-rc-conf
