linux下安裝配置JDK+Tomcat+Mysql測試環境

1、系統環境

CentOS6.5

2、下載JDK，tomcat軟件包，官網可以下載，也可以用命令行下載

    Mysql使用yum安裝

3、linux安裝JDK

    1）下載JDK

       #wget http://download.oracle.com/otn-pub/java/jdk/8u45-b14/jdk-8u45-linux-x64.tar.gz?AuthParam=1434620688_1831ed06c98894056108fddcb5c59167

    2）下載後發現名字有點長，修改一下

        #mv jdk-8u45-linux-x64.tar.gz\?AuthParam\=1434620688_1831ed06c98894056108fddcb5c59167 jdk-8u45-linux-x64.tar.gz

    3）解壓到/usr/local/

       #tar -zxvf jdk-8u45-linux-x64.tar.gz -C /usr/local/

    4)設置JAVA環境變量

        打開/etc/profile添加

        #vim /etc/profile  

            #set java environment

            JAVA_HOME=/usr/local/jdk1.8.0_45

            CLASSPATH=.:$JAVA_HOME/lib/tools.jar

            PATH=$JAVA_HOME/bin:$PATH

            export JAVA_HOME CLASSPATH PATH

    5)source /etc/profile     #設置立即生效

    6)驗證，輸入java

    #java

    

Usage: java [-options] class [args...]

           (to execute a class)

   or  java [-options] -jar jarfile [args...]

           (to execute a jar file)

where options include:

    -d32  use a 32-bit data model if available

    -d64  use a 64-bit data model if available

    -server  to select the "server" VM

                  The default VM is server,

                  because you are running on a server-class machine.

4、安裝Tomcat

    1）下載tomcat

    #wget http://apache.fayea.com/tomcat/tomcat-6/v6.0.44/bin/apache-tomcat-6.0.44.tar.gz

    2)解壓

    #tar -zxvf apache-tomcat-6.0.44.tar.gz -C /usr/local/

    3）啓動tomcat

       # cd apache-tomcat-6.0.44/

       #./startup.sh

    4)訪問tomcat
