tomcat安装

1. Tomcat安装

1.1 软件准备

JDK下载：http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Tomcat下载：http://tomcat.apache.org/

因为jdk和Tomcat的版本对运维来说没什么区别，提供本文使用的软件下载地址：http://pan.baidu.com/s/1IpioA

2.2 部署java环境 （getconf LONG_BIT）查看系统位数

    [root@tomcat ~]# cd /application/tools/
    tar xf jdk-8u60-linux-x64.tar.gz -C /application/
    ln -s /application/jdk1.8.0_60 /application/jdk
    sed -i '$a export JAVA_HOME=/application/jdk
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar' /etc/profile
    source /etc/profile
    #→出现下面结果证明部署成功
    [root@tomcat ~]# java -version
    java version "1.8.0_60"
    Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
    Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

2.3 安装Tomcat

    tar xf apache-tomcat-8.0.27.tar.gz -C /application/
    ln -s /application/apache-tomcat-8.0.27 /application/tomcat
    echo 'export TOMCAT_HOME=/application/tomcat'>>/etc/profile
    source /etc/profile
    chown -R root.root /application/jdk/ /application/tomcat/
    [root@tomcat ~]# tail -4 /etc/profile
    export JAVA_HOME=/application/jdk
    export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
    export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
    export TOMCAT_HOME=/application/tomcat

2.4 Tomcat目录介绍

    [root@tomcat ~]# cd /application/tomcat/
    [root@tomcat tomcat]# tree -L 1

2.5 启动Tomcat

    #→启动程序/application/tomcat/bin/startup.sh
    #→关闭程序/application/tomcat/bin/shutdown.sh
    [root@tomcat ~]# /application/tomcat/bin/startup.sh
    Using CATALINA_BASE: /application/tomcat
    Using CATALINA_HOME: /application/tomcat
    Using CATALINA_TMPDIR: /application/tomcat/temp
    Using JRE_HOME: /application/jdk
    Using CLASSPATH: /application/tomcat/bin/bootstrap.jar:/application/tomcat/bin/tomcat-juli.jar
    Tomcat started.
    [root@tomcat ~]# netstat -tunlp|grep java
    tcp 0 0 :::8009 :::* LISTEN 4743/java 
    tcp 0 0 :::8080 :::* LISTEN 4743/java 
    [root@tomcat ~]# ps -ef|grep [j]ava
