标签：eal ati 轻量 tmp 进程 安装tomcat 配置 tar nec
tomcat 是 apache 软件基金会的核心项目，由 apache、SUN 等公司来一起研发。
tomcat是JSP+servlet的运行平台。
tomcat 服务器是一个免费的开放源代码的Web 应用服务器，属于轻量级应用服务器，在中小型系统和并发访问用户不是很多的场合下被普遍使用，是开发和调试JSP 程序的首选。实际上Tomcat 部分是Apache 服务器的扩展，但它是独立运行的，所以当你运行tomcat 时，它实际上作为一个与Apache 独立的进程单独运行的。
优点：
（1）免费的
（2）占用系统资源比较小
（3）跨平台性好，有JAVA环境就行
# tar xf jdk-7u67-linux-x64.tar.gz
# mv jdk1.7.0_67/ /usr/local/java
# vim /etc/profile.d/java.sh
export JAVA_HOME=/usr/local/java
export PATH=$JAVA_HOME/bin:$PATH
# source /etc/profile.d/java.sh
# java -version
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)# tar xf apache-tomcat-7.0.73.tar.gz
# mv apache-tomcat-7.0.73 /usr/local/tomcat
# useradd -d /usr/local/tomcat tomcat
# chown tomcat.tomcat /usr/local/tomcat/ -R
# cd /usr/local/tomcat/bin 命令：shutdown.sh 关闭tomcat；startup.sh启动tomcat
lib java的库 .jar
logs 日志
temp 临时文件
work 运行JSP脚本需要的class文件
conf 配置文件
webapps DocumentRoot == /var/www/html/
方法一:
# cd bin/# ./startup.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/local/java
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
# netstat -tanp |grep 8080
tcp 0 0 :::8080 :::* LISTEN 2045/java 方法二: system-V脚本
# vim /etc/init.d/tomcat
