Tomcat搭建jpress网站

Tomcat简介

Tomcat是Apache软件基金会（Apache Software Foundation）的Jakarta 项目中的一个核心项目，由Apache、Sun和其他一些公司及个人共同开发而成。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。Tomcat和Nginx、Apache(httpd)、lighttpd等Web服务器一样，具有处理HTML页面的功能，另外它还是一个Servlet和JSP容器，独立的Servlet容器是Tomcat的默认模式。不过，Tomcat处理静态HTML的能力不如Nginx/Apache服务器。目前Tomcat最新版本为9.0。Java容器还有resin、weblogic等。

JDK介绍

JDK是 Java 语言的软件开发工具包，主要用于移动设备、嵌入式设备上的java应用程序。JDK是整个java开发的核心，它包含了JAVA的运行环境（JVM+Java系统类库）和JAVA工具。
DK包含了一批用于Java开发的组件，其中包括：
javac：编译器，将后缀名为.java的源代码编译成后缀名为“.class”的字节码
java：运行工具，运行.class的字节码
jar：打包工具，将相关的类文件打包成一个文件
javadoc：文档生成器，从源码注释中提取文档，注释需匹配规范
jdb debugger：调试工具
jps：显示当前java程序运行的进程状态
javap：反编译程序
appletviewer：运行和调试applet程序的工具，不需要使用浏览器
javah：从Java类生成C头文件和C源文件。这些文件提供了连接胶合，使Java和C代码可进行交互。
javaws：运行JNLP程序
extcheck：一个检测jar包冲突的工具
apt：注释处理工具
jhat：java堆分析工具
jstack：栈跟踪程序
jstat：JVM检测统计工具
jstatd：jstat守护进程
jinfo：获取正在运行或崩溃的java程序配置信息
jmap：获取java进程内存映射信息
idlj：IDL-to-Java编译器。将IDL语言转化为java文件
policytool：一个GUI的策略文件创建和管理工具
jrunscript：命令行脚本运行

配置相关环境变量信息

[[email protected] opt]# cat >>/etc/profile<<‘EOF‘
export JAVA_HOME=/usr/local/jdk
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
export TOMCAT_HOME=/usr/local/tomcat
EOF
[[email protected] opt]# source /etc/profile

设置jdk程序目录权限信息

[[email protected] opt]# chown -R root.root /usr/local

检查所有环境变量信息是否配置成功

[[email protected] opt]# env|egrep -i "JAVA_HOME|PATH|CLASSPATH|TOMCAT_HOME"
TOMCAT_HOME=/usr/local/tomcat
PATH=/usr/local/jdk/bin:/usr/local/jdk/jre/bin:/application/jdk/bin:/application/jdk/jre/bin:/application/jdk/bin:/application/jdk/jre/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
JAVA_HOME=/usr/local/jdk
CLASSPATH=.:/usr/local/jdk/lib:/usr/local/jdk/jre/lib:/usr/local/jdk/lib/tools.jar

启动tomcat服务程序

[[email protected] opt]# /usr/local/tomcat/bin/startup.sh
[[email protected] opt]# netstat -lntup|grep java
