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。由于有了Sun 的参与和支持，最新的Servlet 和JSP 规范总是能在Tomcat 中得到体现，Tomcat 5支持最新的Servlet 2.4 和JSP 2.0 规范。因为Tomcat 技术先进、性能稳定，而且免费，因而深受Java 爱好者的喜爱并得到了部分软件开发商的认可，成为目前比较流行的Web 应用服务器。
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。对于一个初学者来说，可以这样认为，当在一台机器上配置好Apache 服务器，可利用它响应HTML（标准通用标记语言下的一个应用）页面的访问请求。实际上Tomcat是Apache 服务器的扩展，但运行时它是独立运行的，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。
诀窍是，当配置正确时，Apache 为HTML页面服务，而Tomcat 实际上运行JSP 页面和Servlet。另外，Tomcat和IIS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Apache服务器。目前Tomcat最新版本为9.0。

tomcat就是传说中的中间件之一，tomcat本身是一个容器，专门用来运行java程序，java语言开发的网页.jsp就应该运行于tomcat中。而tomcat本身的运行也依赖于jdk环境。

安装tomcat

//安装依赖包[root@localhost ~]# yum -y install java-11-openjdk-devel java-11-openjdk

//解压安装包[root@localhost ~]# tar xf apache-tomcat-9.0.46.tar.gz[root@localhost ~]# lsanaconda-ks.cfg  apache-tomcat-9.0.46  apache-tomcat-9.0.46.tar.gz  scripts//移动到/usr/local/tomcat下[root@localhost ~]# mv apache-tomcat-9.0.46 /usr/local/tomcat

//启动tomcat[root@localhost tomcat]# /usr/local/tomcat/bin/startup.sh Using CATALINA_BASE:   /usr/local/tomcatUsing CATALINA_HOME:   /usr/local/tomcatUsing CATALINA_TMPDIR: /usr/local/tomcat/tempUsing JRE_HOME:/usrUsing CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jarUsing CATALINA_OPTS:   Tomcat started.[root@localhost tomcat]# ss -antlState     Recv-Q    Send-Q    Local Address:Port       Peer Address:Port   Process    LISTEN    0 128     0.0.0.0:22      0.0.0.0:* LISTEN    0 128[::]:22 [::]:* LISTEN    0 1    [::ffff:127.0.0.1]:8005  *:* LISTEN    0 100   *:8080  *:*

配置管理界面Manager App

[root@localhost conf]# vim tomcat-users.xml//把下列两行加到这个配置文件的倒数第二行<role rolename="manager-gui"/><user username="tomcat" password="s3cret" roles="manager-gui"/>[root@localhost tomcat]# lsbin   conf     lib      logs    README.md      RUNNING.txt  webappsBUILDING.txt  CONTRIBUTING.md  LICENSE  NOTICE  RELEASE-NOTES  temp work[root@localhost tomcat]# cd webapps/[root@localhost webapps]# lsdocs  examples  host-manager  manager  ROOT[root@localhost webapps]# cd manager/[root@localhost manager]# lscss  images  index.jsp  META-INF  status.xsd  WEB-INF  xform.xsl[root@localhost manager]# cd META-INF/[root@localhost META-INF]# lscontext.xml[root@localhost META-INF]# vim context.xml allow="192\.168\.100\.\d+|127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />在这个文件中加入要访问的ip网段。
