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 ~]# ls
anaconda-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/tomcat
Using CATALINA_HOME:   /usr/local/tomcat

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]# ls
bin           conf             lib      logs    README.md      RUNNING.txt  webapps
BUILDING.txt  CONTRIBUTING.md  LICENSE  NOTICE  RELEASE-NOTES  temp         work
[root@localhost tomcat]# cd webapps/
[root@localhost webapps]# ls
docs  examples  host-manager  manager  ROOT
[root@localhost webapps]# cd manager/
[root@localhost manager]# ls
css  images  index.jsp  META-INF  status.xsd  WEB-INF  xform.xsl
[root@localhost manager]# cd META-INF/
[root@localhost META-INF]# ls
context.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。

配置Host Manager

[root@localhost conf]# ls
Catalina             context.xml           logging.properties  tomcat-users.xsd
catalina.policy      jaspic-providers.xml  server.xml          web.xml
catalina.properties  jaspic-providers.xsd  tomcat-users.xml
[root@localhost conf]# vim tomcat-users.xml 
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>   //在配置文件中加入此行
<user username="zdj" password="123456" roles="manager-gui,admin-gui"/>   //加入admin-gui



因为修改了配置文件,,这里需要重启
[root@localhost tomcat]# ./bin/catalina.sh stop

Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Using CATALINA_OPTS:

//在这个文件中加入要访问的网段

查看一下服务器状态

添加jenkins服务

[root@localhost ~]# ls
anaconda-ks.cfg  jenkins.war  scripts
[root@localhost ~]# cp jenkins.war /usr/local/tomcat/webapps/
[root@localhost ~]# cd /usr/local/tomcat/webapps/
[root@localhost webapps]# ls
docs  examples  host-manager  jenkins  jenkins.war  manager  ROOT

查看密码
[root@localhost webapps]# cat /root/.jenkins/secrets/initialAdminPassword
f9770e45cc67460586e22f049b96e91d

配置完成。
