tomcat服务器的配置与故障排除
时间：2022-11-17 17:00:00
大家好，今天分享tomcat 服务器
Tomcat 服务器是一个免费的开源代码Web 应用服务器
这是tomcat点击官网。
下面再Windows 在环境中，安装和配置
我用这个版本:(下载后需要解压)
打开tomcat。你可以看到里面的文件
bin: 这是操作它的脚本文件
conf : 这是tomcat 的配置文件
lib : 这里是它的jar包
logs : 这是它的日志文件
webapps：这是存储网站的资源
work : 这是它的工作文件
这里提一下，Windows下的tomcat服务，解压之后就可以使用
但是，启动时可能会遇到闪回问题
点击此文件
注意这两个文件
打开startup.bat (以下是其启动文件)
我们需要这个startup,bat 添加到这个文件中(在这个文件的前面)
SET JAVA_HOME= C:\Users\Administrator\.jdks\corretto-1.8.0_312（java jdk目录） SET JRE_HOME=C:\Users\Administrator\.jdks\corretto-1.8.0_312\jre SET CATALINA_HOME=E:\apache-tomcat-9.0.24-windows-x86\apache-tomcat-9.0.24 # 这是tomcat安装目录(因人而异) 截图是这样的
记得保存
打开shutdown.bat这个文件
在这个文件的第一行加上
SET JAVA_HOME= C:\Users\Administrator\.jdks\corretto-1.8.0_312 SET JRE_HOME=C:\Users\Administrator\.jdks\corretto-1.8.0_312\jre SET CATALINA_HOME=E:\apache-tomcat-9.0.24-windows-x86\apache-tomcat-9.0.24 记得保存
点击startup.bat这个文件
可以dos窗口以前台的形式运行(这是正常的)
如果我们刚刚没有配置相应的环境变量，这个地方就会闪回
这将导致启动失败
我们已经成功启动了tomcat 服务器
我们现在使用浏览器访问tomcat服务器 （http://localhost:8080/）
在我们进行网页访问的时候，startup.bat 文件的前台进程不可以断掉
否则浏览器的访问将出现问题：
这是关掉
再次运行：
这样就访问正常
也可以通过shutdown.bat 这个文件来关闭服务器
再次使用startup.bat 这个文件 来启动tomcat服务器
现在可以正常访问
这个文件是tomcat服务器非常重要的配置文件
这就是这个配置文件里所有的东西
这是我们默认指定的端口
这一行要注意一下
这里有5个web应用，我们要注意ROOT 这个文件
这就是首页的网页资源
注意这个文件
这就是index.jsp 的全部代码：
