linux上安装tomcat，启动tomcat报错

Cannot find /usr/local/tomcat/bin/setclasspath.sh
This file is needed to run this program

在 /usr/local/tomcat/bin目录下没有找到 setclasspath.sh （文件丢失）这个文件，缺少这个文件无法启动。建议重新下载一个Tomcat

JDK环境变量，tomcat环境变量都要配置好，再检查检查吧

bootstrap.jar catalina.sh configtest.bat digest.bat setclasspath.sh startup.bat tomcat-native.tar.gz version.bat
catalina-tasks.xml commons-daemon-native.tar.gz configtest.sh digest.sh shutdown.bat startup.sh tool-wrapper.bat version.sh
catalina.bat commons-daemon.jar daemon.sh setclasspath.bat shutdown.sh tomcat-juli.jar tool-wrapper.sh
