啓動tomcat的時候報錯：Cannot find /usr/tomcat/apache-tomcat-8.5.49//bin/setclasspath.sh

root@nuoniu-System-Product-Name:/usr/tomcat/tomcat-eureka/bin# ./startup.sh
Cannot find /usr/tomcat/apache-tomcat-8.5.49//bin/setclasspath.sh
This file is needed to run this program

解決：在tomcat裏面的bin的catalina.sh添加如下信息

export CATALINA_BASE=$CATALINA_BASE
export CATALINA_HOME=$CATALINA_HOME
export JAVA_HOME=/usr/jdk/jdk1.8.0_181
export JRE_HOME=/usr/jdk/jdk1.8.0_181/jre

然後重啓就可以了
