Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
linux 下 启动tomcat 报:
Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program
先看Tomcat的startup.bat,它调用了catalina.bat,而catalina.bat则调用了setclasspath.bat。只要在setclasspath.bat的开头声明环境变量,打开tomcat的bin目录下面的setclasspath.sh,添加红色部分,路径自己修改。windows 下用set。
