JAVA_HOME nor the JRE_HOME environment variable is defined

通过 startup.bat 文件启动，报错

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
请按任意键继续. . .

检查环境变量, 明明配置了 JAVA_HOME 的，那就看起来不是环境变量的问题了

打开 bin 目录下的 Catalina.bat 文件, 在下面添加:

rem 添加下面两条
set JAVA_HOME=C:/Program Files/Java/jdk1.8.0_91
set JRE_HOME=C:/Program Files/Java/jdk1.8.0_91/jre

rem Copy CATALINA_BASE from CATALINA_HOME if not defined
if not "%CATALINA_BASE%" == "" goto gotBase
set "CATALINA_BASE=%CATALINA_HOME%"
:gotBase

然后重启即可，如果是 linux 系统将 set 使用 export 替换即可
