用户执行权限错误，在node信息中‘CTL Username’应为'ctier'而不是root。
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.sh,而catalina.bat则调用了setclasspath.sh。只要在setclasspath.sh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。
