<span style="font-size:18px;">The BASEDIR environment variable is not defined correctly</span>  
  
启动tomcat时报错  
<strong>The BASEDIR environment variable is not defined correctly  
This environment variable is needed to run this program</strong>  
 这坑爹的中间件，害的我搞了半天 根据提示开始排查环境变量设置  
   
 以下是JDK 与tomcat的环境变量  
   
[root@localhost bin]# more /etc/profile  
   
JAVA_HOME=/usr/local/src/jdk1.6.0_32  
JRE_HOME=$JAVA_HOME/jre  
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/jre/lib/rt.jar  
export JAVA_HOME CLASSPATH  
  
CATALINA_1_BASE=/apache-tomcat-6.0.35/  
CATALINA_1_HOME=/apache-tomcat-6.0.35/  
export CATALINA_1_BASE  CATALINA_1_HOME  
  
没啥错误，这害得我狠被动啊，无意中打了一个ls命了恍然大悟  
  
  
[root@localhost bin]# ls -al
