The BASEDIR environment variable is not defined correctly This environment variable is needed to run this program

安装tomcat6.0.33在linux的根目录下，然后启动，总提示上面的错误，我就配置了许多环境变量：

CATALINA_BASE=/tomcat6

export CATALINA_BASE

CATALINA_HOME=/tomcat6

export CATALINA_HOME

CATALINA_TMPDIR=/tomcat6/temp

export CATALINA_TMPDIR

PATH=$CATALINA_HOME:PATH

export PATH

都设置了一遍，但是一点没有用。

最后到网上了查一下，说要把tomcat6/bin/中的所有的.sh文件具有执行功能

chmod 744 *.sh

如此就ok了

再执行

./startup.sh
