apache2+tomcat5.5 失误 mod_jk.handler() Error connecting to tomcat 120000

apache2+tomcat5.5 出错 mod_jk.handler() Error connecting to tomcat 120000
workers2.properties配置有点问题 ，

# more workers2.properties
[channel.socket:localhost:8009]
port=8009
host=localhost

我把 host=localhost   变成 host=127.0.0.1 ，问题即可解决了
