今天下午本機啟動tomcat的時候遇到了一個問題腻惠。
嚴重: StandardServer.await: create[localhost:8005]:

這種問題一般是由于 Mac 下 /etc/hosts文件的問題捉邢，可能是添加了無法解析綁定的ip盖桥。我的問題是host的軟件將自身文件中的localhost ip改成了127.0.0.0。正常應該是127.0.0.1狠裹。
LookBack地址
特殊的IP地址段：
127.x.x.x
這是大家最熟悉不過的本地loopback地址病蛉，在windows和linux上等價于localhost。
我們習慣于使用127.0.0.1窟哺，實際上泻轰，
如果你在命令行下ping 127.0.0.1-127.255.255.254之間的任意地址，結果都是一樣的且轨，它們是等價的浮声。
正常的網(wǎng)絡包從ip層進入鏈路層，然后發(fā)送到網(wǎng)絡上殖告，
而發(fā)向loopback地址的包阿蝶，直接在IP層短路了，也就是發(fā)到IP層的包直接被IP層接收了黄绩，不再向下發(fā)送羡洁。
