解决方法：

1.检查localhost的IP配置,配置地址/etc/hosts

确保有127.0.0.1  localhost

2.ip配置 /etc/sysconfig/network-script/ifcfg-lo  （我是用此方法后tomcat顺利启动）

ifconfig -lo 127.0.0.1  （临时有效，重启后又失败）

设置eth0和lo

ifcfg-lo 文件内容：

DEVICE=lo
IPADDR=127.0.0.1
ONBOOT=yes
NAME=loopback

 

ifcfg-eth0文件内容：

DEVICE=eth0
BOOTPROTO=static
TYPE=Ethernet
IPADDR=192.168.116.129
NETMASK=255.0.0.0
GATEWAY=192.168.0.1
ONBOOT=yes
NAME=loopback
