根据网上搜到的解决方法
一，
在wrapper.properties配置文件找那中,添加超时时间配置

wrapper.ping.timeout=120
wrapper.startup.timeout=300

然后重新启动项目程序就可以正常运行了

二，
刚开始主机名不bogon对，这样改

[root@localhost logs]# vim /etc/hosts
127.0.0.1    bogon
#localhost localhost.localdomain localhost4 localhost4.localdomain4

::1         bogon
#localhost localhost.localdomain localhost6 localhost6.localdomain6

然后重启

上述两个步骤都试了，然后重启成功了
问题是下晚上再试主机名变回localhost

下午上次成功，应该是第一个措施成功的
