CentOS Unknown host问题导致Elastic Job项目启动出错

CentOS 前端之家
前端之家收集整理的这篇文章主要介绍了CentOS Unknown host问题导致Elastic Job项目启动出错，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

最近在CentOS6.5服务器上部署了一个web项目，启动时报如下错误：

在网上搜了一下，资料很少，有一个人说是curator-framework作为zookeeper客户端连接zookeeper服务器出错导致-------tomcat重启的时候，因为之前的tomcat中的线程还没有完全关闭，新启动tomcat就会报这个异常。 解决办法也容易，只要把tomcat的server.xml中的reloadable="true"改成false。

因为同样的代码部署在其他服务器上都没有报出这个错误，所以还是考虑服务器环境问题。刚好在另一个项目启动时连接dubbo的zookeeper注册中心报错：

这个问题网上的资料很多，我修改了/etc/hosts和/etc/hostname文件里的hostname后，重启项目问题解决。然后我想同样都是连接zookeeper错误，这2个错误会不会是同一个原因？回去重启了前面那个项目，果然再没有报错。
