今天在一个测试环境中启动jboss时，不能正常启动，后来找了一会儿才查到了原因，记录一下吧。
在jboss.log中可以看到“Could not create deployment: file:/usr/local/jboss/server/default/conf/jboss-service.xml”这样的记录，但我仔细查了一下并非权限的问题。后来找了很久原因，结合网上搜索，加上仔细看到了“Caused by: java.lang.RuntimeException: Exception creating identity: host_221-83: host_221-83”的记录；才基本确定了是由于hostname解析不了，所以jboss不能正常启动。
解决方案很简单，要么是配置DNS使其能够解析本机的hostname（可用命令hostname获取），要么修改/etc/hosts文件使其解析为127.0.0.1即可。
如，我的/etc/hosts就修改为如下，添加了本机的hostname为“host_221-83”。
127.0.0.1 host_221-83 localhost localhost.localdomain localhost4 localhost4.localdomain4
其实，网上其他人也会遇到这个问题的，至于为什么jboss启动需要去解析本机主机名，我也没有深入调查了。
网上其他人也遇到了类似问题，见：https://community.jboss.org/thread/64649?tstart=0
另外，顺手记录一个jboss启动的参数，加上 -b 0.0.0.0 或 –host=0.0.0.0 才能保证服务能够被域名/IP/localhost等方式访问到，否则默认是localhost才行。
/usr/local/jboss/bin/run.sh -b 0.0.0.0
关于遇到的jboss不能启动的问题的详细日志在jboss.log中，摘录如下：
