一、启动Weblogic控制台，报错了，搜寻百度很多人有此类问题，但是搜了许久没有明确答案，这里博主则分析一下报错，结合谷歌和官网，今天探讨一下分析思路，解决并不难。

二、从上面报错到的信息并分析：
1、提示输入了用户名和密码，那么首先要知道这个密码是什么，用户名密码是否正确？
Enter username to boot WebLogic server:renzhiyuan #创建域时指定的用户名（正确） Enter password to boot WebLogic server: #创建域时指定的密码（正确）
2、是否可以根据报错关键字匹配解决？谷歌可搜到相关词条，知识问题居多,但是没有准确答案。
*************************************************************************** The WebLogic Server encountered a critical failure Reason: Assertion violated ***************************************************************************
3、可不可以通过Weblogic 启动日志得到其它信息？并未得到日志出现。
[root@Weblogic logs]# ll /home/weblogic/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain/servers/renzhiyuan/logs 总用量 4 drwxr-x--- 2 weblogic weblogic 4096 2月 23 15:01 diagnostic_p_w_picpaths [root@Weblogic logs]# ll /home/weblogic/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain/servers/renzhiyuan/logs/diagnostic_p_w_picpaths/ 总用量 0 [root@Weblogic logs]#
4、再次分析报错，localhost相关，原来自己修改了主机名，导致的。（和官网解释吻合）
Caused By: java.lang.AssertionError: Could not obtain the localhost address. The most likely cause is an error in the network configuration of this machine.
4.1）修改hosts文件
[root@Weblogic ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 127.0.0.1 Weblogic 192.168.1.98 Weblogic [root@Weblogic ~]#
5、再次启动Weblogic，正常。

9、控制台登陆：
10、思路总结：
9.1）报错关键字搜索
9.2）日志查询
9.3）官网查看相关文档。
