[15-12-1 0:41:29:544 CST] 00000001 AdminTool     A   ADMU0509I: 无法访问 server“server1”。它似乎已停止。
[15-12-1 0:41:29:545 CST] 00000001 AdminTool     A   ADMU0211I: 在文件 /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/logs/server1/stopServer.log 中可看到错误的详细信息


解决方法：系统时间超前了，看了一下：系统时间是12-1 证书时间是：Fri Dec 11 08:18:45 CST 2015  12-11
所以将系统时间调到12-11以后就行
