解决办法：是因为m1.lok文件被锁住，需要释放命令如下

[weblogic@cfnltest bin]$ fuser -u /home/weblogic/Oracle/Middleware/user_projects/domains/domain/servers/m1/tmp/m1.lok
/home/weblogic/Oracle/Middleware/user_projects/domains/domain/servers/m1/tmp/m1.lok: 26974(weblogic)
[weblogic@cfnltest bin]$ 
[weblogic@cfnltest bin]$ 
[weblogic@cfnltest bin]$kill -9 26974
[weblogic@cfnltest bin]$ fuser -u /home/weblogic/Oracle/Middleware/user_projects/domains/domain/servers/m1/tmp/m1.lok
