在红帽Linux系统下使用su – user 命令时候，出现了报错“Failed to open temporary lock”该如何解决呢？
报错信息：
# su - user CASCU092E Failed to open temporary lock file (Diagnostic information: 2). CASCU092E Failed to open temporary lock file (Diagnostic information: 2). CASCU092E Failed to open temporary lock file (Diagnostic information: 2). CASCU092E Failed to open temporary lock file (Diagnostic information: 2). CASCU092E Failed to open temporary lock file (Diagnostic information: 2).
解决方案：
我们使用strace命令追踪输出的过程中可以看到如下信息：
access("/tmp", W_OK|X_OK) = -1 EACCES (Permission denied) <0.000017>
access("/tmp", W_OK|X_OK) = -1 EACCES (Permission denied) <0.000015
open("/tmp/AIM57432", O_WRONLY|O_CREAT, 061001320) = -1 EACCES (Permission denied) <0.000023
write(2, "CASCU092E Failed to open temporary lock file (Diagnostic information: 2).\n", 74) = 74 <0.000022>剩余内容需解锁观看
