在用root用戶啟動(dòng)weblogic的時(shí)候會(huì)在所在域里產(chǎn)生root權(quán)限的文件，或者用root權(quán)限的文件覆蓋了部分原來(lái)存在的weblogic用戶所屬文件，當(dāng)再次切換到weblogic用戶后，啟動(dòng)的時(shí)候就會(huì)出現(xiàn)權(quán)限問(wèn)題，所以報(bào)告上面的錯(cuò)誤。這個(gè)錯(cuò)誤就是因?yàn)镋mbeddedLDAP.tran文件的權(quán)限變成了root的。

解決方法：

用root用戶登錄，將EmbeddedLDAP.log賦權(quán)給weblogic用戶。但是還有一系列的log文件需要賦權(quán)。索性把domains下的所有應(yīng)用全部賦權(quán)。

[root@mnhj02 ~]# chown -R weblogic:weblogic domains_dir

前一個(gè)weblogic是用戶，后一個(gè)weblogic是用戶所屬組，domains_dir是文件所在的路徑。
