我正在尝试从 mongodb.org 存储库在 CentOS 7.2 上安装 MongoDB。到目前为止一切都很好，但是主机已经为所有 MongoDB 数据文件创建了一个辅助磁盘 (/mongo)。这与 SELinux 权限冲突，导致 MongoDB 无法启动。我已经开始运行了setenforce 0，但这并不是我真正想要运行生产服务器的方式。

我有相当多的 Linux 经验，但我所有的 SELinux 经验只是将其关闭。我找到了这个 CentOS SELinux 教程，它让我想到了运行

会解决这个问题。之后，我做了一个touch /.autorelabel并重新启动。不幸的是，这并没有解决手头的问题。我将如何解决这个问题？

我刚刚使用Samba 提供的指南设置了 Samba 4 Active Directory 域。到目前为止一切顺利，我设法按照设置 Samba AD 成员服务器指南将我的文件服务器加入到该域。但是，我似乎无法让我的 Windows 8.1 Professional 设备加入此域。我在 Samba 站点上找到了将 Windows 客户端加入域指南，但这要么引发错误“指定的域不存在或无法联系”（当我以全部大写形式键入域名时）或引发更详细的错误（当我输入小写的域名时）：

 Note: This information is intended for a network administrator.  If you are not your network's administrator, notify the administrator that you received this information, which has been recorded in the file C:\Windows\debug\dcdiag.txt.

 The following error occurred when DNS was queried for the service location (SRV) resource record used to locate an Active Directory Domain Controller (AD DC) for domain "samba.local":

 The error was: "DNS name does not exist."
 (error code 0x0000232B RCODE_NAME_ERROR)

 The query was for the SRV record for _ldap._tcp.dc._msdcs.samba.local

 Common causes of this error include the following:>

 - The DNS SRV records required to locate a AD DC for the domain are not registered in DNS. These records are registered with a DNS server automatically when a AD DC is added to a domain. They are updated by the AD DC at set intervals. This computer is configured to use DNS servers with the following IP addresses:

 192.168.1.2

 - One or more of the following zones do not include delegation to its child zone:

 samba.local
 local
 . (the root zone)

我检查了/var/lib/samba/private/dns_update_list文件，它在里面。我唯一注意到的是，它前面有一个检查是否是读/写 DC。确切的行说

  ${IF_RWDC}SRV          _ldap._tcp.dc._msdcs.${DNSDOMAIN}                     ${HOSTNAME} 389

我的 DNS 域名（在配置期间指定）是samba.local. 有关设置的更多信息：

  Samba DC version:      4.1.13-Debian (running on Debian testing)
  Member server version: 4.1.14 (running on Fedora 21)
  Windows versions:      8.1 Professional and 10 Pro Tech Preview (both fully up to date)
  Server Role:           active directory domain controller
  Hostname:              DC1
  NetBIOS Domain:        SAMBA
  DNS Domain:            samba.local

我之前在 Windows 域方面的唯一经验是在 Server 2003R2 和 Windows XP 上，所以我对新版本的速度并不了解。
