红帽全球峰会第 8 章 强化共享文件系统服务(Manila)
共享文件系统服务(manila)提供了一组服务，用于在多项目云环境中管理共享文件系统。它类似于 OpenStack 通过块存储服务(cinder)项目提供基于块的存储管理。通过 manila，您可以创建共享文件系统并管理其属性，如可见性、可访问性和使用量配额。
如需有关 manila 的更多信息，请参阅存储指南： https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.0/html-single/storage_guide/
8.1. manila 的安全注意事项
Manila 通过 keystone 注册，允许您使用 manila endpoint 命令找到 API。例如：
manila endpoints
$ manila endpoints

默认情况下，manila API 服务只侦听带有 tcp6 的端口 8786，它支持 IPv4 和 IPv6。
Manila 使用多个配置文件；这些文件存储在 /var/lib/config-data/puppet-generated/manila/ 中：
api-paste.ini manila.conf policy.json rootwrap.conf rootwrap.d ./rootwrap.d: share.filters
api-paste.ini
manila.conf
policy.json
rootwrap.conf
rootwrap.d
./rootwrap.d:
share.filters
建议您将 manila 配置为在非 root 服务帐户下运行，并更改文件权限，以便只有系统管理员才能修改它们。Manila 要求只有管理员能够写入配置文件，服务只能通过 manila 组中的组成员资格读取它们。其他用户不得读取这些文件，因为它们包含服务帐户密码。
只有 root 用户应该可以自己写入 rootwrap.conf 中的 配置，以及 manila-rootwrap rootwrap.d/share.filters 中的共享节点的 manila-rootwrap 命令过滤器。
