Ceph入门到精通-cephadm bootstrap命令大全
-
默认情况下，Ceph 守护进程将其日志输出发送到 stdout/stderr，后者被选中 由容器运行时（Docker或Podman）启动，并（在大多数系统上）发送到 日记。如果您希望 Ceph 将传统日志文件写入 ， 在引导期间使用该选项。
/var/log/ceph/$fsid--log-to-file -
较大的 Ceph 集群在以下情况下性能更好（Ceph 集群外部） 公有网络流量与（Ceph 集群内部）分离 群集流量。内部群集流量处理复制、恢复、 以及 OSD 守护程序之间的检测信号。您可以定义集群 网络，通过向子命令提供选项。此参数必须以 CIDR 表示法定义子网（例如或 ）。
--cluster-networkbootstrap10.90.90.0/24fe80::/64 -
cephadm bootstrap写入访问所需的文件 新群集。这个中心位置使 Ceph 成为可能 主机上安装的软件包（例如，允许访问 cephadm 命令行界面）来查找这些文件。/etc/ceph但是，使用 cephadm 部署的守护程序容器根本不需要。使用选项 将它们放在其他目录中（例如，）。这可能会有所帮助 避免与现有 Ceph 配置（cephadm 或 否则）在同一主机上。
/etc/ceph--output-dir ** . -
您可以将任何初始 Ceph 配置选项传递给新的 通过将它们放在标准的 ini 样式配置文件中进行群集 并使用该选项。例如：
--config ** $ cat <initial-ceph.conf [global] osd crush chooseleaf type = 0 EOF $ ./cephadm bootstrap --config initial-ceph.conf ... -
该选项可以选择哪个SSH 用户 Cephadm 将用于连接到主机。关联的 SSH 密钥将是 添加到 。您的用户 使用此选项指定必须具有无密码 sudo 访问权限。
--ssh-user ** /home/**/.ssh/authorized_keys -
如果在经过身份验证的注册表上使用容器，则需要 登录时，您可以添加参数：
-
--registry-json
包含登录信息的 JSON 文件的示例内容：
{"url":"REGISTRY_URL", "username":"REGISTRY_USERNAME", "password":"REGISTRY_PASSWORD"}Cephadm 将尝试登录到此注册表，以便它可以拉取您的容器 ，然后将登录信息存储在其配置数据库中。其他主机已添加到 然后，群集还将能够使用经过身份验证的注册表。
