模块：NODE

配置目标服务器，纳管主机节点，并将其调整至描述的状态。也包括节点上的 VIP，HAProxy 以及监控组件。

纳管节点，将其调整至所需状态，并进行监控。 配置 | 管理 | 剧本 | 监控 | 参数

概念

节点是硬件资源的抽象，它可以是裸机、虚拟机、容器或者是 k8s pods：只要装着操作系统，可以使用 CPU/内存/磁盘/网络 资源就行。

在 Pigsty 中存在不同类型的节点，它们的区别主要在于安装了不同的模块

在单机安装时，当前节点会被同时视作为管理节点、基础设施节点、PGSQL 节点，当然，它也是一个普通的节点。

普通节点

你可以使用 Pigsty 管理节点，并在其上安装模块。node.yml 剧本将调整节点至所需状态。以下服务默认会被添加到所有节点：

组件 端口 描述 状态
Node Exporter 9100 节点监控指标导出器 默认启用
HAProxy Admin 9101 HAProxy 管理页面 默认启用
Promtail 9080 日志收集代理 默认启用
Docker Daemon 9323 启用容器支持 按需启用
Keepalived - 负责管理主机集群 L2 VIP 按需启用
Keepalived Exporter 9650 负责监控 Keepalived 状态 按需启用

此外，您可以为节点选装 Docker 与 Keepalived（及其监控 keepalived exporter），这两个组件默认不启用。

ADMIN节点

在一套 Pigsty 部署中会有且只有一个管理节点，由 admin_ip 指定。在单机安装的配置过程中，它会被被设置为该机器的首要IP地址。

该节点将具有对所有其他节点的 ssh/sudo 访问权限：管理节点的安全至关重要，请确保它的访问受到严格控制。

通常管理节点与基础设施节点（infra节点）重合。如果有多个基础设施节点，管理节点通常是所有 infra 节点中的第一个，其他的作为管理节点的备份。

INFRA节点

一套 Pigsty 部署可能有一个或多个 基础设施节点（INFRA节点），在大型生产环境中可能会有 2 ~ 3 个。

配置清单中的 infra 分组列出并指定了哪些节点是INFRA节点，这些节点会安装 INFRA 模块（DNS、Nginx、Prometheus、Grafana 等…）。

管理节点通常是是INFRA节点分组中的第一台，其他INFRA节点可以被用作"备用"的管理节点。

组件 端口 域名 描述
Nginx 80 h.pigsty Web服务门户（也用作yum/atp仓库）
AlertManager 9093 a.pigsty 告警聚合分发
Prometheus 9090 p.pigsty 时间序列数据库（收存监控指标）
Grafana 3000 g.pigsty 可视化平台
Loki 3100 - 日志收集服务器
PushGateway 9091 - 接受一次性的任务指标
BlackboxExporter 9115 - 黑盒监控探测
DNSMASQ 53 - DNS 服务器
Chronyd 123 - NTP 时间服务器
PostgreSQL 5432 - Pigsty CMDB 和默认数据库
Ansible - - 运行剧本

PGSQL节点

安装了 PGSQL 模块的节点被称为 PGSQL 节点。节点和 PostgreSQL 实例是1:1部署的。

在这种情况下，PGSQL节点可以从相应的 PostgreSQL 实例上借用身份：node_id_from_pg 参数会控制这一点。

组件 端口 描述 状态
Postgres 5432 Pigsty CMDB 默认启用
Pgbouncer 6432 Pgbouncer 连接池服务 默认启用
Patroni 8008 Patroni 高可用组件 默认启用
Haproxy Primary 5433 主连接池：读/写服务 默认启用
Haproxy Replica 5434 副本连接池：只读服务 默认启用
Haproxy Default 5436 主直连服务 默认启用
Haproxy Offline 5438 离线直连：离线读服务 默认启用
Haproxy service 543x PostgreSQL 定制服务 按需定制
Haproxy Admin 9101 监控指标和流量管理 默认启用
PG Exporter 9630 PG 监控指标导出器 默认启用
PGBouncer Exporter 9631 PGBouncer 监控指标导出器 默认启用
Node Exporter 9100 节点监控指标导出器 默认启用

Docker Daemon 9323 Docker 守护进程 按需启用
keepalived - 为整个集群绑定 L2 VIP 按需启用
Keepalived Exporter 9650 Keepalived 指标导出器 按需启用

配置

Pigsty使用IP地址作为节点的唯一身份标识，该IP地址应当是数据库实例监听并对外提供服务的内网IP地址。

node-test:
  hosts:
    10.10.10.11: { nodename: node-test-1 }
    10.10.10.12: { nodename: node-test-2 }
    10.10.10.13: { nodename: node-test-3 }
  vars:
    node_cluster: node-test

该IP地址必须是数据库实例监听并对外提供服务的IP地址，但不宜使用公网IP地址。尽管如此，用户并不一定非要通过该IP地址连接至该数据库。 例如，通过SSH隧道或跳板机中转的方式间接操作管理目标节点也是可行的。 但在标识数据库节点时，首要IPv4地址依然是节点的核心标识符。这一点非常重要，用户应当在配置时保证这一点。 IP地址即配置清单中主机的inventory_hostname ，体现为<cluster>.hosts对象中的key。除此之外，每个节点还有两个额外的 身份参数：

名称 类型 层级 必要性 说明
inventory_hostname ip - 必选 节点IP地址
nodename string I 可选 节点名称
node_cluster string C 可选 节点集群名称

nodename 与 node_cluster 两个参数是可选的，如果不提供，会使用节点现有的主机名，和固定值 nodes 作为默认值。 在 Pigsty 的监控系统中，这两者将会被用作节点的 集群标识 （cls） 与 实例标识（ins） 。

对于 PGSQL节点 来说，因为Pigsty默认采用PG:节点独占1:1部署，因此可以通过 node_id_from_pg 参数， 将 PostgreSQL 实例的身份参数（ pg_cluster 与 pg_seq） 借用至节点的ins与cls标签上，从而让数据库与节点的监控指标拥有相同的标签，便于交叉分析。

#nodename:                # [实例] # 节点实例标识，如缺失则使用现有主机名，可选，无默认值
node_cluster: nodes       # [集群] # 节点集群标识，如缺失则使用默认值'nodes'，可选
nodename_overwrite: true          # 用 nodename 覆盖节点的主机名吗？
nodename_exchange: false          # 在剧本主机之间交换 nodename 吗？
node_id_from_pg: true             # 如果可行，是否借用 postgres 身份作为节点身份？

您还可以为主机集群配置丰富的功能参数，例如，使用节点集群上的 HAProxy 对外提供负载均衡，暴露服务，或者为集群绑定一个 L2 VIP。

管理

下面是 Node 模块中常用的管理操作：

更多问题请参考 FAQ：NODE

添加节点

要将节点添加到 Pigsty，您需要对该节点具有无密码的 ssh/sudo 访问权限。

您也可以选择一次性添加一个集群，或使用通配符匹配配置清单中要加入 Pigsty 的节点。

# ./node.yml -l <cls|ip|group>        # 向 Pigsty 中添加节点的实际剧本
# bin/node-add <selector|ip...>       # 向 Pigsty 中添加节点
bin/node-add node-test                # 初始化节点集群 'node-test'
bin/node-add 10.10.10.10              # 初始化节点  '10.10.10.10'

移除节点

要从 Pigsty 中移除一个节点，您可以使用以下命令：

# ./node-rm.yml -l <cls|ip|group>    # 从 pigsty 中移除节点的实际剧本
# bin/node-rm <cls|ip|selector> ...  # 从 pigsty 中移除节点
bin/node-rm node-test                # 移除节点集群 'node-test'
bin/node-rm 10.10.10.10              # 移除节点 '10.10.10.10'

您也可以选择一次性移除一个集群，或使用通配符匹配配置清单中要从 Pigsty 移除的节点。

创建管理员

如果当前用户没有对节点的无密码 ssh/sudo 访问权限，您可以使用另一个管理员用户来初始化该节点：

node.yml -t node_admin -k -K -e ansible_user=<另一个管理员>   # 为另一个管理员输入 ssh/sudo 密码以完成此任务

绑定VIP

您可以在节点集群上绑定一个可选的 L2 VIP，使用 vip_enabled 参数。

proxy:
  hosts:
    10.10.10.29: { nodename: proxy-1 } # 您可以显式指定初始的 VIP 角色：MASTER / BACKUP
    10.10.10.30: { nodename: proxy-2 } # , vip_role: master }
  vars:
    node_cluster: proxy
    vip_enabled: true
    vip_vrid: 128
    vip_address: 10.10.10.99
    vip_interface: eth1
./node.yml -l proxy -t node_vip     # 首次启用 VIP
./node.yml -l proxy -t vip_refresh  # 刷新 vip 配置（例如指定 master）

2 - 常见问题

Pigsty NODE 主机节点模块常见问题答疑

如何配置主机节点上的NTP服务？

NTP对于生产环境各项服务非常重要，如果没有配置 NTP，您可以使用公共 NTP 服务，或管理节点上的 Chronyd 作为标准时间。

如果您的节点已经配置了 NTP，可以通过设置 node_ntp_enabled 为 false 来保留现有配置，不进行任何变更。

否则，如果您有互联网访问权限，可以使用公共 NTP 服务，例如 pool.ntp.org。

如果您没有互联网访问权限，可以使用以下方式，确保所有环境内的节点与管理节点时间是同步的，或者使用其他内网环境的 NTP 授时服务。

node_ntp_servers:                 # /etc/chrony.conf 中的 ntp 服务器列表
  - pool cn.pool.ntp.org iburst
  - pool ${admin_ip} iburst       # 假设其他节点都没有互联网访问，那么至少与 Admin 节点保持时间同步。

如何在节点上强制同步时间？

为了使用 chronyc 来同步时间。您首先需要配置 NTP 服务。

ansible all -b -a 'chronyc -a makestep'     # 同步时间

您可以用任何组或主机 IP 地址替换 all，以限制执行范围。

远程节点无法通过SSH访问怎么办？

如果目标机器隐藏在SSH跳板机后面， 或者进行了一些无法直接使用ssh ip访问的自定义操作， 可以使用诸如 ansible_port 或 ansible_host 这一类Ansible连接参数来指定各种 SSH 连接信息，如下所示：

pg-test:
  vars: { pg_cluster: pg-test }
  hosts:
    10.10.10.11: {pg_seq: 1, pg_role: primary, ansible_host: node-1 }
    10.10.10.12: {pg_seq: 2, pg_role: replica, ansible_port: 22223, ansible_user: admin }
    10.10.10.13: {pg_seq: 3, pg_role: offline, ansible_port: 22224 }

远程节点SSH与SUDO需要密码怎么办？

执行部署和更改时，使用的管理员用户必须对所有节点拥有ssh和sudo权限。无需密码免密登录。

您可以在执行剧本时通过-k|-K 参数传入ssh和sudo密码，甚至可以通过-eansible_host=<another_user>使用另一个用户来运行剧本。

但是，Pigsty强烈建议为管理员用户配置SSH无密码登录以及无密码的sudo。

如何使用现有管理员创建专用管理员用户？

使用以下命令，使用该节点上现有的管理员用户，创建由node_admin_username 定义的新的标准的管理员用户。

./node.yml -k -K -e ansible_user=<another_admin> -t node_admin

如何使用节点上的HAProxy对外暴露服务？

您可以在配置中中使用haproxy_services 来暴露服务，并使用 node.yml -t haproxy_config,haproxy_reload 来更新配置。

以下是使用它暴露MinIO服务的示例：暴露MinIO服务

为什么我的 /etc/yum.repos.d/* 全没了？

Pigsty会在infra节点上构建的本地软件仓库源中包含所有依赖项。而所有普通节点会根据 node_repo_modules 的默认配置 local 来引用并使用 Infra 节点上的本地软件源。

这一设计从而避免了互联网访问，增强了安装过程的稳定性与可靠性。所有原有的源定义文件会被移动到 /etc/yum.repos.d/backup 目录中，您只要按需复制回来即可。

如果您想在普通节点安装过程中保留原有的源定义文件，将 node_repo_remove 设置为false即可。

如果您想在 Infra 节点构建本地源的过程中保留原有的源定义文件，将 repo_remove 设置为false即可。

为什么我的命令行提示符变样了？怎么恢复？

Pigsty 使用的 Shell 命令行提示符是由环境变量 PS1 指定，定义在 /etc/profile.d/node.sh 文件中。

如果您不喜欢，想要修改或恢复原样，可以将这个文件移除，重新登陆即可。

为什么我的主机名变了？

在两种情况下，Pigsty 会修改您的节点主机名：

如果您不希望修改主机名，可以在全局/集群/实例层面修改 nodename_overwrite 参数为 false （默认值为 true）。

详情请参考 NODE_ID 一节。

腾讯云的 OpenCloudOS 有什么兼容性问题？

OpenCloudOS 上的 softdog 内核模块不可用，需要从 node_kernel_modules 中移除。在配置文件全局变量中添加以下配置项以覆盖：

node_kernel_modules: [ br_netfilter, ip_vs, ip_vs_rr, ip_vs_wrr, ip_vs_sh ]
