117笔记问答在Ubuntu上部署InfluxDB集群需要以下几个步骤：
- 安装InfluxDB
首先，在每个节点上安装InfluxDB。可以使用以下命令来添加InfluxDB的存储库并安装软件包：
wget -qO- https://repos.influxdata.com/influxdb.key | sudo apt-key add -
source /etc/lsb-release
echo "deb https://repos.influxdata.com/${DISTRIB_ID,,} ${DISTRIB_CODENAME} stable" | sudo tee /etc/apt/sources.list.d/influxdb.list
sudo apt-get update && sudo apt-get install influxdb
- 配置InfluxDB
在每个节点上，编辑/etc/influxdb/influxdb.conf文件，以配置数据和元数据存储、HTTP API绑定地址、端口等。例如：
[meta] dir = "/var/lib/influxdb/meta" bind-address = "0.0.0.0:8088" retention-autocreate = true logging-enabled = true [data] dir = "/var/lib/influxdb/data" wal-dir = "/var/lib/influxdb/wal" query-log-enabled = true cache-max-memory-size = 1073741824 cache-snapshot-memory-size = 26214400 cache-snapshot-write-cold-duration = "10m0s" compact-full-write-cold-duration = "4h0m0s" max-series-per-database = 1000000 max-values-per-tag = 100000 max-concurrent-compactions = 0 trace-logging-enabled = false [coordinator] write-timeout = "10s" max-concurrent-queries = 0 query-timeout = "0s" log-queries-after = "0s" max-select-point = 0 max-select-series = 0 max-select-buckets = 0 [retention] enabled = true check-interval = "30m0s" [shard-precreation] enabled = true check-interval = "10m0s" advance-period = "30m0s" [admin] enabled = false bind-address = ":8083" https-enabled = false https-certificate = "/etc/ssl/influxdb.pem" [http] enabled = true bind-address = ":8086" auth-enabled = false log-enabled = true write-tracing = false pprof-enabled = false https-enabled = false https-certificate = "/etc/ssl/influxdb.pem" https-private-key = "" max-row-limit = 10000 max-connection-limit = 0 shared-secret = "" realm = "InfluxDB" unix-socket-enabled = false bind-socket = "/var/run/influxdb.sock" [subscriber] enabled = true http-timeout = "30s" insecure-skip-verify = false ca-certs = "" write-concurrency = 40 write-buffer-size = 1000
- 配置集群
在每个数据节点上，编辑/etc/influxdb/influxdb.conf文件，添加[cluster]部分以配置集群通信。例如：
[cluster] dial-timeout = "1s" shard-writer-timeout = "5s" shard-reader-timeout = "0" max-remote-write-connections = 10 cluster-tracing = false
在每个元数据节点上，编辑/etc/influxdb/influxdb.conf文件，添加[enterprise]部分以配置企业许可证和注册信息（如果有）。例如：
[enterprise] registration-enabled = false registration-server-url = "" license-key = "" license-path = ""
- 启动InfluxDB
在每个节点上，使用以下命令启动InfluxDB服务：
sudo systemctl start influxdb
- 初始化集群
在一个元数据节点上，使用以下命令初始化集群：
influxd-ctl init
这将输出一个示例命令，用于将其他数据节点添加到集群中。例如：
influxd-ctl join:8088
- 添加数据节点
在其他数据节点上，运行上一步中生成的join命令，将它们添加到集群中。
- 验证集群状态
在任何元数据节点上，使用以下命令查看集群状态：
influxd-ctl show
这将显示集群中所有节点的状态。如果一切正常，您现在应该已经成功部署了一个InfluxDB集群。
