influxdb+telegraf+chronograf集群部署

环境准备

influxdb enterprise运行条件最低需要三个meta nodes节点以及两个data nodes

Meta nodes之间使用TCP和Raft一致性协议通信，默认端口为8089

Meta nodes对外暴露8091,用于influxd-ctl命令进行交互

Data nodes通过8088进行数据同步，8086对于用户进行读写服务

在集群中，所有meta nodes节点必须要与data nodes节点保持通信。

mata nodes主要保存以下所有的元数据信息

• 集群中所有的节点以及角色
• 集群中所有存在的数据库和保留策略（retention policy）
• 保存所有分片和分片组信息
• 保存集群用户权限

data node保存所有原始时序数据以及元数据，包括

• measurement（数据表）
• tag key和value
• field key和value；

# systemctl start influxdb-meta
# systemctl enable influxdb-meta

将meta node节点加入集群

#influxd-ctl add-meta enterprise-meta-02:8091
#influxd-ctl add-meta enterprise-meta-03:8091

【部署influxdb-node节点】

#wget https://dl.influxdata.com/enterprise/releases/influxdb-data-1.8.2_c1.8.2.x86_64.rpm

#dpkg -i influxdb-data_1.8.2-c1.8.2_amd64.deb

#systemctl start influxd
#systemctl enable influxd

#将date node加入集群

#influxd-ctl add-data enterprise-data-01:8088
#influxd-ctl add-data enterprise-data-02:8088

最后我们在influxdb-meta节点上执行 influxd-ctl show查看集群节点状态

 截止目前influxdb集群部署完毕！END

【部署Telegrat】

Telegrat是一个用golang写的开源数据库收集agent，基于插件驱动，本身提供的输入和输出的插件非常丰富，当然有需求也可以自行编写，Telegraf是influxdbdb公司的时间序列平台TICK技术栈中的“T”，主要就是数据采集，用于主机性能数据，包括主机CPU,内存，io，进程状态，服务状态；

# yum install wget;wget https://dl.influxdata.com/kapacitor/releases/kapacitor-1.5.6-1.x86_64.rpm

# yum localinstall -y kapacitor-1.5.6-1.x86_64.rpm

# wget https://dl.influxdata.com/chronograf/releases/chronograf-1.8.7.x86_64.rpm

# yum localinstall -y chronograf-1.8.7.x86_64.rpm

#yum install -y telegraf

#vim /etc/telegraf/telegraf.conf

[[inputs.diskio]]
[[inputs.kernel]]
[[inputs.mem]]
[[inputs.processes]]
[[inputs.swap]]
[[inputs.system]]

 #systemctl restart telegraf 

#systemctl enable telegraf

# telegraf --config /etc/telegraf/telegraf.conf --input-filter cpu:mem --output-filter influxdb #生成具有特定输入和输出的配置文件，可以使用--input-filter和--output-filter标志

 

 此时我们可以去192.168.60.101上的influxdb数据库中查看一下是否已经生成相应的库文件

  接下来我们可配置Chronograf的数据源，让chronorag连接influxdb数据库，并进行数据可视化展示
