Collectd+InfluxDB+Grafana监控系统搭建

环境配置

节点	配置	类型	操作系统
Sched	2G 2CPU 50GB ens3=>192.168.200.11	KVM虚拟机	CentOS 7
Nova	4G 2CPU 50GB ens3=>192.168.2000.12	KVM虚拟机	CentOS 7

Nova节点配置

安装Collectd

# yum install epel-release

# yum makecache

# yum install collectd -y

# systemctl start collectd

# systemctl enable collectd

配置Collectd

# vim /etc/collectd.conf

LoadPlugin network

<Plugin network>

        <Server "192.168.200.11" "25826">

        </Server>

</Plugin>

# systemctl restart collectd

# scp /usr/share/collectd/types.db root@192.168.200.11:~/

Sched节点配置

配置软件源

# cat <<EOF | sudo tee /etc/yum.repos.d/influxdb.repo

[influxdb]

name = InfluxDB Repository - RHEL \$releasever

baseurl = https://repos.influxdata.com/rhel/\$releasever/\$basearch/stable

enabled = 1

gpgcheck = 1

gpgkey = https://repos.influxdata.com/influxdb.key

EOF

# yum makecache

安装InfluxDB

# yum install influxdb -y

### 设置开机启动

# systemctl start influxdb

# systemctl enable influxdb

### 查询InfluxDB默认配置

# influxd config

### 如果不是使用标准的默认目录，需要手动修改目录权限

# chown -R influxdb:influxdb /mnt/influx

# chown -R influxdb:influxdb /mnt/db

配置InfluxDB

# mkdir -p /usr/share/collectd/

# mv types.db /usr/share/collectd/

# vim /etc/influxdb/influxdb.conf

[[collectd]]

  enabled = true

  bind-address = "0.0.0.0:25826"

### 查询配置是否生效

# influxd config

# systemctl restart influxdb

# systemctl stop firewalld

# systemctl disable firewalld

### 查询数据插入是否正常

> SHOW DATABASES

name: databases

name

----

_internal

collectd

> use collectd

Using database collectd

>

安装Grafana

# yum install https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-4.2.0-1.x86_64.rpm

### 设置开机启动

# systemctl daemon-reload

# systemctl start grafana-server

# systemctl status grafana-server

# systemctl enable grafana-server

### 访问http://192.168.200.11:3000/login，默认用户名密码admin:admin，默认配置信息可查询/etc/grafana/grafana.ini文件

配置Grafana

### 数据库默认用户名密码root:root
