yum -y install epel-release
yum -y install collectd

配置

vi /etc/collectd.conf

Hostname    "docker-1"
FQDNLookup   true
Interval     10

<Plugin network>
    Server "172.16.114.201" "25826"
</Plugin>

启动

systemctl start collectd.service
systemctl enable collectd.service

influxdb

配置yum

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

安装

yum install influxdb

启动

systemctl start influxdb
systemctl enable influxdb

创建库

influx
CREATE DATABASE collectd
use collectd
CREATE USER "root" WITH PASSWORD 'root' WITH ALL PRIVILEGES

配置

vi /etc/influxdb/influxdb.conf

hostname = "172.16.114.201"
 [[collectd]]
    enabled = true
    bind-address = "172.16.114.201:25826"
    database = "collectd"
    #retention-policy = ""
    #/usr/share/collectd/types.db这个文件，安装collectd之后才会有，没有这个文件时，打开了这个配置，influx是启动不了的
    typesdb = "/usr/share/collectd/types.db"

重启

systemctl restart influxdb

查看25826这个端口是否已经监听，如果有，则代表启动正常

[root@localhost influxdb]# netstat -anp| grep 25826
udp        0      0 172.16.114.201:25826    0.0.0.0:*   125967/influxd
