HowTo Install influxdb on CentOs 7

First of all, we will need a basic CentOs 7 installation. There are no special requirements on what to select. Next, we will need to add the influxdb yum repository to this freshly installed CentOs 7. Use the following commands to add it to your system:

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

Now we can start the installation with the following command:

sudo yum install influxdb

Please answere “y” to all questions. You should see the following output then:

Now let’s start the influxdb service for the first time and also make it autostart when the system starts:

sudo /bin/systemctl start influxdb.service

sudo /bin/systemctl enable influxdb.service

On a standard CentOs 7 installation, the firewall needs to be opened for the influx db port ( TCP/8086 and TCP/8083 ), so let’s do it now:

firewall-cmd --permanent --zone=public --add-port=8086/tcp

firewall-cmd --permanent --zone=public --add-port=8083/tcp

firewall-cmd --reload

You should now be able to go to the web interface of your influxdb installation using the following url:

http://<serverip>:8083/

II. Config collectd.service

Để cấu hình monitor nginxI. Cai dat va cấu hinh nginx

II.Cấu hình trên collectd

$ yum install collectd-nginx

Nếu muốn monitor mysql thì cài

$ yum install collectd-mysql
