[vc_row][vc_column][vc_column_text]In this article will guide you on how to install InfluxDB on CentOS 8 \/ RHEL 8 to start monitoring and visualization of your network Infrastructure.
\nInfluxDB provides the repository for installing InfluxDB on CentOS 8 or RHEL 8<\/p>\n
InfluxDB is an open-source time series database developed written in Go by InfluxData. InfluxDB is optimized for fast, high-availability storage and retrieval of time series data for metrics analysis. This can be installed on a single server or a clustered.<\/p>\n
1. Add InfluxDB repository to your system,run the following command with sudo privileged.
\n[simterm]
\n$ sudo tee \/etc\/yum.repos.d\/influxdb.repo<<EOF
\n[influxdb]
\nname = InfluxDB Repository
\nbaseurl = https:\/\/repos.influxdata.com\/rhel\/7\/x86_64\/stable\/
\nenabled = 1
\ngpgcheck = 1
\ngpgkey = https:\/\/repos.influxdata.com\/influxdb.key
\nEOF
\n[\/simterm]<\/p>\n
2. Update your cache and confirm that the repository is working fine:
\n[simterm]
\n$ sudo dnf makecache
\n[\/simterm]<\/p>\n
3. You can now install InfluxDB since we added already on repositories
\nTo install InfluxDB run the following command.
\n[simterm]
\n$ sudo dnf -y install influxdb
\n[\/simterm]<\/p>\n

5.Start and enable InfluxDB service on CentOS 8 \/ RHEL 8 by running the command:
\n[simterm]
\n$ sudo systemctl enable –now influxdb
\n[\/simterm]<\/p>\n
6. Now check InfluxDB status to confirm it is running on the system.
\n[simterm]
\n$ systemctl status influxdb<\/p>\n
\u25cf influxdb.service – InfluxDB is an open-source, distributed, time series database
\nLoaded: loaded (\/usr\/lib\/systemd\/system\/influxdb.service; enabled; vendor preset: disabled)
\nActive: active (running) since Mon 2020-04-20 01:06:03 PST; 1min 45s ago

\n\u2514\u25007277 \/usr\/bin\/influxd -config \/etc\/influxdb\/influxdb.conf<\/p>\n
[\/simterm]<\/p>\n
7. Configure InfluxDB on the system firewall on CentOS 8 \/ RHEL 8, Allow or open the InfluxDB services on port 3000 via TCP on your server, by adding new firewall rules and by default, InfluxDB uses the following network ports:<\/p>\n
TCP port 8086 is used for client-server communication over InfluxDB\u2019s HTTP API
\nTCP port 8088 is used for the RPC service for backup and restore.<\/p>\n
To open it on the firewall, use the command:
\n[simterm]
\n$ sudo firewall-cmd –add-port=8086\/tcp –permanent
\n$ sudo firewall-cmd –reload
\n[\/simterm]<\/p>\n
8. Port mappings can be modified by changing the file \/etc\/influxdb\/influxdb.conf & If you make any change in the configuration file, restart influxdb service.
\n[simterm]
\n$ sudo systemctl restart influxdb
\n[\/simterm][\/vc_column_text][vc_column_text]9. Configure InfluxDB http Authentication
\nIf you need http authentication, modify influxdb http section to contain the following and un comment # auth-enabled
\n[simterm]
\n$ sudo vi \/etc\/influxdb\/influxdb.conf
\n[\/simterm]<\/p>\n
[simterm]
\n[http]
\n# Determines whether user authentication is enabled over HTTP\/HTTPS. -pr3p
\n# auth-enabled = true<\/p>\n
[\/simterm]
\n10. Restart InfluxDB services
\n[simterm]
\n$ sudo systemctl restart influxdb
\n[\/simterm]<\/p>\n
11. Create a user with an authentication password:
\n[simterm]
\ncurl -XPOST “http:\/\/localhost:8086\/query” –data-urlencode “q=CREATE USER \\
\nusername WITH PASSWORD ‘strongpassword’ WITH ALL PRIVILEGES”
\n[\/simterm]<\/p>\n
Note:
\n\u2013 username with your own username
\n\u2013 strongpassword with your own password ¬e that the password requires single quotes<\/p>\n
Now whenever you need to run any influxdb commands on the terminal, you need to specify username using -username and password using -password options.
\n[simterm]
\ninflux -username ‘username’ -password ‘password’
\n[\/simterm]<\/p>\n
For curl, use -u to specify username and password separated by a colon.
\n[simterm]
\ncurl -G http:\/\/localhost:8086\/query -u username:password –data-urlencode “q=SHOW DATABASES”
\n[\/simterm]<\/p>\n
By default, influxdb service is listening on all interfaces on port 8086.
\n[simterm]
\n$ ss -tunelp | grep 8086
\ntcp LISTEN 0 128 *:8086 *:* users:((“influxd”,pid=2072,fd=5)) uid:985 ino:37787 sk:6 v6only:0 <->
