InfluxDB: Bash script to launch and configure two nodes

The script will setup two influxdb nodes, setup some users and download and load some sample data. It’s developed on a Mac but should work in linux (not tested yet but let me know if there’s any problem). I do plan further work on this, for example adding in InfluxDB-Relay . The script is available at my github .

Usage is as follows…

Source the script in the shell

. influxdb_setup.sh

This makes the following functions available…

influx_kill influx_run_q
influx_admin_user influx_launch_nodes influx_setup_cluster
influx_config1 influx_mkdir influx_stress
influx_config2 influx_murder influx_test_db_user_perms
influx_count_processes influx_noaa_db_user_perms influx_test_db_users
influx_create_test_db influx_noaa_db_users
influx_curl_sample_data influx_node1
influx_http_auth influx_node2
influx_import_file influx_remove_dir

You don’t need to know in detail what most of these do. To setup two nodes just do…

influx_setup_cluster

If all goes well you should see a message like below…

Restarted influx nodes. Logon to node1 with influx -port 8086 -username admin -password $(cat "${HOME}/rhys_influxdb/admin_pwd.txt")

Logon to a node with…

influx -port 8086 -username admin -password $(cat "${HOME}/rhys_influxdb/admin_pwd.txt")

Execute “show databases”…

name
----
test
NOAA_water_database
_internal

Execute “show users”…

user admin
---- -----
admin true
test_ro false
test_rw false
noaa_ro false
noaa_rw false

N.B. Password for these users can be found in text files in $HOME/rhys_influxdb/

Start working with some data…

SELECT * FROM h2o_feet LIMIT 5
name: h2o_feet
time level description location water_level
---- ----------------- -------- -----------
1439856000000000000 between 6 and 9 feet coyote_creek 8.12
1439856000000000000 below 3 feet santa_monica 2.064
1439856360000000000 between 6 and 9 feet coyote_creek 8.005
1439856360000000000 below 3 feet santa_monica 2.116
1439856720000000000 between 6 and 9 feet coyote_creek 7.887

To clean everything up you can call…

influx_murder

Please notes this will kill all influxd processes and remove all data files.
