Pre-installation Configuration Tool

taospreset prepares one host or all hosts in a cluster for TDengine installation.

Usage

usage: taospreset [-h] [--model {local,ssh}] [--config CONFIG]
                  [--backend] [--disable-kysec] [--result RESULT]
                  [--version] [--log-level {debug,info}]

Option	Description
-m, --model	Configure the local host or all configured hosts over SSH; default: local
-f, --config	Full path to the configuration file; default: current directory
-b, --backend	Run in the background
-d, --disable-kysec	Disable the KySec security framework on Kylin Linux

The configuration format is shared with taosprecheck. It can define hosts, timezone, service state, core dump paths, and kernel and user limits.

[test_env]
firstep=192.168.0.1||fqdn=tdengine1||username=root||password=123456||port=22
secondep=192.168.0.2||fqdn=tdengine2||username=root||password=123456||port=22

[timezone]
tz=Asia/Shanghai

[services]
firewall=inactive
selinux=inactive

[coredump]
kernel.core_pattern=/data/taos/core/core-%%e-%%p

Configuration Scope

The tool can configure the system timezone, stop the firewall and SELinux services, apply system parameters, configure core dumps, replace a default localhost hostname with the configured FQDN, and add cluster host mappings to /etc/hosts.

Output

taospreset writes preset_report.md, which records the settings changed by the tool.

Examples

# Configure the current host
./taospreset

# Configure all hosts over SSH
./taospreset -m ssh

# Use a specific configuration
./taospreset -m ssh -f /path/to/preset.cfg

# Also disable KySec
./taospreset -m ssh -d
