TiKV Configuration Flags

TiKV supports some readable unit conversions for command line parameters.

  • File size (based on byte): KB, MB, GB, TB, PB (or lowercase)
  • Time (based on ms): ms, s, m, h

-A, --addr

  • The address that the TiKV server monitors
  • Default: "127.0.0.1:20160"
  • To deploy a cluster, you must use --addr to specify the IP address of the current host, such as "192.168.100.113:20160". If the cluster is run on Docker, specify the IP address of Docker as "0.0.0.0:20160".

--advertise-addr

  • The server advertise address for client traffic from outside
  • Default: ${addr}
  • If the client cannot connect to TiKV through the default monitoring address because of Docker or NAT network, you must manually set the advertise address explicitly.
  • For example, the internal IP address of Docker is 172.17.0.1, while the IP address of the host is 192.168.100.113 and the port mapping is set to -p 20160:20160. In this case, you can set --advertise-addr to "192.168.100.113:20160". The client can find this service through 192.168.100.113:20160.

--status-addr

  • The port through which the TiKV service status is listened
  • Default: "20180"
  • The Prometheus can access this status information via http://host:status_port/metrics.
  • The Profile can access this status information via http://host:status_port/debug/pprof/profile.

-C, --config

  • The config file
  • Default: ""
  • If you set the configuration using the command line, the same setting in the config file will be overwritten.

--capacity

  • The store capacity
  • Default: 0 (unlimited)
  • PD uses this flag to determine how to balance the TiKV servers. (Tip: you can use 10GB instead of 1073741824)

--data-dir

  • The path to the data directory
  • Default: "/tmp/tikv/store"

-L, --Log

  • The log level
  • Default: "info"
  • You can choose from trace, debug, info, warn, error, or off.

--log-file

  • The log file
  • Default: ""
  • If this flag is not set, logs will be written to stderr. Otherwise, logs will be stored in the log file which will be automatically rotated every day.

--pd

  • The address list of PD servers
  • Default: ""
  • To make TiKV work, you must use the value of --pd to connect the TiKV server to the PD server. Separate multiple PD addresses using comma, for example "192.168.100.113:2379, 192.168.100.114:2379, 192.168.100.115:2379".
