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
--addr
address because of Docker or NAT network, you must manually set the--advertise-addr
address. - 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
.
--advertise-status-addr
- The address through which TiKV accesses service status from outside.
- Default: The value of
--status-addr
is used. - If the client cannot connect to TiKV through the
--status-addr
address because of Docker or NAT network, you must manually set the--advertise-status-addr
address. - For example, the internal IP address of Docker is
172.17.0.1
, while the IP address of the host is192.168.100.113
and the port mapping is set to-p 20180:20180
. In this case, set--advertise-status-addr="192.168.100.113:20180"
. The client can find this service through192.168.100.113:20180
.
-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
- 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".
