KingbaseES 如何开启并进入数据库
关键字:
KingbaseES、sys_ctl、ksql
一、数据库启动前环境检测
1.1 查看kingbase用户环境变量配置
图1-1 查看.bashrc环境变量配置
1.2 应用环境变量
[kingbase@node1 ~]$ source .bashrc
[kingbase@node1 ~]$ which ksql
/opt/Kingbase/ES/V8R6_021/Server/bin/ksql
[kingbase@node1 ~]$ which sys_ctl
/opt/Kingbase/ES/V8R6_021/Server/bin/sys_ctl
1.3 查看数据库数据存储路径
在数据库软件包安装目录的Logs目录下查看相关的日志,可以获取到数据库数据存储路径,如下图1-2所示:
图1-2 查看数据库数据存储路径
1.4 查看数据库配置文件信息
根据实际的业务场景,调整数据库的默认配置。

二、启动数据库服务
2.1 查看启动工具(sys_ctl)帮助信息
[kingbase@node1 ~]$ sys_ctl --help
sys_ctl is a utility to initialize, start, stop, or control a Kingbase server.
Usage:
sys_ctl start [-D DATADIR] [-l FILENAME] [-W] [-t SECS] [-s]
[-o OPTIONS] [-p PATH] [-c]
sys_ctl stop [-D DATADIR] [-m SHUTDOWN-MODE] [-W] [-t SECS] [-s]
sys_ctl restart [-D DATADIR] [-m SHUTDOWN-MODE] [-W] [-t SECS] [-s]
[-o OPTIONS] [-c]
sys_ctl reload [-D DATADIR] [-s]
sys_ctl status [-D DATADIR]
sys_ctl promote [-D DATADIR] [-W] [-t SECS] [-s]
sys_ctl logrotate [-D DATADIR] [-s]
sys_ctl kill SIGNALNAME PID
Common options:
-D, --kingbase-data=DATADIR location of the database storage area
-s, --silent only print errors, no informational messages
-t, --timeout=SECS seconds to wait when using -w option
-V, --version output version information, then exit
-w, --wait wait until operation completes (default)
-W, --no-wait do not wait until operation completes
-?, --help show this help, then exit
If the -D option is omitted, the environment variable KINGBASE_DATA is used.
Options for start or restart:
-c, --core-files allow kingbase to produce core files
-l, --log=FILENAME write (or append) server log to FILENAME
-o, --options=OPTIONS command line options to pass to kingbase
(Kingbase server executable) or initdb
-p PATH-TO-KINGBASE normally not necessary
Options for stop or restart:
-m, --mode=MODE MODE can be "smart", "fast", or "immediate"
Shutdown modes are:
smart quit after all clients have disconnected
fast quit directly, with proper shutdown (default)
immediate quit without complete shutdown; will lead to recovery on restart
Allowed signal names for kill:
ABRT HUP INT KILL QUIT TERM USR1 USR2

2.2 启动数据库服务
2.2.1 启动数据库服务
[kingbase@node1 data]$ sys_ctl start -D /data/kingbase/v8r6_021/data
waiting for server to start....2021-03-01 14:16:55.069 CST [26141] LOG: sepapower extension initialized

done
server started
2.2.2 查看数据库服务进程
[kingbase@node1 data]$ ps -ef |grep kingbase
/opt/Kingbase/ES/V8R6_021/Server/bin/kingbase -D /data/kingbase/v8r6_021/data
kingbase 26142 26141 0 14:16 ? 00:00:00 kingbase: logger
kingbase 26144 26141 0 14:16 ? 00:00:00 kingbase: checkpointer
kingbase 26145 26141 0 14:16 ? 00:00:00 kingbase: background writer
kingbase 26146 26141 0 14:16 ? 00:00:00 kingbase: walwriter
kingbase 26147 26141 0 14:16 ? 00:00:00 kingbase: autovacuum launcher
kingbase 26148 26141 0 14:16 ? 00:00:00 kingbase: stats collector
kingbase 26149 26141 0 14:16 ? 00:00:00 kingbase: ksh writer

kingbase 26152 26141 0 14:16 ? 00:00:00 kingbase: logical replication launcher
2.2.3 查看数据库服务端口状态
[kingbase@node1 data]$ netstat -an |grep :54321
tcp 0 0 0.0.0.0:54321 0.0.0.0:* LISTEN
tcp6 0 0 :::54321 :::* LISTEN
===从数据库服务进程状态及端口状态可知,数据库服务启动成功!===
三、连接数据库服务访问
3.1 数据库连接工具(ksql)帮助信息
[kingbase@node1 data]$ ksql --help
ksql is the Kingbase interactive terminal.
Usage:
ksql [OPTION]... [DBNAME [USERNAME]]
General options:
-c, --command=COMMAND run only single command (SQL or internal) and exit
-d, --dbname=DBNAME database name to connect to (default: "kingbase")
-f, --file=FILENAME execute commands from file, then exit
-l, --list list available databases, then exit
-v, --set=, --variable=NAME=VALUE
set ksql variable NAME to VALUE
(e.g., -v ON_ERROR_STOP=1)
-V, --version output version information, then exit
-X, --no-ksqlrc do not read startup file (~/.ksqlrc)
-1 ("one"), --single-transaction
execute as a single transaction (if non-interactive)
-?, --help[=options] show this help, then exit
--help=commands list backslash commands, then exit
--help=variables list special variables, then exit
Input and output options:
-a, --echo-all echo all input from script

-e, --echo-queries echo commands sent to server
-E, --echo-hidden display queries that internal commands generate
-L, --log-file=FILENAME send session log to file
-n, --no-readline disable enhanced command line editing (readline)
-o, --output=FILENAME send query results to file (or |pipe)
-q, --quiet run quietly (no messages, only query output)
-s, --single-step single-step mode (confirm each query)
-S, --single-line single-line mode (end of line terminates SQL command)
Output format options:
-A, --no-align unaligned table output mode
--csv CSV (Comma-Separated Values) table output mode
-F, --field-separator=STRING
field separator for unaligned output (default: "|")
-H, --html HTML table output mode
-P, --pset=VAR[=ARG] set printing option VAR to ARG (see \pset command)
-R, --record-separator=STRING
record separator for unaligned output (default: newline)
-t, --tuples-only print rows only
-T, --table-attr=TEXT set HTML table tag attributes (e.g., width, border)
-x, --expanded turn on expanded table output
-z, --field-separator-zero
set field separator for unaligned output to zero byte
-0, --record-separator-zero
set record separator for unaligned output to zero byte
Connection options:
-h, --host=HOSTNAME database server host or socket directory (default: "local socket")
-p, --port=PORT database server port (default: "54321")
-U, --username=USERNAME database user name (default: "kingbase")
-w, --no-password never prompt for password
-W, --password force password prompt (should happen automatically)
For more information, type "\?" (for internal commands) or "\help" (for SQL
commands) from within ksql, or consult the ksql section in the Kingbase
documentation.
Report bugs to <kingbase-bugs@kingbase.com.cn>.
3.2 连接数据库
[kingbase@node1 data]$ ksql -U system test
ksql (V8.0)
Type "help" for help.
test=# \l
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
-----------+--------+----------+-------------+-------------+-------------------
security | system | UTF8 | zh_CN.UTF-8 | zh_CN.UTF-8 |
template0 | system | UTF8 | zh_CN.UTF-8 | zh_CN.UTF-8 | =c/system +
| | | | | system=CTc/system
template1 | system | UTF8 | zh_CN.UTF-8 | zh_CN.UTF-8 | =c/system +
| | | | | system=CTc/system
test | system | UTF8 | zh_CN.UTF-8 | zh_CN.UTF-8 |
(4 rows)
3.3 创建测试数据
test=# create database prod;
CREATE DATABASE
test=# \c prod
You are now connected to database "prod" as user "system".
prod=# create table t1 (id int ,name varchar(10));
CREATE TABLE
prod=# insert into t1 values (10,'tom'),(20,'jerry');
INSERT 0 2
prod=# \d t1
Table "public.t1"
Column | Type | Collation | Nullable | Default
--------+----------------------------+-----------+----------+---------
id | integer | | |
name | character varying(10 char) | | |
prod=# select * from t1;
id | name
----+-------
10 | tom
20 | jerry
(2 rows)
四、总结
KingbaseES数据库服务启动比较简单,对于Linux系统可以通过sys_ctl工具启动数据库服务;对于Windows环境可以通过Windows服务启动,也可以通过Command界面通过sys_ctl启动。
