spider存储引擎

1.spider 安装

1.1.MariaDB 安装

1.1.1 下载MariaDB wget https://mirrors.tuna.tsinghua.edu.cn/mariadb//mariadb-10.3.16/bintar-linux-x86_64/mariadb-10.3.16-linux-x86_64.tar.gz

https://mariadb.com/downloads/

1.1.2 解压安装

[root@localhost:/usr/local]#tar -zxvf mariadb-10.3.16-linux-x86_64.tar.gz -C /usr/local/

[root@localhost:/usr/local]#ln -s mariadb-10.3.16-linux-x86_64 mariadb

[root@localhost:/usr/local]#cd mariadb

[root@localhost:/usr/local/mariadb]#cp /etc/my.cnf /etc/my_3320.cnf ####生成my.cnf文件与原生mysql差不多，有个别参数不存在。

[root@localhost:/usr/local/mariadb]#./scripts/mysql_install_db --defaults-file=/etc/my_3320.cnf --basedir=/usr/local/mariadb/

[root@localhost:/usr/local/mariadb]#chown -R mysql:mysql /data/mysql_3320/

[root@localhost:/usr/local/mariadb]#/usr/local/mariadb-10.3.16-linux-x86_64/bin/mysqld_safe --defaults-file=/etc/my_3320.cnf &

1.2.安装spider 引擎

[root@localhost:/usr/local/mariadb]#mysql -uroot -p < /usr/local/mariadb/share/install_spider.sql

root@localhost 19:46: [(none)]> select * from information_schema.engines where engine='SPIDER';

2.spider的使用实战

2.1 创建spider引擎表方法1

#mysql node1

CREATE TABLE s(

id INT NOT NULL AUTO_INCREMENT,

code VARCHAR(10),

PRIMARY KEY(id));

#spider node

CREATE TABLE s(

id INT NOT NULL AUTO_INCREMENT,

code VARCHAR(10),

PRIMARY KEY(id)

)

ENGINE=SPIDER COMMENT 'host "10.204.10.20", user "work", password "123456", port "3306", database "lucky_order"';

2.2 创建spider引擎表方法2

#创建spider到后端DB server的配置

CREATE SERVER lucky_test1 FOREIGN DATA WRAPPER mysql OPTIONS (

HOST '10.212.22.22',

DATABASE 'lucky_test1',

USER 'admintools',

PASSWORD '111111',

PORT 3306

);

CREATE SERVER lucky_test2 FOREIGN DATA WRAPPER mysql OPTIONS (

HOST '10.204.28.1',

DATABASE 'lucky_test2',

USER 'admintools',

PASSWORD '111111',

PORT 3336

);

或者直接插入mysql.servers表

INSERT INTO mysql.servers(Server_name,HOST,Db,Username,PASSWORD,PORT,SOCKET,WRAPPER,OWNER)

VALUES ('lucky_test1','10.212.22.22','lucky_test1','work','111111',3306,'','mysql','');

INSERT INTO mysql.servers(Server_name,HOST,Db,Username,PASSWORD,PORT,SOCKET,WRAPPER,OWNER)

VALUES ('lucky_test2','10.204.55.72','lucky_test2','work','111111',3306,'','mysql','');

#mysql node1

CREATE TABLE lucky_test1.sbtest1 (

id int(10) unsigned NOT NULL AUTO_INCREMENT,

k int(10) unsigned NOT NULL DEFAULT '0',

c char(120) NOT NULL DEFAULT '',

pad char(60) NOT NULL DEFAULT '',

PRIMARY KEY (id),

KEY k (k)

) ENGINE=InnoDB;

#mysql node2

CREATE TABLE lucky_test2.sbtest2 (

id int(10) unsigned NOT NULL AUTO_INCREMENT,

k int(10) unsigned NOT NULL DEFAULT '0',

c char(120) NOT NULL DEFAULT '',

pad char(60) NOT NULL DEFAULT '',

PRIMARY KEY (id),

KEY k (k)

) ENGINE=InnoDB;

#spider node

CREATE TABLE test.sbtest1

(

id int(10) unsigned NOT NULL AUTO_INCREMENT,

k int(10) unsigned NOT NULL DEFAULT '0',

c char(120) NOT NULL DEFAULT '',

pad char(60) NOT NULL DEFAULT '',

PRIMARY KEY (id),

KEY k (k)

) ENGINE=spider COMMENT='wrapper "mysql",srv "lucky_test1"';

CREATE TABLE test.sbtest2

(

id int(10) unsigned NOT NULL AUTO_INCREMENT,

k int(10) unsigned NOT NULL DEFAULT '0',

c char(120) NOT NULL DEFAULT '',

pad char(60) NOT NULL DEFAULT '',

PRIMARY KEY (id),

KEY k (k)

) ENGINE=spider COMMENT='wrapper "mysql",srv "lucky_test2"';

SELECT * FROM sbtest1 a JOIN sbtest2 b ON a.id=b.id LIMIT 10;

DROP SERVER lucky_test0;

DROP TABLE test.sbtest1; drop spider上的表，不会drop后端DB server上的表。

2.3 创建hash分区表

CREATE TABLE sbtest (

id INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,

k INT(10) UNSIGNED NOT NULL DEFAULT '0',

c CHAR(120) NOT NULL DEFAULT '',

pad CHAR(60) NOT NULL DEFAULT '',

PRIMARY KEY (id),

KEY k (k)

) ENGINE=SPIDER DEFAULT CHARSET=utf8 COMMENT='wrapper "mysql", table "sbtest1"'

PARTITION BY HASH (id)

( PARTITION pt1 COMMENT='wrapper "mysql",srv "lucky_test1"',

PARTITION pt2 COMMENT='wrapper "mysql",srv "lucky_test0"') ;

2.4 创建range分区表

CREATE TABLE sbtest_range (

id INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,

k INT(10) UNSIGNED NOT NULL DEFAULT '0',

c CHAR(120) NOT NULL DEFAULT '',

pad CHAR(60) NOT NULL DEFAULT '',

PRIMARY KEY (id),

KEY k (k)

) ENGINE=SPIDER DEFAULT CHARSET=utf8 COMMENT='wrapper "mysql", table "sbtest1"'

PARTITION BY range columns (id)

( PARTITION pt1 values less than (100000) COMMENT='wrapper "mysql",srv "lucky_test1"',

PARTITION pt2 values less than (200000) COMMENT='wrapper "mysql",srv "lucky_test0"') ;

2.5 创建list分区表

CREATE TABLE sbtest_list (

id INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,

k INT(10) UNSIGNED NOT NULL DEFAULT '0',

c CHAR(120) NOT NULL DEFAULT '',

pad CHAR(60) NOT NULL DEFAULT '',

PRIMARY KEY (id),

KEY k (k)

) ENGINE=SPIDER DEFAULT CHARSET=utf8 COMMENT='wrapper "mysql", table "sbtest1"'

PARTITION BY list columns (id)

( PARTITION pt1 values in (1,3,5,7,9) COMMENT='wrapper "mysql",srv "lucky_test1"',

PARTITION pt2 values in (2,4,6,8,10) COMMENT='wrapper "mysql",srv "lucky_test0"') ;
