一、準備工作

1. Mycat全局自增實現思路

• 在任意節點創建mycat數據庫
• 將/app/mycat/conf/dbseq.sql文件中的數據導入到mycat數據庫中
• 修改schema.xml文件添加主機節點和數據節點，如果主機節點已經存在，可以不添加
• 修改server.xml設置增增ID生成類型為數據庫形式
• 修改 sequence_db_conf.properties文件，設置那些邏輯表需要自增ID和數據節點的名稱
• 給mycat數據庫中的MYCAT_SEQUENCE 表插入一條數據，設置定增屬性
• 修改schema.xml文件，設置給哪個邏輯表自用自增ID
• 賦予mycat用戶操作函數的權限
• 重新啟動mycat
• 數據清理
• 批量插入數據，查看order_id 是否重復

2. 創建mycat數據庫

在任意節點，創建mycat數據庫，這里演示在node1節點創建mycat數據庫

# 登錄node1節點的mysql mysql -uroot -p123456# 查看數據庫列表 mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | imooc_db | | mysql | | performance_schema | | sys | +--------------------+ 5 rows in set (0.01 sec)# 創建數據庫 create database mycat;mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | imooc_db | | mycat | | mysql | | performance_schema | | sys | +--------------------+ 6 rows in set (0.00 sec)

注：其他節點創建mycat數據庫一樣

3. 導入初始化腳本

將dbseq.sql導入MyCat數據庫中

# 進入mycat的conf目錄 cd /app/mycat/conf# 初始化表結構腳本 mysql -uroot -p mycat < dbseq.sql

4. 登錄驗證

# 登錄mycat數據庫 mysql -uroot -p123456# 使用mycat數據庫 use mycat;# 查看初始化腳本后的數據庫有哪些對象 show tables;# 查看MYCAT_SEQUENCE表中數據 select * from MYCAT_SEQUENCE;可以看出設置了全局id 1 自增1 mysql> use mycat; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -ADatabase changed mysql> show tables; +-----------------+ | Tables_in_mycat | +-----------------+ | MYCAT_SEQUENCE | +-----------------+ 1 row in set (0.00 sec)mysql> select * from MYCAT_SEQUENCE; +--------+---------------+-----------+ | name | current_value | increment | +--------+---------------+-----------+ | GLOBAL | 1 | 1 | +--------+---------------+-----------+ 1 row in set (0.00 sec)

二、配置文件修改

2.1. server.xml配置

cd /app/mycat/conf/ vim server.xml <!-- 0-以本地文件生成序列號 1-以數據庫形式 2-時間戳序列 3-以zookeeper形式生成自增序列 --> # 將此屬性修改為1 ，1代表從數據庫中讀取 # 告訴mycat我是石勇數據庫讀取的方式生成全局自增id <property name="sequnceHandlerType">1</property>

2.2. 添加數據節點

在schema.xml文件中，添加數據主機節點

<dataHost name="mysql92101" maxCon="1000" minCon="10" balance="3" writeType="0" dbType="mysql" dbDriver="native" switchType="1"><heartbeat>select user()</heartbeat><writeHost host="192.168.92.101" url="192.168.92.101:3306" user="im_mycat" password="123456"></writeHost></dataHost>

添加數據節點

<dataNode name="mycat" dataHost="mysql92101" database="mycat" />

注：如果mycat數據庫和分片的某一個數據庫節點在一個mysql中，添加dohost節點這一步可以省略

2.3. 驗證im_mycat權限

# 登錄mysql mysql -uroot -p123456# 使用mysql數據庫 mysql> use mysql; Database changed mysql> select user,host from user; +---------------+--------------+ | user | host | +---------------+--------------+ | root | % | | im_mycat | 192.168.92.% | | im_repl | 192.168.92.% | | mysql.session | localhost | | mysql.sys | localhost | +---------------+--------------+ 5 rows in set (0.00 sec)# 查看im_mycat用戶權限 mysql> show grants for im_mycat@'192.168.92.%'; +-----------------------------------------------------------------------------------+ | Grants for im_mycat@192.168.92.% | +-----------------------------------------------------------------------------------+ | GRANT SELECT, INSERT, UPDATE, DELETE, EXECUTE ON *.* TO 'im_mycat'@'192.168.92.%' | +-----------------------------------------------------------------------------------+ 1 row in set (0.00 sec)

2.4. 配置數據節點和邏輯表明

sequence_db_conf.properties

• 數據節點
• 自增表和mycay數據庫所在數據節點名稱

# 指定表、函數所在的數據節點 vim sequence_db_conf.propertiesGLOBAL=mycat # ORDER_MASTER表所在的數據節點 ORDER_MASTER=mycat

2.5. 設置自增屬性

最后在mycat數據庫中，給mycat_sequence 插入一條數據，設置自增屬性
insert into mycat_sequence values (‘order_key’,1,1);
#再次查看

# 登錄mysql mysql -uroot -p123456# 使用mycat數據庫 use mycat;# 查詢MYCAT_SEQUENCE select * from MYCAT_SEQUENCE;# 給MYCAT_SEQUENCE 插入一條數據，設置定增屬性 insert into MYCAT_SEQUENCE VALUES ('ORDER_MASTER',1,1);# 再次查看 select * from MYCAT_SEQUENCE;

執行記錄：

mysql> use mycat Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -ADatabase changed mysql> select * from MYCAT_SEQUENCE; +--------+---------------+-----------+ | name | current_value | increment | +--------+---------------+-----------+ | GLOBAL | 1 | 1 | +--------+---------------+-----------+ 1 row in set (0.00 sec)mysql> insert into MYCAT_SEQUENCE VALUES ('ORDER_MASTER',1,1); Query OK, 1 row affected (0.01 sec)mysql> select * from MYCAT_SEQUENCE; +--------------+---------------+-----------+ | name | current_value | increment | +--------------+---------------+-----------+ | GLOBAL | 1 | 1 | | ORDER_MASTER | 1 | 1 | +--------------+---------------+-----------+ 2 rows in set (0.00 sec)mysql>

2.6. 開啟自增屬性

在ORDER_MASTER 的邏輯表中添加autoIncrement="true"屬性
在邏輯表(ORDER_MASTER )中,添加autoIncrement="true"屬性

cd /app/mycat/confvim schema.xml <table name="order_master" primaryKey="order_id" dataNode="ordb01,ordb02,ordb03,ordb04" rule="order_master" autoIncrement="true"/>

2.7. 賦予權限

賦予權限im_mycat用戶執行函數的權限

mysql -uroot -p123456 use mysql; show grants for im_mycat@'192.168.92.%';# 賦予權限`im_mycat`用戶執行函數的權限 grant execute on *.* to 'im_mycat'@'192.168.92.%';show grants for im_mycat@'192.168.92.%';

執行日志

mysql> use mysql; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -ADatabase changed mysql> show grants for im_mycat@'192.168.92.%'; +-----------------------------------------------------------------------------------+ | Grants for im_mycat@192.168.92.% | +-----------------------------------------------------------------------------------+ | GRANT SELECT, INSERT, UPDATE, DELETE, EXECUTE ON *.* TO 'im_mycat'@'192.168.92.%' | +-----------------------------------------------------------------------------------+ 1 row in set (0.00 sec) mysql> grant execute on *.* to 'im_mycat'@'192.168.92.%'; Query OK, 0 rows affected (0.01 sec)mysql> show grants for im_mycat@'192.168.92.%'; +-----------------------------------------------------------------------------------+ | Grants for im_mycat@192.168.92.% | +-----------------------------------------------------------------------------------+ | GRANT SELECT, INSERT, UPDATE, DELETE, EXECUTE ON *.* TO 'im_mycat'@'192.168.92.%' | +-----------------------------------------------------------------------------------+ 1 row in set (0.00 sec)mysql>

三、測試驗證

3.1. 重啟mycat

重新啟動mycat

mycat stopmycat start

3.2. 數據清理

mysql -uapp_imooc -p123456 -h192.168.92.101 -P8066 use imooc_db; delete from order_master;

3.3. 批量插入數據

INSERT INTO `order_master` (order_sn,customer_id,shipping_user,province,city,district,address,payment_method,order_money,district_money,shipping_money,payment_money,shipping_comp_name,shipping_sn,create_time,shipping_time,pay_time,receive_time,order_status,order_point,invoice_title,modified_time) VALUES (1, 1, '雨昕', 1, 1, 1, '北京', 1, 10.00, 0.00, 0.00, 0.00, NULL, NULL, '2021-07-11 20:20:25', NULL, '2021-07-11 20:18:55', '2021-07-11 20:18:59', 0, 0, NULL, '2021-07-11 20:20:25'); INSERT INTO `order_master` (order_sn,customer_id,shipping_user,province,city,district,address,payment_method,order_money,district_money,shipping_money,payment_money,shipping_comp_name,shipping_sn,create_time,shipping_time,pay_time,receive_time,order_status,order_point,invoice_title,modified_time) VALUES (2, 2, '雨昕', 1, 1, 1, '北京', 1, 10.00, 0.00, 0.00, 0.00, NULL, NULL, '2021-07-11 20:20:25', NULL, '2021-07-11 20:18:55', '2021-07-11 20:18:59', 0, 0, NULL, '2021-07-11 20:20:25'); INSERT INTO `order_master` (order_sn,customer_id,shipping_user,province,city,district,address,payment_method,order_money,district_money,shipping_money,payment_money,shipping_comp_name,shipping_sn,create_time,shipping_time,pay_time,receive_time,order_status,order_point,invoice_title,modified_time) VALUES (1, 3, '雨昕', 1, 1, 1, '北京', 1, 10.00, 0.00, 0.00, 0.00, NULL, NULL, '2021-07-11 20:20:25', NULL, '2021-07-11 20:18:55', '2021-07-11 20:18:59', 0, 0, NULL, '2021-07-11 20:20:25'); INSERT INTO `order_master` (order_sn,customer_id,shipping_user,province,city,district,address,payment_method,order_money,district_money,shipping_money,payment_money,shipping_comp_name,shipping_sn,create_time,shipping_time,pay_time,receive_time,order_status,order_point,invoice_title,modified_time) VALUES (1, 4, '雨昕', 1, 1, 1, '北京', 1, 10.00, 0.00, 0.00, 0.00, NULL, NULL, '2021-07-11 20:20:25', NULL, '2021-07-11 20:18:55', '2021-07-11 20:18:59', 0, 0, NULL, '2021-07-11 20:20:25'); INSERT INTO `order_master` (order_sn,customer_id,shipping_user,province,city,district,address,payment_method,order_money,district_money,shipping_money,payment_money,shipping_comp_name,shipping_sn,create_time,shipping_time,pay_time,receive_time,order_status,order_point,invoice_title,modified_time) VALUES (1, 5, '雨昕', 1, 1, 1, '北京', 1, 10.00, 0.00, 0.00, 0.00, NULL, NULL, '2021-07-11 20:20:25', NULL, '2021-07-11 20:18:55', '2021-07-11 20:18:59', 0, 0, NULL, '2021-07-11 20:20:25'); INSERT INTO `order_master` (order_sn,customer_id,shipping_user,province,city,district,address,payment_method,order_money,district_money,shipping_money,payment_money,shipping_comp_name,shipping_sn,create_time,shipping_time,pay_time,receive_time,order_status,order_point,invoice_title,modified_time) VALUES (1, 6, '雨昕', 1, 1, 1, '北京', 1, 10.00, 0.00, 0.00, 0.00, NULL, NULL, '2021-07-11 20:20:25', NULL, '2021-07-11 20:18:55', '2021-07-11 20:18:59', 0, 0, NULL, '2021-07-11 20:20:25'); INSERT INTO `order_master` (order_sn,customer_id,shipping_user,province,city,district,address,payment_method,order_money,district_money,shipping_money,payment_money,shipping_comp_name,shipping_sn,create_time,shipping_time,pay_time,receive_time,order_status,order_point,invoice_title,modified_time) VALUES (1, 7, '雨昕', 1, 1, 1, '北京', 1, 10.00, 0.00, 0.00, 0.00, NULL, NULL, '2021-07-11 20:20:25', NULL, '2021-07-11 20:18:55', '2021-07-11 20:18:59', 0, 0, NULL, '2021-07-11 20:20:25'); INSERT INTO `order_master` (order_sn,customer_id,shipping_user,province,city,district,address,payment_method,order_money,district_money,shipping_money,payment_money,shipping_comp_name,shipping_sn,create_time,shipping_time,pay_time,receive_time,order_status,order_point,invoice_title,modified_time) VALUES (1, 8, '雨昕', 1, 1, 1, '北京', 1, 10.00, 0.00, 0.00, 0.00, NULL, NULL, '2021-07-11 20:20:25', NULL, '2021-07-11 20:18:55', '2021-07-11 20:18:59', 0, 0, NULL, '2021-07-11 20:20:25'); INSERT INTO `order_master` (order_sn,customer_id,shipping_user,province,city,district,address,payment_method,order_money,district_money,shipping_money,payment_money,shipping_comp_name,shipping_sn,create_time,shipping_time,pay_time,receive_time,order_status,order_point,invoice_title,modified_time) VALUES (1, 9, '雨昕', 1, 1, 1, '北京', 1, 10.00, 0.00, 0.00, 0.00, NULL, NULL, '2021-07-11 20:20:25', NULL, '2021-07-11 20:18:55', '2021-07-11 20:18:59', 0, 0, NULL, '2021-07-11 20:20:25'); INSERT INTO `order_master` (order_sn,customer_id,shipping_user,province,city,district,address,payment_method,order_money,district_money,shipping_money,payment_money,shipping_comp_name,shipping_sn,create_time,shipping_time,pay_time,receive_time,order_status,order_point,invoice_title,modified_time) VALUES ( 1,10, '雨昕', 1, 1, 1, '北京', 1, 10.00, 0.00, 0.00, 0.00, NULL, NULL, '2021-07-11 20:20:25', NULL, '2021-07-11 20:18:55', '2021-07-11 20:18:59', 0, 0, NULL, '2021-07-11 20:20:25');

3.4. 查看數據

mysql> select customer_id,order_sn,order_id from order_master order by order_id; +-------------+----------+----------+ | customer_id | order_sn | order_id | +-------------+----------+----------+ | 1 | 1 | 2 | | 2 | 2 | 3 | | 3 | 1 | 4 | | 4 | 1 | 5 | | 5 | 1 | 6 | | 6 | 1 | 7 | | 7 | 1 | 8 | | 8 | 1 | 9 | | 9 | 1 | 10 | | 10 | 1 | 11 | +-------------+----------+----------+ 10 rows in set (0.03 sec)
