HandlerSocket是一個MySQL插件,它允許在不經過SQL解析器的情況下直接訪問MySQL數據庫。下面是安裝和使用HandlerSocket的步驟:
安裝HandlerSocket插件:
cd HandlerSocket-Plugin-for-MySQL-<version>
make && sudo make install
配置MySQL服務器以啟用HandlerSocket插件:
sudo vi /etc/mysql/my.cnf
[mysqld]
...
# HandlerSocket插件配置
loose_handlersocket_port = 9998
loose_handlersocket_port_wr = 9999
loose_handlersocket_threads = 16
loose_handlersocket_threads_wr = 1
sudo service mysql restart
使用HandlerSocket插件:
mysql -u <username> -p
CREATE DATABASE <database_name>;
USE <database_name>;
CREATE TABLE <table_name> (...) ENGINE=HANDLER;
INSERT INTO <table_name> (...) VALUES (...);
SELECT * FROM <table_name> WHERE <condition>;
UPDATE <table_name> SET <column_name> = <new_value> WHERE <condition>;
INSERT INTO <table_name> (...) VALUES (...);
DELETE FROM <table_name> WHERE <condition>;
注意:HandlerSocket插件的使用方式與傳統的SQL查詢略有不同。你可以在插件的文檔中找到更多詳細的使用說明和示例:https://github.com/ahiguti/HandlerSocket-Plugin-for-MySQL/blob/master/docs-en.md
