楼主

一、安装
1、下载 mysql-5.1.54.tar.gz 解压至 /root/mysql/mysql-5.1.54 目录
2、下载 ahiguti-HandlerSocket-Plugin-for-MySQL-1.0.6-94-g98b14c3.tar.gz 解压至 /root/mysql/ahiguti-HandlerSocket-Plugin-for-MySQL-98b14c3 目录
3、以动态编译的形式编译安装 mysql 到 /usr/local/mysql5.1
4、编译 HandlerSocket 插件，在 /root/mysql/ahiguti-HandlerSocket-Plugin-for-MySQL-98b14c3 目录

# ./autogen.sh
# ./configure --with-mysql-source=/root/mysql/mysql-5.1.54 --with-mysql-bindir=/usr/local/mysql5.1/bin --with-mysql-plugindir=/usr/local/mysql5.1/lib/mysql/plugin

with-mysql-source 表示MySQL源代码目录，with-mysql-bindir 表示MySQL二进制可执行文件目录（也就是 mysql_config 所在目录），with-mysql-plugindir 表示MySQL插件目录
如果不清楚这个目录在哪，可以按如下方法查询：

编译和安装

# make && make install

二、配置 MySQL

# vi /etc/my.cnf
[mysqld]
loose_handlersocket_port = 9998
# the port number to bind to (for read requests)
loose_handlersocket_port_wr = 9999
# the port number to bind to (for write requests)
loose_handlersocket_threads = 16
# the number of worker threads (for read requests)
loose_handlersocket_threads_wr = 1
# the number of worker threads (for write requests)
open_files_limit = 65535
# to allow handlersocket accept many concurren connections, make open_files_limit as large as possible.

激活HandlerSocket插件，在客户端命令执行

mysql> install plugin handlersocket soname 'handlersocket.so';

查看 handlersocket 进程

查看系统进程占用的端口

# lsof -i :9998
COMMAND  PID  USER   FD   TYPE DEVICE SIZE NODE NAME
mysqld  2731 mysql   11u  IPv4 571386       TCP *:9998 (LISTEN)
# lsof -i :9999
COMMAND  PID  USER   FD   TYPE DEVICE SIZE NODE NAME
mysqld  2731 mysql   29u  IPv4 571403       TCP *:9999 (LISTEN)

三、测试使用

在数据库 test 创建测试表

CREATE TABLE `user` (
`user_id` INT(10) UNSIGNED NOT NULL,
`user_name` VARCHAR(50) DEFAULT NULL,
`user_email` VARCHAR(255) DEFAULT NULL,
`created` DATETIME DEFAULT NULL,
PRIMARY KEY (`user_id`),
KEY `INDEX_01` (`user_name`)
) ENGINE=INNODB

插入测试数据

INSERT INTO USER VALUES(1, "John", "john@test.com", CURRENT_TIMESTAMP);
INSERT INTO USER VALUES(2, "Kevin", "Kevin@test.com", CURRENT_TIMESTAMP);
INSERT INTO USER VALUES(3, "Dino", "Dino@test.com", CURRENT_TIMESTAMP);

编译 Perl 客户端，在 /root/mysql/ahiguti-HandlerSocket-Plugin-for-MySQL-98b14c3 目录执行

# ./autogen.sh
# ./configure --disable-handlersocket-server
# make && make install
# cd perl-Net-HandlerSocket
# perl Makefile.PL
# make && make install

perl 程序文件：

Php代码

#!/usr/bin/perl
use strict;
use warnings;
use Net::HandlerSocket;
#1. establishing a connection
my $args = { host => 'localhost', port => 9998 };
my $hs = new Net::HandlerSocket($args);
#2. initializing an index so that we can use in main logics.
# MySQL tables will be opened here (if not opened)
my $res = $hs->open_index(0, 'test', 'user', 'INDEX_01', 'user_name,user_email,created');
die $hs->get_error() if $res != 0;
#3. main logic
#fetching rows by id
#execute_single (index id, cond, cond value, max rows, offset)
$res = $hs->execute_single(0, '=', [ 'kevin' ], 1, 0);
die $hs->get_error() if $res->[0] != 0;
shift(@$res);
for (my $row = 0; $row < 1; ++$row) {
      my $user_name= $res->[$row + 0];
      my $user_email= $res->[$row + 1];
      my $created= $res->[$row + 2];
      print "$user_name\t$user_email\t$created\n";
}
#4. closing the connection
$hs->close();

下载 hs4j-0.1 软件包。
Java 程序文件：

Java代码

import java.sql.ResultSet;
import com.google.code.hs4j.HSClient;
import com.google.code.hs4j.HSClientBuilder;
import com.google.code.hs4j.IndexSession;
import com.google.code.hs4j.impl.HSClientBuilderImpl;
public class TestNoSQL {
      public static void main(String[] args) throws Exception {
            HSClientBuilder hscb = new HSClientBuilderImpl();
            hscb.setServerAddress("10.10.10.2", 9999);
            HSClient hsc = hscb.build();
      IndexSession is = hsc.openIndexSession(1,"test", "user", "INDEX_01", new String[]{"user_name","user_email","created"});
            // 插入
      is.insert(new String[]{"ezerg", "ezerg@126.com", "2011-10-12 13:04:33"});
      final String[] keys = { "ezerg"};
            // 查询
            ResultSet rs = is.find(keys);
            while(rs.next()) {
                  System.out.println("name="+rs.getString(1));
                  System.out.println("email="+rs.getString(2));
            }
            // 删除
            // is.delete(keys);
            // 更新
      // is.update(keys, new String[] { "ezerg", "ezerg@163.com", "2011-10-12 13:04:33" }, FindOperator.EQ);
            // 关闭连接
            hsc.shutdown();
      }
}
