當前平臺:centos5.8, x86_64
1. 下載地址:http://spiderformysql.com/index.html,
當前下載的文件名:mysql-5.5.34-spider-3.2-vp-1.1-hs-1.2-q4m-0.95.tgz (源碼安裝)
2. 安裝cmake軟件,如果可以直接用yum install cmake (不要裝與系統版本不適合版本避免兼容性和編譯時的一些報錯)
3.解壓後安裝
#tar -zxvf mysql-5.5.34-spider-3.2-vp-1.1-hs-1.2-q4m-0.95.tgz
#cd mysql-5.5.34-spider-3.2-vp-1.1-hs-1.2-q4m-0.95
# cmake .
# make
# make install
#中間可能會報一些由於缺少安裝gcc的包而引起的報錯。yum install gcc gcc-c
#正常編譯通過的結尾部份:
-- Running cmake version 2.6.4
-- MySQL 5.5.34
-- Packaging as: mysql-5.5.34-Linux-x86_64
-- Configuring done
-- Generating done
-- Build files have been written to: /root/mysql-5.5.34-spider-3.2-vp-1.1-hs-1.2-q4m-0.95
#如果出一些類似 的警告問題，證明編譯非正常結束，建議先修復，如以下：
-- Performing Test HAVE_PEERCRED
-- Performing Test HAVE_PEERCRED - Success
Warning: Bison executable not found in PATH
-- Configuring done
-- Generating done
-- Build files have been written to: /root/mysql-5.5.34-spider-3.2-vp-1.1-hs-1.2-q4m-0.95
==>解決方式yum install bison
4.啓動前先初始化環境:
#根據實際情況調整
/usr/local/mysql/scripts/mysql_install_db \
--defaults-file=/etc/my.cnf \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data \
--user=mysql
5.選擇其中一種方式啓動(這裏mysql.server)
修改mysql.server裏邊的變量
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
#修改完成後./mysql.server start啓動庫
6.執行bin目錄下的mysql 連接庫和創建spider引擎
mysql -uroot -p
source /usr/local/mysql/share/install_spider.sql
mysql> source /usr/local/mysql/share/install_spider.sql

==>解決辦法 ：修改/etc/my.cnf裏邊的變量: thread_stack=256000,重新執行腳本一次

示例 ：當前3臺主機，1臺建spider引擎（ip:192.168.56.51)，另兩臺裏邊包含的分區表所在庫，ip分別爲192.168.56.52和53

（1）、52，53機器上分別建立表tbl_a
mysql> show create table tbl_a\G
*************************** 1. row ***************************
Table: tbl_a
Create Table: CREATE TABLE `tbl_a` (
`col_a` int(11) NOT NULL,
`col_b` varchar(20) DEFAULT NULL,
`col_c` int(11) NOT NULL,
PRIMARY KEY (`col_a`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1
1 row in set (0.05 sec)
(2)、51機器
CREATE SERVER backend1
FOREIGN DATA WRAPPER mysql
OPTIONS(
HOST '192.168.56.52',
DATABASE 'test',
USER 'root',
PASSWORD '123456789',
PORT 3306
);
CREATE SERVER backend2
FOREIGN DATA WRAPPER mysql
OPTIONS(
HOST '192.168.56.53',
DATABASE 'test',
USER 'root',
PASSWORD '123456789',
PORT 3306
);
create table test.tbl_a(
col_a int not null,
col_b varchar(20),
col_c int not null,
primary key(col_a)
)engine=spider connection='wrapper "mysql", user "root", password "123456789",table "tbl_a", port "3306"'
partition by key(col_a)
(partition pt1 comment='srv"backend1"' engine=spider, partition pt2 comment='srv"backend2"' engine=spider);
mysql> select * from tbl_a;
Empty set (0.12 sec)
mysql> insert into tbl_a values(1,'a',1);

mysql> commit;
Query OK, 0 rows affected (0.00 sec)

mysql> commit;

mysql> select * from tbl_a;
+-------+-------+-------+
| col_a | col_b | col_c |
+-------+-------+-------+
| 1 | a | 1 |
| 3 | a | 3 |
| 2 | a | 2 |
+-------+-------+-------+
3 rows in set (0.03 sec)
(3)、52，53的機器上分別查詢:
52機器:
mysql> select * from tbl_a;
+-------+-------+-------+
| col_a | col_b | col_c |
+-------+-------+-------+
| 1 | a | 1 |
| 3 | a | 3 |
+-------+-------+-------+
53機器:
mysql> select * from tbl_a;
+-------+-------+-------+
| col_a | col_b | col_c |
+-------+-------+-------+
| 2 | a | 2 |
+-------+-------+-------+
1 row in set (0.00 sec)
小結：證明從表51上插入的行已按分區方式自動分散到兩個分區。
