oscommerce的與MySQL

Original post: http://anothermysqldba.blogspot.com/2013/05/oscommerce-mysql.html

它已經一段時間，因為我看著oscommerce的軟件包。這是一個偉大的平台，為構建一個網上商店在線。

然而，當他們問，如果你是上面的“MYSQL \ V5”或低於它開始讓我緊張。很顯然，我並不孤單InnoDB的存儲引擎的選擇應該是與關注。

所以，我決定挖多一點......

我假設您運行的是更多更新的MySQL，或者最起碼，你打算做很快。

如果您運行的是一家店，客戶數據，然後在你選擇的數據庫，穩定性應該是一個重要的因素。我想更新這些InnoDB的輕鬆。


>SELECT

CONCAT('ALTER TABLE ',TABLE_SCHEMA,'.',TABLE_NAME,' ENGINE=InnoDB;') as query
INTO OUTFILE '/tmp/update_oscommerce.sql'
FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA NOT IN ('mysql', 'INFORMATION_SCHEMA') AND ENGINE IS NOT NULL AND TABLE_SCHEMA = 'oscommerce'
GROUP BY TABLE_SCHEMA, TABLE_NAME;

此查詢創建一個簡單的ALTER TABLE所有osCommerce的表。如果您已設置你的表前綴與其他表到數據庫中，你可以調整相應的查詢。


mysql -p < /tmp/update_oscommerce.sql

所以沒有工作？是，你必須要知道，你會看到一個不同的大小和索引大小。

因為我正好有innodb_file_per_table的設置，我會得到什麼。IBD文件每桌當然也是如此。

管理網站，以及購物車測試快速測試顯示一切工作得很好，到目前為止。一個簡單的辦法，這將取決於表的大小，速度有多快，它為你做。這個例子是一個全新的安裝。

如果你已經複製，然後能夠關閉的奴隸和更新的表上的奴隸，首先將是一個良好的開端。然後旋轉高手，除非你能承受的停機時間。

如果你沒有複製.. 那麼你應該看看它。你也應該，我希望你做什麼，它備份至少每天。

NoSQL :: PHP :: MEMCACHE :: INNODB :: MySQL

Original Post: http://anothermysqldba.blogspot.com/2013/04/nosql-php-memcache-innodb-mysql.html

现在的MySQL 5.6已经出了一小会儿， Percona的5.6 ，在写这篇的时候，阿尔法，我们都将开始看起来更涉及到MySQL的NoSQL解决方案。（我会继续关注和MariaDB的在这方面做的）。但无论如何... 因为开发人员和管理人员继续好奇的NoSQL可以提供什么....

这仅仅是给予了很高的水平作为一个NoSQL解决方案使用Memcache的概述，并保持MySQL的InnoDB数据库和数据圆通。

虽然这个博客是不是第一个关于这个主题，我希望这几件事情连在一起，对一些人来说。

良好的读取和引用在这里：

# php --version

PHP 5.4.14 (cli) (built: Apr 27 2013 14:22:04)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies

否则我的PHP安装也有这个....


more /etc/php.d/memcache.ini

; ----- Options to use the memcache session handler
; Use memcache as a session handler
session.save_handler=memcache
; Defines a comma separated of server urls to use for session storage
session.save_path="tcp://localhost:11211"

首先激活插件...

mysql> install plugin daemon_memcached soname "libmemcached.so";

创建一个数据库，所以我们不只是使用标准试验Db和demo_test的所有其他的例子中使用。只是为了显示它不只是锁定。


CREATE DATABASE nosql_mysql_innodb_memcache;
use nosql_mysql_innodb_memcache;

CREATE TABLE nosql_mysql (
`demo_key` VARCHAR(32),
`demo_value` VARCHAR(1024),
`demo_flag` INT,
`demo_cas` BIGINT UNSIGNED,
`demo_expire` INT,
primary key(demo_key)
)
ENGINE = INNODB;

use innodb_memcache;

INSERT INTO containers VALUES ('DEMO','nosql_mysql_innodb_memcache','nosql_mysql','demo_key','demo_value','demo_flag','demo_cas','demo_expire','PRIMARY');


select * from containers\G
*************************** 1. row ***************************
name: DEMO
db_schema: nosql_mysql_innodb_memcache
db_table: nosql_mysql
key_columns: demo_key
value_columns: demo_value
flags: demo_flag
cas_column: demo_cas
expire_time_column: demo_expire
unique_idx_name_on_key: PRIMARY

OK现在让我们只是有一些在此表中的数据，以证明它像正常的MySQL运行。


mysql>use nosql_mysql_innodb_memcache;
mysql> insert into nosql_mysql VALUES ('key1','demo data','1',1,1);
Query OK, 1 row affected (0.04 sec)


select * from nosql_mysql \G
*************************** 1. row ***************************
demo_key: key1
demo_value: demo data
demo_flag: 1
demo_cas: 1
demo_expire: 1
1 row in set (0.00 sec)

因此，让我们看看我们能做些什么现在用PHP ...

PHP代码：

$memcache->connect('localhost', 11211) or die ("Could not connect");

$version = $memcache->getVersion();
echo "Server's version: ".$version."<br/>\n";

$memcache->set('key3', 'FROM PHP') or die ("Failed to save data at the server");
echo "Data from the cache:<br/>\n";
echo $memcache->get('key3');
?>

PHP的输出：
服务器版本：5.6.10
从高速缓存中的数据：
从PHP

我们所能做的只是笑着典型的例子，我们看到和使用telnet。


telnet 127.0.0.1 11211
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
set key2 1 0 11
Hello World
STORED
get key2
VALUE key2 1 11
Hello World
END
get key3
VALUE key3 0 8
FROM PHP
END

好吧，让我们看看我们在MySQL数据库中


set session TRANSACTION ISOLATION LEVEL read uncommitted;
SELECT @@GLOBAL.tx_isolation, @@tx_isolation \G
*************************** 1. row ***************************
@@GLOBAL.tx_isolation: REPEATABLE-READ
@@tx_isolation: READ-UNCOMMITTED


> select * from nosql_mysql\G
*************************** 1. row ***************************
demo_key: key1
demo_value: demo data
demo_flag: 1
demo_cas: 1
demo_expire: 1
*************************** 2. row ***************************
demo_key: key2
demo_value: Hello World
demo_flag: 1
demo_cas: 2
demo_expire: 0
*************************** 3. row ***************************
demo_key: key3
demo_value: FROM PHP
demo_flag: 0
demo_cas: 2
demo_expire: 0

因此，PHP和MySQL的InnoDB的memcache中，我们可以看到，我们能够直接地，以解决代码。

当然别人有自己的见解（ http://blog.couchbase.com/why-mysql-56-no-real-threat-nosql），但我认为这仅仅是一个开始，我们将如何能够使用NoSQL的MySQL的。
