Ubuntu 8.04里面的MySQL版本是5.0.51a。在软件包mysql-server-5.0中,,不仅携带了集群服务器管理程序(ndb_mgmd),还携带了集群管理客户端(ndb_mgm)。客户端ndb_mgm可以用来显示集群的状态,让你了解集群的工作情况。
本节我们来安装、配置mysql-mgm.mytest.com(192.168.1.10)。
安装MySQL
在mysql-mgm.mytest.com服务器上,安装MySQL服务器:
$ sudo apt-get update install mysql-server
安装时,安装程序会要求你设置MySQL的root口令。请设置好,并记住该口令。
配置ndb_mgmd.cnf
现在我们来创建MySQL的集群配置文件,该文件路径为/etc/mysql/ndb_mgmd.cnf:
$ sudo nano /etc/mysql/ndb_mgmd.cnf
警告 文件名必须是ndb_mgmd.cnf,否则服务无法启动。
输入如下内容:
[NDBD DEFAULT]
NoOfReplicas=2
[MYSQLD DEFAULT]
[NDB_MGMD DEFAULT]
[TCP DEFAULT]
[NDB_MGMD] # 管理节点
HostName=192.168.1.10 # 本机(管理节点)的IP地址
[NDBD] # 存储节点1
HostName=192.168.1.13
DataDir=/var/lib/mysql-cluster
BackupDataDir=/var/lib/mysql-cluster/backup
[NDBD] # 存储节点2
HostName=192.168.1.14
DataDir=/var/lib/mysql-cluster
BackupDataDir=/var/lib/mysql-cluster/backup
# 有几个存储节点,就写几行[MYSQLD]
[MYSQLD]
[MYSQLD]
文件保存后,即可启动MySQL的mgm服务了:
$ sudo /etc/init.d/mysql-ndb-mgm start
以后,如果要停止MySQL集群,只需要停止该mgm服务即可。

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.
