#tar -zvxf mysql-5.5.27.tar.gz
4)、配置编译
#mkdir /usr/local/mysql
#mkdir /usr/local/mysql/data
#cd /usr/local/src/mysql-5.5.27
#cmake . \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DINSTALL_DATADIR=/usr/local/mysql/data \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DEXTRA_CHARSETS=all \
-DENABLED_LOCAL_INFILE=1
参数说明:
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql //安装目录
-DINSTALL_DATADIR=/usr/local/mysql/data //数据库存放目录
-DDEFAULT_CHARSET=utf8 //使用utf8字符
-DDEFAULT_COLLATION=utf8_general_ci //校验字符
-DEXTRA_CHARSETS=all //安装所有扩展字符集
-DENABLED_LOCAL_INFILE=1 //允许从本地导入数据
#make
#make install
注意事项:
重新编译时,需要清除旧的对象文件和缓存信息。
# make clean
# rm -f CMakeCache.txt
4)、设置目录权限
# cd /usr/local/mysql
# chown -R root:mysql . //把当前目录中所有文件的所有者所有者设为root,,所属组为mysql
# chown -R mysql:mysql data
5)、配置文件
# cp support-files/my-medium.cnf /etc/my.cnf //这个配置仅适合小内存系统(32M - 64M)
打开如下注释:
innodb_data_home_dir = /usr/local/mysql/data
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = /usr/local/mysql/data
innodb_buffer_pool_size = 16M
innodb_additional_mem_pool_size = 2M
innodb_log_file_size = 5M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50
添加默认字符集:
[client]
default-character-set = utf8 // 添加编码支持
[mysqld]
default-character-set = utf8 // 添加编码支持
max_connections = 10000 //根据服务器性能调节
basedir = /usr/local/mysql //设置安装目录,这样在系统启动时才能正确运行到/etc/rc.d/init.d/mysql start

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.
