以下的文章主要介绍的是MySQL手动安装的实际操作方法和中文的具体解决方案,我们所演示的环境是在Debian Etch Linux上对MySQL(和PHP搭配之最佳组合) 5.0.27 icc版本进行安装,并使用JDBC测试中文成功!
中文问题的关键是全部使用UTF-8编码,MySQL(和PHP搭配之最佳组合) 5发布版支持UTF-8,但默认为latin1,Java在内部使用的全部是Unicode,因此要保证jsp(SUN企业级应用的首选)页面以UTF-8编码,JDBC驱动采用官方Connector4J 5.0.4,在resin(一个免费的JSP运行平台) 3.1/Spring 2.0/Hibernate 3.2环境下测试中文正常。
1. MySQL手动安装方法与中文解决方案之一。下载"MySQL(和PHP搭配之最佳组合)-standard-5.0.27-linux-i686-icc-glibc23.tar.gz",推荐ICC版本,据称比GCC性能提高10-20%
2. 复制到/usr/local/,解压:tar zxvf MySQL(和PHP搭配之最佳组合)-standard-5.x....tar.gz
3. 添加用户和组MySQL(和PHP搭配之最佳组合):
groupadd MySQL(和PHP搭配之最佳组合)
useradd -g MySQL(和PHP搭配之最佳组合) MySQL(和PHP搭配之最佳组合)
4. 创建符号连接:/usr/local ln -s MySQL(和PHP搭配之最佳组合)-standard-5.x... MySQL(和PHP搭配之最佳组合)
5. cd MySQL(和PHP搭配之最佳组合),当前目录改为/usr/local/MySQL(和PHP搭配之最佳组合)/
6. 运行脚步初始化数据库:./scripts/MySQL(和PHP搭配之最佳组合)_install_db --user=MySQL(和PHP搭配之最佳组合)
7. 设置权限:
/usr/local/MySQL(和PHP搭配之最佳组合) chown -R root .
/usr/local/MySQL(和PHP搭配之最佳组合) chown -R MySQL(和PHP搭配之最佳组合) data
/usr/local/MySQL(和PHP搭配之最佳组合) chgrp -R MySQL(和PHP搭配之最佳组合)
8.MySQL手动安装方法与中文解决方案: 根据需要创建并修改/etc/my.cnf,参考配置:
[MySQL(和PHP搭配之最佳组合)d]
设置默认为INNODB表,支持事务:
<ol class="dp-xml"><li class="alt"><span><span class="attribute">default-storage-engine</span><span>=</span><span class="attribute-value">INNODB</span><span> </span></span></li></ol>
设置默认的字符集UTF-8:
<ol class="dp-xml"> <li class="alt"><span><span class="attribute">character-set-server</span><span>=</span><span class="attribute-value">utf8</span><span> </span></span></li> <li> <span class="attribute">collation-server</span><span>=</span><span class="attribute-value">utf8_general_ci</span><span> </span> </li> <li class="alt"> <span class="attribute">default-character-set</span><span>=</span><span class="attribute-value">utf8</span><span> </span> </li> </ol>
禁用bdb:
skip-bdb
9. 启动MySQL(和PHP搭配之最佳组合):
/usr/local/MySQL(和PHP搭配之最佳组合)/bin ./MySQL(和PHP搭配之最佳组合)d_safe --user=MySQL(和PHP搭配之最佳组合) &
10. 初始化root口令:
/usr/local/MySQL(和PHP搭配之最佳组合)/bin ./MySQL(和PHP搭配之最佳组合)admin -u root -p password "password-of-root"
Enter password:
11. 以root登录创建数据库:
/usr/local/MySQL(和PHP搭配之最佳组合) ./MySQL(和PHP搭配之最佳组合) -u root -p
Enter password: password-of-root
12. 创建一个新用户:
<ol class="dp-xml"><li class="alt"><span><span>MySQL(和PHP搭配之最佳组合)</span><span class="tag">></span><span> create user test identified by 'test-password'; </span></span></li></ol>
13. 创建一个新数据库:
<ol class="dp-xml"><li class="alt"><span><span>MySQL(和PHP搭配之最佳组合)</span><span class="tag">></span><span> create database testdb default character set utf8 default collate utf8_general_ci; </span></span></li></ol>
百度i贴吧 新浪微博 务必指定字符集和排序方式,均为UTF-8,这样才能保证创建的表也使用UTF-8。
14. 赋予test用户从localhost访问testdb的权限,并使用口令:
<ol class="dp-xml"><li class="alt"><span><span>MySQL(和PHP搭配之最佳组合)</span><span class="tag">></span><span> grant all on testdb.* to test@localhost identified by 'test-password'; </span></span></li></ol>
注意:要使用JDBC从远程连接MySQL(和PHP搭配之最佳组合),就必须正确设置test用户权限,MySQL(和PHP搭配之最佳组合)的访问权限由用户名,客户端机器名和口令共同组成,上例表示仅允许test用户在本机(localhost)通过口令连接MySQL(和PHP搭配之最佳组合)。
15. MySQL手动安装方法与中文解决方案:停止MySQL(和PHP搭配之最佳组合)服务器:
<ol class="dp-xml"> <li class="alt"><span><span>/usr/local/MySQL(和PHP搭配之最佳组合)/bin # ./MySQL(和PHP搭配之最佳组合)admin -u root -p shutdown </span></span></li> <li><span>Enter password: password-of-root </span></li> <li class="alt"><span>STOPPING server from pid file /usr/local/MySQL(和PHP搭配之最佳组合)/data/debian.pid </span></li> <li><span>xxx MySQL(和PHP搭配之最佳组合)d ended </span></li> </ol>
中文秘籍:
/etc/my.cnf中所有与编码相关的设置均要设定为UTF-8,参考步骤8。
按以下步骤调试:
<ol class="dp-xml"><li class="alt"><span><span>MySQL(和PHP搭配之最佳组合)</span><span class="tag">></span><span> status; </span></span></li></ol>
注意characterset相关值,必须保证全部为utf8,否则,修改/etc/my.cnf,参考步骤8。
<ol class="dp-xml"><li class="alt"><span><span>MySQL(和PHP搭配之最佳组合)</span><span class="tag">></span><span> show variables like '%char%'; </span></span></li></ol>
除了character_set_filesystem显示为binary外,其余应该全部显示为utf8,若非utf8,修改/etc/my.cnf,参考步骤8。
<ol class="dp-xml"><li class="alt"><span><span>MySQL(和PHP搭配之最佳组合)</span><span class="tag">></span><span> show variables like '%collation%'; </span></span></li></ol>
显示应该全部为utf8_general_ci,否则,修改/etc/my.cnf,参考步骤8。
<ol class="dp-xml"><li class="alt"><span><span>MySQL(和PHP搭配之最佳组合)show -u root -p -i database-name </span></span></li></ol>
作用:显示数据库详细信息,如果你没有看到utf8_general_ci,而是latin_swedish_ci,说明数据库编码非UTF-8,中文肯定不正常,删之,然后参考步骤13以UTF-8重新创建数据库。
以上的相关内容就是对MySQL手动安装方法与中文解决方案的介绍,望你能有所收获。

Stored procedures are precompiled SQL statements in MySQL for improving performance and simplifying complex operations. 1. Improve performance: After the first compilation, subsequent calls do not need to be recompiled. 2. Improve security: Restrict data table access through permission control. 3. Simplify complex operations: combine multiple SQL statements to simplify application layer logic.

The working principle of MySQL query cache is to store the results of SELECT query, and when the same query is executed again, the cached results are directly returned. 1) Query cache improves database reading performance and finds cached results through hash values. 2) Simple configuration, set query_cache_type and query_cache_size in MySQL configuration file. 3) Use the SQL_NO_CACHE keyword to disable the cache of specific queries. 4) In high-frequency update environments, query cache may cause performance bottlenecks and needs to be optimized for use through monitoring and adjustment of parameters.

The reasons why MySQL is widely used in various projects include: 1. High performance and scalability, supporting multiple storage engines; 2. Easy to use and maintain, simple configuration and rich tools; 3. Rich ecosystem, attracting a large number of community and third-party tool support; 4. Cross-platform support, suitable for multiple operating systems.

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.
