mysql yum安装_MySQL
一、安装问题:
首先进入 :http://dev.mysql.com/downloads/repo/yum/ 下载界面,拿到rpm的地址
选择yum下载:
2、下载redhat 6 对应的rpm
右键另存为 连接地址:
在linux 服务器上下载这个rpm服务器:
wget http://dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm
本地安装 repository
<code lang="">sudo yum localinstall mysql-community-release-el6-5.noarch.rpm</code>
操作完成后,当前server还没有安装任何的软件。所以我我们还得安装 MySQL Server:
<code lang=""><code lang="">sudo yum install mysql-community-server</code></code>
<code lang="">mysql 的安装路径为: /var/lib/mysql
<code lang="">理论上,这步完成后,就可以启动mysql了。
<code lang=""><code lang=""><code lang="">sudo service mysqld start</code></code></code>
<code lang=""><code lang="">但是,当我启动的时候,我报错了
<code lang=""><code lang=""><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c150410/142V3I0351560-435F.jpg" class="lazy" alt="\" />
<code lang=""><code lang="">查看错误日志:
<code lang=""><code lang=""><code lang=""><code lang="">cat /var/log/mysqld.log</code></code></code></code>
<code lang=""><code lang=""><code lang=""><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c150410/142V3I03A620-51A5.jpg" class="lazy" alt="\" />
<code lang=""><code lang=""><code lang="">发现者三个文件是多余的,直接把这些文件删了。重启下就好了,删除路径如下所示:
<code lang=""><code lang=""><code lang=""><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c150410/142V3I03RQ0-62U3.jpg" class="lazy" alt="\" />
<code lang=""><code lang=""><code lang="">然后直接登录。(默认的账号和密码都是 root /root)
<code lang=""><code lang=""><code lang=""><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c150410/142V3I0401560-M530.jpg" class="lazy" alt="\" />
<code lang=""><code lang=""><code lang="">这就算装好了。
<code lang=""><code lang=""><code lang="">二、远程登录问题
<code lang=""><code lang=""><code lang="">我用第三方远程连接的时候,报错。查了下,发现有两个root用户,其中有一个是绑定本机(127.0.0.1)登录的。
<code lang=""><code lang=""><code lang=""><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c150410/142V3I041GZ-U515.jpg" class="lazy" alt="\" />
<code lang=""><code lang=""><code lang="">所以想办法改变所有root的密码:
<code lang=""><code lang=""><code lang=""><code lang="">mysql> use mysql;<br>
mysql> UPDATE user SET password=password("root") WHERE user='root';<br>
mysql> flush privileges;<br>
mysql> exit;
然后再登录,就ok了。

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.
