问题:在一个某处运行的MySQL服务器上,我该怎样通过命令行创建和安装一个MySQL数据库呢?
为了能通过命令行创建一个MySQL数据库,你可以使用mysql命令行客户端。下面是通过mysql命令行客户端创建和安装MySQL的步骤。
--------------------------------------分割线 --------------------------------------
Ubuntu 14.04下安装MySQL
《MySQL权威指南(原书第2版)》清晰中文扫描版 PDF
Ubuntu 14.04 LTS 安装 LNMP Nginx\PHP5 (PHP-FPM)\MySQL
Ubuntu 14.04下搭建MySQL主从服务器
Ubuntu 12.04 LTS 构建高可用分布式 MySQL 集群
Ubuntu 12.04下源代码安装MySQL5.6以及Python-MySQLdb
MySQL-5.5.38通用二进制安装

第一步:安装MySQL客户端当然你得确保MySQL客户端已经安装完毕。如果没有的话,可以按照下面的方法。
在Debian,Ubuntu 或者 Linux Mint上:
在Fedora,CentOS 或者 RHEL上:
第二步:登陆到MySQL服务器首先,你需要使用root用户登陆进你的MySQL数据库,如下:
请注意:为了能登进远程的MySQL服务器,你需要开启服务器上的远程访问(),如果你想调用同一主机上的MySQL服务器,你可以省略 "-h " 参数
你将需要输入MySQL服务器的密码,如果认证成功,MySQL提示将会出现。
在MySQL提示中输入命令之前,请记住所有的命令都是以分号结束的(否则将不会执行)。另外,考虑输入命令的时候使用大些字母,输入数据库对象使用小写字母。但那不是必须的,,只是方便你的阅读。
现在,让我们创建一个叫做xmodulo_DB的数据库:
第四步:创建一个数据库表为了达到演示的目的,我们将会创建一个叫做posts_tbl的表,表里会存储关于文章的如下信息:
这个过程分两步执行:
首先,选择我们需要使用的数据库:
然后,在数据库中创建新表:

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.
