在安装sqlserver2008、2012等时选择的是默认实例, 服务器 名称 也就是电脑的 名称 ,特别是 登录 本地 的数据库,需要输入电脑用户 名称 加上SQLEXPRESS 例如:zhangsan\SQLEXPRESS 而不是自己本机的ip 地址 :192.168.1.xx 内部网络别的电脑也无法访问。
在安装sqlserver2008、2012等时选择的是默认实例,服务器名称也就是电脑的名称,特别是登录本地的数据库,需要输入电脑用户名称加上SQLEXPRESS
例如:zhangsan\SQLEXPRESS 而不是自己本机的ip地址:192.168.1.xx 内部网络别的电脑也无法访问。
问题就来了,如何修改服务器名称呢,改成用本地IP或者用户名\SQLEXPRESS登录sqlserver?
解决办法:
1.开始程序=》Microsoft SQL Server 2012=》配置工具=》SQL Server 配置管理器=》SQLEXPRESS的协议=》TCP/IP 如下图:
2.点击TCP/IP 更改协议选项的为已启用为是,然后继续点击选项IP地址,把里边的所有的“TCP端口”都改成1433,IP2的地址改成你自己本地的IP,TCP动态端口改成空。
如果还是不知道怎么改,可以点击“MSSQLSERVER的协议”的“TCP/IP”,这里边的都已经改成1433端口,直接参考改成一样。
3.重启一下sqlserver服务即可,如下图:
4.再打开sqlserver直接用IP地址就能登录了。
注:sqlserver需要设置允许远程连接到此服务器。大部分都是允许,就怕万一有些设置不允许,为了安全着想。

Common security vulnerabilities in MySQL include SQL injection, weak passwords, improper permission configuration, and unupdated software. 1. SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.

Identifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.

To monitor the health and performance of MySQL servers, you should pay attention to system health, performance metrics and query execution. 1) Monitor system health: Use top, htop or SHOWGLOBALSTATUS commands to view CPU, memory, disk I/O and network activities. 2) Track performance indicators: monitor key indicators such as query number per second, average query time and cache hit rate. 3) Ensure query execution optimization: Enable slow query logs, record and optimize queries whose execution time exceeds the set threshold.

The main difference between MySQL and MariaDB is performance, functionality and license: 1. MySQL is developed by Oracle, and MariaDB is its fork. 2. MariaDB may perform better in high load environments. 3.MariaDB provides more storage engines and functions. 4.MySQL adopts a dual license, and MariaDB is completely open source. The existing infrastructure, performance requirements, functional requirements and license costs should be taken into account when choosing.

MySQL uses a GPL license. 1) The GPL license allows the free use, modification and distribution of MySQL, but the modified distribution must comply with GPL. 2) Commercial licenses can avoid public modifications and are suitable for commercial applications that require confidentiality.

The situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.
