mysql - 编译PHP时的扩展库配置问题
在编译PHP时,有很多的配置选项,如下:
--with-curl=DIR
--with-mysql=DIR
--with-gd=DIR
--enable-fpm
问题1:上面不都是php的扩展库吗,在编译php时一起进行编译,为什么有的用--with,而有的用--enable?
问题2:上面的扩展库在php源文件的ext目录下都有,那个DIR代表什么意思,官方的解释很是看不懂。

1. --with是把它直接编译到php可执行文件中,--enable是编译成 .so 或者 .dll 然后在 php.ini 中load进去。
- --with的都是需要依赖第三方库的,但是如果第三方库在默认位置上,就可以忽略[=DIR];--enable的是不需要依赖第三方库的。
- 这些扩展库很多都只是对第三方库的封装(提供binding),这个dir就是需要指定这些第三方库文件所在的位置。

MySQL and phpMyAdmin are powerful database management tools. 1) MySQL is used to create databases and tables, and to execute DML and SQL queries. 2) phpMyAdmin provides an intuitive interface for database management, table structure management, data operations and user permission management.

Docker is important on Linux because Linux is its native platform that provides rich tools and community support. 1. Install Docker: Use sudoapt-getupdate and sudoapt-getinstalldocker-cedocker-ce-clicotainerd.io. 2. Create and manage containers: Use dockerrun commands, such as dockerrun-d--namemynginx-p80:80nginx. 3. Write Dockerfile: Optimize the image size and use multi-stage construction. 4. Optimization and debugging: Use dockerlogs and dockerex

IIS and PHP are compatible and are implemented through FastCGI. 1.IIS forwards the .php file request to the FastCGI module through the configuration file. 2. The FastCGI module starts the PHP process to process requests to improve performance and stability. 3. In actual applications, you need to pay attention to configuration details, error debugging and performance optimization.

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.

CentOS is the first choice for server and enterprise environments for its superior security, stability and performance. 1) Security provides forced access control through SELinux to improve system security. 2) Stability is supported by the LTS version for up to 10 years to ensure the stability of the system. 3) Performance significantly improves system response speed and resource utilization by optimizing kernel and system configuration.

MySQL is suitable for rapid development and small and medium-sized applications, while Oracle is suitable for large enterprises and high availability needs. 1) MySQL is open source and easy to use, suitable for web applications and small and medium-sized enterprises. 2) Oracle is powerful and suitable for large enterprises and government agencies. 3) MySQL supports a variety of storage engines, and Oracle provides rich enterprise-level functions.

In Linux, file and directory management uses ls, cd, mkdir, rm, cp, mv commands, and permission management uses chmod, chown, and chgrp commands. 1. File and directory management commands such as ls-l list detailed information, mkdir-p recursively create directories. 2. Permission management commands such as chmod755file set file permissions, chownuserfile changes file owner, and chgrpgroupfile changes file group. These commands are based on file system structure and user and group systems, and operate and control through system calls and metadata.

The core components of Linux include kernel, file system, shell, user and kernel space, device drivers, and performance optimization and best practices. 1) The kernel is the core of the system, managing hardware, memory and processes. 2) The file system organizes data and supports multiple types such as ext4, Btrfs and XFS. 3) Shell is the command center for users to interact with the system and supports scripting. 4) Separate user space from kernel space to ensure system stability. 5) The device driver connects the hardware to the operating system. 6) Performance optimization includes tuning system configuration and following best practices.
