After Mysql compiles the Mysql development library, you don’t need to specify the path to mysql.

PHP compilation has basic dependencies. To compile PHP, you first need to install the XML extension, because the php5 core has XML support turned on by default. Other basic libraries require the following:

GD -> zlib, Png, Jpg, if you need to support others, you still need to compile the extension library according to the actual situation. The ttf library needs the support of the freetype library.

--enable-magic-quotes is an extremely not recommended parameter. Of course, if you need PHP to do the underlying work for you, it actually does not solve the problem very thoroughly.

--with-openssl, requires openssl library.

mysqli is a MySQL driver provided by the MySQL team and has many practical functions and typical features. However, it is not the best choice for MySQL on the PHP platform. PDO has been proven to be a simple, high-concurrency, and easy-to-create and recycle standard interface. However, PDO also experienced memory overflow problems before 5.3. After 5.3, when reading Oracle's LOB resources, if the memory is not restricted, memory overflow will still occur.

If it is product mode, it is not recommended to use pear, shmop, ftp, etc. What they want to do is using C/C++, Java, or even other scripting languages. There are good and fast options, no need to be limited to Use PHP to implement it. Unfamiliar class libraries and libraries that are not commonly used are not recommended. Magic-quote, session.auto_start, PHP server information, PHP error information, etc. should be closed as soon as possible after compilation is completed to avoid exposing server information.

The Web Server mode corresponding to PHP only requires one of Module, fastcgi, and fpm. The server is not your experimental field. Fastcgi can choose Nginx and lighttpd. In fact, Nginx also uses lighttpd's spwan-fcgi for fcgi process management. fpm uses PHP itself to manage multiple processes, somewhat similar to a back-end proxy. Regardless of the mode, when releasing a product server, process and thread tuning should be done, and enough stress testing should be done to find the best combination of process numbers.

Choose a PHP OPCode cache extension. This is also very important. Under Linux 2.6 core and fcgi, xcache has good practical experience. Others will have serious performance degradation after the number of concurrency increases.

If you really want to experience it, you would rather compile several PHP versions than collect various extensions for one version of PHP to adapt to various environments. This will put yourself in a dilemma
