LNMP environment construction (1) Building PHP environment
First download the PHP installation file. We use the source code to compile and install PHP5.4.36. Go to the PHP official website to download the PHP installation file.
Next, compile and install the PHP source code. After entering the source code directory, execute the following command to install:
Note: If you need mysql, it is best to do it during mutation Provide parameters and specify to use the mysqlnd library, otherwise the installation of separately compiled extensions can only use the MySQL Client Library.
The following error appears:
It prompts that libxml2 cannot be found, install it:
Continue to recompile, the following error appears:
Because we have enabled --with-openssl , therefore, we need to install openssl-devel:
Compile again, prompt:
GD library is not installed:
Continue compiling, prompt:
Not installed libmcrypt, this lib is not available in yum, so you need to download it and compile it manually:
Compile again:
Need Install libcurl:
Compile again, no errors:
configure is successful, start the installation:
If everything goes well, the beautiful artistic conception successfully compiles and installs PHP, installation directory In /usr/local/php.
Finally, we need to provide the PHP configuration file php.ini.
Note: The PHP installation directory is specified by the --prefix=directory parameter of configure . In addition, what we have built here is an environment for development. If it needs to be used as a production environment, you need to pay attention to some security issues. At the same time, it is recommended not to copy php.ini-development file, instead copy the php.ini-production file.
Check the PHP version:
For ease of operation, you can add the PHP directory to the environment variable. Edit ~/.bash_profile, in export PATH Add the following line above:
Then execute the following command:
In this way, we can use the command directly without adding a directory.
Tip: Check which configuration file PHP is using?
If the strace command is not installed, use yum install strace Just install it.
Install extension
Now that the basic PHP installation is complete, we need to install some extensions that meet business needs.
Install the yaf development framework extension
Execute the command to install using pecl:
If nothing else, the above command is enough to complete the installation of yaf:
Next, you need to install it in php. Enable yaf extension in ini file. Edit /usr/local/php/etc/php.ini
Install eAccelerator extension
in php Add eAccelerator configuration information in .ini:
Execute php -v You can see:
The above introduces the LNMP environment construction (1) Setting up the PHP environment, including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
