1.1-php编译安装
1. MySQL安装(同LAMP里面的安装方法)
2. php安装
wget http://cn2.php.net/distributions/php-5.4.37.tar.bz2
tar jxf php-5.4.37.tar.bz2
useradd -s /sbin/nologin php-fpm
cd php-5.4.37
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --disable-ipv6 --with-curl
make && make install
3.增加php用户和用户组
useradd -s /sbin/nologing -M php-fpm
4.在源码目录下复制配置文件
cp php.ini-production /usr/local/php/etc/php.ini
5.php专属配置文件改名
mv /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
6.拷贝启动脚本:
cp /usr/local/src/php-5.4.37/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod 755 /etc/init.d/php-fpm
chkconfig --add php-fpm
chkconfig php-fpm on
service php-fpm start
测试php配置文件是否正常
/usr/local/php/sbin/php-fpm -t
注意:不能用启动脚本加-t 如:/etc/init.d/php-fpm -t
课后答疑
php.ini 是php的全局配置文件,比如我要配置时区,配置禁止函数。
php-fpm.conf 是php-fpm 专属的配置文件,比如配置运行服务的用户,配置启动参数等,咱们视频都有讲。
php-fpm 就是一个启动二进制文件。
学习lnmp 时 也是需要 先 安装mysql php nginx ? 那mysql 和php 的安装目录是不是不能和之前冲突?还有就是 之前不是已经编译安装过mysql 和php 了,难道不能共用么?
答:lnmp顺序,只要保证 php在mysql后面就行。 mysql可以共用,php不可以,因为编译参数都不一样。 你可以指定一个和apache的php不同的目录
lamp=linux+apache+mysql+php; lnmp=Linux+nginx+mysql+php 他们的区别在于apache和nginx和php结合的模式不同,我们讲的这两个架构中,php在编译的时候以一个模块的形式和apache成为了一个整体,这种情况下我们是可以把php的安装目录/usr/local/php删除的。而lnmp中的php启动了一个服务php-fpm,这种模式相当于nginx处理php脚本时,直接把请求转发给了php-fpm,说白了就是一个代理。这个php的安装目录是不可以删除的。 这两种模式其实是可以共存的,编译配置的时候,把prefix=后面的目录改一下即可,不让它覆盖。

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.
