FreeBSD 下Web环境的构建.
1 安装MySQL
这里是自己使用源码编译安装。
需要下载MySQL-4.0.25源码包。
cd /opt/distfiles
wget xxx
tar -zxvf mysql-4.0.25.tar.gz -C src
cd src/mysql-4.0.25/
./configure ?prefix=/opt/modules/mysql
?enable-assembler
?with-mysqld-ldflags=-all-static
?with-charset=gb2312
?without-debug
make
make install
/opt/modules/mysql/bin/mysql_install_db
chown -R mysql.mysql /opt/modules/mysql/var
chgrp mysql /opt/modules/mysql
2 安装PHP
./configure
?prefix=/opt/modules/phpcgi
?enable-fastcgi
?enable-force-cgi-redirect
?enable-bcmath
?enable-inline-optimization
?enable-magic-quotes
?enable-wddx?disable-debug
?enable-sysvmsg
?enable-sockets
?enable-mbstring
?enable-calendar
?with-trans-sid
?with-ldap
?with-ldap-sasl
?with-mysql=/opt/modulels/mysql
3 安装lighttpd
cd /usr/ports/www/lighttpd/
make install clean
执行后,将会提示一些选项只要选中OPENSSL 就可以了,其他的不用选。
4 整合配置
4.1 修改默认网站文件路径
server.document-root = “/opt/data/www/”
4.2 打开fastcgi模块支持
将 #”mod_fastcgi”, 的#去掉
4.3 设定PHP支持
#### fastcgi module
## read fastcgi.txt for more info
fastcgi.server = ( “.php” =>
( “localhost” =>
(
“socket” => “/tmp/php-fastcgi.socket”,
“bin-path” => “/opt/modules/phpcgi/bin/php”,
# 如果你的网站很繁忙,可以加入如下设置
#”bin-environment” => (
# “PHP_FCGI_CHILDREN” => “16″,
# “PHP_FCGI_MAX_REQUESTS” => “10000″
#)
#”bin-path” => “/usr/local/bin/php”
)))
4.4 创建日志文件及设置权限
touch /var/log/lighttpd.error.log
touch /var/log/lighttpd.access.log
chown www:www /var/log/lighttpd.*
4.5 设置SSL支持
4.5.1 创建证书
cd /opt/etc/
openssl req -new -x509 -keyout server.pem -out server.pem -days 365 -nodes
4.5.2 打开SSL支持
#### SSL engine
ssl.engine = “enable”
ssl.pemfile = “/opt/etc/server.pem”
4.6 设置监听端口
默认的监听端口是 80,如果需要更改端口,可以修改配置设定。
## bind to port (default: 80)
#server.port = 81
5 启动
5.1 设置自动启动
vi /etc/rc.conf
lighttpd_enable=”YES”
5.2 手工启动
/usr/local/etc/rc.d/lighttpd.sh start
注意,如果没有在/etc/rc.conf添加 /etc/rc.conf ,是不能启动的。所以需要先添加。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

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.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

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.
