1、添加ubuntu nginx更新镜像源
sudo vi /etc/opt/source.list
添加:deb http://nginx.org/packages/ubuntu/ precise nginx
deb-src http://nginx.org/packages/ubuntu/ precise nginx
2、更新软件包源:
sudo apt-get update
出现如下错误:W: GPG 错误:http://nginx.org precise Release: 由于没有公钥,无法验证下列签名: NO_PUBKEY ABF5BD827BD9BF62
解决办法:sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys ABF5BD827BD9BF62
3、重新执行:sudo apt-get update
sudo apt-get install nginx
出现如下错误:etting up nginx (1.6.3-1~precise) ...
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()
invoke-rc.d: initscript nginx, action "start" failed.
原因:80端口被已经被其它进程使用。
解决办法:更改nginx服务绑定端口为88端口。sudo vi /etc/nginx/conf.d/default.conf
更改:server {
listen 88;
server_name localhost;
#charset koi8-r;
#access_log /var/log/nginx/log/host.access.log main;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
4、启动nginx
sudo /etc/init.d/nginx start
5、检查nginx版本
nginx -v
6、配置php+mysql
sudo apt-get install php5-cli php5-cgi mysql-server php5-mysql
7、安装FastCgi
sudo apt-get install spawn-fcgi
8、配置nginx
sudo vi /etc/nginx/conf.d/default.conf
location / {
root /usr/share/nginx/html;
index index.php index.html index.htm;#添加index.php
}
9、重启nginx
sudo /etc/init.d/nginx restart
10、启动fastcig php
spawn-fcgi -a 127.0.0.1 -p 9000 -C 10 -u nginx -f /usr/bin/php-cgi & #这里注意:我第一次加了&才行,还不知道为什么
参数含义如下
* -f 指定调用FastCGI的进程的执行程序位置,根据系统上所装的PHP的情况具体设置
* -a 绑定到地址addr
* -p 绑定到端口port
* -s 绑定到unix socket的路径path
* -C 指定产生的FastCGI的进程数,默认为5(仅用于PHP)
* -P指定产生的进程的PID文件路径
* -u和-g FastCGI使用什么身份(-u 用户 -g 用户组)运行,Ubuntu下可以使用www-data,其他的根据情况配置,如nobody、apache等现在可以在web根目录下放个探针或php文件测试一下了

11、加入开机启动:
sudo vi /etc/rc.local
把/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 10 -u nginx -f /usr/bin/php-cgi 加到exit 0前。
12、no input file specified错误
sudo vi /etc/nginx/conf.d/default.conf
其中这个字段
location ~ .php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;
include fastcgi_params;
}
注意
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;
/usr/share/nginx/html 改为你的网站根目录,一般就是改成这个。
server 字段下root 目录和网站根目录保持一致
13、使用雅黑探针来探测web服务器:下载雅黑探针php文件―tz.php到/usr/share/nginx/html
#sudo chown ngixn tz.php
#sudo chmod u+rwz tz.php
通过浏览器输入localhost:88/tz.php来查看web服务状态。
14、 安装discuz论坛
(1)在/usr/share/nginx/html下新建目录bbs:#mdir bbs ,下载discuz X3.1版本discuz.zip并上传到bbs中
(2)#sudo unzip discuz.zip
(3)#sudo chmod -R 777 discuz
(4)在浏览器中输入localhost:88/bbs/upload/install,开始安装论坛。

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
