Installation and basic configuration of nginx, and multiple domain name services
centos6.x yum does not have nginx software package by default
Installation method:
Go to the nginx download page http://nginx.org/en/linux_packages.html#stable and copy the nginx software source installation package of CENTOS 6
Run the command: wget http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
Install the rpm package yum install nginx-release-centos-6-0.el6.ngx.noarch.rpm -y , this step actually just adds the nginx package source
Execute yum install nginx -y to install nginx
nginx is installed as a Linux service by default
Use service nginx start, stop, restart, try-restart, reload, force-reload, status to operate nginx
nginx’s configuration file reads the /etc/nginx/nginx.conf file by default
The configuration of nginx is composed of directives, which are composed of simple instructions or block instructions
Simple command: listen 80;
Block instructions are included by {}, and block instructions can include multiple simple instructions and block instructions:
<code>http <span>{ server { }</span> }</code>
http can have multiple servers, and multiple servers can listen to multiple ports and provide services for multiple applications on the same server. .
But if you have multiple domain names www.you.com, news.you.com, mail.you.com serving on the same server at the same time, then www.you.com, mail.you.com:8080, news.you The access method like .com:81 is obviously inappropriate. Fortunately, nginx has provided rules for filtering by domain name
<code><span>server</span> { listen <span>80</span>; server_name www.you.com; location / { <span>#....</span> proxy_pass http:<span>//localhost:8880;</span> } <span>##### other directive</span> } <span>server</span> { listen <span>80</span>; server_name news.you.com; location / { <span>#....</span> proxy_pass http:<span>//localhost:8881;</span> } <span>##### other directive</span> } <span>server</span> { listen <span>80</span>; server_name mail.you.com; location / { <span>#....</span> proxy_pass http:<span>//localhost:8882;</span> } <span>##### other directive</span> }</code>
In the end, just run each application and listen to the corresponding port.
').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });The above has introduced the installation and basic configuration of nginx, as well as multiple domain name services, including related content. I hope it will be helpful to friends who are interested in PHP tutorials.

Effective methods to prevent session fixed attacks include: 1. Regenerate the session ID after the user logs in; 2. Use a secure session ID generation algorithm; 3. Implement the session timeout mechanism; 4. Encrypt session data using HTTPS. These measures can ensure that the application is indestructible when facing session fixed attacks.

Implementing session-free authentication can be achieved by using JSONWebTokens (JWT), a token-based authentication system where all necessary information is stored in the token without server-side session storage. 1) Use JWT to generate and verify tokens, 2) Ensure that HTTPS is used to prevent tokens from being intercepted, 3) Securely store tokens on the client side, 4) Verify tokens on the server side to prevent tampering, 5) Implement token revocation mechanisms, such as using short-term access tokens and long-term refresh tokens.

The security risks of PHP sessions mainly include session hijacking, session fixation, session prediction and session poisoning. 1. Session hijacking can be prevented by using HTTPS and protecting cookies. 2. Session fixation can be avoided by regenerating the session ID before the user logs in. 3. Session prediction needs to ensure the randomness and unpredictability of session IDs. 4. Session poisoning can be prevented by verifying and filtering session data.

To destroy a PHP session, you need to start the session first, then clear the data and destroy the session file. 1. Use session_start() to start the session. 2. Use session_unset() to clear the session data. 3. Finally, use session_destroy() to destroy the session file to ensure data security and resource release.

How to change the default session saving path of PHP? It can be achieved through the following steps: use session_save_path('/var/www/sessions');session_start(); in PHP scripts to set the session saving path. Set session.save_path="/var/www/sessions" in the php.ini file to change the session saving path globally. Use Memcached or Redis to store session data, such as ini_set('session.save_handler','memcached'); ini_set(

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.
