nginx location matching rules
location matching command
~ #The wavy line means performing a regular match, case-sensitive
~* #Indicates performing a regular match, case-insensitive
^~ #^~ means normal character matching, if the option matches , only matches this option and does not match other options. It is generally used to match directories
= #Exact matching of ordinary characters
@ #"@" Defines a named location, used for internal orientation, such as error_page, try_files
The priority of location matching (regardless of the order of locations in the configuration file)
= Exact matches will be processed first. If an exact match is found, nginx stops searching for other matches.
Ordinary character matching, regular expression rules and long block rules will be prioritized for query matching, which means that if the item matches, you need to check whether there are regular expression matches and longer matches.
^~ will only match this rule, and nginx will stop searching for other matches, otherwise nginx will continue to process other location instructions.
Finally match the instructions with "~" and "~*". If a corresponding match is found, nginx stops searching for other matches; when there is no regular expression or no regular expression is matched, then the matching degree is the highest The verbatim matching directive will be used.
location priority official document
- Directives with the = prefix that match the query exactly. If found, searching stops.
- All remaining directives with conventional strings, longest match first. If this match used the ^~ prefix , searching stops.
- Regular expressions, in order of definition in the configuration file.
- If #3 yielded a match, that result is used. Else the match from #2 is used.
- =prefixed directive strict match this query. If found, stop searching.
- All remaining regular strings, longest match. If the match uses the ^? prefix, the search stops.
- Regular expression, in the order defined in the configuration file.
- If rule 3 produces a match, the result is used. Otherwise, the same as from rule 2 is used.
For example
location = / { # 只匹配"/". [ configuration A ] } location / { # 匹配任何请求,因为所有请求都是以"/"开始 # 但是更长字符匹配或者正则表达式匹配会优先匹配 [ configuration B ] } location ^~ /images/ { # 匹配任何以 /images/ 开始的请求,并停止匹配 其它location [ configuration C ] } location ~* \.(gif|jpg|jpeg)$ { # 匹配以 gif, jpg, or jpeg结尾的请求. # 但是所有 /images/ 目录的请求将由 [Configuration C]处理. [ configuration D ] }
The above introduces the nginx location matching rules, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.

To allow the Tomcat server to access the external network, you need to: modify the Tomcat configuration file to allow external connections. Add a firewall rule to allow access to the Tomcat server port. Create a DNS record pointing the domain name to the Tomcat server public IP. Optional: Use a reverse proxy to improve security and performance. Optional: Set up HTTPS for increased security.

The start and stop commands of Nginx are nginx and nginx -s quit respectively. The start command starts the server directly, while the stop command gracefully shuts down the server, allowing all current requests to be processed. Other available stop signals include stop and reload.

Steps to run ThinkPHP Framework locally: Download and unzip ThinkPHP Framework to a local directory. Create a virtual host (optional) pointing to the ThinkPHP root directory. Configure database connection parameters. Start the web server. Initialize the ThinkPHP application. Access the ThinkPHP application URL and run it.

To register for phpMyAdmin, you need to first create a MySQL user and grant permissions to it, then download, install and configure phpMyAdmin, and finally log in to phpMyAdmin to manage the database.

Server deployment steps for a Node.js project: Prepare the deployment environment: obtain server access, install Node.js, set up a Git repository. Build the application: Use npm run build to generate deployable code and dependencies. Upload code to the server: via Git or File Transfer Protocol. Install dependencies: SSH into the server and use npm install to install application dependencies. Start the application: Use a command such as node index.js to start the application, or use a process manager such as pm2. Configure a reverse proxy (optional): Use a reverse proxy such as Nginx or Apache to route traffic to your application

To solve the "Welcome to nginx!" error, you need to check the virtual host configuration, enable the virtual host, reload Nginx, if the virtual host configuration file cannot be found, create a default page and reload Nginx, then the error message will disappear and the website will be normal show.

nginx appears when accessing a website. The reasons may be: server maintenance, busy server, browser cache, DNS issues, firewall blocking, website misconfiguration, network connection issues, or the website is down. Try the following solutions: wait for maintenance to end, visit during off-peak hours, clear your browser cache, flush your DNS cache, disable firewall or antivirus software, contact the site administrator, check your network connection, or use a search engine or web archive to find another copy of the site. If the problem persists, please contact the site administrator.

There are five methods for container communication in the Docker environment: shared network, Docker Compose, network proxy, shared volume, and message queue. Depending on your isolation and security needs, choose the most appropriate communication method, such as leveraging Docker Compose to simplify connections or using a network proxy to increase isolation.
