Precise management, efficient obstacle avoidance: How AnQiCMS multi-site deployment cleverly avoids port conflicts
As an experienced website operation expert, I am well aware that in the current internet environment with multiple brands, businesses, and regions developing in parallel, efficiently and stably managing multiple websites is the key to the success of enterprise content operation.AnQiCMS, this powerful content management system developed based on the Go language, with its excellent multi-site management capabilities, has undoubtedly become a powerful assistant for many operation teams.However, when we deploy the AnQiCMS multi-site to the same server, a seemingly simple but often troublesome technical problem for beginners emerges: how to avoid potential port conflicts between different sites?
Today, let's delve deeply into this issue and provide a practical and easy-to-understand solution to ensure smooth and worry-free multi-site deployment of your AnQiCMS.
Understanding the multi-site philosophy of AnQiCMS
On the contrary, AnQiCMS provides a more elegant solution:An AnQiCMS application instance, which can support multiple independent front-end websites simultaneously through its powerful backend management features
Port conflict: why it occurs and how to avoid it?
AnQiCMS as an application developed in Go language, listens to a specific port during startup, for example the default one8001This is the "entry point" it provides for services. If only one AnQiCMS instance is running on your server, then it listens8001Port has no problem.However, when you want to deploy multiple AnQiCMS 'instances' (i.e., multiple completely independent copies of AnQiCMS applications, not the built-in multi-site feature of AnQiCMS) on the same server, or when you need to handle multiple domain names even though there is only one AnQiCMS instance, you may encounter port conflicts.
The core avoidance strategy, no matter which deployment scenario, cannot do without a key role of a 'scheduler'.Reverse proxy server.
1. The magic of reverse proxy: unified external and internal scheduling
Reverse proxy servers (such as Nginx or Apache) are the cornerstone for solving port conflicts.It plays the role of an intelligent traffic scheduler.When external users access your website through a domain name, the request first reaches the reverse proxy server.The reverse proxy will not directly return AnQiCMS content, but will forward the request to the actual port where AnQiCMS is running on the backend according to the rules you have set (usually the domain name).
- Unified externally:All websites can be accessed through standard:
HTTP(80)orHTTPS(443)Port access, users do not need to remember complex port numbers. - Internal isolation:The backend AnQiCMS application can run on any non-standard port (such as 8001, 8002, etc.), and they will not conflict with each other because external requests never directly reach these ports.
The flexibility of this mode lies in the fact that whether you are running an AnQiCMS instance to serve multiple logical sites or running multiple AnQiCMS instances, the reverse proxy can handle it perfectly.
2. Scene one: AnQiCMS instance manages multiple sites (recommended)
This is the most common and recommended usage of the multi-site feature in AnQiCMS. You only need to run one instance of AnQiCMS on the server, which may listen8001Port. Then, through the "Multi-site Management" feature of AnQiCMS backend, add your new site, and specify a unique domain name, root directory, and database for each new site.
In this mode, all requests (such as those accessed through a browser) to different domain names (e.g.,www.siteA.com/www.siteB.com）will first arrive at your reverse proxy server. The reverse proxy will forward all these requests to the unique AnQiCMS instance that is listening on the backend.8001Port. AnQiCMS applications automatically identify and render the corresponding site content based on the domain information in the request header after receiving a request.
Reverse proxy configuration example (taking Nginx as an example):
Assuming your AnQiCMS main instance is running inhttp://127.0.0.1:8001.
# 站点 A 的配置
server {
listen 80;
server_name www.siteA.com;
location @AnqiCMS {
proxy_pass http://127.0.0.1:8001;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
error_page 404 =200 @AnqiCMS; # 确保所有请求都经过AnQiCMS处理，包括伪静态
location / {
try_files $uri $uri/index.html @AnqiCMS;
}
}
# 站点 B 的配置
server {
listen 80;
server_name www.siteB.com;
location @AnqiCMS {
proxy_pass http://127.0.0.1:8001; # 注意，这里仍然指向同一个AnQiCMS实例的8001端口
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
error_page 404 =200 @AnqiCMS;
location / {
try_files $uri $uri/index.html @AnqiCMS;
}
}
In AnQiCMS background, you also need to add in the "Multi-site Management"www.siteA.comandwww.siteB.comThese two logical sites.The panel, 1Panel, or aaPanel and other integrated management tools usually provide a simplified interface to complete the creation of these reverse proxy and AnQiCMS backend sites.
3. Scenario two: multiple AnQiCMS instances, each instance with a port (highly isolated)
In certain specific scenarios, you may want to run multiple instances on the same server for reasons such as version isolation, performance independence, and testing environment requirements.Fully independentThe AnQiCMS application instance. The key to avoiding port conflicts is to assign a unique internal listening port for each AnQiCMS instance.An unparalleled internal listening port.
For example, the first AnQiCMS instance listens8001, the second instance listens8002, the third instance listens8003. This applies to each AnQiCMS application itself.config.jsonFile needs to make corresponding port modifications (for example, changingport: 8001toport: 8002).
Reverse proxy configuration example (taking Nginx as an example):
AssumesiteC.comlistened8002The AnQiCMS instance on the port provides services,siteD.comlistened8003The AnQiCMS instance on the port provides services.
"nginx"
Configuration of Site C
server {
listen 80;
server_name www.siteC.com;
location @AnqiCMS_C {
