As an experienced website operation expert, I fully understand the importance of every link in the process of building and maintaining a website, especially for a system like AnQiCMS (AnQiCMS) that pursues efficiency and stability. The configuration after deployment needs to be finely crafted. Today, let's delve into the manual deployment of AnQiCMS, and the Nginx reverse proxy andcrontabWhat is the relationship between scheduled tasks and how do they collectively ensure the stable operation of your website.
After manually deploying the AnQi CMS, configure Nginx reverse proxy andcrontabWhat is the relation?
When discussing the manual deployment of AnQiCMS, it often means that we need to personally configure the necessary infrastructure in the server environment. This includes Nginx reverse proxy andcrontabScheduling tasks play a crucial role, although they perform their respective duties, they also collaborate closely to build the foundation of stable and efficient website operation.
Nginx Reverse Proxy: The Facade and Traffic Hub of the Website
Let's talk about Nginx reverse proxy.Imagine that your AnQiCMS application is like a meticulously constructed office building, it may be running in some specific 'room' (such as the default port 8001) inside the server, rather than directly facing the 'main street' (standard ports 80 or 443).This is where Nginx acts as the 'front desk receptionist' and 'traffic hub' of this building.
The core function of Nginx lies in:
- Unified Entry and Port Conversion:The browser used by the user to visit your website defaults to HTTP port 80 or HTTPS port 443.However, AnQiCMS itself is an application written in Go language and usually binds to a non-standard port (such as 8001 mentioned in the document).The function of Nginx is to listen to these standard ports and forward (proxy) external requests to the internal ports where AnQiCMS application is actually running.Thus, users do not need to know the internal port of AnQiCMS and can access the website through a familiar domain.
- Domain and SSL Management:Through Nginx, you can easily direct multiple domain names to the same AnQiCMS instance (although AnQiCMS itself supports multi-site management, Nginx is still necessary for external traffic distribution), and configure SSL certificates to achieve HTTPS encrypted access, ensuring data transmission security.
- Static resource processing and performance optimization:The website usually contains a large number of images, CSS, JavaScript, and other static files.Nginx can efficiently handle these static file requests directly without needing to forward them to the AnQiCMS application for processing.This not only reduces the load of AnQiCMS, but also greatly improves the website's access speed and user experience through Nginx's powerful static file service capabilities (such as caching, compression).
- Pseudo-static rules and SEO:AnQiCMS has built-in powerful pseudo-static and 301 redirect management functions to optimize URL structure and enhance SEO effects.While Nginx is the executor that makes these pseudo-static rules effective at the server level.
try_filesandproxy_passRules, Nginx can correctly route URL requests that match the pseudo-static pattern to AnQiCMS for processing, ensuring SEO-friendliness.
In AnQiCMS manual deployment, the key to Nginx configuration lies in that classic proxy code: it tells Nginx to forward all requests (or requests that match specific rules) to the internal address and port of AnQiCMS, for exampleproxy_pass http://127.0.0.1:8001;. It can be said that without Nginx, even if AnQiCMS runs well on the server, it cannot be accessed by the public, and the website loses its significance.
crontab:System's heartbeat and scheduling officer
Next, let's take a look atcrontabThis is a tool used to set periodic execution tasks in Linux/Unix systems. If Nginx is the facade of a website, thencrontabIt is the "heartbeat monitor" and "backstage service soldier" of the website.
crontabThe key role in the manual deployment of AnQiCMS is reflected in:
- Ensure the continuous operation of the application (heartbeat mechanism):AnQiCMS is an independent executable file written in Go.Although Go programs are usually very stable, any application may crash and stop due to various unforeseen reasons (such as resource exhaustion, code exceptions, server fluctuations, etc.).If AnQiCMS stops running, the entire website will become inoperative.
crontabcome into play. By configuring a timer task that runs every minute (or more frequently), we can write a simple script (such as the one mentioned in the document)start.shIt will check if the AnQiCMS process exists.If not present, the script will automatically restart AnQiCMS.So, even if the application crashes unexpectedly, it can recover automatically in a short period of time, greatly improving the availability and stability of the website.This is like installing an 'auto-rescue' mechanism for your website, ensuring it stays online at all times. - Scheduling the background scheduled task of AnQiCMS:AnQiCMS as a content management system has many background functions that need to be scheduled to run, such as:
- Scheduled publishing feature:The user may have set the article to be published automatically in the future, which requires the backend to have a mechanism to trigger it.
- Link push:Actively push new content to search engines (such as Baidu, Bing) to accelerate the inclusion.
- Sitemap generation and update:Regularly generate or update the sitemap to help search engines better crawl the website structure.
- Content collection and batch import:If an automatic collection task is configured, it needs to be triggered regularly.
- Data statistics and cleaning:The summary of flow statistics data, regular cleaning of old logs or recycle bin contents, etc.The 'Time Factor - Scheduled Release Function' and 'Scheduled Task Function' mentioned in the document both explicitly state that AnQiCMS requires background task support.
crontabIt is the ideal tool to perform these tasks, which can accurately and correctly trigger the corresponding functional modules of AnQiCMS according to the preset schedule.
Therefore,crontabNot only is it the guardian to ensure the uninterrupted operation of AnQiCMS core services, but also the scheduler for the automated execution of its rich content operation functions.
Both play a critical role: indispensable partners
Now, we can clearly see the Nginx reverse proxy andcrontabThe correlation and collaboration between timed tasks:
- Nginx allows your AnQiCMS website to be accessed from outside and optimizes the access experience;
crontabEnsure that the AnQiCMS application is always online and all scheduled tasks are executed as planned.
They are two indispensable dimensions for the normal operation of the website. If there is only Nginx without configurationcrontabTo guard the AnQiCMS process, once the AnQiCMS application crashes, the website will be inaccessible for a long time, and Nginx can only helplessly return an error page. Conversely, if only the configuration ofcrontabTo start AnQiCMS, but without Nginx reverse proxy, then AnQiCMS can only be accessed within the server even if it runs perfectly, and the public still cannot reach it.
可以说,Nginx提供了网站的“可见性”和“前端性能”,而crontabIt ensures the "back-end availability" and "function integrity" of the website.Only both working closely together can provide you with a stable, efficient, and feature-rich online service for your AnQiCMS website.Understanding and properly configuring them is a core skill that every AnQiCMS operator and technical maintainer should master.
Common Questions (FAQ)
Q: Why can't I access the website through the domain name even though I manually deployed AnQiCMS and the program has started? A:This is usually because you have not configured the Nginx reverse proxy correctly.AnQiCMS usually runs on non-standard ports (such as 8001), while the browser accesses the domain name using the default ports 80 or 443.Nginx acts as a reverse proxy, responsible for listening to these standard ports and forwarding requests to the internal ports of AnQiCMS.If there is no Nginx or configuration error, external requests cannot reach AnQiCMS, resulting in the website being inaccessible.
Q: If I don't set anything for AnQiCMS
crontabWhat are the effects of the scheduled task guarding the process? A:The greatest impact is that the stability and reliability of the website will be significantly reduced.AnQiCMS as an independent Go program, although robust, may still crash unexpectedly due to various reasons (such as exhaustion of system resources, program bugs, sudden traffic surges, etc.).crontabThe timing check and automatic restart mechanism, once the program crashes, the website will remain offline until you manually intervene to restart.In addition, many background functions in AnQiCMS that depend on scheduled execution (such as scheduled publication, search engine link push, Sitemap update, etc.) will also not be executed on time, which will seriously affect the efficiency of content operation and SEO effects.Q: Can I deploy multiple AnQiCMS sites on a single server, and each site uses an independent Nginx reverse proxy and
crontabtask? A:It is absolutely fine. AnQiCMS supports multi-site management, you can access it throughconfig.jsonConfiguring different port numbers for each AnQiCMS instance to distinguish them. Then, in Nginx, configure an independent port for each domain.serverBlocks, respectively reverse proxy to the corresponding AnQiCMS instance ports. As forcrontab,You need to configure for each AnQiCMS instance (if they are independent Go executable files) or each site (if they are all managed by one AnQiCMS main program but require different background task strategies)start.shScript and scheduling tasks, ensure they are monitored and executed independently. The document also mentions the deployment method of "installing multiple sites on a single server", Nginx andcrontabThe independent or shared configuration needs to be determined according to the specific deployment architecture.
