What does nginx405 error mean

The 405 error indicates that the server received an unsupported HTTP request method issued by the client. The solution is to check the server documentation or use the HTTP request testing tool to determine the correct request method. Errors usually occur when the client uses incompatible methods (such as POST accessing GET resources) or when the server is configured incorrectly.

When you see an Nginx 403 error, it means that the server prohibits you from accessing the resource because of permission issues, file type restrictions, directory browsing disabled, IP address restrictions, or firewall rules. To resolve this issue, please contact the website administrator or server owner to: 1) grant permissions; 2) change file type restrictions; 3) enable directory browsing; 4) remove your IP address from the restricted list; 5) change firewall rules.

What is the difference between nginx and zookeeper

Nginx is used for web servers, while ZooKeeper is used for distributed coordination services. Nginx adopts a single-process, event-driven architecture, while ZooKeeper adopts a distributed, leader-follower architecture. Nginx stores web server configuration data, and ZooKeeper stores cluster membership, configuration, and lock services. Nginx supports horizontal scaling, while ZooKeeper is deployed in the cluster. Nginx mainly supports HTTP, HTTPS and WebSocket protocols, and ZooKeeper uses the custom protocol Zooko to communicate.

How to use nginx

Nginx is a high-performance open source web server. Here are the steps to use it: Install Nginx: Install based on the operating system, such as Linux, macOS, or Windows. Configuration Nginx: Edit the main configuration file, define the listening address, set the root directory and index file. Start Nginx: Use system commands to start the service. Test Nginx: Send HTTP requests to verify that they work properly.

Is nginx a server?

Yes, nginx is a lightweight, high-performance web server. It is mainly used for: 1. Handling HTTP and HTTPS requests; 2. Reverse proxy requests; 3. Cache common resources; 4. Encrypt connections; 5. Optimize load balancing.

nginx monitoring configuration file

Nginx Monitoring Configuration File: events block: Controls connection processing, such as concurrency and multi-receive mechanisms. http block: Configure access logs, error logs, and performance-related settings. server block: Defines the virtual host, including the listening port, host name, and root directory. location block: Used for request forwarding (such as proxy and FastCGI), as well as cache configuration. Monitoring module: ngx_http_stub_status_module provides server status information, ngx_http_server_tokens_module adds server header.

nginx listener port 80

To make nginx listen to port 80, you need to modify the listen instruction in the configuration file to listen 80, and check the user permissions to ensure that you have root permissions. Finally, reload nginx and verify that the listening port is correct.

nginx listens to forward different applications on the same port

Nginx can be configured to listen to the same port and forward traffic to different applications based on request: create a virtual host configuration, specify the port and server name. Use the proxy_pass directive to set the forwarding target in the location block. Start a different application and make sure it is listening for incoming connections. Test the configuration, navigate to a different server name to verify traffic forwarding.

NGINX listens to domain names, not to listen to ports

In order for NGINX to listen to domain names without listening to ports, it is necessary to configure it in the configuration file: 1. Configure the virtual host and specify the domain name to listen to; 2. Delete the default listening port; 3. Configure DNS resolution; 4. Restart NGINX. This way, NGINX will only listen to the domain name, improve security and enable SNI.
