How to bind domain name and set root directory to nginx server

It is very convenient for the nginx server to bind the domain name and set the root directory. First, enter the nginx installation directory, then execute vimconf/nginx.conf to open the nginx configuration file, and find the code snippet of server{........}, here The code snippet is used to configure the corresponding site. First, we should resolve the domain name to the IP address of our server in the domain name control panel, and then the binding can take effect. First, find the server_name item in our code snippet and then add the following domain name. Change it to the domain name we want to bind. Root is the specified root directory. Just set it to the directory we specify. What if we want to bind multiple domain names?

How to set up Nginx and Tomcat servers to achieve load balancing under Debian

The basic concept of load balancing Load balancing (loadbalancing) is a computer network technology used to distribute load among multiple computers (computer clusters), network connections, CPUs, disk drives or other resources to achieve optimal resource usage. The purpose is to maximize throughput, minimize response time, and avoid overload. Using multiple server components with load balancing instead of a single component can improve reliability through redundancy. Load balancing services are usually performed by specialized software and hardware. One of the most important applications of load balancing is the use of multiple servers to provide a single service. This solution is sometimes called a server farm. Usually, load balancing is mainly used in web websites, large-scale Internet

How to implement Nginx reverse proxy to support long connections

Preface The connection between nginxupstream and the backend is a short connection by default. It initiates a connection to the backend through http/1.0 and sets the "connection" header of the request to "close". The connection between nginx and the front end is a long connection by default. After a user establishes a connection with nginx, he sends multiple requests through this long connection. If nginx is only used as a reverseproxy, one user connection may require multiple short connections to the backend. If the back-end server (origin site or cache server) is not strong enough to handle concurrent connections, bottlenecks may occur. nginx current upst

What are the characteristics and differences between Nginx and Apache

1. Nginx features 1. It is lightweight and written in C. The same web service will occupy less memory and resources. 2. Anti-concurrency, nginx uses epollandkqueue as the development model, processing requests is asynchronous and non-blocking, and the load capacity is much higher than that of apache, while apache is blocking. Under high concurrency, nginx can maintain low resource consumption and high performance, while apache is prone to a surge in the number of processes and denial of service when PHP processing is slow or the front-end pressure is high. 3. When nginx is started, it will generate a master process. Then, the master process will fork multiple worker sub-processes. Finally, each user's

Nginx service optimization methods

Nginx service optimization can be optimized from several aspects: hiding version numbers, changing users and groups, configuring web page cache time, log cutting, and setting connection timeouts. 1. Hidden version number In the production environment, the version number of Nginx needs to be hidden to avoid leaking the Nginx version and preventing attackers from conducting attacks on specific versions. To check the Nginx version, use the command curl-Ihttp://172.16.10.10/ in CentOS. [[emailprotected]~]#curl

What are the methods to optimize Nginx performance?

Nginx performance optimization 1. Number of Nginx running working processes The number of Nginx running working processes is generally set to the CPU core or the number of cores x 2. If you don’t know the number of cores of the CPU, you can press 1 after the top command to find out, or you can check the /proc/cpuinfo file grep^processor/proc/cpuinfo|wc-l[root@lx~]#vi/usr/local/nginx1 .10/conf/nginx.confworker_processes4;[root@lx~]#/usr/local/nginx1.10/sbin/nginx-sreloa
