Nginx (reverse proxy server) main functions
1. Request for forwarding
nginx gets the client request, and then forwards it to the specific server according to the path matching.
For example, the request address contains eduservice, then forward to port 8001
Client (browser) → → → request → → nginx (port number 9001) → → → forward → → server eduservice (port number 8001)
euoss (port number 8002)
2. Load balancing
nginx gets the client request, and then shares the requests evenly among different services
Client (browser) →→→ Request →→→ nginx (port number 9001) →→→ Load balancing →→→ Cluster edu (port number 8081)
edu (port number 8082)
3. Separation of movement and stillness
Deploy java code, pages, pictures, etc. separately
For example, put the java code part in Tomcat, and then find a server to place static resources (html, pictures, etc.)
In operation, when determining that the access resource is Java code, request tomcat, and when determining that the access content is html, picture..., access the static server.
Configure nginx to implement the function of request forwarding
1. Find nginx configuration file
E:\develop\web\nginx-1.20.2\conf\
2. Configure in
(1) It is best to change the default 80 port of nginx to 81
(2) Configure nginx forwarding rules
~ Indicates regular match
listen Listen to port
server_name Host Name
location Match paths
proxy_pass The address of the server to be forwarded to(3) Specific configuration
http {
server {
listen 81;
......
}，
......
server {
listen 9001;
server_name localhost;
location ~ /eduservice/ {
proxy_pass http://localhost:8001;
}
location ~ /eduoss/ {
proxy_pass http://localhost:8002;
}
}
}3. Modify BASE_API in config/
BASE_API: '"http://localhost:9001"', // Modify the front-end request address tonginxaddress
4. Restart nginx
Use cmd to start nginx. If you close the cmd window, nginx will not stop
- Stop: -s -s -s
- start up:
