NGINX Reverse proxy and dynamic/static combination

: This article mainly introduces NGINX Reverse proxy and dynamic/static combination. For more information about PHP tutorials, see. NGINX Reverse proxy and dynamic/static combination

I. default polling mode

Benefit: each request is distributed to different backend servers one by one in chronological order. if the backend server is down, it can be automatically removed.

Http {

Include mime. types;

Default_type application/octet-stream;

# Tcp_nopush on;

Keepalive_timeout 65;

# Configure the reverse proxy. The two machines configured can be multiple

Upstream test {

Server 192.168.136.139: 80;

Server 192.168.136.136: 80;

}

Server {

# Port number

Listen 80;

# Domain name

Server_name localhost;

# Access configuration

Location /{

Root html;

Index index.html index.htm;

}

# Objects that encounter an error jump

Error_page 500 502 503 x.html;

# Accessed Directory

Location =/50x.html {

Root html;

}

Location ~ \. Php $ {

Proxy_pass http: // test; cannot be followed by/http: // test /.

}

# Configure Dynamic/static combination

Location ~ . * \. (Html | htm | gif | jpg | jpeg | bmp | png | ico | txt | js | css) $

{

# Access Directory

Root/test/web;

Expires 3d;

}

}

II. weight Round Robin

Specify the round-robin probability. weight is proportional to the access ratio, which is used when the backend server performance is uneven.

For example:

Upstream bakend {

Server 192.168.159.10 weight = 5;

Server 192.168.159.11 weight = 10;

}

III. ip_hash (ip-based hash allocation policy)

Each request is allocated according to the hash result of the access ip address, so that each visitor accesses a backend server at a fixed time, which can solve the session problem.

For example:

Upstream resinserver {

Ip_hash;

Server 192.168.159.10: 8080;

Server 192.168.159.11: 8080;

}

4. fair (third-party) based on service response

Requests are allocated based on the response time of the backend server. requests with short response time are prioritized.

Upstream resinserver {

Server server1;

Server server2;

Fair;

}
