Example of setting up a whitelist in Nginx using the geo module
|
Original configuration:
http {
......limit_conn_zone $binary_remote_addr zone=one:10m; limit_req_zone $binary_remote_addr zone=fifa:10m rate=5r/s;
......
server {
......
limit_conn one 5;
limit_req zone=fifa burst=100;
......
}}Whitelist configuration:
http {
......
geo$whiteiplist {
default 1;
127.0.0.1 0;
10.10.0.0/24 0;
}
map $whiteiplist $limit {
1 $binary_remote_addr;
0 "";
}
limit_conn_zone $limit zone=one:10m;
limit_req_zone $limit zone=fifa:10m rate=5r/s;
......
server {
......
limit_conn one 5;
limit_req zone=fifa burst=100;
......
}}illustrate: The geo directive defines a whitelist $whiteiplist, the default value is 1, and all are restricted. If the client IP matches the IP listed in the whitelist, the $whiteiplist value is 0, which means no restriction. The map instruction maps the $whiteiplist value to 1, that is, the restricted IP, to the client IP. Map the $whiteiplist value of 0, that is, the whitelist IP, to an empty string. Limit_conn_zone and limit_req_zone directives with empty keys will be ignored, so there is no limit on the listed IPs. The above example of Nginx setting whitelist through geo module is all I want to share with you. I hope it can give you a reference. I also hope that you will support 123WORDPRESS.COM.
