I have been trying to host a simple Wordpress blog using NGINX as the web-server. The blog is hosted as a subdirectory under domain_name.com/blog.
The main blog opens up correctly. But when trying to open the wp-admin under domain_name.com/blog/wp-admin my browser shows ERR_TOO_MANY_REDIRECTS.
I am not sure if this is an issue with my NGINX configuration or wordpress configuration. Following is my NGINX server block:
server {
listen 80;
server_name <domain_name.com>;
root /var/www/html;
index index.php;
location /blog {
try_files $uri $uri/ /blog/index.php?$args;
}
location ~ \.php$ {
include fastcgi.conf;
fastcgi_intercept_errors on;
fastcgi_pass php;
}
location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
expires max;
log_not_found off;
}
}
Wordpress is installed under the /var/www/html/blog directory. And the values for "siteurl" and "home" wp_options in the database are both pointing to domain_name.com/blog.
What would be a good way to solve this problem?
Additional notes that might be helpful: When I try to access static files under the wp-content directory, they open without any issues. No redirection errors there.

It is usual for WordPress to redirect an http session to https whenever accessing wp-admin. This may be controlled using the FORCE_SSL_LOGIN and FORCE_SSL_ADMIN settings in wp-config.php.
When a reverse proxy is terminating SSL, the fact that the originating connection is over https must be conveyed to WordPress to avoid a redirection loop.
Your reverse proxy should be setting headers such as X-Forwarded-Proto.
You need to change your nginx configuration so that the HTTPS flag is set correctly for WordPress.
For example:
map $http_x_forwarded_proto $https_flag {
default off;
https on;
}
server {
listen 80;
server_name example.com;
root /var/www/html;
index index.php;
location /blog {
try_files $uri $uri/ /blog/index.php?$args;
}
location ~ \.php$ {
include fastcgi.conf;
fastcgi_intercept_errors on;
fastcgi_param HTTPS $https_flag;
fastcgi_pass php;
}
location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
expires max;
log_not_found off;
}
}
