Here is my problem,
I need to install a wordpress application on a subdirectory url (“https://test.com/blog/”). Since my whole environment is running on Docker, I decided to do the same with the wordpress app.
To start it as simple as possible, I added the wordpress image to my docker-compose.yml, and made a subdomain (“http://blog.test.com” which was not using https) fall on the application with my nginx reverse proxy.
It worked well and I installed my wordpress like that.
Now I’m trying to migrate this to my initial need and my problem is that everything works “well”, unless I can’t access the admin url (https://test.com/blog/admin) because it keeps redirects on https://test.com/blog/wp-admin and I get a “Too many redirects” error.
Here is my nginx configuration :
server { listen 80 default_server; listen [::]:80 default_server; server_name test.com; return 301 https://$server_name$request_uri;}server { listen 443 ssl default_server; listen [::]:443 ssl default_server; server_name test.com; error_log /var/log/nginx/test_error.log; access_log /var/log/nginx/test_access.log; location /blog/ { auth_basic "Restricted"; auth_basic_user_file /etc/nginx/test-htpasswd; proxy_pass http://127.0.0.1:8090; proxy_http_version 1.1; proxy_buffering off; proxy_read_timeout 90; proxy_connect_timeout 90; proxy_redirect off; proxy_set_header Host $host; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $proxy_connection; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Proto https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Ssl $proxy_x_forwarded_ssl; proxy_set_header X-Forwarded-Port 443; # Mitigate httpoxy attack (see README for details) proxy_set_header Proxy ""; } location / { auth_basic "Restricted"; auth_basic_user_file /etc/nginx/test-htpasswd; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://127.0.0.1:8082; } ssl_certificate /etc/letsencrypt/live/test.com/fullchain.pem; # managed by Certbot ssl_certificate_key /etc/letsencrypt/live/test.com/privkey.pem; # managed by Certbot add_header X-Robots-Tag "noindex, nofollow, nosnippet, noarchive";}I also added the following at the top of wp-config.php file in the wordpress container :
define('FORCE_SSL_ADMIN', true);if($_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'){ $_SERVER['HTTPS'] = 'on'; $_SERVER['SERVER_PORT'] = 443;}define('WP_HOME','https://test.com/blog/');define('WP_SITEURL','https://test.com/blog/');What I noticed is if I try to print the $_SERVER variable by doing
var_dump($_SERVER);
in wp-config.php, there isn’t any of the nginx proxy variables.
Here is the output :
array(42) { ["REDIRECT_STATUS"]=> string(3) "200" ["HTTP_HOST"]=> string(15) "test.com"["HTTP_X_REAL_IP"]=> string(15) "itsmyip"["HTTP_CONNECTION"]=> string(5) "close"["HTTP_CACHE_CONTROL"]=> string(9) "max-age=0"["HTTP_UPGRADE_INSECURE_REQUESTS"]=> string(1) "1"["HTTP_USER_AGENT"]=> string(104) "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.88 Safari/537.36"["HTTP_SEC_FETCH_USER"]=> string(2) "?1"["HTTP_ACCEPT"]=> string(124) "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9"["HTTP_SEC_FETCH_SITE"]=> string(4) "none"["HTTP_SEC_FETCH_MODE"]=> string(8) "navigate"["HTTP_ACCEPT_ENCODING"]=> string(17) "gzip, deflate, br"["HTTP_ACCEPT_LANGUAGE"]=> string(35) "fr-FR,fr;q=0.9,en-US;q=0.8,en;q=0.7"["HTTP_COOKIE"]=> string(547) "_lfa=eyJYYnAxb2FFR2RSazdFZFZqIjoiTEYxLjEuNGFiNTNhYjI1ZWMwNDE3MS4xNTk1OTM2MTk5MjIyIn0%3D; _ga=GA1.2.1198854717.1595936200; _gid=GA1.2.2083987609.1595936200; _hjid=51fe1835-b72b-4957-873f-dc4147a455fc; _hjIncludedInSample=1; _fbp=fb.1.1595936200807.1293959861; __zlcmid=zPjJja34jXiPWc; PHPSESSID=bo5jv9md5j6kmtomigjgi2bdnl; REMEMBERME=VGhpdmVvXENvcmVCdW5kbGVcRW50aXR5XFVzZXI6Y21Gd2FHRmxiQzV3WlhKamFHVmpLM1JsYzNSaGNtTm9hVzFsWkdWQVoyMWhhV3d1WTI5dDoxNjI3NDcyMjI1Ojg5MWY3ZGM1M2QyMmQyNzdiNWI3MjQ5NTY4NThkZWE5MWIxYmU2NjUzM2EzMmQ5Yzc5MzFjOWJmM2E4ZDliNjk%3D" ["PATH"]=> string(60) "/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"["SERVER_SIGNATURE"]=> string(76) "Apache/2.4.38 (Debian) Server at test.com Port 80" ["SERVER_SOFTWARE"]=> string(22) "Apache/2.4.38 (Debian)"["SERVER_NAME"]=> string(15) "test.com"["SERVER_ADDR"]=> string(11) "itsmyip"["SERVER_PORT"]=> string(2) "80"["REMOTE_ADDR"]=> string(15) "itsmyip"["DOCUMENT_ROOT"]=> string(13) "/var/www/html"["REQUEST_SCHEME"]=> string(4) "http"["CONTEXT_PREFIX"]=> string(0) "" ["CONTEXT_DOCUMENT_ROOT"]=> string(13) "/var/www/html"["SERVER_ADMIN"]=> string(19) "webmaster@localhost"["SCRIPT_FILENAME"]=> string(23) "/var/www/html/index.php"["REMOTE_PORT"]=> string(5) "38136"["REDIRECT_URL"]=> string(12) "/blog/"["GATEWAY_INTERFACE"]=> string(7) "CGI/1.1"["SERVER_PROTOCOL"]=> string(8) "HTTP/1.0"["REQUEST_METHOD"]=> string(3) "GET"["QUERY_STRING"]=> string(0) ""["REQUEST_URI"]=> string(12) "/blog/"["SCRIPT_NAME"]=> string(10) "/index.php"["PHP_SELF"]=> string(10) "/index.php"["REQUEST_TIME_FLOAT"]=> float(1595941685.61)["REQUEST_TIME"]=> int(1595941685)["argv"]=> array(0) { } ["argc"]=> int(0) Do you have any idea ?

Actually I found my way through it ! I had an error in my nginx configuration and if anyone is interested, here is my final working configuration :
nginx.conf file (wordpress bloc) :
location /blog/ { proxy_pass http://127.0.0.1:8093/; proxy_http_version 1.1; proxy_buffering off; proxy_read_timeout 90; proxy_connect_timeout 90; proxy_redirect off; proxy_set_header Host $host; proxy_set_header Upgrade $http_upgrade; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Proto https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Port 443; proxy_set_header Proxy ""; }Here is what I added at the top of wp_config.php file of my wordpress container :
define('FORCE_SSL_ADMIN', true);$_SERVER['REQUEST_URI'] = str_replace("/wp-admin/", "/blog/wp-admin/", $_SERVER['REQUEST_URI']);if($_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'){ $_SERVER['HTTPS'] = 'on'; $_SERVER['SERVER_PORT'] = 443;}define('WP_HOME','https://test.com/blog/');define('WP_SITEURL','https://test.com/blog/');Cheers !
