What is Nginx Config Validator?
Nginx Config Validator inspects configuration text for missing semicolons, suspicious directives, structural issues, and common SSL or server-block mistakes. It offers an early review step before a change reaches a running reverse proxy or web server.
How to use Nginx Config Validator
Paste the Nginx configuration and run validation to review syntax, missing semicolons, directive problems, and SSL-related issues.
When is Nginx Config Validator useful?
Nginx Config Validator is useful when changing reverse-proxy, static hosting, SSL, or server-block configuration before reloading Nginx.
Example
A practical example is checking a server block after adding a proxy_pass rule and TLS configuration.
Practical notes
Only Nginx itself can validate the full configuration with installed modules, included files, certificates, permissions, and version-specific directives. Remove private keys, run the native configuration test on the target system, and reload rather than restart when safe. Confirm upstream health immediately after the reload.
