NGINX Plus Technical Specifications
NGINX Plus is available in binary form only; it is not available in source form. Please inquire for additional platforms and modules.
Supported Distributions
Ubuntu
- 16.04 LTS (x86_64, aarch64, ppc64le)
- 18.04 LTS (x86_64, aarch64)
- 20.04 (x86_64, aarch64)
Notes:
- NGINX Controller users: some distributions are not supported by the NGINX Controller Agent. See the NGINX Controller Tech Specs.
nginx-ha-keepaliveandnginx-syncmodules not supported in Alpine Linux.
Dynamic Modules
Except as specified below, dynamic modules are supported on the same distributions as NGINX Plus.
Brotli
- Alpine Linux: Not supported
- Amazon Linux/Amazon Linux 2: Not supported
- CentOS/RHEL 7.4+: Not supported
- Debian 9, 10: Not supported
- Oracle Linux: Not supported

Supported SSL/TLS Versions
NGINX Plus supports SSLv2, SSLv3, TLSv1, TLSv1.1, TLSv1.2, and TLSv1.3. Configure the choice of enabled protocols with the ssl_protocols directive.
TLSv1.2 and earlier is supported on all the operating systems listed in Supported Distributions.
NGINX Plus R17 and later support TLSv1.3. However, not all operating systems supported by NGINX Plus ship with OpenSSL 1.1.1 as required to support TLSv1.3. To determine if an operating system supports TLSv1.3, consult the vendor documentation.
Supported Deployment Environments
