Table 3 lists the verified Nginx versions and supported OS versions.

If Nginx 1.14.2 on CentOS 7.6 is used, it is a good practice that you use the dedicated software porting function of the Kunpeng Porting Advisor to port it to the Kunpeng platform. For details, see Dedicated Software Porting. You can refer to this document for the porting as well.
