Which lua-nginx-module version do you use?

[oliveryunchang]

test on the latest slardar, lua-nginx-module version is 0.10.6rc1

[yejingx]

@0904681074 You must compile Nginx with openssl before you can use tcpsocket:sslhandshake. You can add --with-openssl or set your own openssl path here.

Thanks a lot!

--with-http_ssl_module or --with-openssl=openssl_path
