Centos ASP.NET Core SSL 异常：The request with exception: The SSL connection could not be established 解决办法

Centos ASP.NET Core  SSL 异常：The request with exception: The SSL connection could not be established 解决办法

1、查看 OPENSSLDIR 路径

openssl version -a

OpenSSL 1.0.2k-fips  26 Jan 2017
built on: reproducible build, date unspecified
platform: linux-x86_64
options:  bn(64,64) md2(int) rc4(16x,int) des(idx,cisc,16,int) idea(int) blowfish(idx) 
compiler: gcc -I. -I.. -I../include  -fPIC -DOPENSSL_PIC -DZLIB -DOPENSSL_THREADS -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -DKRB5_MIT -m64 -DL_ENDIAN -Wall -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches   -m64 -mtune=generic -Wa,--noexecstack -DPURIFY -DOPENSSL_IA32_SSE2 -DOPENSSL_BN_ASM_MONT -DOPENSSL_BN_ASM_MONT5 -DOPENSSL_BN_ASM_GF2m -DRC4_ASM -DSHA1_ASM -DSHA256_ASM -DSHA512_ASM -DMD5_ASM -DAES_ASM -DVPAES_ASM -DBSAES_ASM -DWHIRLPOOL_ASM -DGHASH_ASM -DECP_NISTZ256_ASM
OPENSSLDIR: "/etc/pki/tls"
engines:  rdrand dynamic 

根据SHELL输出结果，知道OpenSSL的路径为 `/etc/pki/tls`

2、 拷贝CentOS OpenSSL CA 证书

cp /etc/pki/tls/cert.pem /usr/local/openssl/
