Answer 1

我回答了我的問題

OpenSSL> req -x509 -days 365 -newkey rsa：2048 -keyout any.pem -out any.pem

（密碼短語=秘密）

OpenSSL> req-新-key -any.pem -out server.csr

OpenSSL> x509 -req -in server.csr -signkey any.pem -out rootcert.pem

Answer 2

小更新以及如何運行

由於錯誤： 140006379889088:error:02001002:system library:fopen:No such file or directory:crypto/bio/bss_file.c:74:fopen('-any.pem','r')

openssl req -x509 -days 365 -newkey rsa:2048 -keyout any.pem -out any.pem
openssl req -new -key any.pem -out server.csr #no more -any.pem
openssl x509 -req -in server.csr -signkey any.pem -out rootcert.pem
