生成 ssl/自签名 证书
生成 key
# 生成rsa私钥des3算法server_ssl.key是秘钥文件名 1024位强度
openssl genrsa -des3 -out server_ssl.key 1024让输入两次密码随便但是两次得是一样的
移除密码
# 这里执行完上一步的密码即已经被移除了
openssl rsa -in server_ssl.key -out server_ssl.key生成 csr
# -new 执行生成新的证书请求
# -key 指定密钥
openssl req -new -key server_ssl.key -out server_ssl.csrCountry Name (2 letter code) [国家]:CN State or Province Name (full name) [省份]:Beijing Locality Name (eg, city) [城市]:Beijing Organization Name (eg, company) [组织/公司]:zgp Organizational Unit Name (eg, section) [部门/单位]:zgp Common Name (eg, fully qualified host name) [域名]:test.zgp.cn Email Address [邮箱]:demooutlook.com Please enter the following ‘extra’ attributes to be sent with your certificate request A challenge password [上一步已经移除直接回车即可]:
生成证书
# x509 根据现有的证书请求生成自签名根证书
# -days 设置证书的有效天数
# -in 指定输入证书请求文件
openssl x509 -req -days 365 -in server_ssl.csr -signkey server_ssl.key -out server_ssl.crt执行过程截图 创建 nodejs 的 https/wss 服务
创建 express 项目就不多说了自行查看nodejsexpress自动生成项目 express 文档地址https://www.expressjs.com.cn/starter/generator.html
修改的 bin/www 文件
