自签名证书和CA机构颁发的证书的区别？参考地址：https://blog.csdn.net/jakejohn/article/details/104644213

使用openssl创建自签名证书步骤

生成CA根证书

    1) 创建私钥（rootCA.key）

    2) 创建CA根证书（rootCA.crt）

    3) 安装CA根证书
生成CA自签证书

    1) 创建私钥

    2) 创建CSR

    3) 使用CA根证书签名CSR

生成CA根证书

（1）创建私钥

openssl genrsa -out rootCA.key 2048

（2）创建CA根证书

openssl req -x509 -new -nodes -key rootCA.key -sha256 -days 1024 -out rootCA.crt

输入以下信息：

-----
Country Name (2 letter code) [AU]:CN
State or Province Name (full name) [Some-State]:Beijing
Locality Name (eg, city) []:Beijing
Organization Name (eg, company) [Internet Widgits Pty Ltd]:VMware
Organizational Unit Name (eg, section) []:Euc
Common Name (eg, YOUR name) []:172.16.28.80
Email Address []:[email protected]

（3）安装CA根证书

设置->隐私设置和安全性->安全->管理证书->受信任的根证书颁发机构->导入生成的证书（rootCA.crt）

生成CA自签证书

（1）创建私钥

openssl genrsa -out server.key 2048

（2）编辑openssl.cnf文件，修改 IP.1，IP.2，DNS.1的配置

创建CSR文件，修改yourpath为你的openssl文件路径

openssl req -new -key server.key -out server.csr -config {yourpath}/openssl.cnf -extensions v3_req

注意：此时除Common Name (eg, YOUR name) []外需要输入与创建CA根证书时相同的信息。此处Common Name 应该输入服务器（Server）的Ip或域名（与在浏览器地址栏需要访问的保持一致）

（3）使用CA根证书签名CSR，注意： server.crt 的时间期限（-days）不能超过CA根证书的时间期限

openssl x509 -req -in server.csr -CA rootCA.crt -CAkey rootCA.key -CAcreateserial -out server.crt -days 500 -sha256 -extensions v3_req -extfile openssl.cnf

生成的证书文件

在Nginx配置文件nginx.conf中添加配置信息，ssl_certificate和ssl_certificate_key是生成的密钥文件

    # HTTPS server
    #
    server {
        listen        443 ssl;
        server_name  172.16.28.80;
        ssl_certificate      /home/nginx_key/server.crt;
        ssl_certificate_key  /home/nginx_key/server.key;

        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;

        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers  on;
        #接口地址代理
        location / {
             root   html;
             index  index.html index.htm;
        }
    }

问题：libssl.so.1.1: cannot open shared object file: No such file or directory，使用官网地址下载，安装时间有点长。
