+# 1、创建私钥
+```bash
+ openssl genrsa  -out server.key 2048
+```
+
+# 2、 创建签名请求文件
+```bash
+ openssl req -new -key server.key -out server.csr
+```
+注意，需要输入域名(Common Name (e.g. server FQDN or YOUR name))：
+```bash
+Country Name (2 letter code) [AU]:cn
+State or Province Name (full name) [Some-State]:gd
+Locality Name (eg, city) []:sz
+Organization Name (eg, company) [Internet Widgits Pty Ltd]:company
+Organizational Unit Name (eg, section) []:section
+Common Name (e.g. server FQDN or YOUR name) []:zlm.com
+Email Address []:xiachu@qq.com
+
+Please enter the following 'extra' attributes
+to be sent with your certificate request
+A challenge password []:
+An optional company name []:zlm
+```
+
+# 3、自签名，生成公钥（10年有效期）
+```bash
+openssl x509 -req -days 3650 -in server.csr -signkey server.key -out server.crt
+```
+执行该命令会打印以下信息：
+```bash
+Signature ok
+subject=/C=cn/ST=gd/L=sz/O=company/OU=section/CN=zlm.com/emailAddress=xiachu@qq.com
+Getting Private key
+```
+
+# 4、合并公钥私钥
+```bash
+cat server.crt server.key > ./ssl.pem
+```
+
+# 5、加载证书
+```bash
+./MediaServer -s ./ssl.pem
+```
