Nginx配置https协议

https协议是Hypertext Transfer Protocol over Secure Socket Layer的简称，它是基于ssl的http通信协议。用于安全的http数据传输。默认使用443端口。https协议需要生成证书，客户端连接上来，需要先安装证书，例如浏览器打开指定的url,会警告是一个不信任的站点，需要将其加入受信任的站点，然后才可以访问。

今天介绍如何利用nginx来配置让服务器支持https协议。nginx默认安装是支持https协议的，只需要我们生成证书，并配置证书就可以使用了。

在linux服务器上可以使用openssl命令直接创建证书具体命令如下。

1、生成服务器私钥key

这一步会提示你输入口令。

[[email protected] nginx]# openssl genrsa -des3 -out server.key 1024
Generating RSA private key, 1024 bit long modulus
............++++++
.............++++++
e is 65537 (0x10001)
Enter pass phrase for server.key:
140713354999712:error:28069065:lib(40):UI_set_result:result too small:ui_lib.c:869:You must type in 4 to 8191 characters
Enter pass phrase for server.key:
Verifying - Enter pass phrase for server.key:
[[email protected] nginx]#

利用生成的key，创建签名请求的证书。

[[email protected] nginx]# openssl req -new -key server.key -out server.csr
Enter pass phrase for server.key:
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:beijing
Locality Name (eg, city) [Default City]:beijing
Organization Name (eg, company) [Default Company Ltd]:xxx
Organizational Unit Name (eg, section) []:linux
Common Name (eg, your name or your server's hostname) []:docker
Email Address []:[email protected]

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:lenovo
An optional company name []:lenovo
[[email protected] nginx]#

2、生成服务器证书crt

使用上述私钥时去除必要的口令

[[email protected] nginx]# cp server.key server.key.org
[[email protected] nginx]# openssl rsa -in server.key.org -out server.key
Enter pass phrase for server.key.org:
writing RSA key
[[email protected] nginx]#

标记证书有效期10年并使用上述key和csr

[[email protected] nginx]# openssl x509 -req -days 3650 -in server.csr -signkey server.key -out server.crt
Signature ok
subject=/C=CN/ST=beijing/L=beijing/O=xxx/OU=linux/CN=docker/[email protected]
Getting Private key
[[email protected] nginx]#

3、配置nginx的配置文件，让其包含新标记的证书和私钥，并开启443端口。

vi /etc/nginx/conf.d/default.conf

4、测试访问.https://192.168.61.150/index.php

第一次访问提示不信任的站点警告。

点击高级，查看证书。
