以下操作在centos 下执行：

cd/opt/ssl 证书制作路径

1）openssl genrsa -des3 -out domain.key 1024

生成RSA密钥(过程需要设置一个密码,记住这个密码)

2）openssl rsa -in domain.key -out domain_nopass.key

拷贝一个不需要输入密码的密钥文件

3）openssl req -new -key domain.key -out domain.csr

这里会提示输入国家,地区组织,email等信息.最重要的一个是"common name",需要与网站域名相同.

[root@localhost ssl]# openssl req -new -key domain.key -out domain.csr

Enter pass phrase for domain.key: ####1) 密码

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 CN.

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 国家

State or Province Name (full name) []:zj 省

Locality Name (eg, city) [Default City]:hz 城市

Organization Name (eg, company) [Default Company Ltd]:tset 机构名称

Organizational Unit Name (eg, section) []:test 单位名称

Common Name (eg, your name or your server's hostname) []:domain.com 网站域名

Email Address []: 邮箱 可以回车

Please enter the following 'extra' attributes

to be sent with your certificate request

A challenge password []: 可以回车

An optional company name []: 可以回车

输入完这些就会生成一个domain.csr文件,提交给ssl提供商的时候就是这个csr文件.当然这里并没有向任何证书提供商申请,而是自己签发证书.

使用上面的密钥和CSR对证书签名

$ openssl x509 -req -days 365 -in domain.csr -signkey domain.key -out domain.crt

备注：这个365 时间可以多写点。

检测nginx是否支持SSL:

$ nginx -V

如果有显示-with-http_ssl_module表示已编译openssl,支持安装ssl.

如果没有,请重新编译安装nginx
