Nginx配置HTTPS证书网站

共计 5104 个字符，预计需要花费 13 分钟才能阅读完成。

前提：

1、主机要先安装 openssl

2、编译安装 nginx 时，要加上 –with-openssl 和 –with-http_ssl_module

1、生成自签字证书
[root@101 /]# openssl req -new -x509 -keyout /root/ca.key -out /root/ca.crt
Generating a 2048 bit RSA private key
………….+++
……………………………..+++
writing new private key to ‘/root/ca.key’
Enter PEM pass phrase: #输入密钥保护密码
Verifying – Enter PEM pass phrase: #确认密码保护密码
—–
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 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) []:guangzhou
Locality Name (eg, city) [Default City]:guangzhou
Organization Name (eg, company) [Default Company Ltd]:linuxidc
Organizational Unit Name (eg, section) []:it
Common Name (eg, your name or your server’s hostname) []:101.linuxidc.com
Email Address []:root@linuxidc.com

2、修改配置文件 openssl.cnf

vim /etc/pki/tls/openssl.cnf
[ca]
default_ca = CA_default # The default ca section

####################################################################
[CA_default]

dir = /etc/pki/CA #证书的根目录，要记住这个目录
certs = $dir/certs
crl_dir = $dir/crl
database = $dir/index.txt
#unique_subject = no

new_certs_dir = $dir/newcerts

certificate = $dir/ca.crt # 修改这里，表示签名时使用的证书
serial = $dir/serial
crlnumber = $dir/crlnumber

crl = $dir/crl.pem
private_key = $dir/private/cakey.pem
RANDFILE = $dir/private/.rand

3、复制证书到证书根目录 /etc/pki/CA 下, 并在该目录下创建空文件 index.txt 和 serial，并向 serial 输入”01“
cd /etc/pki/CA
cp /root/ca.crt .
touch index.txt
touch serial
echo “01” >serial

4、生成服务器 RSA 私钥 /root/server.key

openssl genrsa -des3 -out /root/server.key 1024

5、为私钥去除口令
openssl rsa -in /root/server.key -out /root/server_nopwd.key

5、生成证书请求文件 /root/server.csr
[root@101 /]# openssl req -new -key /root/server.key -out /root/server.csr
Enter pass phrase for /root/server.key: #输入第 4 步生成的密钥的保护密码
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 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.
——– 下面这部分应该和创建私有证书时填的一样 ————————
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:guangzhou
Locality Name (eg, city) [Default City]:guangzhou
Organization Name (eg, company) [Default Company Ltd]:linuxidc
Organizational Unit Name (eg, section) []:it
Common Name (eg, your name or your server’s hostname) []:101.linuxidc.com
—————————————————————-
Email Address []:root@linuxidc.com

Please enter the following ‘extra’ attributes
to be sent with your certificate request
A challenge password []:www.linuxidc.com
An optional company name []:linuxidc

6、用私有证书给证书请求文件 /root/server.csr 签名
[root@101 CA]# openssl ca -in /root/server.csr -out /root/server.crt -cert /root/ca.crt -keyfile /root/ca.key -config /etc/pki/tls/openssl.cnf
Using configuration from /etc/pki/tls/openssl.cnf
Enter pass phrase for ca.key:
Check that the request matches the signature
Signature ok
Certificate Details:
Serial Number: 1 (0x1)
Validity
Not Before: Aug 31 14:09:15 2016 GMT
Not After : Aug 31 14:09:15 2017 GMT
Subject:
countryName = CN
stateOrProvinceName = guangzhou
organizationName = linuxidc
organizationalUnitName = it
commonName = 101.linuxidc.com
emailAddress = root@linuxidc.com
X509v3 extensions:
X509v3 Basic Constraints:
CA:FALSE
Netscape Comment:
OpenSSL Generated Certificate
X509v3 Subject Key Identifier:
18:80:30:B7:C6:11:61:AE:F3:62:9D:D0:33:D9:97:CB:45:5A:31:91
X509v3 Authority Key Identifier:
keyid:DA:99:4B:9B:29:A8:D8:14:54:FA:52:4B:1E:C3:E0:81:C6:A6:EF:42

Certificate is to be certified until Aug 31 14:09:15 2017 GMT (365 days)
Sign the certificate? [y/n]:yes

out of 1 certificate requests certified, commit? [y/n]y
Write out database with 1 new entries
Data Base Updated

7、编辑 nginx 配置文件 /etc/nginx/nginx.conf
——- 在配置文件的特定区域加入 / 修改下面内容
server {
listen 443 ssl; #设置监听的端口
server_name linuxidc;
ssl on;
ssl_certificate /root/server.crt;
ssl_certificate_key /root/server_nopwd.key;

8、重启服务
～～～～完成，在客户端上输入 https://x.x.x.x 即可访问
