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 []:
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
