利用openssl命令搭建私有CA管理证书

工具

1、创建所需要的文件

touch /etc/pki/CA/index.txt 生成证书索引数据库文件
echo 01 > /etc/pki/CA/serial 指定第一个颁发证书的序列号

2、CA自签证书

[root@centos7 ~]#cd /etc/pki/CA/

[root@centos7 CA]#(umask066; openssl genrsa -out /etc/pki/CA/private/cakey.pem -des3 2048) //生成私钥
bash: umask066: command not found...
Generating RSA private key, 2048 bit long modulus
..................+++
..+++
e is 65537 (0x10001)
Enter pass phrase for /etc/pki/CA/private/cakey.pem:

[root@centos7 CA]#openssl req -new -x509 -key /etc/pki/CA/private/cakey.pem -days  7300 -out cacert.pem //生成自签名证书
Enter pass phrase for /etc/pki/CA/private/cakey.pem:

3、颁发证书

在需要使用证书的主机生成证书请求并生成私钥

[root@centos6 app]#(umask 066;openssl genrsa -out app.key 1024)
Generating RSA private key, 1024 bit long modulus
..++++++
.......................++++++
e is 65537 (0x10001)
You have new mail in /var/spool/mail/root

生成证书申请文件

[root@centos6 app]#openssl req -new -key app.key -days 365 -out app.pem
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]:magedu
Organizational Unit Name (eg, section) []:web
Common Name (eg, your name or your server's hostname) []:*.ifeier.tech
Email Address []:1353250703@qq.com
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

将证书请求文件传输给CA
CA签署证书，并将证书颁发给请求者

注意：默认国家，省，公司名称三项必须和CA一致

[root@centos7 CA]#openssl ca -in app.csr -out certs/app.crt -days 365
Using configuration from /etc/pki/tls/openssl.cnf
Enter pass phrase for /etc/pki/CA/private/cakey.pem:

这就是全部过程，把证书发送到windows里面会看的很清楚！

默认国家，省，公司名称三项有错误的话。

[root@centos6 app]#openssl req -new -key app.key -days 365 -out app2.csr
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) []:HeBei
Locality Name (eg, city) [Default City]:Shijiazhuang
Organization Name (eg, company) [Default Company Ltd]:linux
Organizational Unit Name (eg, section) []:dev
Common Name (eg, your name or your server's hostname) []:www.linux.org
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:

发送给CA申请证书

app2.csr                                                    100%  655     0.6KB/s   00:00

出现错误

[root@centos7 CA]#openssl ca -in app2.csr -out certs/app2_2.crt 
Using configuration from /etc/pki/tls/openssl.cnf
Enter pass phrase for /etc/pki/CA/private/cakey.pem:
Check that the request matches the signature
Signature ok
The stateOrProvinceName field needed to be the same in the
CA certificate (Beijing) and the request (HeBei) //不匹配

这是只能修改配置文件

[root@centos7 CA]#vim /etc/pki/tls/openssl.cnf 
# For the CA policy
# and supplied fields are just that :-)                                    
policy          = policy_match //找到这一行改为 policy_anything

完成

利用openssl命令搭建私有CA管理证书

1、创建所需要的文件

2、CA自签证书

3、颁发证书

4、吊销证书
