私有CA建立和证书申请CA在创建时有规定的格式，详细需要参考/etc/pki/tls/openssl.cnf此文件存放了CA相关的一些配置信息。
以下为比较重要的2个相关配置：
1.此段为CA的详细目录结构
####################################################################
[ ca ]
default_ca = CA_default # The default ca section
####################################################################
[ CA_default ]
dir = /etc/pki/CA # Where everything is kept
certs = $dir/certs # Where the issued certs are kept
crl_dir = $dir/crl # Where the issued crl are kept
database = $dir/index.txt # database index file.
#unique_subject = no # Set to ‘no‘ to allow creation of
# several ctificates with same subject.
new_certs_dir = $dir/newcerts # default place for new certs.
certificate = $dir/cacert.pem # The CA certificate
serial = $dir/serial # The current serial number
crlnumber = $dir/crlnumber # the current crl number
# must be commented out to leave a V1 CRL
crl = $dir/crl.pem # The current CRL
private_key = $dir/private/cakey.pem# The private key
RANDFILE = $dir/private/.rand # private random number file
x509_extensions = usr_cert # The extentions to add to the cert2.此段为证书签署的相关规则，其中标记为match的表示客户端在提交证书签署申请时必须和CA相同的部分。若要不同也可以修改policy规则
# A few difference way of specifying how similar the request should look
# For type CA, the listed attributes must be the same, and the optional
# and supplied fields are just that :-)
policy = policy_match #此处若修改为policy_anything就能实现客户端申请证书时countryName、stateOrProvinceName、organizationName和CA不同也能签署。
# For the CA policy
[ policy_match ]
countryName = match
stateOrProvinceName = match
organizationName = match
organizationalUnitName = optional
commonName = supplied
emailAddress = optional
# For the ‘anything‘ policy
# At this point in time, you must list all acceptable ‘object‘
# types.
[ policy_anything ]
countryName = optional
stateOrProvinceName = optional
localityName = optional
organizationName = optional
organizationalUnitName = optional
commonName = supplied
emailAddress = optional1.生成证书索引数据库文件
[root@centos7 CA]# touch index.txt2.指定证书颁发序列号
[root@centos7 CA]# echo 01 > serial3.生成私钥
私钥必须存放在/etc/pki/CA/private下取名为cakey.pem
[root@centos7 CA]# (umask 066;openssl genrsa -out private/cakey.pem 4096) #生成私钥，指定长度为4096位
Generating RSA private key, 4096 bit long modulus
.........................................++
.....................++
e is 65537 (0x10001)4.生成自签证书
自签证书的存放位置和命名也有规定，必须存放在/etc/pki/CA/下，取名为cacert.pem
[root@centos7 CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days 3650 #生成自签证书，指定有效时长为3650天
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) []:ops
Common Name (eg, your name or your server‘s hostname) []:ca.magedu.com
Email Address []:1.在客户端生成私钥文件
客户端的私钥一般在需要生成私钥的应用下生成
[root@centos7 data]# (umask 066;openssl genrsa -out test.key 1024)
Generating RSA private key, 1024 bit long modulus
....................................................................................................................++++++
.....++++++
e is 65537 (0x10001)2.利用私钥生成证书签署请求
签署请求中Country Name、State or Provice Name、Organization Name必须相同。
[root@centos7 data]# openssl req -new -key test.key -out test.csr
