1.查看软件包是否安装
[root@rrcy ~]# rpm -qa |grep ssl
nss_compat_ossl-0.9.6-1.el6.x86_64
openssl-1.0.1e-16.el6_5.7.x86_64
openssl-devel-1.0.1e-16.el6_5.7.x86_64
mod_ssl-2.2.15-30.el6.centos.x86_64
2.切换到CA目录
[root@rrcy ~]# cd /etc/pki/CA/
[root@rrcy CA]# ls
certs crl newcerts private
[root@rrcy CA]# pwd
/etc/pki/CA
3.创建一个rsa 私钥 2048位
cakey.pem
[root@rrcy CA]# (umask 077;openssl genrsa -out private/cakey.pem 2048)
Generating RSA private key, 2048 bit long modulus
............................................................................................+++
..............................+++
e is 65537 (0x10001)
权限600
[root@rrcy CA]# ls -l private/cakey.pem
-rw------- 1 root root 1679 Jul 28 14:32 private/cakey.pem
4.生成自签证书
[root@rrcy CA]# vim ../tls/openssl.cnf
修改countryName_default = XX 默认国家名字CN
修改stateOrProvinceName_default = Fujian 默认省会名称
localityName_default = Fuzhou 城市名称
0.organizationName_default = MageEdu 组织名称
organizationalUnitName_default = Tech 部门名称
[root@rrcy CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days 3655
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) [Fujian]:
Locality Name (eg, city) [Fuzhou]:
Organization Name (eg, company) [MageEdu]:
Organizational Unit Name (eg, section) [Tech]:
Common Name (eg, your name or your server‘s hostname) []:ca.magedu.com
Email Address []:admin@magedu.com
[ CA_default ]
dir = /etc/pki/CA
5.创建证书
[root@rrcy CA]# cd /etc/httpd/
[root@rrcy httpd]# ls
conf conf.d logs modules run
[root@rrcy httpd]# mkdir ssl
[root@rrcy httpd]# ls
conf conf.d logs modules run ssl
[root@rrcy httpd]# cd ssl/
[root@rrcy ssl]# (umask 077;openssl genrsa 1024 >httpd.key)
Generating RSA private key, 1024 bit long modulus
................++++++
..................++++++
e is 65537 (0x10001)
[root@rrcy ssl]# ll
total 4
-rw------- 1 root root 887 Jul 28 14:49 httpd.key
[root@rrcy ssl]# openssl req -new -key httpd.key -out httpd.csr

An optional company name []:
[root@rrcy ssl]# ls
httpd.csr httpd.key
6.颁发证书
[root@rrcy ssl]# openssl ca -in httpd.csr -out httpd.crt -days 3650
Using configuration from /etc/pki/tls/openssl.cnf
Check that the request matches the signature
