centOS系統(tǒng)生成csr
1.查看是否安裝httpd和SSL（如果有就可以進(jìn)行下一步）
[root@localhost ~]# rpm -qa | grep httpd
httpd-tools-2.2.15-47.el6.centos.4.x86_64
[root@localhost ~]# rpm -qa | grep ssl
openssl-1.0.1e-42.el6_7.4.x86_64
openssl-devel-1.0.1e-42.el6_7.4.x86_64
docbook-style-dsssl-1.79-10.el6.noarch
mod_ssl-2.2.15-47.el6.centos.4.x86_64
nss_compat_ossl-0.9.6-1.el6.x86_64
2.生成服務(wù)器私鑰（以abc.cn為例）
[root@localhost /]# cd /opt
[root@local opt]# openssl genrsa -out abc.cn.key 2048
Generating RSA private key, 2048 bit long modulus
...............+++
...............+++
e is 65537 (0x10001)
3.用私鑰server.key文件生成證書(shū)請(qǐng)求文件csr
[root@local opt]# openssl req -new -out abc.cn.csr -sha256 -key abc.cn.key
