　　建立SSL证书

　　；；建几个目录和文件

　　mkdir /usr/local/myssl

　　cd /usr/local/myssl

　　mkdir private newcerts

　　touch index.txt

　　echo "01" > serial

　　；；拷贝一份OpenSSL的缺省配置到当前目录

　　cp /usr/local/openssl/openssl.cnf .

　　；；修改当前目录下的openssl.cnf，将。/demoCA替换为/usr/local/myssl，replace的具体用法见man

　　replace ./demoCA /usr/local/myssl —— /usr/local/myssl/openssl.cnf
