主机名解析
Linux 和MAC系统中修改 /etc/host
windows主机名解析 在C:\windows\system32\drivers\etc\hosts找到文件无法修改，需要把文件拖到桌面修改，添加解析，再放回原位
7、配置https步骤
https（全称：Hyper Text Transfer Protocol over SecureSocket Layer），是以安全为目标的 http 通道，在 http 的基础上通过传输加密和身份认证保证了传输过程的安全性。
1. mod_ssl模块
mod_ssl 模块可以实现https加密认证。
//安装mod_ssl模块
[root@localhost ~]# dnf install -y mod_ssl
a).CACA生成一对密钥
[root@localhost ~]# mkdir /etc/pki/CA
[root@localhost ~]# cd /etc/pki/CA
[root@localhost CA]# mkdir private
[root@localhost CA]# (umask 077;openssl genrsa -out private/cakey.pem 2048) #生成密钥
Generating RSA private key, 2048 bit long modulus (2 primes)

....................................................+++++
e is 65537 (0x010001)
[root@localhost CA]# openssl rsa -in private/cakey.pem -pubout #提取公钥

b). CA生成自签署证书
[root@localhost CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days 365 #生成自签署证书
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.
