yum install -y httpd
yum install -y mod_ssl
#防火墙打开80、443端口，然后重启
firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --zone=public --add-port=443/tcp --permanent
firewall-cmd --reload
#Apache开启
systemctl enable httpd
systemctl start httpd

vim /etc/httpd/conf/httpd.conf

#HTTP --> HTTPS
RewriteEngine on
RewriteCond %{SERVER_PORT} !^443$　　　　　　#另一种写法：RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L] 　　#301表示永久移走
