apache服务器配置http自动跳转到https

第一步

默认情况下，apache的80端口网站目录是/var/www/html
查找配置文件并修改/etc/httpd/conf/httpd.conf
利用伪静态功能

Possible values for the Options directive are "None", "All",

or any combination of:

Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews

Note that "MultiViews" must be named explicitly --- "Options All"

doesn't give it to you.

The Options directive is both complicated and important. Please see

http://httpd.apache.org/docs/2.2/mod/core.html#options

for more information.

Options Indexes FollowSymLinks

AllowOverride controls what directives may be placed in .htaccess files.

It can be "All", "None", or any combination of the keywords:

Options FileInfo AuthConfig Limit

AllowOverride All   #原来是None，需要改成All

Controls who can get stuff from this server.

Order allow,deny
Allow from all

第二步

然后在需要跳转的网站根目录，也就是80端口的网站根目录/var/www/html下创建一个.htaccess文件，如果目录下已经有.htaccess文件，则用vi或者其他编辑器打开，在最下面添加写入如下语句即可
RewriteEngine on
RewriteBase /
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [L,R]
保存，重启httpd服务，再次访问http://域名，发现会直接跳转到https://域名
配置成功。
