RewriteEngine on                              # 开启重定向擎设置为on，就是让url重写生效
RewriteCond %{SERVER_PORT} !^443$                # 设置规则，端口重定向成 443 端口
RewriteRule ^(.*)?$ https://%{SERVER_NAME}/$1 [L,R]  # ^(.*)?$是一个正则表达式，意思是对所有请求都重定向到https://....


其它代码解释

RewriteCond %{REQUEST_FILENAME} !-f          #如果文件存在，就直接访问文件，不进行下面的RewriteRule.

RewriteCond %{REQUEST_FILENAME} !-d          # 如果目录存在就直接访问目录不进行RewriteRule

RewriteCond $1 !^(index\.php|images|robots\.txt)    #配置url重写规则，!^(index\.php|images|robots\.txt) 这个正则表达式指明了哪些文件不需要重                                                         写，而是直接访问；

vim /etc/httpd/conf/httpd.conf    # 添加如下内容
