網站添加了https證書后,當http方式訪問網站時就會報404錯誤,所以需要做http到https的強制跳轉設置.
一、采用nginx的rewrite方法
1) 下面是將所有的http請求通過rewrite重寫到https上。
例如將所有的dev.wangshibo.com域名的http訪問強制跳轉到https。
下面配置均可以實現:
配置1:
server {
listen 80;
server_name dev.wangshibo.com;
index index.html index.php index.htm;
access_log /usr/local/nginx/logs/8080-access.log main;
error_log /usr/local/nginx/logs/8080-error.log;
rewrite ^(.*)$ https://$host$1 permanent; //這是ngixn早前的寫法,現在還可以使用。
location ~ / {
root /var/www/html/8080;
index index.html index.php index.htm;
}
}
================================================================
上面的跳轉配置rewrite ^(.*)$ https://$host$1 permanent;
也可以改為下面
rewrite ^/(.*)$ http://dev.wangshibo.com/$1 permanent;
或者
rewrite ^ http://dev.wangshibo.com$request_uri? permanent;
================================================================
配置2:
server {
listen 80;
server_name dev.wangshibo.com;
index index.html index.php index.htm;
access_log /usr/local/nginx/logs/8080-access.log main;
error_log /usr/local/nginx/logs/8080-error.log;
return 301 https://$server_name$request_uri; //這是nginx最新支持的寫法
location ~ / {
root /var/www/html/8080;
index index.html index.php index.htm;
}
}
配置3:這種方式適用於多域名的時候,即訪問wangshibo.com的http也會強制跳轉到https://dev.wangshibo.com上面
server {
listen 80;
server_name dev.wangshibo.com wangshibo.com *.wangshibo.com;
index index.html index.php index.htm;
access_log /usr/local/nginx/logs/8080-access.log main;
error_log /usr/local/nginx/logs/8080-error.log;
if ($host ~* "^wangshibo.com$") {
rewrite ^/(.*)$ https://dev.wangshibo.com/ permanent;
}
location ~ / {
root /var/www/html/8080;
index index.html index.php index.htm;
}
}
配置4:下面是最簡單的一種配置
server {
listen 80;
server_name dev.wangshibo.com;
index index.html index.php index.htm;
access_log /usr/local/nginx/logs/8080-access.log main;
error_log /usr/local/nginx/logs/8080-error.log;
if ($host = "dev.wangshibo.com") {
rewrite ^/(.*)$ http://dev.wangshibo.com permanent;
}
location ~ / {
root /var/www/html/8080;
index index.html index.php index.htm;
}
}
二、采用nginx的497狀態碼 (非標准443端口的https情況下使用的強轉配置方式)
497 - normal request was sent to HTTPS
解釋:當網站只允許https訪問時,當用http訪問時nginx會報出497錯誤碼
思路:
利用error_page命令將497狀態碼的鏈接重定向到https://dev.wangshibo.com這個域名上
配置實例:
如下訪問dev.wangshibo.com或者wangshibo.com的http都會被強制跳轉到https
server {
listen 80;
server_name dev.wangshibo.com wangshibo.com *.wangshibo.com;
index index.html index.php index.htm;
access_log /usr/local/nginx/logs/8080-access.log main;
error_log /usr/local/nginx/logs/8080-error.log;
error_page 497 https://$host$uri?$args;
location ~ / {
root /var/www/html/8080;
index index.html index.php index.htm;
}
}
也可以將80和443的配置放在一起:
server {
listen 127.0.0.1:443; #ssl端口
listen 127.0.0.1:80; #用戶習慣用http訪問,加上80,后面通過497狀態碼讓它自動跳到443端口
server_name dev.wangshibo.com;
#為一個server{......}開啟ssl支持
ssl on;
#指定PEM格式的證書文件
ssl_certificate /etc/nginx/wangshibo.pem;
#指定PEM格式的私鑰文件
ssl_certificate_key /etc/nginx/wangshibo.key;
#讓http請求重定向到https請求
error_page 497 https://$host$uri?$args;
location ~ / {
root /var/www/html/8080;
index index.html index.php index.htm;
}
}
如果遇到非標准443端口的https情況下,則http到https的強轉配置就需要使用上面這種497狀態碼的方式了。如下:
server {
listen 9443 ssl;
server_name www.kevin.com;
error_page 497 https://$server_name:9443$request_uri;
ssl_certificate /etc/nginx/cert/kevin.crt;
ssl_certificate_key /etc/nginx/cert/kevin.key;
.........
這樣訪問http://www.kevin.com:9443 就會自動跳轉到https://www.kevin.com:9443。
這種方式直接配置https端口就可以,不需要再配置http端口。
三、利用meta的刷新作用將http跳轉到https
上述的方法均會耗費服務器的資源,可以借鑒百度使用的方法:巧妙的利用meta的刷新作用,將http跳轉到https
可以基於http://dev.wangshibo.com的虛擬主機路徑下寫一個index.html,內容就是http向https的跳轉
將下面的內容追加到index.html首頁文件內
[root@localhost ~]# cat /var/www/html/8080/index.html
<html>
<meta http-equiv="refresh" content="0;url=https://dev.wangshibo.com/">
</html>
[root@localhost ~]# cat /usr/local/nginx/conf/vhosts/test.conf
server {
listen 80;
server_name dev.wangshibo.com wangshibo.com *.wangshibo.com;
index index.html index.php index.htm;
access_log /usr/local/nginx/logs/8080-access.log main;
error_log /usr/local/nginx/logs/8080-error.log;
#將404的頁面重定向到https的首頁
error_page 404 https://dev.wangshibo.com/;
location ~ / {
root /var/www/html/8080;
index index.html index.php index.htm;
}
}
這里分享一個nginx反代tomcat,並且http強制跳轉至https的配置示例(這里訪問http://zrx.wangshibo.com和訪問http://172.29.34.33:8080/zrx/結果是一樣的)
[root@BJLX_34_33_V vhosts]# cat zrx.conf
server {
listen 80;
server_name zrx.wangshibo.com;
index index.html index.php index.htm;
access_log logs/access.log;
error_log logs/error.log;
return 301 https://$server_name$request_uri;
location ~ / {
root /data/nginx/html;
index index.html index.php index.htm;
}
}
[root@BJLX_34_33_V vhosts]# cat ssl-zrx.conf
upstream tomcat8 {
server 172.29.34.33:8080 max_fails=3 fail_timeout=30s;
}
server {
listen 443;
server_name zrx.wangshibo.com;
ssl on;
### SSL log files ###
access_log logs/ssl-access.log;
error_log logs/ssl-error.log;
### SSL cert files ###
ssl_certificate ssl/wangshibo.cer;
ssl_certificate_key ssl/wangshibo.key;
ssl_session_timeout 5m;
location / {
proxy_pass http://tomcat8/zrx/;
proxy_next_upstream error timeout invalid_header http_500 http_502 http_503;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto https;
proxy_redirect off;
}
}
四、通過proxy_redirec方式
解決辦法:
# re-write redirects to http as to https, example: /home
proxy_redirect http:// https://;
