[英]How apache reverse proxy can be configured without breaking the https tunnel between client & server?
[英]Error configuring a HTTPS forward proxy (AH02268: downstream server wanted client certificate but none are configured)
我想我一起犯了幾個錯誤,但我被困住了,我要瘋了。 而且我猜這個問題已經提出了,但是,即使搜索了很多,我也找不到這個確切的案例發布在任何地方。
我正在做的任務是通過代理調用遠程 HTTPS 服務器:
wget http://localhost/remote?wsdl
指着
https://someserver.com/service?wsdl
在圖表中:
(http) (https)
client ------> localhost -------> someserver.com
使用出色的 Apache web 服務器(真的,不是開玩笑)。
證書交換發生在代理和遠程服務器之間,我已經使用代理板載的私鑰安裝了客戶端證書。 客戶在.p12
文件中給了我證書。
嘗試使用SoapUI
和相同的證書測試所需的 web 服務,我得到了預期的行為(一切正常)。 但是現在我必須從中間件調用服務。 為此,我正在使用 Apache 配置 SSL 代理。
我嘗試以兩種方式做到這一點,但均不成功:
1)在兩個文件中分別定義一個proxy和定義SSL參數:
/etc/apache2/conf.d/mods-available/ssl.conf
/etc/apache2/conf.d/mods-available/proxy.conf
第一個文件包含:
# /etc/apache2/conf.d/mods-available/ssl.conf
SSLPassPhraseDialog exec:/usr/local/etc/apache2/pwf.sh # to avoid manuallly entering passphrase
SSLSessionCache shmcb:/var/cache/mod_ssl/scache(512000)
SSLSessionCacheTimeout 300
SSLRandomSeed startup file:/dev/urandom 256
SSLRandomSeed connect builtin
ErrorLog /var/log/ssl_error_log
TransferLog /var/log/ssl_access_log
LogLevel warn
SSLEngine off
SSLProtocol all -SSLv2
SSLCipherSuite DEFAULT:!EXP:!SSLv2:!DES:!IDEA:!SEED:+3DES
SSLCertificateFile /usr/local/etc/apache2/ssl.crt/certificate.pem
SSLCertificateKeyFile /usr/local/etc/apache2/ssl.key/server.key
SSLCertificateChainFile /usr/local/etc/apache2/ssl.crt/chain.pem
CustomLog /var/log/ssl_request_log "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"
第二個文件包含:
# /etc/apache/conf.d/mods-available/proxy.conf
SetEnv proxy-sendcl 1
SSLProxyEngine On
ProxyPass /remote https://someserver.com/service
ProxyPassReverse /remote https://someserver.com/service
我通過以下方式啟用了這些模塊:
sudo a2enmod proxy & a2enmod ssl
2) 定義虛擬主機
/etc/apache2/conf.d/sites-available/remote.conf
此方法與前一種方法互斥:
#
# remote.local
<VirtualHost SOMEIP:443>
ProxyRequests on
DocumentRoot /var/www/html/remote
ServerName someserver.com
SSLEngine on
SSLProxyEngine on
SSLCertificateFile /usr/local/etc/apache2/ssl.crt/certificate.pem
SSLCertificateKeyFile /usr/local/etc/apache2/ssl.key/server.key
SSLCertificateChainFile /usr/local/etc/apache2/ssl.crt/chain.pem
ProxyPreserveHost On
ErrorLog ${APACHE_LOG_DIR}/error_remote.log
CustomLog ${APACHE_LOG_DIR}/access_remote.log combined
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel info
<Location /remote>
ProxyPass https://someserver.com/service
ProxyPassReverse https://someserver.com/service
Order allow,deny
Allow from all
</Location>
</VirtualHost>
我啟用了這個:
sudo a2ensite remote
在我嘗試的兩種方法中的任何一種中,當我嘗試訪問本地 URL 時都會收到這些(相同的)錯誤:
[Thu Jun 11 18:39:15.724705 2020] [ssl:warn] [pid 30578] AH02268: Proxy client certificate callback: (localhost:80) downstream server wanted client certificate but none are configured
[Thu Jun 11 18:39:15.794381 2020] [proxy_http:error] [pid 30578] (20014)Internal error (specific information not available): [client ::1:49118] AH01102: error reading status line from remote server someserver.com:443
[Thu Jun 11 18:39:15.794585 2020] [proxy:error] [pid 30578] [client ::1:49118] AH00898: Error reading from remote server returned by /remote/
證書鏈沒問題:
openssl crl2pkcs7 -nocrl -certfile chain.pem | openssl pkcs7 -print_certs -noout
向我顯示 CA、中間和服務器證書的所有證書頒發者和主題:
openssl verify -CAfile ca.pem -untrusted chain.pem certificate.pem
certificate.pem: OK
任何建議將不勝感激,在此先感謝。
我錯過了為反向代理配置證書,即部分
SSLProxyMachineCertificateFile
