通过 tls 将日志从 rsyslog 转发到 graylog

  • 772

我正在尝试通过 tls 将日志从 rsyslog 转发到 graylog。

rsyslog 配置：

# make gtls driver the default
$DefaultNetstreamDriver gtls
#
# # certificate files
$DefaultNetstreamDriverCAFile /etc/ssl/rsyslog/ca.pem
$DefaultNetstreamDriverCertFile /etc/ssl/rsyslog/rsyslog-cert.pem
$DefaultNetstreamDriverKeyFile /etc/ssl/rsyslog/rsyslog-key.pem
#
$ActionSendStreamDriverAuthMode x509/name
$ActionSendStreamDriverPermittedPeer graylog.mydomain.com
$ActionSendStreamDriverMode 1 # run driver in TLS-only mode
*.* @@graylog.mydomain.com:6514 # forward everything to remote server

我生成了 rsyslog 文档中描述的必要证书：

certtool --pkcs8 --generate-privkey --outfile ca-key.pem
certtool --pkcs8 --generate-self-signed --load-privkey ca-key.pem --outfile ca.pem

certtool --pkcs8 --generate-privkey --outfile graylog.key.pem 
certtool --pkcs8 --generate-request --load-privkey graylog.key.pem --outfile graylog.request.pem
certtool --pkcs8 --generate-certificate --load-request graylog.request.pem --outfile graylog.cert.pem --load-ca-certificate ca.pem --load-ca-privkey ca-key.pem

certtool --pkcs8 --generate-privkey --outfile rsyslog.key.pem 
certtool --pkcs8 --generate-request --load-privkey rsyslog.key.pem --outfile rsyslog.request.pem
certtool --pkcs8 --generate-certificate --load-request rsyslog.request.pem --outfile rsyslog.cert.pem --load-ca-certificate ca.pem --load-ca-privkey ca-key.pem

灰色日志配置

所有证书文件都在 /etc/ssl/graylog/input-ca/

graylog 输入配置如下：

TLS cert file: /etc/ssl/graylog/input-ca/graylog-cert.pem
TLS private key file: /etc/ssl/graylog/input-ca/graylog-key.pem
TLS Client Auth Trusted Certs: /etc/ssl/graylog/input-ca

但是当 rsyslog 将日志消息推送到 garylog 时，我收到此错误：

任何想法可能是什么问题？

  1. 您必须使用 keytool 将证书导入 java 密钥库。

    keytool -import -alias mygraylogcertificate -file mygraylogcertificate.cer -keystore examplekeystore

    密钥库位置因安装而异。

  2. Best Answer

    确保您的 Graylog 进程可以读取证书文件和密钥。（它通常以“graylog”用户身份运行，而不是 root。）“无法初始化接受的套接字”正是 Graylog 无法读取这些文件出现的错误。

    您通常希望您的密钥、证书和其他文件位于/etc/graylog（我使用/etc/graylog/keys）下并归graylog用户所有。确保密钥对组或其他人不可读。

  3. 我们最终解决了这个问题，让客户端通过 TLS 将带有 rsyslog 的日志推送到收集服务器上的 rsyslog，然后让收集服务器上的 rsyslog 将这些日志转发到 graylog2。

    示意图： Dev-machine 1 -> rsyslog -> TLS -> 收集服务器：rsyslog -> graylog2
