我已经使用自签名证书运行 Jenkins 实例一段时间了，除了必须在浏览器中创建证书验证异常的麻烦之外，它运行良好。所以今天我从StartSSL获得了一个免费的 tier 1 证书，更改了路径/etc/sysconfig/jenkins，并重新启动了服务，但它根本不起作用：
$ openssl s_client -connect localhost:8080 -debug

openssl似乎认为我的证书是合法的：

将其放入 Java KeyStore 文件后，它似乎仍然有效（匿名 FQDN）：
$ keytool -list -keystore jenkins.jks
Enter keystore password:
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 1 entry
jenkins_domain_tld, Jan 25, 2014, trustedCertEntry,
Certificate fingerprint (MD5): 3D:6A:AB:83:0B:E8:21:DF:C3:17:E9:88:AD:19:24:EE
旧的自签名证书密钥存储区没有太大区别：
$ keytool -list -keystore jenkins.jks.old
Enter keystore password:
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 1 entry
jenkins_domain_tld, Jan 11, 2014, PrivateKeyEntry,

我尝试直接使用证书JENKINS_ARGS="--httpsCertificate=/var/lib/jenkins/jenkins.crt.pem --httpsPrivateKey=/var/lib/jenkins/jenkins.key.pem"，但詹金斯根本不会启动：

安装中间证书后：

爪哇版：
java version "1.7.0_51"
OpenJDK Runtime Environment (IcedTea 2.4.4) (ArchLinux build 7.u51_2.4.4-1-x86_64)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)
这似乎并没有改变什么。
据我所知，设置JENKINS_DEBUG_LEVEL="99"没有产生任何相关的日志行。
我相信旧的CSR是使用2048 位生成的，而新的 CSR 是使用4096生成的——这可能是原因吗？
两个公钥都是 2048 位 RSA。
根据diff -u <(openssl x509 -in jenkins.crt.pem.old -text) <(openssl x509 -in jenkins.crt.pem -text)旧证书使用sha256WithRSAEncryption，而新证书使用sha1WithRSAEncryption签名算法。
别名很重要吗？Jenkins 不支持超过 2048 位的密钥吗？Jenkins/OpenJDK/ Amazon Linux是否不适用于某些键？
我还应该检查什么？
