我在CentOS7上安装了Jenkins,在尝试更新/安装插件时遇到了SSL错误.经过一番调查,结果发现我在Java CA商店中缺少根CA证书.
我使用keytool实用程序将缺少的CA证书添加到Java CA存储中并且它工作正常.但是我发现不得不篡改它很烦人.
难道没有办法让Java继承系统信任的根CA证书吗?如果有,怎么样?
解决方法:
只需将证书文件复制到CentOS 7.x上的此目录:
$sudo cp <cert file> /etc/pki/ca-trust/source/anchors/
将证书文件放入此目录后,运行此命令以使用此新添加的证书更新系统:
$sudo update-ca-trust
Java怎么样?
如果您查看update-ca-trust的手册页,您将看到以下部分:
$man update-ca-trust
…
/etc/pki/java/cacerts
Classic filename, file contains a list of CA certificates trusted
for TLS server authentication usage, in the Java keystore file
format, without distrust information. This file is a
symbolic link that refers to the consolidated output created by the
update-ca-trust command.
如果查看该文件,您可以看到它如何插入/ etc / pki目录结构的其余部分:
$ll /etc/pki/java/cacerts
lrwxrwxrwx. 1 root root 40 May 2 10:41 /etc/pki/java/cacerts -> /etc/pki/ca-trust/extracted/java/cacerts
如果我们对它运行Java keytool:
$keytool -list -keystore /etc/pki/java/cacerts -storepass changeit |& head
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 155 entries

您可以看到上面已经获得了所有可用的证书,它们会自动合并到这个Java JKS文件中.该文件可供系统上运行的任何Java应用程序使用.
