如何获取默认java安装的cacerts的位置? [英] How to obtain the location of cacerts of the default java installation?

问题描述

当您未定义JAVA_HOME或JRE_HOME时，我正在研究如何获取默认java安装的cacerts位置.

我需要至少适用于OS X和Linux的解决方案.

是的. java -v被认为可以工作:)

解决方案

在 Linux 下，查找$JAVA_HOME的位置:

readlink -f /usr/bin/java | sed "s:bin/java::"

cacerts在lib/security/cacerts下:

$(readlink -f /usr/bin/java | sed "s:bin/java::")lib/security/cacerts

在 mac OS X 下，找到$JAVA_HOME运行:

/usr/libexec/java_home

cacerts在Home/lib/security/cacerts下:

$(/usr/libexec/java_home)/lib/security/cacerts

更新(带有JDK的OS X)

上面的代码已在未安装JDK的计算机上进行了测试. 安装了JDK后，如pR0P所述，它位于

$(/usr/libexec/java_home)/jre/lib/security/cacerts

I am looking on how how to obtain the location of cacerts of the default java installation, when you do not have JAVA_HOME or JRE_HOME defined.

I need a solution that works at least for OS X and Linux.

Yes. java -v is assumed to work :)

解决方案

Under Linux, to find the the location of $JAVA_HOME:

readlink -f /usr/bin/java | sed "s:bin/java::"

the cacerts are under lib/security/cacerts:

$(readlink -f /usr/bin/java | sed "s:bin/java::")lib/security/cacerts

Under mac OS X , to find $JAVA_HOME run:

/usr/libexec/java_home

the cacerts are under Home/lib/security/cacerts:

$(/usr/libexec/java_home)/lib/security/cacerts

UPDATE (OS X with JDK)

above code was tested on computer without JDK installed. With JDK installed, as pR0Ps said, it's at

$(/usr/libexec/java_home)/jre/lib/security/cacerts
