我读过Oracle Java 8
应该支持这些协议，但是OpenJDK可能不支持这些协议吗？还是应该以某种方式启用它？

更新资料

Oracle的JCE加密提供程序安装在下jre/lib/security/，但没有帮助。

答案1

小编典典

因此，我正在运行类似的设置，其中一个AWS盒子运行openjdk-1.8.0.51。为我解决的是像这样添加bouncycastle作为提供程序：

添加bcprov-<verion>.jar到/usr/lib/jvm/jre/lib/ext
编辑/usr/lib/jvm/jre/lib/security/java.security将以下行添加到提供程序列表中：
```
security.provider.6=org.bouncycastle.jce.provider.BouncyCastleProvider
```

（我将其添加为第六项，但如果愿意，可以按顺序添加更高的项）

重新启动了我的应用程序，并能够使用基于EC的密码套件，例如TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256。

ArchLinux pacman 安装 openjdk

刚在 vm 上装了个 archlinux，然后配 java，用 pacman -S jre7-openjdk 安装，配置环境变量的时候，不知道怎么配，网上的说法都是在 /opt/jdk 下，但是我的 /opt 下面是空的，尝试在 /usr/bin 和 /usr/sbin 里面找，也没有找到～～请教高手

环境： 3.4.7-1-ARCH

安装：

[root@glide ~]# pacman -S jre7-openjdk

Eclipse OpenJ9 v0.39 发布，支持 OpenJDK 20 新特性

Eclipse OpenJ9 是一个高性能、开源的 Java 虚拟机，最初由 IBM 开发，后来交由 Eclipse 基金会维护。

近日，Eclipse OpenJ9 发布了 v0.39 版本，带来了对 OpenJDK 20 的支持，以及一些其他的改进和修复。

OpenJDK 20 是 Java 的最新版本，包含了一些新的特性，如最新的向量 API、更新的虚拟线程实现、外部函数和内存 API 等。Eclipse OpenJ9 v0.39 能够支持这些新特性，并且在性能和稳定性方面也有所提升。此外，OpenJ9 v0.39 还提高了对 RHEL8 的要求，需要至少 RHEL 8.6 版本，并且修复了一些其他的问题。

Eclipse OpenJ9 v0.39 的下载地址和更多细节可以在 GitHub 和 Eclipse.org 上找到。

linux openjdk1.8安装

记一次linux 上使用yum 安装openjdk1.8过程

使用yum查找jdk: yum search java|grep jdk
- 使用yum时遇到上图所示问题，解决办法（修改dns配置）：
```
vi /etc/resolv.conf
在文件/etc/resolv.conf最后写入：nameserver 8.8.8.8
```
- 之后再执行查找命令，结果如下图所示，
执行安装命令：yum install java-1.8.0-openjdk
如遇，输入y即可

安装成功后，默认安装路径在/usr/lib/jvm/下边，
如/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.144-0.b01.el6_9.x86_64

查看安装路径(如下图所示)：
which java
ls -lrt /usr/bin/java
...
验证java是否安装成功
- 查看java版本：java -version
- 查看java是否可用：javac
  
  错误原因：默认安装完只有运行环境，java安装目录下只有jre文件夹
安装开发环境yum install java-1.8.0-openjdk-devel.x86_64
安装完可看到java安装目录下出现bin、lib等文件夹:

再次输入javac

说明安装成功

设置环境变量
修改/etc/profile文件：vi /etc/profile
在profile文件末尾新增如下内容：

   #set java environment
   JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.144-0.b01.el6_9.x86_64
   JRE_HOME=$JAVA_HOME/jre
   CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
   PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
   export JAVA_HOME JRE_HOME CLASS_PATH PATH

如下图所示：

使环境变量生效：source /etc/profile

至此jdk安装成功

linux 上使用yum 安装openjdk1.8

使用yum查找jdk: yum search java|grep jdk

  -J<flag>                   Pass <flag> directly to the runtime system
  -Werror                    Terminate compilation if warnings occur
  @<filename>                Read options and filenames from file

设置环境变量
修改/etc/profile文件：vi /etc/profile
在profile文件末尾新增如下内容：

#set java environment
   JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64
   JRE_HOME=$JAVA_HOME/jre
   CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
   PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
   export JAVA_HOME JRE_HOME CLASS_PATH PATH

使环境变量生效：source /etc/profile

[root@preproduct1 /usr/lib/jvm]# cd /usr/lib/jvm
[root@preproduct1 /usr/lib/jvm]# cd java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64/
[root@preproduct1 /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64]# source /etc/profile
[root@preproduct1 /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64]# echo $JAVA_HOME
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64

至此jdk安装成功
