为什么无法远程访问 glassfish 管理控制台？

Question

我有一个虚拟机 Centos7 虚拟机。我从这里安装了 glassfish 5.0：Full platform - glassfish 5.0。我只是将文件夹解压缩到 /opt 中。我正在使用“仅限主机”。

以下是我的java版本：

java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

我已使用以下命令启用安全管理员：

asadmin --host localhost --port 4848 enable-secure-admin

我进入 vm shell 并输入“ifconfig”来了解 IP。 然后，我进入 Windows 主机的 power shell (win + x) 并键入，通过 ssh 连接：

ssh user@x.x.x.x

然后：

cd /opt/glassfish5/bin
./asadmin start-domain domain1

然后我回到我的主机，我打开谷歌浏览器并：

1. http://x.x.x.x:8080 看起来不错
2. http://x.x.x.x:4848 强制使用 https，然后浏览器告诉我无法访问该网站

我曾尝试卸载 secure-admin（至少在 glassfish 给我异常说 DAS 或类似的东西需要 secure-admin 之前）：

./asadmin --host localhost --port 4848 disable-secure-admin

但我得到以下异常：

NCLS-ADMIN-00010
javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
Command disable-secure-admin failed.

调用管理控制台后，我的日志中出现以下异常：

Answer 1

答案是您的 Java 版本对于 GlassFish 来说太新。我已经在这里回答了这个问题：https://stackoverflow.com/a/49998266/212224

要停止java.lang.NoClassDefFoundError，您需要使用不高于8u151

的Java版本

这是由于 Grizzly 使用的内部 JDK 类发生了变化 HTTP/2。

GlassFish 5.0 没有有最新版本的 Grizzly 与最新的 Java 8 更新兼容。如果您使用的是 GlassFish 5.0 看到这些错误，你有两个选择：

1. 将 Java 降级到 8u152 或更早版本
2. Download the latest GlassFish 5.0.1 nightly，应该修复这个问题
