请教个jdk 弱智问题

[renwfy]

centos 服务端部署, jdk是直接安装，还是把提供的那个jdk放什么路径？？

[renwfy]

[qaiu]

在安装服务之前可以将服务脚本里jdk改为实际路径，截图所示路径应该是默认路径

。。既然已经安装了，所以可以把jdk安装到截图指定路径

[renwfy]

奇怪了，还是报错呢！！！

[qaiu]

哪个版本？

[qaiu]

建议下载最新发行版，解压后，去解压目录下netdisk-fast-download.jar所在目录

先手动启动 执行命令 /root/java/jdk-17.0.2/bin/java -jar netdisk-fast-download.jar 看下有无报错 如果有报错可能是jdk问题 如果没问题再安装服务

[renwfy]

好的，我试试。我下载的应该是最新版本

[renwfy]

sdk用的这个 https://lz.qaiu.top/ec/6ebc9f2e0bbd53b4c4d5b11013f40a80NHvcYU

[renwfy]

[qaiu]

OK，我验证一下，稍等

[qaiu]

查看一下java版本 /root/java/jdk-17.0.2/bin/java --version 正常是

openjdk 17.0.8 2023-07-18
OpenJDK Runtime Environment (Alibaba Dragonwell Standard Edition)-17.0.7.0.7+7-GA (build 17.0.8+7)
OpenJDK 64-Bit Server VM (Alibaba Dragonwell Standard Edition)-17.0.7.0.7+7-GA (build 17.0.8+7, mixed mode, sharing)

如果版本没问题，看下是否是下载的0.1.8版本，我这边测试是OK的，应该和操作系统没关系

如果服务跑不起来，建议先按我上面发的命令，单独启动试试 来排除是服务脚本的问题

[qaiu]

上面的报错信息，看不出啥原因来

[renwfy]

好，我再试一下

[renwfy]

[renwfy]

难道是服务器环境问题

[qaiu]

难道是服务器环境问题

是网上找一下，试一下别的jdk17，或者直接下载个最新的jdk21 应该都兼容的，我用的是阿里的jdk17，不排除和服务器不兼容的情况

还有种可能就是看看系统里有没有配置java相关的环境变量，有的话就去除，那个安全类找不到，我怀疑是服务器自带了java8环境，而环境变量又写入了类路径，导致jdk17运行环境出了问题，如果是这种情况，可以直接在别的目录执行java -version看看有没有预装java

[renwfy]

我换了一个服务器同样的操作可以正常工作，我再找找原因吧。麻烦了

[renwfy]

跑起来后，缓存之类的配置，是需要单独处理的吗？我看每次刷新结果不一样，好像缓存没生效呢？

[qaiu]

默认配置好了，调用json接口复制过来我看一下

[renwfy]

这里 http://xxx:6400/json/parser?url=

每次请求结果都是变的

[qaiu]

这里 http://154.83.12.153:6400/json/parser?url=

每次请求结果都是变的 http://154.83.12.153:6400/json/parser?url=https://share.feijipan.com/s/GOCGlUWe

你下的是0.1.7版本，0.1.8有缓存有效期字段

[renwfy]

好的，我重新部署下

[renwfy]

0.1.8 可以了
