本文主要介绍当服务器无法连接互联网情况下,无法安装arthas的解决方法。
一、下载
参考文末参考文章3中下载。也可以直接把下面文中的链接取出,直接用下载器下载。
# github下载
wget https://alibaba.github.io/arthas/arthas-boot.jar
# 或者 Gitee 下载
wget https://arthas.gitee.io/arthas-boot.jar
# 打印帮助信息
java -jar arthas-boot.jar -h
二、安装
# 运行方式1,先运行,在选择 Java 进程 PID
java -jar arthas-boot.jar
当联网安装时,可以正常安装。看下面的执行日志,可以看到,联网时会到maven.aliyun.com的私服库里去获取jar包。但是离线时,是无法直接获取的,执行时,会出现无法连接aliyun.com等error。

三、离线安装
其实方法很简单,只是有时候不容易想的到。
步骤1:先在可联网的电脑上,执行java -jar arthas-boot.jar
,从执行记录中可以看到,下载下来的依赖包放在了
[INFO] arthas home: /Users/herman/.arthas/lib/3.1.7/arthas
步骤2:进入到/Users/herman/.arthas/lib/3.1.7/arthas
路径下,把所有的内容打包即可,与arthas-boot.jar
一起上传到离线的服务器。

BUG:arthas herman$ pwd

打包命令:tar -cvf
或者 zip
,用文件浏览器都行
步骤3:把打包的文件放在服务器上的用户根目录下,比如herman
用户,放在/home/herman/.arthas
下就可以。当然也可以指定执行路径。
