The following are potential configuration items that you may want to fix:
1 : debmirror package is not installed, it will be required to manage debian deployments and repositories
2 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
以上两个是关于debian系统的错误，请忽略

自我介绍一下，小编13年上海交大毕业，曾经在小公司待过，也去过华为、OPPO等大厂，18年进入阿里一直到现在。
深知大多数Java工程师，想要提升技能，往往是自己摸索成长或者是报班学习，但对于培训机构动则几千的学费，着实压力不小。自己不成体系的自学效果低效又漫长，而且极易碰到天花板技术停滞不前！
因此收集整理了一份《2024年Java开发全套学习资料》，初衷也很简单，就是希望能够帮助到想自学提升又不知道该从何学起的朋友，同时减轻大家的负担。
既有适合小白学习的零基础资料，也有适合3年以上经验的小伙伴深入学习提升的进阶课程，基本涵盖了95%以上Java开发知识点，真正体系化！
由于文件比较大，这里只是将部分目录截图出来，每个节点里面都包含大厂面经、学习笔记、源码讲义、实战项目、讲解视频，并且会持续更新！
如果你觉得这些内容对你有帮助，可以扫码获取！！（备注Java获取）
最后
Java架构学习技术内容包含有：Spring，Dubbo，MyBatis, RPC, 源码分析，高并发、高性能、分布式,性能优化，微服务 高级架构开发等等。
还有Java核心知识点+全套架构师学习资料和视频+一线大厂面试宝典+面试简历模板可以领取+阿里美团网易腾讯小米爱奇艺快手哔哩哔哩面试题+Spring源码合集+Java架构实战电子书+2021年最新大厂面试题。
