刚才突然发现网站打开很慢，一直在转，不知道哪里出了问题，赶紧登录服务器，发现服务器上执行命令也要好一会才出结果，top一下，发现CPU飙到300%多，而且一直维持在这么高，执行的命令是kthreaddk。 百度了一下，呃，挖矿病毒，不过都是kthreaddi，这个是kthreaddk，难道是升级版？ 继续百度一下处理方案， 好像也没有特别简明和确切的。 都是查看一下，删除文件以及kill进程： ls -l /proc/[pid]/exe — 这里pid就是top命令最左侧列的数值，即进程ID（process identifier ） sudo kill -9 [pid] 使用ls命令查看的时候，也都是后面有(deleted)标识，并且相关目录也是为空。 kill后随机又出现一个新的同样是执行kthreaddk命令的进程，CPU又是飙升不降。 crontab -l 命令或者 crontab -e 命令似乎没有什么信息。 后来一通搜索后懵懵懂懂的就认为是gitlab的问题，有了方向就好办了，由于gitlab是使用docker来运行的，直接 docker stop gitlab， 停止后居然CPU就恢复正常了，意外之喜。那么后面怎么办？要不要删掉实例重新创建？ 由于打算研究一下，于是重启实例，居然没事了。好吧，有惊无险糊里糊涂的处理了病毒问题，也不知道会不会再出现，只能有碰到再继续研究了。 另外，登录gitlab后，在右侧问号图标处下拉菜单选择help可以查看当前gitlab版本。

volatile Fields The Java programming language allows threads to access shared variables (§17.1). As a rule, to ensure that shared variables are consistently and reliably updated, a thread should ensure that it has exclusive use of such variables by obtaining a lock that, conventionally, enforces mutual exclusion for those shared variables. The Java programming language provides […]
