Win10下 80端口被system(pid=4)占用的解决方法

阅读更多关于 Win10下 80端口被system(pid=4)占用的解决方法

经过查询，发现占用80端口的确是 SQL Server 2012 里面的组件——SQL Server Reporting Services (SQLSERVER2012)。是 SQL Server 的日志系统，就是他好端端的突然占用了80端口，而且对于普通人来讲，这个组件的作用没啥用，关掉也是节约资源。关闭方法很简单，在运行框中输入 services.msc ，进入服务窗口。或者直接在开始菜单里面的搜索框中输入“服务”即可打开。然后找到 SQL Server Reporting Services (SQLSERVER2012) 这个服务，然后停止，被占用的80端口就被释放出来了。你也可以设置它的启动方式为“禁用”。来源： https://www.cnblogs.com/linyijia/p/12190499.html

How to get the PID from a ProcessSerialNum in OSX 10.9?

阅读更多关于 How to get the PID from a ProcessSerialNum in OSX 10.9?

问题 GetProcessPID was marked deprecated in OSX 10.9 along with the note: Use the processIdentifier property of the appropriate NSRunningApplication object. The problem is the constructing class methods for NSRunningApplication do not have a way to get a NSRunningApplication by a ProcessSerialNum , only by PID or bundle name. Bundle name is too ambiguous (there could be multiple instances) and I don't have the PID (it's what I want). In OSX 10.9, is there a way to get the PID when you have a PSN?

Must a process group have a running leader process?

阅读更多关于 Must a process group have a running leader process?

问题 In Unix-like operating systems, if a process' pid and its pgid are equal, then the process is a process group leader. However, if the process leader has exited and the other processes in the same group are still running, who is the succeeding leader process? 回答1: There is no succeeding leader: once a process group leader exits, the group loses leadership. Nothing requires a process group to have a leader, it's perfectly fine not to have one, and you can still send signals to every element in
