After trying to get async-profiler working stand-alone, I discovered there are some Linux kernel parameters that need to be set to allow non-root profiling. Setting these allowed gradle-profiler to work. I found this quite confusing, and had tried gradle-profiler on two different computers over...
Linux Boot kernel参数 Kernel Boot Parameters The following table lists commonly-used kernel boot parameters. The kernel boot parameters that were last used to boot a system are recorded in/proc/cmdline, for example: #cat /proc/cmdlinero root=/dev/mapper/VolGroup-lv_root rd_NO_LUKS KEYBOARDTYP...

Linux(像之前的Unix)在安全方面口碑很好,这是因为Kernel跟踪记录了每个运行进程的user ID和group ID,每次当一个应用企图访问资源(比如打开一个文件来写入)的时候,Kernel就会核对文件上的访问许可然后做出允许/禁止的命令。这种访问控制模式最终对整个Linux系统的安全作用很大。
For root installations, the database manager uses a formula to automatically adjust kernel parameter settings and eliminate the need for manual updates to these settings.
