Last time I talked about how to adjust the Linux system time. In the project, we often need to view system logs when analyzing system problems. In this case, if a cluster or ha application is used, the time is very important for locating the sequence and cause of the problem. Therefore, we hope to have a way to ensure that the
The cat used to write ASM and C often do not forget the "reverse", and then write the drive when the VM and the like to build a "two-machine" debugging Environment for debugging, but also for some small software crack cd-key the joy of God Horse. Since the use of the bird so-called advanced Dynamic language Ruby, this black inverse mentality seems to gradually weaken ... But it's hard to get the chance to catch the itch.Ruby+linux's open source way has not been to the bin code as well as dis asm

In a clustered environment and multi-server applications that require log synchronization, in order to ensure normal collaboration between multiple servers, it is necessary to keep their time consistent, and manually adjust the time on multiple servers is extremely unscientific, and this requires the use of NTP
The recent Exsi server time is always wrong, in the time configuration is always not correct display, using the following methods, you can quickly update to the latest time.System: Exsi 5.5

Two ways to synchronize NTP: 1. Synchronize directly with the Ntpdate command 2. Smooth sync with NTPD serviceThe defect of the direct synchronization method: It will cause the scheduled task to be done again.The offset of the synchronization time of the smooth synchronization is not too steep, according to the offset, the mean variance equivalent of each synchro
