Recently, Nagios has been studied.
Oldboy said the software has strict requirements on "Time Synchronization. However, I chose to act as a virtual machine on the Nagios server when I learned rhce. At that time, I found that time synchronization is always incorrect. To this end, we have also tried to install "VMware Tools ". Although the installation is successful, the time synchronization is still inaccurate (the error may be more than six hours ).
This time, we can change the number of virtual machines. However, I really don't want to wait any longer. What do you do ...... Fortunately, it didn't take much time to solve this problem.
Search for the keyword "15 Aug 00:33:03 ntpdate [15395]: adjust time server 202.112.31.197 offset-0.180265 sec" on Baidu and read two articles. Although I did not understand it, I realized that the problem may occur when I select "Time Zone" when installing centos. However, I felt that I should not be so careless at the time. Can I still choose the "Time Zone?
Fortunately, centos on this virtual machine was installed in "full multi-user mode. Then, I chose the "init 5" command to try again.
Go to the centos desktop, find "time" in the upper right corner, right-click "time", and select the "Adjust Date & time" menu item in the pop-up menu.

In the displayed Properties dialog box, select the "Time Zone" tab and find that the current time zone was actually set in the western United States (not sure what the specific place name is ). I move the mouse, find the location of East Asia, and then click the arrow to find "Shanghai ". After positioning, you can click "OK" to exit.

Now let's look at the time. It's already the current time.
The problem is not difficult to solve, but it has plagued me for more than three years.
