在使用memcached的时候时间不同步造成缓存失效问题,所以需要统一时间。

但是centos系统每分钟都会有几秒钟的差量,结果很严重。

Make a backup should anything go wrong.

1
cp /grub/grub.conf /grub/grub.conf.backup

Open the file to make the required changes.

1
nano /grub/grub.conf

Add the following text to the kernel line.
If the OS is 32 Bit:

1
divider=10 clocksource=acpi_pm

Or if the OS is 64 Bit:

1
notsc divider=10

Finally save the file, and reboot the server.

1
reboot
