一,需求分析说明
由于项目游戏发行海外版本,游戏里的活动需要按海外时间进行,而海外阿里云主机默认是以东8区北京时间计时,故需要更改时区和时间!
二,修改linux系统时区
1,修改默认时区
#ln -sf /usr/share/zoneinfo/Europe/London /etc/timezone
2,选择时区
#tzselect
运行命令会出现交互提示,以欧洲伦敦为例
[root@ALISG]# tzselect

You can make this change permanent for yourself by appending the line
TZ='Europe/London'; export TZ
to the file '.profile' in your home directory; then log out and log in again.
Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
Europe/London
选择时区然后 添加到配置文件最后:
#vim /etc/profile
TZ='Europe/London';export TZ
#cat /etc/sysconfig/clock
ZONE="UTC"
退出再登录查看时间
#date
2017年 07月 28日 星期四 08:07:30 BST
3,写入硬件时钟
#sudo hwclock -w
