Linux服务器时区调整

Linux服务器时区调整

起因:前端项目时间显示少8个小时,查询服务器时间,是UTC标准时间,要调整成UTC+8即CST中国时区

1.查询当前时间:

# date 
2017年 11月 09日 星期四 12:19:23 CST
[root@localhost Asia]# date -R
Thu, 09 Nov 2017 12:19:32 +0800

2.首先使用tzselect进行时间调整(失败,由于服务器依赖的时区文件有问题):

[root@localhost ~]# tzselect
Please identify a location so that time zone rules can be set correctly.
Please select a continent or ocean.
 1) Africa
 2) Americas
 3) Antarctica
 4) Arctic Ocean
 5) Asia
 6) Atlantic Ocean
 7) Australia
 8) Europe
 9) Indian Ocean
10) Pacific Ocean
11) none - I want to specify the time zone using the Posix TZ format.
#? 5
Please select a country.
 1) Afghanistan       18) Israel            35) Palestine
 2) Armenia       19) Japan         36) Philippines
 3) Azerbaijan        20) Jordan            37) Qatar
 4) Bahrain       21) Kazakhstan        38) Russia
 5) Bangladesh        22) Korea (North)     39) Saudi Arabia
 6) Bhutan        23) Korea (South)     40) Singapore
 7) Brunei        24) Kuwait            41) Sri Lanka
 8) Cambodia          25) Kyrgyzstan        42) Syria
 9) China         26) Laos          43) Taiwan
10) Cyprus        27) Lebanon           44) Tajikistan
11) East Timor        28) Macau         45) Thailand
12) Georgia       29) Malaysia          46) Turkmenistan
13) Hong Kong         30) Mongolia          47) United Arab Emirates
14) India         31) Myanmar (Burma)       48) Uzbekistan
15) Indonesia         32) Nepal         49) Vietnam
16) Iran          33) Oman          50) Yemen
17) Iraq          34) Pakistan
#? 9
Please select one of the following time zone regions.
1) Beijing Time
2) Xinjiang Time
#? 1

The following information has been given:

    China
    Beijing Time

Therefore TZ='Asia/Shanghai' will be used.
Local time is now:  Thu Nov  9 03:50:41 UTC 2017.
Universal Time is now:  Thu Nov  9 03:50:41 UTC 2017.
Is the above information OK?
1) Yes
2) No
#? 1

You can make this change permanent for yourself by appending the line
    TZ='Asia/Shanghai'; 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:
Asia/Shanghai

3.查看有问题的时区文件(下面是正确的,本身有2个服务器,2个不一样所以断定时间不对那个有问题):

# cat /usr/share/zoneinfo/Asia/Shanghai
TZif?\???'p?????Z??6ip ~h?!Iap"^J?#)Cp$Gg%_?&'I&?A?(+(?#?~?p?CDTCSTTZif2
                                                                        ????~6C)?????\???????'p?????????????Z??6ip ~h?!Iap"^J?#)Cp$Gg%_?&'I&?A?(+(?#?q?~?pLMTCDTCST
CST-8

4.从一个服务器拷贝时区文件到另外一个服务器(10.4—>10.6):

1.将10.4服务器上的时区文件拷贝到本地

$ scp [email protected]:/usr/share/zoneinfo/Asia/Shanghai /Users/hs/Desktop/Shanghai

2.将本地时区文件拷贝到10.6服务器,覆盖对于时区文件

$ scp /Users/hs/Desktop/Shanghai [email protected]:/usr/share/zoneinfo/Asia/Shanghai

5.查看时间正确,不正确的话此时再次镜像时区选择即可

[root@localhost ~]# tzselect
