Adjust and change the ubuntu time zone, time, locale, and time (1) execute tzselect to select the time zone echo & quot; TZ & amp; #39; Asia/Harbin & amp; #39; exportTZ & quot; & gt ;~ /. Profile (2) sudocp/usr/share/zoneinfo/Asia/change ubuntu time zone, time, locale change time zone, time (1) execute tzselect and select the time zone echo "TZ = 'Asia/Harbin'; export TZ" >> ~ /. Profile (2) sudo cp/usr/share/zoneinfo/Asia/ShangHai/etc/localtime run sudo ntpdate is a public NTP server located in China, used to synchronize your time setting date sudo date-s 20130413 change locale modify/var/lib/locales/supported. d/local for example: en_US.UTF-8 UTF-8 zh_CN.UTF-8 UTF-8 zh_CN.GBK GBK zh_CN GB2312 and then run locale-gen on it. Or how does sudo dpkg-reconfigure locales set locale? Setting locale is to set the locale classification attributes of 12 categories, that is, 12 LC _*. In addition to setting these 12 variables, there are two variables for convenience: LC_ALL and LANG. There is a relationship between them with a priority: LC_ALL> LC _ *> LANG. LC_ALL is set at the upper level or forcibly, while LANG is the default value. 1. if you set LC_ALL = zh_CN.UTF-8, then no matter what the LC _ * and LANG are set to, they will be forced to obey the LC_ALL settings, become a zh_CN.UTF-8. 2. if you set LANG = zh_CN.UTF-8, and other LC _ * = en_US.UTF-8, and no LC_ALL is set, then the locale of the system is set to LC _ * = en_US.UTF-8. 3. if you set LANG = zh_CN.UTF-8, and other LC _ *, and LC_ALL are not set, the system will set LC _ * to the default value, that is, the LANG value zh_CN.UTF-8. 4. if you set LANG = zh_CN.UTF-8, and other LC_CTYPE = en_US.UTF-8, other LC _ *, and LC_ALL are not set, then the locale setting of the system will be: LC_CTYPE = en_US.UTF-8, the other LC_COLLATE, LC_MESSAGES and so on will use the default value, that is, the LANG value, that is, LC_COLLATE = LC_MESSAGES = ...... = LC_PAPER = LANG = zh_CN.UTF-8. Therefore, locale is set as follows: 1. if you need a Chinese-only system, you can set LC_ALL = zh_CN.XXXX or LANG = zh_CN.XXXX. of course, you can set both, but as mentioned above, the value of LC_ALL will overwrite all other locale settings, so do not useless work. 2. if you only want to enter a Chinese environment and keep the menu, title, and system information as the English interface, you only need to set LC_CTYPE = zh_CN.XXXX, LANG = en_US.XXXX. In this way, LC_CTYPE = zh_CN.XXXX, while LC_COLLATE = LC_MESSAGES = ...... = LC_PAPER = LANG = en_US.XXXX.
