在 centos 6 上創建新的語言環境

昨晚出現電源故障，系統關閉。

早上系統啟動時，PostgreSQL db server 無法啟動。

查看 pgstartup.log 文件時，發現以下行。

< 2017-01-23 15:26:17.577 IST >DETAIL:  The database was initialized with LC_COLLATE "en_US.UTF-8",  which is not recognized by setlocale().
< 2017-01-23 15:26:17.577 IST >HINT:  Recreate the database with another locale or install the missing locale.

很明顯，PostgreSQL 所需的語言環境（en_US.UTF-8）在系統中不可用。

我還通過執行 locale 命令進行了交叉驗證，這是輸出。

$ locale
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.utf8
LC_CTYPE="en_US.utf8"
LC_NUMERIC="en_US.utf8"
LC_TIME="en_US.utf8"
LC_COLLATE="en_US.utf8"
LC_MONETARY="en_US.utf8"
LC_MESSAGES="en_US.utf8"
LC_PAPER="en_US.utf8"
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT="en_US.utf8"
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=

在網際網路上搜尋時，我發現我可以使用以下命令創建缺少的語言環境。

localedef -v -c -i en_US -f UTF-8 en_US.UTF-8

但是，當我執行該命令時，它會失敗並出現以下錯誤：

$ sudo localedef -v -c -i en_US -f UTF-8 en_US.UTF-8

到目前為止，我還沒有找到任何解決此錯誤的方法。

環境細節：

$ uname -r
2.6.32-573.18.1.el6.x86_64

所有 en_US 語言環境：

$ locale -a | grep en_US
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_COLLATE to default locale: No such file or directory
en_US
en_US.iso88591
en_US.iso885915
en_US.utf8

我發現了我在以下命令中所做的錯誤：

---

錯誤的命令：

localedef -v -c -i en_US -f UTF-8 en_US.UTF-8

---

正確的命令：

localedef -v -c -i en_US -f utf8 en_US.UTF-8
