MySQL Error 4076: Missing Regex Locale Data
Description
This error indicates that the MySQL server's regular expression library cannot find or access the necessary locale-specific resources. It typically occurs when a regular expression function that relies on locale-dependent character classification or collation rules is used, and the required locale data is either missing, corrupted, or improperly configured on the server's operating system.
Error Message
Missing locale resource in regular expression library.
Known Causes
3 known causesOS Locale Data Missing/Corrupted
The underlying operating system's locale resource files, which MySQL's regular expression library depends on for character sets and collation, are either not installed or have become corrupted.
Misconfigured Server Locale
MySQL's `lc_messages` system variable or other locale-related settings are configured to use a locale that is not properly installed or recognized by the host operating system.
Incorrect Environment Locale Variables
The operating system's environment variables (e.g., LANG, LC_ALL, LC_CTYPE) for the MySQL server process do not correctly specify a valid locale, preventing the regex library from initializing properly.
