CentOS6.5 Character Set Optimization

These two days just good to do PHP-FPM memory optimization, in the view of PHP-FPM memory usage found locale-archive memory 96 M, the file is language, environment, font-related index files, because many languages are useless, deleting them to squeeze the memory. Any setlocale program will map the locale-archive file to the memory.
