前两天更新了某些有用的东西，结果不知道怎么回事lnmp的php-fpm无法启动，显示错误：
Starting php-fpm /usr/local/php/sbin/php-fpm: error while loading shared libraries: libicui18n.so.48: cannot open shared object file: No such file or directory
failed
于是：
whereis libicui18n.so.48
没有结果，看样子应该是系统里真的没有libicui18n.so.48这个DD，于是乎尝试：
sudo apt-get install libicui18n
不出意料果然

最后在http://www.cnblogs.com/xiaoCon/p/3147716.html找到了包的名字，于是：
