error while loading shared libraries的解決方法

在/etc/ld.so.conf中加入/usr/local/lib这一行，保存之后，再运行：/sbin/ldconfig –v

这就相当于在Windows中添加个环境变量一样

如果启动找不到 
error while loading shared libraries: libfdfsclient.so: cannot open shared object file: No such file or directory 
error while loading shared libraries: libfastcommon.so: cannot open shared object file: No such file or directory 
请使用以下软连接 
ln -s /usr/local/fdfs/lib/libfastcommon.so /usr/lib/libfastcommon.so 
ln -s /usr/local/fdfs/lib/libfastcommon.so /usr/lib64/libfastcommon.so 
ln -s /usr/local/fdfs/lib/libfdfsclient.so /usr/lib64/libfdfsclient.so 
ln -s /usr/local/fdfs/lib/libfdfsclient.so /usr/lib/libfdfsclient.so
