add to /etc/ld.so.conf system file

Destiny-Hot

add /usr/local/Aria/lib
to your LD_LIBRARY_PATH environment variable, or to the /etc/ld.so.conf system file,

这几话 怎么 添加阿？
/etc/ld。so。conf  文件内容是：include ld.so.conf.d/*.conf

我应该怎么添加？  是export PATH=$PATH:/usr/local/Aria/lib
还是  也用 include阿？

echo '/usr/local/Aria/lib' > /etc/ld.so.conf.d/Aria.conf
ldconfig
