执行代码：
www:~ nginx$ ln -s sphinx-3.0.3/bin/indexer /usr/local/bin/indexer
www:~ nginx$ whereis indexer
www:~ nginx$ which indexer
www:~ nginx$ indexer
-bash: /usr/local/bin/indexer: No such file or directory
www:~ nginx$ ls -la /usr/local/bin/indexer
lrwxr-xr-x 1 nginx admin 24 7 21 10:11 /usr/local/bin/indexer -> sphinx-3.0.3/bin/indexer
