Memached startup Error

The following error is reported:

[Root @ stage memcached-1.4.15] #/usr/local/bin/memcached-d-m 512-c 512-p 12000-u root-l 211.157.137.245

/Usr/local/bin/memcached: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory

Solution:

First, check where the libevent is located.

[Root @ stage memcached-1.4.15] # whereis libevent

Libevent:/usr/lib/libevent. a/usr/lib/libevent. so/usr/lib/libevent. la

Then, let's see where memcached looks for it.

Memcached: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory

We can see that: yes/usr/lib64/libevent-2.0.so.5, so, create soft chain

[Root @ stage memcached-1.4.15] # ln-s/usr/lib/libevent-2.0.so.5/usr/lib64/libevent-2.0.so.5
