error while loading shared libraries: libevent-2.0.so.5处理

启动memcache的时候，报如下错误：
#/usr/local/bin/memcached -d -m 100 -p 11211 -u nobody -c 65535
/usr/local/bin/memcached: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory

查看是否已安装libevent
#locate libevent-2.0.so.5

64位的系统，在相应的路径上查找不到文件，需要做个软链

ldd /usr/local/bin/memcached
