memcached: error while loading shared libraries: libevent-2.0.so.5: cannot o解决
1.检查memcached是否正常运行
#ps aux | grep memcached #或者 #telnet localhost 11211
会显示memcached的基本信息
如果启动时出现“memcached: error while loading shared libraries:libevent-2.0.so.5: cannot open shared object file: No such file or directory”之类的信息,表示memcached 找不到 libevent 的位置
2、查看libevent 在哪里
# whereis libevent #提示 libevent-2.0.so.5: /usr/local/lib/libevent-2.0.so.5
3、再看memcached 从哪里找它
> ldd /usr/local/bin/memcached (ldd指令不熟悉的去查看下)
#提示
