memached启动报错

wuli

报错如下：

[iyunv@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

解决：

首先查看，libevent 在哪里

[iyunv@stage memcached-1.4.15]# whereis libevent

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

然后，再看memcached 从哪里找它

[iyunv@stage memcached-1.4.15]# LD_DEBUG=libs memcached -v 2>&1 > /dev/null | less

5493: find library=libhugetlbfs.so [0]; searching

5493: search cache=/etc/ld.so.cache

5493: trying file=/usr/lib64/libhugetlbfs.so

5493:

5493: find library=libevent-2.0.so.5 [0]; searching

5493: search cache=/etc/ld.so.cache

5493: search path=/lib64/tls/x86_64:/lib64/tls:/lib64/x86_64:/lib64:/usr/lib64/tls/x86_64:/usr/lib64/tls:/usr/lib64/x86_64:/usr/lib64

(system search path)

5493: trying file=/lib64/tls/x86_64/libevent-2.0.so.5

5493: trying file=/lib64/tls/libevent-2.0.so.5

5493: trying file=/lib64/x86_64/libevent-2.0.so.5

5493: trying file=/lib64/libevent-2.0.so.5

5493: trying file=/usr/lib64/tls/x86_64/libevent-2.0.so.5

5493: trying file=/usr/lib64/tls/libevent-2.0.so.5

5493: trying file=/usr/lib64/x86_64/libevent-2.0.so.5

5493: trying file=/usr/lib64/libevent-2.0.so.5

5493:

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

可以看到：是/usr/lib64/libevent-2.0.so.5，所以，创建软链

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

本机启动：

/usr/local/bin/memcached -d -m 512 -c 512 -p 12000 -u root

关闭memcached :pkill memcached
