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

libevent-2.0.so.5 => not found    （没有找到该文件）

libpthread.so.0 => /lib64/libpthread.so.0 (0x00002b83fce0e000)

libc.so.6 => /lib64/libc.so.6 (0x00002b83fd029000)

librt.so.1 => /lib64/librt.so.1 (0x00002b83fd381000)

/lib64/ld-linux-x86-64.so.2 (0x00002b83fc9b0000)

> LD_DEBUG=libs ./memcached -v

#找到默认路径 /usr/lib/

>sudo ln -s /usr/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5

>sudo ldd /usr/local/bin/memcached

#提示

libevent-2.0.so.5 => /usr/lib64/libevent-2.0.so.5 (0x00002b83fcbcd000)

libpthread.so.0 => /lib64/libpthread.so.0 (0x00002b83fce0e000)

libc.so.6 => /lib64/libc.so.6 (0x00002b83fd029000)

librt.so.1 => /lib64/librt.so.1 (0x00002b83fd381000)

/lib64/ld-linux-x86-64.so.2 (0x00002b83fc9b0000)

error while loading shared libraries: libudev.so.0 的问题

在linux下运行koala的时候遇到了问题: 应该是缺少文件libudev.so.0 在/lib和/lib64目录下也都没有这个文件.然后网上找解决方案,在/lib/x86_64-linux-gnu/目录下找到一个文件:libudev.so.1 于是做了一个软连接: sudo ln -s /lib/x86_64-linux-gnu/libudev.so.1 /lib/x86_64-linux-gnu/libudev.so.0 搞定. 参考自: error while loading share
