CentOS中libevent-2.0.so.5 not found 解決 ldd 方法

CentOS中libevent-2.0.so.5 not found 解決 ldd 方法

安裝memcache時，需要建立檔案索引或者說檔案串連（link），類似windows下的捷徑

啟動服務時出現 error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory

>whereis libevent-2.0.so.5

libevent-2.0.so.5: /usr/local/lib/libevent-2.0.so.5

> ldd /usr/local/bin/memcached （ldd指令不熟悉的去查看下）
libevent-2.0.so.5 => not found （沒有找到該檔案）
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
找到預設路徑 /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
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)

現在好啦，：）
