yum报错的问题

可能是因为重复安装了curl .7.45 ，导致yum报错：

/usr/lib64/python2.6/site-packages/pycurl.so: undefined symbol: CRYPTO_set_locking_callback

网上看到是动态库冲突，按网上说的如下操作：

[root@iZ94nhwre0dZ ~]#  ldd /usr/lib64/python2.6/site-packages/pycurl.so

      linux-vdso.so.1 =>  (0x00007fff677f6000)

      libcurl.so.4 => /usr/lib/libcurl.so.4 (0x00007f826a94a000)

      libpython2.6.so.1.0 => /usr/lib64/libpython2.6.so.1.0 (0x00007f826a5a4000)

      libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f826a386000)

      libc.so.6 => /lib64/libc.so.6 (0x00007f8269ff2000)

      librt.so.1 => /lib64/librt.so.1 (0x00007f8269dea000)

      libz.so.1 => /lib64/libz.so.1 (0x00007f8269bd3000)

      libdl.so.2 => /lib64/libdl.so.2 (0x00007f82699cf000)

      libutil.so.1 => /lib64/libutil.so.1 (0x00007f82697cc000)

      libm.so.6 => /lib64/libm.so.6 (0x00007f8269547000)

      /lib64/ld-linux-x86-64.so.2 (0x000000384b200000)

 

[root@iZ94nhwre0dZ ~]# find / -name "libcurl.so.4"

/usr/lib/libcurl.so.4    

/usr/lib64/libcurl.so.4

/usr/local/lib/libcurl.so.4

/usr/local/att/curl-7.45.0/lib/.libs/libcurl.so.4

[root@iZ94nhwre0dZ ~]# find / -name "libcurl.so.4"

libcurl.so.4指向四个动态库

一开始以为应该是指向是第一个动态库，就把这三个库删除了

 /usr/lib64/libcurl.so.4

/usr/local/lib/libcurl.so.4

/usr/local/att/curl-7.45.0/lib/.libs/libcurl.so.4

之后报错，找了好久才发现原来应该指向/usr/lib64/libcurl.so.4

保留/usr/lib64/libcurl.so.4

删除其余的，问题解决。
