无法在centOs中降级openssl LIB

我试图使用“sudo-yum-install-nginx”安装nginx，导致以下错误：

Error: Package: 1:openssl-1.0.1e-42.el7_1.9.x86_64 (client)
           Requires: openssl-libs(x86-64) = 1:1.0.1e-42.el7_1.9
           Installed: 1:openssl-libs-1.0.2k-19.el7.x86_64 (installed)

           Available: 1:openssl-libs-1.0.2k-12.el7.i686 (localrepo)
              ~openssl-libs(x86-32) = 1:1.0.2k-12.el7

Error: Package: erlang-crypto-20.3-1.el7.centos.x86_64 (@localrepoMoney)
           Requires: libcrypto.so.10(OPENSSL_1.0.2)(64bit)
           Removing: 1:openssl-libs-1.0.2k-19.el7.x86_64 (installed)

              ~libcrypto.so.10(OPENSSL_1.0.1)(64bit)

为了解决这个问题，我遵循了以下一系列命令：

=> yum list openssl-libs --show-duplicates

输出：

Installed Packages
openssl-libs.x86_64                                                            1:1.0.2k-19.el7                                                                 installed

openssl-libs.x86_64                                                            1:1.0.1e-42.el7_1.9                                                             client
openssl-libs.i686                                                              1:1.0.2k-12.el7                                                                 localrepo

然后，我尝试降级“openssl”，随后出现以下错误：

Error: Package: 1:openssl-1.0.1e-42.el7_1.9.x86_64 (client)
           Requires: openssl-libs(x86-64) = 1:1.0.1e-42.el7_1.9

              ~openssl-libs(x86-32) = 1:1.0.2k-12.el7

              ~libcrypto.so.10(OPENSSL_1.0.1)(64bit)

当我尝试下载lybcrypto.so.10时，出现以下错误

Error:  Multilib version problems found. This often means that the root
       cause is something else and multilib version checking is just
       pointing out that there is a problem. Eg.:

         1. You have an upgrade for openssl-libs which is missing some
            dependency that another package requires. Yum is trying to
            solve this by installing an older version of openssl-libs of the
            different architecture. If you exclude the bad architecture
            yum will tell you what the root cause is (which package
            requires what). You can try redoing the upgrade with
            --exclude openssl-libs.otherarch ... this should give you an error
            message showing the root cause of the problem.

         2. You have multiple architectures of openssl-libs installed, but
            yum can only see an upgrade for one of those architectures.
            If you don't want/need both architectures anymore then you
            can remove the one with the missing update and everything
            will work.

         3. You have duplicate versions of openssl-libs installed already.
            You can use "yum check" to get yum show these errors.

       ...you can also use --setopt=protected_multilib=false to remove
       this checking, however this is almost never the correct thing to
       do as something else is very likely to go wrong (often causing
       much more problems).

       Protected multilib versions: 1:openssl-libs-1.0.2k-12.el7.i686 != 1:openssl-libs-1.0.2k-19.el7.x86_64

请告诉我如何解决这个问题。我已经在这上面呆了很长时间了。

谢谢

看来Erlang不是从官方CentOS repo安装的，它使用的OpenSSL版本比当前CentOS版本的官方支持版本更新。您可以尝试从EPEL repo重新安装Erlang或完全卸载它，安装支持openssl 1.0.2k的Nginx（例如从EPEL安装或自行构建），或升级CentOS。
