命令运行之后出错：
error: Failed dependencies:
libcrypto.so.6()(64bit) is needed by couchbase-server-2.0.0-1976.x86_64
libssl.so.6()(64bit) is needed by couchbase-server-2.0.0-1976.x86_64
根据上面的错误提示，寻找包含 libcrypto.so.6 的安装包，运行下面的命令：
yum provides */libcrypto.so.6 [root@7-node4 ~]# yum provides */libcrypto.so.6 Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * epel: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com base/7/x86_64/filelists_db | 6.2 MB 00:15 docker-main-repo/filelists_db | 21 kB 00:00 epel/x86_64/filelists_db | 7.3 MB 00:18 extras/7/x86_64/filelists_db | 467 kB 00:00 nginx/x86_64/filelists_db | 12 kB 00:00 salt-latest/7/x86_64/filelists_db | 71 kB 00:00 updates/7/x86_64/filelists_db | 5.0 MB 00:11 openssl098e-0.9.8e-29.el7.centos.2.i686 : A compatibility version of a general : cryptography and TLS library Repo : base Matched from: Filename : /usr/lib/libcrypto.so.6 openssl098e-0.9.8e-29.el7.centos.2.x86_64 : A compatibility version of a general : cryptography and TLS library Repo : base Matched from: Filename : /usr/lib64/libcrypto.so.6
发现 openssl098e-0.9.8e-17.el6.centos.2.x86_64
安装该版本的 opensll 包：
yum install openssl098e-0.9.8e-17.el6.centos.2.x86_64 这样就解析依赖包的安装,其它也是一样的方法可以查找出来.
