解决1:
出现以上安装错误列表的原因是：系统已经安装了其他版本的mysql-libs包和mysql数据库文件导致不兼容。
[root@localhost install-files]# yum remove mysql-libs
执行之后，还要详细检查卸载MySQL安装的所有文件，否则在后续安装发生各种错误:CentOS下MySQL的彻底卸载
问题2：
[root@Tony_ts_tian developer]# rpm -ivh MySQL-server-5.5.46-1.el6.x86_64.rpm
warning: MySQL-server-5.5.46-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
Preparing...                ########################################### [100%]
   1:MySQL-server           ########################################### [100%]
解决2：
从 rpm版本 4.1 开始，在安装或升级软件包时会检查软件包的签名。如果签名校验失败，你就会看到类似以上的错误消息：
注：新的、只针对文件头的签名：错误消息：error: Header V3 DSA signature: BAD, key ID 0352860f
注：没有安装合适的钥匙来校验签名，消息中就会包含 NOKEY：错误消息：warning: V3 DSA signature: NOKEY, key ID 0352860f
由于yum安装了旧版本的GPG keys造成的，解决办法就是（设置后无效）：
rpm --import /etc/pki/rpm-gpg/RPM*
此签名是检验安装包的有效性和安装性的。我直接跳过（安装时不校验，加--nosignature参数）检验安装:
[root@localhost install-files]# rpm -ivh MySQL-server-5.6.27-1.el6.x86_64.rpm --nosignature
问题3：
mysqld: unrecognized service
  1.  
    [root@Tony_ts_tian init.d]# service mysqld start
  2.  
    mysqld: unrecognized service
解决3：
启动脚本文件mysql的目录
  1.  
    [root@localhost install-files]# cd /etc/rc.d/init.d/
  2.  
    [root@localhost init.d]# ls
  3.  
    functions mysql netconsole network README
并没有mysqld：
[root@Tony_ts_tian init.d]# service mysql start
启动成功：
也可以:
  1.  
    [root@Tony_ts_tian init.d]# mv mysql mysqld
  2.  
    [root@Tony_ts_tian init.d]# service mysqld start

查看路径：mysql-bin.index多余文件，auto.cnf和performance_schema等不存在（文件不全）。（以上为成功后的mysql数据库目录）

解决5：
因为以前存在的MySQL卸载不干净导致。
删除和卸载（以下是的解决），然后重新安装：CentOS下MySQL的彻底卸载
