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。
[plain] view
plain copy
[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

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）：
[plain] view
plain copy
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:
[plain] view
plain copy
[root@localhost install-files]# rpm -ivh MySQL-server-5.6.27-1.el6.x86_64.rpm --nosignature
问题3：
mysqld: unrecognized service
[plain] view
plain copy
[root@Tony_ts_tian init.d]# service mysqld start
mysqld: unrecognized service
解决3：
启动脚本文件mysql的目录
[plain] view
plain copy
[root@localhost install-files]# cd /etc/rc.d/init.d/
[root@localhost init.d]# ls
functions mysql netconsole network README
并没有mysqld：
[plain] view
plain copy
[root@Tony_ts_tian init.d]# service mysql start
启动成功：
也可以:
[plain] view
plain copy
[root@Tony_ts_tian init.d]# mv mysql mysqld
[root@Tony_ts_tian init.d]# service mysqld start
问题4：
[root@localhost install-files]# rpm -ivh MySQL-server-5.6.27-1.el6.x86_64.rpm --nosignature

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

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'.
You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag.
Also, the account for the anonymous user has been removed.
In addition, you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test database.
This is strongly recommended for production servers.
See the manual for more instructions.

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：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）：

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'.
You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag.
Also, the account for the anonymous user has been removed.
In addition, you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test database.
This is strongly recommended for production servers.
See the manual for more instructions.

New default config file was created as /usr/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
