解決1:

出現以上安裝錯誤列表的原因是：系統已經安裝了其他版本的mysql-libs包和mysql資料庫檔案導致不相容。

[[email protected] install-files]# yum remove mysql-libs

執行之後，還要詳細檢查解除安裝MySQL安裝的所有檔案，否則在後續安裝發生各種錯誤:CentOS下MySQL的徹底解除安裝

問題2：

[[email protected]_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%]

解決2：

從 rpm版本 4.1 開始，在安裝或升級軟體包時會檢查軟體包的簽名。如果簽名校驗失敗，你就會看到類似以上的錯誤訊息：

注：新的、只針對檔案頭的簽名：錯誤訊息：error: Header V3 DSA signature: BAD, key ID 0352860f

注：沒有安裝合適的鑰匙來校驗簽名，訊息中就會包含 NOKEY：錯誤訊息：warning: V3 DSA signature: NOKEY, key ID 0352860f

由於yum安裝了舊版本的GPG keys造成的，解決辦法就是（設定後無效）：

rpm --import /etc/pki/rpm-gpg/RPM*

此簽名是檢驗安裝包的有效性和安裝性的。我直接跳過（安裝時不校驗，加--nosignature引數）檢驗安裝:

[[email protected] install-files]# rpm -ivh MySQL-server-5.6.27-1.el6.x86_64.rpm --nosignature

問題3：

mysqld: unrecognized service

  1. [[email protected]_ts_tian init.d]# service mysqld start

  2. mysqld: unrecognized service

解決3：

啟動指令碼檔案mysql的目錄

  1. [[email protected] install-files]# cd /etc/rc.d/init.d/

  2. [[email protected] init.d]# ls

  3. functions mysql netconsole network README

並沒有mysqld：

[[email protected]_ts_tian init.d]# service mysql start

啟動成功：

也可以:

  1. [[email protected]_ts_tian init.d]# mv mysql mysqld

  2. [[email protected]_ts_tian init.d]# service mysqld start

問題4：

[[email protected] install-files]# rpm -ivh MySQL-server-5.6.27-1.el6.x86_64.rpm --nosignature

解決4：

問題5：

[[email protected] mysql]# service mysql start

  13. drwxr-xr-x. 2 mysql mysql 6 Oct 11 23:19 test

檢視路徑：mysql-bin.index多餘檔案，auto.cnf和performance_schema等不存在（檔案不全）。（以上為成功後的mysql資料庫目錄）

解決5：

因為以前存在的MySQL解除安裝不乾淨導致。

  65. A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !

  66. You will find that password in '/root/.mysql_secret'.

  67. You must change that password on your first connect,

  68. no other statement but 'SET PASSWORD' will be accepted.

  69. See the manual for the semantics of the 'password expired' flag.

  70. Also, the account for the anonymous user has been removed.

  71. In addition, you can run:

  72. /usr/bin/mysql_secure_installation

  73. which will also give you the option of removing the test database.

  74. This is strongly recommended for production servers.

  75. See the manual for more instructions.

  76. Please report any problems at http://bugs.mysql.com/

  77. The latest information about MySQL is available on the web at

  78. http://www.mysql.com

  79. Support MySQL by buying support/licenses at http://shop.mysql.com

  80. New default config file was created as /usr/my.cnf and

  81. will be used by default by the server when you start it.

  82. You may edit this file to change server settings

檢查：

  1. [[email protected] install-files]# service mysql start

成功的安裝，日誌中顯示（建立兩個檔案）：
