我使用 mysql57-community-release-el6-7.noarch.rpm Repo 在 RHEL 6.5 上安裝了 Mysql server 5.7.9。並且安裝成功，但是當我嘗試啟動它並給出錯誤時。從 /var/log/mysqld.log 我得到這些日誌

任何建議這個錯誤在說什麼……

MySQL 伺服器無法訪問您的 /tmp 目錄，無法寫入和創建臨時文件。確保 /tmp 目錄歸 root 使用者所有，並且在 /tmp 目錄上設置了粘滯位。鍵入以下命令來修復此錯誤。您必須以 root 使用者身份登錄並輸入：

chown root:root /tmp

chmod 1777 /tmp

測試一下

/etc/init.d/mysqld 啟動

> [ERROR] InnoDB: Unable to create temporary file; errno: 13

這條線在那裡看起來有問題。嘗試檢查/tmpdir 是否存在（它應該）並且可用於 mysql 使用者（或您使用的使用者）。您可以嘗試--tmpdir在配置中使用不同的路徑或選項，更多資訊見 docs）。

SELinux 也可能有問題（如果它處於強制模式）。ausearch -ts today -m avc | audit2allow如果 /tmp 目錄沒有為 mysql 阻止，請檢查您的審核日誌（例如，使用）。對於測試，您可以使用setenforce 0.
