MySQL 5.7.9 GA版本已经出来，目前VPS已更新完成，虽说不像修正版本号更新一样，直接把数据库目录移过去就好那么容易，但也不难。 这次更新了子版本号，过程顺利，没坑，启动有告警。（我是从MySQL 5.6.27更新而来） 说说第一个： [Warning] Insecure configuration for --secure-file-priv: Current value does not restrict location of generated files. Consider setting it to a valid, non-empty path. secure-file-priv这个参数主要是限制LOAD_FILE和LOAD DATA和SELECT … ，INTO OUTFILE报表到指定的目录。 一般来说很少用，默认值有empty、dirname、NULL，正确的意思就是：

Linux
前言 前幾天，看到Ubuntu 18.04出一段時間了，看是時機成熟了。 所以就把自己平常工作在用的ThinkPad筆電從Ubuntu 16.04升級到Ubuntu 18.04了。 當然，中途有遇到一些情況，讓升級的程序跟步驟變得有些複雜，所以這篇文章，就是在紀錄有關於升級的過程中遇到的問題提供日後大家做參考。 前置動作 當然，需要有一台Ubuntu 16.04主機，不然要怎麼升級成18.04 如果怕升級上去之後，發生一些無法預期的事情，則可以先備份，備份工具可以使用「CloneZilla」進行備份。 升級做法 先依照下面的指令去安裝所有套件的最新版本。 12345sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade 接著按照下面的指令去檢查可以升級的版本 1sudo do-release-upgrade -c 那麼，就可以找到「Ubuntu 18.04」的發行版本

一開始用之前制作的USB DOS開機碟來處理Dell隨機附的硬碟firmware更新, 但在R720xd上卻不能用會直接顯示重開機或換碟 後來跟利用iDrac上的UI找到物理碟盤展開後可以查到硬碟型號與相關的資訊, 拿查到的型號在Dell網站搜尋找到一檔案 Nautilus_efi_A12_ZPE.exe 執行後解開有一工具程式可以使用256MB or 大一點的容量來制作工具碟, 我用16GB的碟反而不認得, 後來是找了2GB的碟或真的用256MB的就可以被偵測到並寫入檔案https://www.dell.com/support/home/ae/en/aedhs1/drivers/driversdetails?driverid=wmkvj 一關始我以為這個碟可以像之前的工具碟一樣直接開機, 發現並不行又試著用工具程式製作了ISO檔並用iDrac上的虛擬光碟機掛開機開機也不行經檢查發現此ISO檔很小只包了開機部份沒有其他內容檔案 最後因為上面的檔案名有efi副檔名, 讓我聯想到之前幫同事利用Dell UEFI boot Uility UI選efi檔案來
