看到 Percona 09/27 開始釋出整合資源
Percona server for MySQL Alpha Build of Percona Server 8.0 released
實在見獵心喜,原以為 Percona 拿完 MariaDB 的 Sponsor of the MariaDB Foundation 後可能會面臨一次大改版或是新產品
接著就是看到 Percona Server for MySQL 8.0 實在太開心
因為肯定可以吸收到很多 MySQL 5.7 migrate to MySQL 8.0 的測試報告
想當然手癢也試了一下文件內的說明
除了 Available for the following platforms 資訊外
看到 Fixed Bugs 的想法是已經 Beta 過一陣子了,只是自己還沒跟上而已
至於 Unfinished Features & Known Issues 也都是 MySQL 等相關功能面的參考指標,但不在本文討論劃下
我們先把相關參數拉出來研究看看,因為已經 Docker 化,基本上安裝方便已經減少很多困擾
從官方建議的指令來看,Docker Image 放在 Docker hub 上不算難找 (perconalab/percona-server:8.0.12.alpha)
真心深入研究的話,看看 Percona Server for MySQL 的 8.0 branch 也是沒問題的
首先把 Docker Image 拉回來
root@docker-instance:~# docker run -d -e MYSQL_ROOT_PASSWORD=password -p 3306:3306 perconalab/percona-server:8.0.12.alpha Unable to find image 'perconalab/percona-server:8.0.12.alpha' locally 8.0.12.alpha: Pulling from perconalab/percona-server 256b176beaff: Pull complete 29bf6e451a3d: Pull complete 47794ac16dab: Pull complete 33380263e15d: Pull complete 181f75c0b311: Pull complete 6e4d3e48573b: Pull complete 9fe659f8c468: Pull complete Digest: sha256:bc29684620d4211defb84cfb2f3abf37fb7331350a8395b44bd3dc525fe2a5df Status: Downloaded newer image for perconalab/percona-server:8.0.12.alpha 3985e22666153615357292ece5f215950dfc3e081884dcd9f41f88f74236dd42
接著把 MySQL 8.0 服務帶起來確認版號

看起來沒什麼問題後,先備份留存預設設定,未來再來進行壓力測試
