mysql在rancher上完成大庫的部署

1. 上兩篇部落格*(,)寫了資料庫的部署流程,的,可以有這兩種方法:
第一種方法中,dockerfile需要把每一步的操作打包成要給映象完成操作,有時候公司等其他情況限制,每一層的大小不能超過一定限制,因此此種方式很容易在構建映象的時候失敗。
第二種方法中,對sql語句執行匯入操作,速度過慢,很容易在rancher平臺部署的時候超過初始化的最大時間限制,造成服務啟動失敗。
因此,針對以上兩種情況,採用了一個新的方式:
首先,根據如下命令,完成mysql的某個庫的打包。(如果某個包的大小都大於構建映象時候的一層的大小,那麼幹脆別部署了,找人先把這個限制去掉或者提高下)
第一步:資料庫部署方法: 都是在本地資料庫234上面執行: 匯出資料庫的壓縮檔案方法: (1)先 mkdir /var/lib/mysql-files/imdb 然後chmod -R 777 /var/lib/mysql-files/imdb (2)執行mysqldump --no-autocommit --opt -h172.19.57.234 -uroot -p123456 --tab /var/lib/mysql-files/imdb wisekg(資料庫名) (3)壓縮 cd /var/lib/mysql-files/ tar zcvf wisekg.tar.gz ./imdb 其中wisekg為庫名 若同時部署2個,需要對imdb進行更新名字;重複(1)-(3)步驟生成kb.tar.gz 最後將壓縮檔案放到ftp://ftp3.dc2.fzyun.io/wise/ai-nlp/mysql_server/中。 第二步:修改init.sh以及Dockerfile; init.sh中主要修改不同資料庫對應的/docker-entrypoint-initdb.d/imdb名字,以及資料庫的名字; Dockerfile中也是新增對應的資料庫壓縮檔案。
對應的dockerfile和init.sh分別為:
dockerfile:(會自動執行init.sh指令碼)
