前言

前面安裝過mysql5.6，時隔三個月，開發那邊反饋需要在MySQL中處理JSON類型的數據，查看文檔，JSON是在5.7支持的新特性。于是著手安裝Mysql57
Mysql5.6.28的安裝：//www.jb51.net/article/103743.htm

安裝

若使用apt-get install mysql-server進行安裝，默認安裝的不是最新的版本，于是考慮去官網找一個最新的社區版本。

1.獲取最新的Mysql版本

在 https://dev.mysql.com/downloads/mysql/ 下選擇操作系統版本（本例為Ubuntu），下載的時候注意要和操作系統版本相匹配（OS版本對應安裝包版本）。

# cat /etc/issueUbuntu 12.04.5 LTS /n /l# wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-server_5.7.17-1ubuntu12.04_amd64.deb-bundle.tar

2.具體安裝（因為依賴報的關系，需要注意安裝次序）

基本配置（和以前的5.6版本有差異）

1.新增用戶，賦權
