最近一個項目要部署在阿裡雲上，為了開發團隊方便，我自費買了個ECS，先裝個資料庫給開發用。 因為之前都是在真機安裝，與這次阿裡雲上的部署比起來，還是有點區別的。 Mysql 1 安裝mysql版本包 wget https://dev.mysql.com/get/mysql57-community-r ...

Mysql
1 安裝mysql版本包
wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
yum install mysql57-community-release-el7-11.noarch.rpm
vim /etc/yum.repos.d/mysql-community.repo
把5.6的enable置為1，5.7的置為0
2 安裝mysql：
yum install mysql mysql-community-server -y
# 建立慢查詢日誌文件，如果沒有安裝時候會報錯
touch /var/log/slow.log
#給mysql用戶授權這個文件
chown mysql:mysql slow.log

因為是開發環境，沒有壓力，所以沒進行優化，實際生產時候innodb_buffer_pool_size 參數非常重要，一定要加大到記憶體70%-80%，之前吃過虧。
3 報錯
