python自動安裝mysql5.7

python版本：python2.6

centos版本：centos6.9

mysql版本：mysql5.7.19

安裝目錄路徑和數據目錄路徑都是固定，當然也可以自己修改

這個腳本的原理是，通過createmycnf.sh的shell腳本生成my.cnf，buffer pool大小等在shell腳本裏已經計算好，然後installmysql.py修改生成好的my.cnf裏的端口等變量

並根據my.cnf來初始化mysql，初始化完畢之後啟動mysql服務，並設置mysql的root用戶密碼，整個執行過程的日誌會保存在當前目錄下的installmysql.log

執行腳本前要先安裝MySQL-python

yum install -y MySQL-python

installmysql.py
