Python腳本安裝MySQL5.7 - Time.catcher - 博客園
https://www.cnblogs.com/weiwenbo/p/6640605.html

 

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，固然也能夠本身修改

這個腳本的原理是，經過createmycnf.sh的shell腳本生成my.cnf，buffer pool大小等在shell腳本里已經計算好，而後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，初始化完畢以後啓動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

 

注意：目前不支持多實例安裝，只支持單實例安裝

 

執行腳本前要先安裝MySQL-python

yum install -y MySQL-python
 

 

installmysql.py

installmysql.py腳本參數

-P：mysql端口號
-f：mysql二進制安裝包位置
-b：createmycnf.sh文件的位置
-p：mysql的root用戶密碼
