python自动安装MysqL5.7

python版本：python2.6

centos版本：centos6.9

MysqL版本：MysqL5.7.19

安装目录路径和数据目录路径都是固定，当然也可以自己修改

这个脚本的原理是，通过createmycnf.sh的shell脚本生成my.cnf，buffer pool大小等在shell脚本里已经计算好，然后installMysqL.py修改生成好的my.cnf里的端口等变量

并根据my.cnf来初始化MysqL，初始化完毕之后启动MysqL服务，并设置MysqL的root用户密码，整个执行过程的日志会保存在当前目录下的installMysqL.log

注意：目前不支持多实例安装，只支持单实例安装

执行脚本前要先安装MysqL-python

yum install -y MysqL-python

installMysqL.py

installMysqL.py脚本参数

-P：MysqL端口号
-f：MysqL二进制安装包位置
-b：createmycnf.sh文件的位置
-p：MysqL的root用户密码

 创建必要的目录
 makeDIR(port):

        logger.error(MysqL %s already install port)
        sys.exit(1)

 解压二进制安装包
 extract(MysqLfile):

 拷贝安装包文件到程序目录
 copyFile(MysqLfile):
    shutil.copytree(MysqLfile.split(.tar.gz)[0],MysqL_INSTALL_DIR)
    shutil.copy2(MysqL_INSTALL_DIR + support-files/MysqL.serverMysqL_STARTUP_SCRIPT)
