centos6.5 mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz 脚本化安装

1.下载mysql安装包:https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz 

2.将下面的脚本复制到sh脚本文件中,后缀为.sh哦，如:mysql_install.sh,特别注意要是在windows上面操作复制粘贴,需要使用notepadd++把换行符替换为\n,因为windows换行符为\r\n,linux为\n

3.将下载下来的安装包和mysql_install.sh 两个文件放在一个目录,上传到centos6.5系统/home,然后执行mysql_install.sh文件,3分钟左右方可安装完成；

4.安装完成,登陆用户密码为:root:root,并已设置远程可登陆,可直接在windows上面下载个navcat连接；
