脚本支持 5.7 与 8.0 的二进制包的安装
脚本执行方式：
./installMysql.sh /opt/mysql-5.7.30-linux-glibc2.12-x86_64.tar.gz 3306
1.运行脚本 installMysql.sh
2.传入mysql安装包路径
3.传入mysql准备设置的端口 3306/3307等
默认安装路径
安装路径可以根据需求更改，只需要更改如下:
mysql_basedir="/usr/local"
mysql_datadir="/data/mysql$mysql_port"
mysql_tmpdir="/data/tmpdir"
my_cnf_dir="/data"
mysql 解压文件路径，与mysql程序路径
/usr/local/mysql
/usr/local/mysql-version-linux-glibc2.12-x86_64数据文件存放路径
/data/mysql+指定的端口临时文件存放路径
/data/tmpdir
installMysql.sh
#!/bin/bash
