1. Create a directory dedicated to the execution of the installation script, and create the directory required for the compressed file in this directory

mkdir -p /opt/shell/files
cd /opt/shell
vi mysql_install.sh

2. Edit shell script

#!/bin/bash
#离线安装mysql
#我们需要安装mysql的目录
ipath="/usr/local"
#获取当前脚本目录的路径 $0-shell本身的文件名
installpath=$(cd `dirname $0`; pwd)
echo ${
    
    installpath}
#提前在脚本目录创建files文件夹 上传安装包到该目录
filepath=${
    
    installpath}/files
j=`ps -el | grep mysqld`
#查看是否已经安装mysql
mysql=$(echo ${
    
    j} | grep "mysqld")
echo ${
    
    mysql}
if [[ "$mysql" != "" ]]
then
	echo "mysql was installed!"
else
	echo "mysql not installed!"
	echo "开始解压mysql安装包"
	tar -xzvf ${
    
    filepath}/mysql-*.tar.gz > /dev/null 2>&1
	echo "进入mysql安装目录 获取mysql版本"
	cd mysql* && mysqlname=`pwd | awk -F '/' '{print $NF}'`
