##   如果已经安装过某个软件，就会不进行安装这个软件     ####################
##   所有的软件都会安装到   /usr/软件名  对应的目录下   ####################

##          1.安装JDK1.8的版本
##          2.安装git
##          3.安装maven3.6.0版本
##          4.安装mysql8.0版本（注意，这个过程让你选择安装的版本。默认是8.0，还有5.7等版本。这个启动会让你输入root的密码信息）
##          5.安装redis5.0版本（可以选择不安装，将isinstallredis的值改为false）
##          6.安装rocketMQ4.3版本（可以选择不安装，将isinstallrocketmq的值改为false）
##          7.安装nodejs10.13.0版本
