#|          此脚本分有离线安装和联网安装的功能, 联网安装的用法就是直接运行这个脚本 sh ***.sh /或者./***.sh        |#

#|  而离线安装， 就是把安装包和这个脚本放在想安装在的目录， 然后执行sh ***.sh /或者./***.sh即可，而无论选择哪一   |#

#|      方式，都是包是否存在的问题，包在=离线，包不在=联网，下面说一下上面的全局变量的解释。                      |#

#|        onversion    这个是在联网安装的时候需要制定的版本，默认4.0.3，如果需要安装5.0.0的， 修改此参数。        |#

#|        offversion   这个不用管它，这个是离线安装识别离线包版本的。                                             |#

#|        cluster_name 这个就是安装集群的文件夹名字，就是把集群装在这个文件夹里面。                               |#

#|        number       这个就比较重要了， 节点。一台机器需要安装的节点，我这里是6，安装6个节点，可修改。          |#

#|        numstaring   这个是端口的前缀，比如我这里安装6个节点，端口自动分配为7001,7002,7003...， 如果需要修改成  |#

#|                     6001,6002...这些端口，修改此属性为600便可。                                                |#
