echo “java环境初始化开始”
#功能描述: Centos8.5系统自动初始化脚本
#自动配置:IP地址\Yum源\docer\docker-compose v2.7.0\ZSH\Portainer\Cockpit\zabbix-agent2\chronyd
#脚本执行方法
# 1.刚安装完的系统最好重启一下, 如果是虚拟机的一定要重启!!!
# 2.删除所有#开头的注释, vim打开本文件光标停在首行并执行”set ff=unix”回车一直过滤到最后一行,保存退出!
# 3.执行命令”bash 01Auto_default_v1.5.sh”
#程序: 01Auto_default_v1.5.sh
