第一步：修改成阿里云源
1、mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
2、curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

第二步： 下载sk5.sh文件 到服务器的root目录，并且改成权限为：rwxr-xr-x 意思就是每行最后一个打对号
脚本:wget -qO /root/sk5.sh http://chao.kaiuu.cn/sh/sk5-kehu/sk5.sh && chmod +x /root/sk5.sh

第三步：运行./sk5.sh 即可自动搭建完成

综合脚本：wget -qO /root/sk5.sh http://chao.kaiuu.cn/sh/sk5-kehu/sk5.sh && chmod +x /root/sk5.sh && bash /root/sk5.sh

超级综合脚本：yum -y install wget && wget -qO /root/sk5.sh http://chao.kaiuu.cn/sh/sk5-kehu/sk5.sh && chmod +x /root/sk5.sh && bash /root/sk5.sh

删除记录：history -c && rm -rf /root/sk5.sh

搭建完成后都复制下来，转成老鱼格式
