rsync定时同步
环境配置
关闭防火墙，selinux
systemctl stop firewalld
systemctl disable firewall
setenforce 0
cat /etc/selinux/configpei
SELINUX=disable
设置主机名
systemctl set-hostname code
systemctl set-hostname backup
设置静态IP
rsync由于要设置定时同步，所以要配置DNS，时钟完全同步
cd /etc/sysconfig/network-scirpts
ls
cat ifcfg-ens33
vim ifcfg-ens33ROUTERPUTE=none
IPADDR=192.168.235.6
GATEWAY=192.168.235.254
#和虚拟机网关一致
DNS1=8.8.8.8
关闭NetworkManager
systemctl stop NetworkManager
systemctl disable NetworkManager
systemctl status NetworkManager
配置YUM源
#备份
cd /etc/yum.repos.d
tar -zcf repo.tar.gz *repo
rm -rf *.repo
#挂载
rm rf /mnt/*
mount -o ro /dev/sr0 /mnt
lsblk
chmod +x /etc/rc.local
echo 'mount -o ro /dev/sr0 /mnt'>>/etc/rc.local
