1.1 backup.sh // 目录备份（数据备份）
该脚本将/data目录备份到/backup目录下，并以当前时间为文件名进行压缩。同时，该脚本会删除7天前的备份文件。可以使用crontab命令将该脚本设置为定时任务，例如每天凌晨3点执行一次备份：
0 3 * * * /xx/xx/backup_script.sh
#!/bin/bash
# 定义备份目录和备份文件名
backup_dir="/backup"
backup_file="data_backup_$(date +%Y%m%d%H%M%S).tar.gz"
# 定义要备份的目录
backup_source="/data"
# 创建备份目录
if [ -d $backup_dir ]; then
echo "存在目录$backup_dir"
else
mkdir -p $backup_dir
fi
# 执行备份
tar -czf $backup_dir/$backup_file $backup_source 2>/dev/null
# 删除7天前的备份文件
find $backup_dir -name "data_backup_*" -type f -mtime +7 -exec rm {} \;
1.2 check_ip.sh // 检查ip
for i in `cat ip`
do
if ping -c 1 $i &>/dev/null; then
echo -n $i && echo -e \\t "\033[32m connect success \033[0m"
else
echo -n $i && echo -e \\t "\033[31m connect failed \033[0m"
fi
done
1.3 FlotMonitor.sh // 流量监控
该脚本使用 ifconfig 命令获取 eth0 网络接口的接收和发送流量，并将其转换为千字节（KB）。然后，该脚本输出当前时间和接收/发送流量，并等待指定时间后再次获取流量数据。
#!/bin/bash
# 设置监控间隔（秒）
INTERVAL=5
while true
do
# 获取当前时间
now=$(date +"%T")
# 使用 ifconfig 命令获取 eth0 网络接口的接收和发送流量
rx=$(ifconfig eth0 | grep 'RX packets' | awk '{print $5}')
tx=$(ifconfig eth0 | grep 'TX packets' | awk '{print $5}')
# 将字节转换成千字节
rxk=$(echo "scale=2;$rx/1024"|bc)
txk=$(echo "scale=2;$tx/1024"|bc)
# 输出当前时间和接收/发送流量
echo "$now RX: $rxk KB/s TX: $txk KB/s"
# 等待指定时间
sleep $INTERVAL
done
1.4 ssh_NoPasswd.sh // 集群免密
#!/bin/bash
SSH='/root/.ssh'
if [ ! -d $SSH ];then
mkdir -p $SSH
chmod 700 $SSH
fi
if [ ! -e $SSH/id_rsa.pub ];then
ssh-keygen -t rsa -f /root/.ssh/id_rsa -P ''
fi
if [ -f $SSH/authorized_keys ];then
cat $SSH/id_rsa.pub >> $SSH/authorized_keys
else
