1、iptables的配置文件位置:/etc/sysconfig/iptables
主控機:即業務運行中的機子;備份機:即主控機故障時,切換到備份的機子
--在主控機上的操作-------------------
2、建立目錄:
復制代碼代碼如下: mkdir -p /bak/iptables/</p>
<p> mkdir /root/script/
3、在/root/script/目錄下建立腳本:
復制代碼代碼如下: vi backup.sh</p>
<p> cp /etc/sysconfig/iptables /bak/iptables/iptables_$(date +%Y%m%d%H)
4、定制自動任務:
復制代碼代碼如下: crontab -e</p>
<p> */10 * * * * /usr/sbin/ntpdate 210.72.145.44</p>
<p> 10 * * * * sh /root/script/backup.sh
--在備份機上操作---------------------
5、建立目錄:
復制代碼代碼如下:mkdir -p /bak/iptables/{lt,yd} #lt目錄放聯通跳轉的備份,yd目錄放移動跳轉的備份</p>
<p> mkdir /root/script/
6、在/root/script/目錄下建立腳本:
復制代碼代碼如下:vi scp_lt.sh</p>
<p> #!/usr/bin/expect -f</p>
<p> set password gst</p>
<p> spawn scp -P 22 [email protected]:/etc/sysconfig/iptables /bak/iptables/lt/iptables</p>
<p> set timeout 300</p>
<p> expect "[email protected]'s password:"</p>
<p> set timeout 300</p>
<p> send "$passwordr"</p>
<p> set timeout 300</p>
<p> send "exitr"</p>
<p> expect eof
7、在/root/script/目錄下建立腳本:
復制代碼代碼如下: vi scp_yd.sh</p>
<p> #!/usr/bin/expect -f</p>
<p> set password gst</p>
<p> spawn scp -P 22 [email protected]:/etc/sysconfig/iptables /bak/iptables/yd/iptables</p>
<p> set timeout 300</p>
<p> expect "[email protected]'s password:"</p>
<p> set timeout 300</p>
<p> send "$passwordr"</p>
<p> set timeout 300</p>
<p> send "exitr"</p>
<p> expect eof
8、在/root/script/目錄下建立腳本:
復制代碼代碼如下: vi backup.sh</p>
<p> expect /root/script/scp_lt.sh</p>
<p> expect /root/script/scp_yd.sh</p>
<p> sed -i 's/202.105.135.52/183.62.178.85/g' /bak/iptables/lt/iptables</p>
<p> sed -i 's/58.251.49.18/58.250.56.154/g' /bak/iptables/lt/iptables</p>
<p> cp /bak/iptables/lt/iptables /etc/sysconfig/iptables</p>
<p> /etc/init.d/iptables restart</p>
<p> /etc/init.d/iptables save</p>
<p> mv /bak/iptables/lt/iptables /bak/iptables/lt/iptables_$(date +%Y%m%d%H)</p>
<p> mv /bak/iptables/yd/iptables /bak/iptables/yd/iptables_$(date +%Y%m%d%H)
9、注意,要在備份機上手動遠程登陸一次,以獲得RSA的公鑰,之後就不用這樣登陸了,否則腳本會執行錯誤
10、定制自動任務:
復制代碼代碼如下: crontab -e</p>
<p> */10 * * * * /usr/sbin/ntpdate 210.72.145.44</p>
<p> 20 * * * * sh /root/script/backup.sh
