- #test the cdn ip loop
- for((i=1;i<=60;i++));do
- ping -c 1 *.cdns.com | grep -v PING | grep -i 'from' | awk '{print $4}' | sed -r 's/(:)|(\-BJ\-CNC)//g'
- done
测试
- ./cdn-loop.sh | sort | uniq -c
- 20 123.1.1.1
- 20 123.1.2.2
- 20 21.1.3.3
4 测试 apache vhost
- grep -vE '^#|^[ \t].&#' httpd-vhosts.conf | grep ServerName | awk '{print $2}' >> bbs_vhost.txt
- while read line;do dig $line | grep -E 'IN.*A|IN.*CNAME'|grep -v '^;';done < bbs_vhost.txt

5 批量上传ssh id_rsa.pub 公匙
自动: 需要使用 expect 命令
- cat auto_ssh_key.sh
- #!/bin/bash
- #auto ssh key
- #20111125 by dongnan
- #variables
- hosts='2 3 4 5 6 7 8 9'
- ip=10.100.100.
- user=dn
- password=mima
- #function
- 参考
- auto_ssh_copy_id () {
- expect -c "set timeout -1;
- spawn ssh-copy-id -i /home/dn/.ssh/id_rsa.pub $1;
- expect {
- *(yes/no)* {send -- yes\r;exp_continue;}
- *assword:* {send -- $2\r;exp_continue;}
- eof {exit 0;}
- }";
- }
- for i in $hosts;do
- echo "${ip}$i"
- # cat ~/.ssh/id_rsa.pub | ssh dn@${ip}$i "mkdir -p ~/.ssh && chmod 700 ~/.ssh && cat - >~/.ssh/authorized_keys && chmod 644 ~/.ssh/authorized_keys"
- auto_ssh_copy_id $user@${ip}$i $password
- done
6 批量部署 .bash_profile ,前提需要 ssh通过私匙登陆ssh服务器
关于如何配置ssh key,请参考这里!
- $ grep -E 'space.$|bbs.$' /etc/hosts | awk '{print $1}' > hosts
- $ while read line;do echo $line;scp ~/.bash_profile dn@${line}:/home/dn/;done < hosts
- 10.100.100.2
- .bash_profile 100% 622 0.6KB/s 00:00
- 10.100.100.3
- .bash_profile 100% 622 0.6KB/s 00:00
- 10.100.100.4
- .bash_profile 100% 622 0.6KB/s 00:00
- ......
7 stdin and while
- cat install.log | while read line;do echo $line ; wc -c;done
- while read line;do echo $line | wc -c;done < install.log
8 自定义.bash_profile 文件!
- #将以下行添加到.bash_profile
- ip=$(/sbin/ifconfig eth1 | grep Bcast | sed -e 's/^.* addr:\(.*\) Bcast.*$/\1/')
- if [ $ip ];then
- PS1="\[\e[32;1m\]$ip\[\e[0m\][\W]\$ "
- export PS1
- fi
- echo "[LOAD]";cat /proc/loadavg;echo "[DISK]";df -Th
9 统计用户登陆次数与 ip 地址
- #!/bin/bash
- #chek login user
- #
- #variables
- user=`id -u`
- #
- if [ $user -ne 0 ];then
- echo "must root !!"
- exit 1
- fi
- for i in `ls /var/log/secure*`;do
- echo "$i"
- #cat /var/log/secure | grep -i ' Accepted password' | awk '{print $9, $11}' | sort | uniq -c
- cat "$i" | grep -i ' Accepted password' | awk '{print $9, $11}' | sort | uniq -c
- done
效果如下
- ./login.sh
- /var/log/secure
- 6 dn 100.100.100.99
- /var/log/secure.1
- 15 dn 100.100.100.99
10 统计bbs 文件夹大小,需要ssh-key 参考上面!
- #!/bin/bash
- #du -sh
- #variables
- ip=100.100.100.
- #hosts='24'
- hosts='22 23 24 25 26 27 28 29'
- for host in $hosts;do
- echo ${ip}$host
- ssh ${ip}$host "find /var/www/bbs/ -type d -name 'day*' | xargs du -h | awk '{print \$1}'"
- ssh ${ip}$host "du -sh /var/www/bbs/"
- done
#ssh 传递 awk 命令时 "$" 需要使用"\"转义字符,例如:
- ssh ${ip}$host "df -h | grep -E '^/dev.*(/|/usr|/var)$' | awk '{print \$5,\$6}'"
#统计硬盘使用情况
- cat bbs_df.sh
- #!/bin/bash
- #vdisk usage
- #20111129 by dongnan
- #variables
- ip=10.100.100.
- #hosts='102'
- hosts='102 103 104 105 106 107 108 109'
- for host in $hosts;do
- echo -en "${ip}$host "
- ssh ${ip}$host "df -h | grep -E '^/dev.*(/|/usr|/var)$' | awk '{print \$6,\$5}'"
- done

- #Usage : haproxy [-f <cfgfile>]* [ -vdVD ] [ -n <maxconn> ] [ -N <maxpconn> ]
- # [ -p <pidfile> ] [ -m <max megs> ]
- # -v displays version ; -vv shows known build options.

- # -V enters verbose mode (disables quiet mode)
- # -D goes daemon
- # -q quiet mode : don't display messages
- # -c check mode : only check config files and exit
- # -n sets the maximum total # of connections (2000)
- # -m limits the usable amount of memory (in MB)
- # -N sets the default, per-proxy maximum # of connections (2000)
- # -p writes pids of all children to this file
- # -de disables epoll() usage even when available
- # -ds disables speculative epoll() usage even when available
- # -dp disables poll() usage even when available
- # -sf/-st [pid ]* finishes/terminates old pids. Must be last arguments.

- for i in `seq $1`

- 使用方法很简单,参数3表示消耗3颗CPU的资源,运行后,会有一堆 kill 命令,方便 kill 进程:
- [root@test02 ~]# ./killcpu.sh 3
- kill 30104 ;
- kill 30106 ;

- #1 添加了简单容错功能,80端口故障后会再检查多次,如果故障次数超过规定的失败次数,则认定haproxy 失败,否则认定haproxy 正常;举个例子比如haproxy 并发比较大,没有向应监控脚本的请求,监控脚本记录失败次数1,依次执行10次,如果监控失败次数小于5(比如1次),则认为haproxy 正常,进入下次的监控,而不是像0.2版监控脚本一样,只要有一次80端口故障立马就切换了!
- #2 为了方便keepalived.sh 调用此脚本,将脚本写成daemon形式可以设定监控脚本检查间隔时间(默认2s执行一次),不再需要依赖crontab来执行了,为方便调试脚本添加以启动和关闭监控脚本功能!
