一、统一修改blockahead值为1024
for curHost in `cat 256node| grep -v ‘^#‘ | cut -d‘=‘ -f1` ; do
echo $curHost
ssh $curHost "blockdev --setra 1024 /dev/sd*"
done
二、定时检测kafka积压脚本：
192.167.42.146
while true; do echo "Start..."; checkKafkaShow.sh 1 3 | egrep ‘VIP_CDR|DATE‘ ; echo "End..."; sleep 30; done
三、实时监控数据量变化：
对比备份数据与过滤数据增减情况：
[gdsignal@sbisrv17 kafkaCreaterVIP]$ watch -d -n 30 "du -sh /data/glassfish/bak ;du -sh /data/glassfish/merged"
[gdsignal@sbisrv17 kafkaCreaterVIP]$watch -d -n 30 "du -sh /data/glassfish/bak/* ;du -sh /data/glassfish/merged/*"
五、编辑操作
kafkaCreater/conf、kafkaCreaterVIP/conf的配置文件conf.xml
<partitionIndex>由6修改成8：
sed -i ‘s#<partitionIndex>6</partitionIndex>#<partitionIndex>8</partitionIndex>#g‘ conf.xml
查看修改是否成功
grep ‘<perLine>‘ conf.xml
六、批量创建目录：
192.168.35.197
192.168.35.198
192.168.35.199
192.168.35.201
192.168.35.202
192.168.35.203
192.168.35.204
192.168.35.205
192.168.35.221
192.168.35.222
192.168.35.223
192.168.35.224
192.168.35.232
192.168.35.234
192.168.35.236
192.168.35.237
for i in `cat /home/gdsignal/log/node.txt`;do
ssh $i "mkdir -p /data/glassfish/merged/{MLTE_SGS/{CITY_86020,CITY_860750,CITY_860755,CITY_860757,CITY_860769},MLTE_S6A/{CITY_86020,CITY_860750,CITY_860755,CITY_860757,CITY_860769},MLTE_S10S11/{CITY_86020,CITY_860750,CITY_860757},MLTE_S1_MME/{CITY_86020,CITY_860750,CITY_860755,CITY_860757,CITY_860769},MLTE_S1U/{CITY_86020,CITY_860750,CITY_860755,CITY_860757,CITY_860769},MLTE_S1U_DNS/{CITY_86020,CITY_860750,CITY_860755,CITY_860757,CITY_860769},MLTE_S1U_HTTP/{CITY_86020,CITY_860750,CITY_860755,CITY_860757,CITY_860769},MLTE_S1U_IM/{CITY_86020,CITY_860750,CITY_860755,CITY_860757,CITY_860769},MLTE_S1U_MMS/{CITY_86020,CITY_860750,CITY_860755,CITY_860757,CITY_860769},MLTE_S1U_RTSP/{CITY_86020,CITY_860750,CITY_860755,CITY_860757,CITY_860769},MLTE_S1U_VOIP/{CITY_86020,CITY_860750,CITY_860755,CITY_860757,CITY_860769}}"
done
for i in `cat /home/gdsignal/log/node.txt`;do
ssh $i "rm -rf /data/glassfish/merged"
done
七、删除目录下日志文件：
for curHost in 192.167.43.41 192.167.43.42 192.167.43.16 192.167.43.17 192.167.43.18 192.167.43.19 192.167.43.20 192.167.43.21 192.167.43.22 192.167.43.23;do
echo $curHost
ssh $curHost "find /var/log/kafka -mtime +3 -name "*.*" -exec rm -rf {} \;"
done
for curHost in 192.167.43.41 192.167.43.42 192.167.43.16 192.167.43.17 192.167.43.18 192.167.43.19 192.167.43.20 192.167.43.21 192.167.43.22 192.167.43.23;do
echo $curHost
ssh $curHost "df -h"
done
for i in 192.167.43.{41,42,21,22,23,16,17,18,19,20};do
echo $i
ssh $i "df -h;du -sh /var/log/kafka/"
done
八、批量查看目录
ll /sidata{1..12}
ll /sidata*/kafka*/ 或者 ll /sidata{1..12}/kafka-logs/
rm -rf /sidata*/kafka-logs/smart*
九、批量转移文件
for i in `ll MLTE_S1U_HTTP*|head -n 500|awk ‘{print $NF}‘`;do
scp $i 172.16.248.15:/tmp/123/
done
for i in `ll MLTE_S1U_HTTP*|head -n 5000|awk ‘{print $NF}‘`;do
scp $i 192.168.35.205:/data/tmp/
done
十、 统计列数
cat *.CVS |awk -F , ‘{print -NF}‘
cat *.dat |awk -F , ‘{print -NF}‘ |grep -v 113
十一、在一个文本的倒数第5行插入一段字符或1个文本
倒数第5行的行号是固定的吧？
sed -i ‘ni aaa‘ file
就是不确定倒数第5行行号才要这么写的
tac file | sed -i ‘5i aaa‘ file
