在tomcat中安装logback插件，此插件用于生成日志。该日志中包括很多信息，我们的目的是将需要的数据进行整理，将其插入到mysql数据库中，并将其做成定时任务执行。
一下是原日志文件内容：
我们需要client,uniquecode,device,versioncode,interface,createtime这些字段
思路如下：
1.我们只需要对包含接口和请求开始字段的行进行数据整理。
grep "personal/checkupdate.json请求开始" /home/logs/fight_cancer_interface/info.2014-05-19.log
2.我们要确定这些行中必须包括client,uniquecode,device,versioncode,interface,createtime这些字段。
grep "personal/checkupdate.json请求开始" /home/logs/fight_cancer_interface/info.2014-05-19.log|grep "client="|grep "uniquecode="|grep "device="|grep "client="|grep "versioncode="
3.需要将多余的字段删除
grep "personal/checkupdate.json请求开始" /home/logs/fight_cancer_interface/info.2014-05-19.log|grep "client="|grep "uniquecode="|grep "device="|grep "client="|grep "versioncode="|awk -f"请求开始--:" '{print $1,$2}'|awk -f"info com.wyqj.fightcancer.intercepter.loginterceptor - /fight_cancer_interface/" '{print $1,$2}'|awk -f".json" '{print $1,$2}'|awk -f"[" '{print $1,"@@@###",$2}'|awk -f"]" '{print $1,"@@@###",$2}'|awk -f'@@@###' '{print $1,$3}'|sed 's/personal\/checkupdate/personal_checkupdate/g' | awk -f ",[[:digit:]][[:digit:]][[:digit:]]" '{print $1,$2}'|sed "s/ {/,/g"|sed "s/ personal/,personal/g"|sed "s/}//g"|awk -f"," '{print $6","$3","$5","$7","$2","$1");"}'|sed "s/,/\',\'/g"|sed "s/);/\');/g"|sed "s/^/\'/g"
4.将最前面加入数据库插入语句
grep "personal/checkupdate.json请求开始" /home/logs/fight_cancer_interface/info.2014-05-18.log|grep "client="|grep "uniquecode="|grep "device="|grep "client="|grep "versioncode="|awk -f"请求开始--:" '{print $1,$2}'|awk -f"info com.wyqj.fightcancer.intercepter.loginterceptor - /fight_cancer_interface/" '{print $1,$2}'|awk -f".json" '{print $1,$2}'|awk -f"[" '{print $1,"@@@###",$2}'|awk -f"]" '{print $1,"@@@###",$2}'|awk -f'@@@###' '{print $1,$3}'|sed 's/personal\/checkupdate/personal_checkupdate/g' | awk -f ",[[:digit:]][[:digit:]][[:digit:]]" '{print $1,$2}'|sed "s/ {/,/g"|sed "s/ personal/,personal/g"|sed "s/}//g"|awk -f"," '{print $6","$3","$5","$7","$2","$1");"}'|sed "s/,/\',\'/g"|sed "s/);/\');/g"|sed "s/^/\'/g"|sed 's/^/insert into `fight_cancer`.`tb_statistics_base_info` (`client`,`uniquecode`,`device`,`versioncode`,`interface`,`createtime`) values (/g'|sed "s/client=//g"|sed "s/uniquecode=//g"|sed "s/device=//g" |sed "s/versioncode=//g"
5.将这些sql语句生成.sql文件
grep "personal/checkupdate.json请求开始" /home/logs/fight_cancer_interface/info.2014-05-18.log|grep "client="|grep "uniquecode="|grep "device="|grep "client="|grep "versioncode="|awk -f"请求开始--:" '{print $1,$2}'|awk -f"info com.wyqj.fightcancer.intercepter.loginterceptor - /fight_cancer_interface/" '{print $1,$2}'|awk -f".json" '{print $1,$2}'|awk -f"[" '{print $1,"@@@###",$2}'|awk -f"]" '{print $1,"@@@###",$2}'|awk -f'@@@###' '{print $1,$3}'|sed 's/personal\/checkupdate/personal_checkupdate/g' | awk -f ",[[:digit:]][[:digit:]][[:digit:]]" '{print $1,$2}'|sed "s/ {/,/g"|sed "s/ personal/,personal/g"|sed "s/}//g"|awk -f"," '{print $6","$3","$5","$7","$2","$1");"}'|sed "s/,/\',\'/g"|sed "s/);/\');/g"|sed "s/^/\'/g"|sed 's/^/insert into `fight_cancer`.`tb_statistics_base_info` (`client`,`uniquecode`,`device`,`versioncode`,`interface`,`createtime`) values (/g'|sed "s/client=//g"|sed "s/uniquecode=//g"|sed "s/device=//g" |sed "s/versioncode=//g" > 2014-05-18.sql
6.将sql文件生成数据库
mysql -u用户名 -p密码 数据库名 < 2014-05-18.sql
7.完善脚本
#!/bin/bash
#dates=`date +%y-%m-%d`
dates=`date -d"1 days ago" +%y-%m-%d`
path_log=/home/logs/fight_cancer_interface/info.$dates.log
path_sql=/home/sql/$dates.sql
grep "personal/checkupdate.json请求开始" $path_log|grep "client="|grep "uniquecode="|grep "device="|grep "client="|grep "versioncode="|awk -f"请求开始--:" '{print $1,$2}'|awk -f"info com.wyqj.fightcancer.intercepter.loginterceptor - /fight_cancer_interface/" '{print $1,$2}'|awk -f".json" '{print $1,$2}'|awk -f"[" '{print $1,"@@@###",$2}'|awk -f"]" '{print $1,"@@@###",$2}'|awk -f'@@@###' '{print $1,$3}'|sed 's/personal\/checkupdate/personal_checkupdate/g' | awk -f ",[[:digit:]][[:digit:]][[:digit:]]" '{print $1,$2}'|sed "s/ {/,/g"|sed "s/ personal/,personal/g"|sed "s/}//g"|awk -f"," '{print $6","$3","$5","$7","$2","$1");"}'|sed "s/,/\',\'/g"|sed "s/);/\');/g"|sed "s/^/\'/g"|sed 's/^/insert into `fight_cancer`.`tb_statistics_base_info` (`client`,`uniquecode`,`device`,`versioncode`,`interface`,`createtime`) values (/g'|sed "s/client=//g"|sed "s/uniquecode=//g"|sed "s/device=//g" |sed "s/versioncode=//g" > $path_sql
mysql -u用户名 -p密码 数据库名 < $path_sql
8.将此脚本做成定时任务
crontab -e
[注]这里我做了两个定时任务，这里需要注意的是，23点59分执行数据库备份脚本，01点01分执行日志整理脚本。日志整理脚本必须在数据库备份脚本执行之后执行。因为如果日志文件过大，需要很长时间执行，如果在其还没执行完就进行数据库备份，可能会出现问题。
这个脚本需要熟练运用sed和awk，通过此脚本也看出了sed和awk功能的强大。我之前尝试使用cut命令进行数据分割，都没能如愿。希望以后能更深入地学习sed和awk，并能够掌握sed和awk编程。
