本次模拟系统，是利用Hadoop等组件来模拟巨型日志的处理系统，包括Python定时、Flume收集日志、MR处理日志、Sqoop导出数据、Hive的简单统计等，具体的架构如下：
一、项目架构
二、数据源下载
数据源我也是从csdn上下载的日志数据，想要的可以留下邮箱！
【注意：如何搞定时间不同，复制的文件也不同】
from datetime import date, time, datetime, timedelta
import os
def work(i):
if i>13:
data_path='/home/hadoop/LogModel/data/ex0412'+str(i)+'.log'
os.system("sudo cp "+data_path2+" /home/hadoop/LogModel/source/")
if i<10:
data_path='/home/hadoop/LogModel/data/ex05010'+str(i)+'.log'
os.system("sudo cp "+data_path2+" /home/hadoop/LogModel/source/")
if i>9 or i<14:
data_path1='/home/hadoop/LogModel/data/ex0412'+str(i)+'.log'
os.system("sudo cp "+data_path1+" /home/hadoop/LogModel/source/")
data_path2='/home/hadoop/LogModel/data/ex0501'+str(i)+'.log'
os.system("sudo cp "+data_path2+" /home/hadoop/LogModel/source/")
def runTask(func, day=0, hour=0, min=0, second=0):
# Init time
now = datetime.now()
strnow = now.strftime('%Y-%m-%d %H:%M:%S')
print("now:",strnow)
# First next run time
period = timedelta(days=day, hours=hour, minutes=min, seconds=second)
next_time = now + period
strnext_time = next_time.strftime('%Y-%m-%d %H:%M:%S')
print("next run:",strnext_time)
i=12
while(i<31):
# Get system current time
iter_now = datetime.now()
iter_now_time = iter_now.strftime('%Y-%m-%d %H:%M:%S')
if str(iter_now_time) == str(strnext_time):
i=i+1
# Get every start work time
print("start work: %s" % iter_now_time)
# Call task func
func(i)
print("task done.")
# Get next iteration time
iter_time = iter_now + period
strnext_time = iter_time.strftime('%Y-%m-%d %H:%M:%S')
print("next_iter: %s" % strnext_time)
# Continue next iteration
continuerunTask(work, min=0.5)
1、日志分布情况：
机子slave1上有个日志文件：/home/hadoop/LogModel/source1
机子slave2上有个日志文件：/home/hadoop/LogModel/source2
2、日志汇总：
机子hadoop上在HDFS中有个日志汇总文件：/LogModel/source
3、具体实现：
对于slave1主机：
#agent1
a1.sources=sc1
a1.sinks=sk1
a1.channels=ch1
#source1
a1.sources.sc1.type=spooldir
a1.sources.sc1.spoolDir=/home/hadoop/LogModel/source1

#sink1
a1.sinks.sk1.type=avro
a1.sinks.sk1.hostname=hadoop
a1.sinks.sk1.port=23004
a1.sinks.sk1.channel=ch1:#agent2
a2.sources=sc2
a2.sinks=sk2

a3.sinks.sk2.hdfs.rollSize=0
a3.sinks.sk2.hdfs.rollCount=0在HDFS中得到文件夹：
/LogModel/source/
五、利用java封装日志信息：
1、分析日志格式：每行以空格隔开，包含11段：日期、时间、客户端主机IP、服务器IP、服务器端口、请求、源页面、状态、浏览器和操作系统版本
2004-12-13 00:02:37 219.137.244.90 - 211.66.184.35 80 GET /news/newshtml/schoolNews/20041210171434.asp - 200 Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+MyIE2)
2004-12-13 00:00:45 172.16.96.22 - 211.66.184.35 80 GET /all.css - 304 Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1)
2004-12-18 23:58:47 172.16.96.14 - 211.66.184.35 80 GET /images/index_r2_c7.jpg - 304 Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.0)
2、分析保留主要字段：
日期、时间、客户端主机IP、服务器IP、源页面、状态、浏览器版本、操作系统版本
3、分装日志对象：
public class Log {
private String date;
private String time;
private String client_IP;
private String server_IP;
private String orignHtml;
private String status;
private String Btype;
//构造函数
public Log()
{}
public Log(String log)
{
String[]logs=log.split(" ");
if(logs.length>10)
{
if(logs[0].length()>=10)
{
this.date=logs[0].substring(logs[0].length()-10);
}
this.time=logs[1];
this.client_IP=logs[2];
this.server_IP=logs[4];
this.orignHtml=logs[7];
this.status=logs[9];
this.Btype=logs[10];
}
}
//set、get函数
public String getBtype() {
return Btype;
}
public void setBtype(String btype) {
Btype = btype;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public String getTime() {
return time;
}
public void setTime(String time) {
this.time = time;
}
public String getClient_IP() {
return client_IP;
}
public void setClient_IP(String client_IP) {
this.client_IP = client_IP;
}
public String getServer_IP() {
return server_IP;
}
public void setServer_IP(String server_IP) {
this.server_IP = server_IP;
}
public String getOrignHtml() {
return orignHtml;
}
public void setOrignHtml(String orignHtml) {
this.orignHtml = orignHtml;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
}public class LogFormat {
public static class LogMap extends Mapper<Object, Text, NullWritable, Text>{
public void map(Object key, Text value, Context context) throws IOException, InterruptedException {
//获取一行日志
if(!value.toString().startsWith("#")&&value.toString()!=null&&value.toString().length()>60)
{
Log log=new Log(value.toString());
//注意如何处理过滤掉不合格的数据
if(log.getDate()!=null&&log.getTime()!=null&&!log.getTime().equals("date")&&!log.getTime().equals("time")&&log.getDate().contains("-")&&log.getTime().contains(":"))
{
//构造格式化日志
String val=log.getDate()+"\t"+log.getTime()+"\t"+log.getClient_IP()+"\t"+log.getServer_IP()+"\t"+log.getOrignHtml()+"\t"+log.getStatus()+"\t"+log.getBtype();
//写出
context.write(NullWritable.get(),new Text(val));
}
}
}
}
public static void main(String[] args) throws Exception {
Configuration conf = new Configuration();
String[] otherArgs = new GenericOptionsParser(conf, args).getRemainingArgs();
if (otherArgs.length != 2) {
System.err.println("Usage: LogFormat <in> <out>");
System.exit(2);
}
Job job = Job.getInstance(conf, "LogFormat");
job.setJarByClass(LogFormat.class);
job.setMapperClass(LogMap.class);
job.setOutputKeyClass(NullWritable.class);
job.setOutputValueClass(Text.class);
FileInputFormat.addInputPath(job, new Path(otherArgs[0]));
FileOutputFormat.setOutputPath(job,new Path(otherArgs[1]));
job.waitForCompletion(true);
System.out.println("Job is successful?:"+(job.isSuccessful() ? "shi": "no"));
}
}1、MySQL配置：【尤其是远程访问】
MySQL安装在slave1机子上，建立xuchao用户，赋予所有的权限：
A、修改/etc/mysql/my.cnf文件，把bind.adress=127.0.0.1改为 0.0.0.0;
B、grant all privileges on *.* to 'xuchao'@'%' identified by '123456'; FLUSH PRIVILEGES;
C、重新启动mysql服务：/etc/init.d/mysql start
2、在MySQL中建立一张表：
create table Log(date char(11),time char(9),client_IP char(15),server_IP char(15),orignHtml char(100),status char(4),Btype char(120))
sqoop export --connect jdbc:mysql://slave1:3306/Log --username xuchao --password 123456 --table Log --export-dir /output/part-r-00000
--input-fields-terminated-by '\t' --input-null-string '\\N' --input-null-non-string '\\N'
import os
import sys
from datetime import date, time, datetime, timedelta
from stat import *
def MySQLBackup():
User = 'xuchao'
Passwd = '123456'
Mysqlcommand = '/usr/bin/mysqldump'
Gzipcommand = '/bin/gzip'
Mysqldata = ['Log','Log']
Tobackup = '/home/hadoop/LogModel/mysqlBackup/'
for DB in Mysqldata:
now = datetime.now()
Backfile = Tobackup + DB + '-' + now.strftime('%H-%M-%S') + '.sql'
Gzfile = Backfile +'.gz'
if os.path.isfile(Gzfile):
print(Gzfile + " is already backup")
else:
Back_command = Mysqlcommand + '-h slave1 -u' + User + ' -p' + Passwd + ' -P3306 ' + DB + ' > ' + Backfile
if os.system(Back_command)==0:
print('Successful backup to', DB + ' to ' + Backfile)
else:
print('Backup FAILED')
Gzip_command = Gzipcommand + ' ' + Backfile
if os.system(Gzip_command)==0:
print('Successful Gzip to',Gzfile)
else:
print('Gzip FAILED')
Scp_command1='scp -r '+Tobackup+' hadoop@hadoop:~/LogModel/'
Scp_command2='scp -r '+Tobackup+' hadoop@slave2:~/LogModel/'
if os.system(Scp_command1)==0:
print('Successful backup to', DB + ' to hadoop')
else:
print('Backup To hadoop FAILED')
if os.system(Scp_command2)==0:
print('Successful backup to', DB + ' to slave2')
else:
print('Backup To slave2 FAILED')
def runTask(func, day=0, hour=0, min=0, second=0):
# Init time
now = datetime.now()
strnow = now.strftime('%Y-%m-%d %H:%M:%S')
print("now:",strnow)
# First next run time
period = timedelta(days=day, hours=hour, minutes=min, seconds=second)
next_time = now + period
strnext_time = next_time.strftime('%Y-%m-%d %H:%M:%S')
print("next run:",strnext_time)
while True:
# Get system current time
iter_now = datetime.now()
iter_now_time = iter_now.strftime('%Y-%m-%d %H:%M:%S')
if str(iter_now_time) == str(strnext_time):
# Get every start work time
print("start work: %s" % iter_now_time)
# Call task func
func()
print("task done.")
# Get next iteration time
iter_time = iter_now + period
strnext_time = iter_time.strftime('%Y-%m-%d %H:%M:%S')
print("next_iter: %s" % strnext_time)
# Continue next iteration
continue
runTask(MySQLBackup, hour=10)1、配置MySQL作为Hive的远程元数据库：
在mysql中创建一个用户：
create user 'hive' identified by '123456';
grant all privileges on *.* to 'hive'@'%' with grant option;
FLUSH PRIVILEGES; <property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://slave1:3306/hive?createDatabaseIfNotExist=true</value>
<description>JDBC connect string for a JDBC metastore</description>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>123456</value>
<description>password to use against metastore database</description>
</property>
2、从HDFS中直接导入数据到Hive表中：
创建空表：
create table Log(dat string,tim string,client_IP string,server_IP string,status string,Btype string) row format delimited fields terminated by '\t';
load data inpath '/output/part-r-00000' overwrite into table Log;十、利用SQL进行简单的数据统计

200 94975
206 114
207 59
302 144
304 128762
403 39
404 4486
