将WEB日志导入到数据库中
- 1. mysql
- 2. Apache Pipe
- 3. Log format
- 4. 日志导入到 MongoDB
1. mysql
将WEB服务器日志通过管道处理然后写入数据库
处理程序源码
$ vim match.d
import std.regex;
import std.stdio;
import std.string;
import std.array;
void main()
{
// nginx
//auto r = regex(`^(\S+) (\S+) (\S+) \[(.+)\] "([^"]+)" ([0-9]{3}) ([0-9]+) "([^"]+)" "([^"]+)" "([^"]+)"`);
// apache2
auto r = regex(`^(\S+) (\S+) (\S+) \[(.+)\] "([^"]+)" ([0-9]{3}) ([0-9]+) "([^"]+)" "([^"]+)"`);
foreach(line; stdin.byLine)
{
foreach(m; match(line, r)){
//writeln(m.hit);
auto c = m.captures;
c.popFront();
//writeln(c);
auto value = join(c, "\",\"");
auto sql = format("insert into log(remote_addr,unknow,remote_user,time_local,request,status,body_bytes_sent,http_referer,http_user_agent,http_x_forwarded_for) value(\"%s\");", value );
writeln(sql);
}
}
}
编译
$ dmd match.d $ strip match $ ls match match.d match.o
简单用法
$ cat access.log | ./match
高级用法
$ cat access.log | match | mysql -hlocalhost -ulog -p123456 logging
实时处理日志，首先创建一个管道，寻该日志文件写入管道中。
cat 管道名 | match | mysql -hlocalhost -ulog -p123456 logging
这样就可以实现实时日志插入。
提示
上面程序稍加修改即可实现Hbase, Hypertable 本版
2. Apache Pipe
Apache 日志管道过滤 CustomLog "| /srv/match >> /tmp/access.log" combined
<VirtualHost *:80>
ServerAdmin webmaster@localhost

DocumentRoot /www
<Directory />
Options FollowSymLinks

经过管道转换过的日志效果
$ tail /tmp/access.log
insert into log(remote_addr,unknow,remote_user,time_local,request,status,body_bytes_sent,http_referer,http_user_agent,http_x_forwarded_for) value("192.168.6.30","-","-","21/Mar/2013:16:11:00 +0800","GET / HTTP/1.1","304","208","-","Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.172 Safari/537.22");
insert into log(remote_addr,unknow,remote_user,time_local,request,status,body_bytes_sent,http_referer,http_user_agent,http_x_forwarded_for) value("192.168.6.30","-","-","21/Mar/2013:16:11:00 +0800","GET /favicon.ico HTTP/1.1","404","501","-","Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.172 Safari/537.22");
insert into log(remote_addr,unknow,remote_user,time_local,request,status,body_bytes_sent,http_referer,http_user_agent,http_x_forwarded_for) value("192.168.6.30","-","-","21/Mar/2013:16:11:00 +0800","GET / HTTP/1.1","304","208","-","Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.172 Safari/537.22");
3. Log format
通过定义LogFormat可以直接输出SQL形式的日志
Apache
LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined
LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %O" common
LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent
Nginx
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
但对于系统管理员使用grep,awk,sed,sort,uniq分析时造成一定的麻烦。所以我建议仍然采用正则分解
4. 日志导入到 MongoDB
# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm # yum install mongodb
D语言日志处理程序
import std.regex;
//import std.range;
import std.stdio;
import std.string;
import std.array;
void main()
{
// nginx
auto r = regex(`^(\S+) (\S+) (\S+) \[(.+)\] "([^"]+)" ([0-9]{3}) ([0-9]+) "([^"]+)" "([^"]+)" "([^"]+)"`);
// apache2
//auto r = regex(`^(\S+) (\S+) (\S+) \[(.+)\] "([^"]+)" ([0-9]{3}) ([0-9]+) "([^"]+)" "([^"]+)"`);
foreach(line; stdin.byLine)
{
//writeln(line);
//auto m = match(line, r);
foreach(m; match(line, r)){
//writeln(m.hit);
auto c = m.captures;
c.popFront();
//writeln(c);
/*
SQL
auto value = join(c, "\",\"");
auto sql = format("insert into log(remote_addr,unknow,remote_user,time_local,request,status,body_bytes_sent,http_referer,http_user_agent,http_x_forwarded_for) value(\"%s\");", value );
writeln(sql);
*/
// MongoDB
string bson = format("db.logging.access.save({
'remote_addr': '%s',
'remote_user': '%s',
'time_local': '%s',
'request': '%s',
'status': '%s',
'body_bytes_sent':'%s',
'http_referer': '%s',
'http_user_agent': '%s',
'http_x_forwarded_for': '%s'
})",
c[0],c[2],c[3],c[4],c[5],c[6],c[7],c[8],c[9]
);
writeln(bson);
}
}
}
变异处理程序
dmd mlog.d
用法
cat /var/log/nginx/access.log | mlog | mongo 192.169.0.5/logging -uxxx -pxxx
处理压错过的日志
# zcat /var/log/nginx/*.access.log-*.gz | /srv/weblog | mongo 192.168.6.1/logging -uneo -pchen
