大数据应用日志采集之Scribe 安装配置指南

1.概述

Scribe是Facebook开源的日志收集系统,在Facebook内部已经得到大量的应用。它能从各种日志源收集日志,存储到一个*存储系统上,便于进行集中统计分析处理。它为日志的”分布式收集,统一处理”提供了一个可扩展的,高容错的方案。scribe代码很简单,但是安装配置却很复杂,本文记录了作者实际的一次安装的过程,感觉真是不一般的琐碎,另外Scribe开源社区的版本已经是几年前的版本了,最新的维护信息一致没有看到,HDFS和Thrift的版本使用的都是比较旧的版本,考虑另开一个分支,升级一下Scribe,看到时候有没有时间了。

2.Scribe 安装

Scribe 依赖于多个环境,有pthyon,boost,thirft,libevent,openssl等。在编译的时候还有一些编译错误需要进行修正,安装的和准备如下。

2.1 环境准备

  1.安装编译环境

#yum install gcc-c++ libevent libevent-devel automake autoconf m4 bison zlib zlib-devel bzip2 bzip2-devel flex pkgconfig python python-devel ruby ruby-devel mono-devel libxml2 libxml2-devel ant openssl-devel

  2.安装boost环境:最低版本1.36

        #wget http://nchc.dl.sourceforge.net/project/boost/boost/1.45.0/boost_1_45_0.tar.gz

        #tar zxvf boost_1_45_0.tar.gz

        #cd boost_1_45_0

        #./bootstrap.sh 

        #./bjam

      #./bjam --s HAVE_ICU=1 --prefix=/usr/local/boost --includedir=/usr/local/boost/include  --libdir=/usr/local/boost/lib

       #./bjam install –prefix=/usr/local/boost

       #echo "/usr/local/boost/lib" >> /etc/ld.so.conf

       #echo /usr/local/boost/include >> /etc/ld.so.conf

     #ldconfig

  3. 安装thrift环境

  #wget https://dist.apache.org/repos/dist/release/thrift/0.9.0/thrift-0.9.0.tar.gz

      #tar xzvf thrift-0.9.0.tar.gz

      #./configure --prefix=/usr/local/thrift --with-boost=/usr/local/boost --with-java=no  --with-erlang=no  --with-perl=no  --with-php=no  --with-ruby=no

 备注:如果提示找不到libcrpty增加openssl路径

 ./configure --prefix=/usr/local/thrift --with-boost=/usr/local/boost --with-java=no  --with-erlang=no --with-perl=no --with-php=no  --with-  ruby=no CPPFLAGS="-I/usr/local/openssl/include" LDFLAGS="-ldl -L/usr/local/openssl/lib"

 修改文件:

  Thrift/lib/ src/thrift/Thrift.cpp 增加头文件:#include<stdlib.h>     

同时修改config.h文件,注释掉:

/* Define to rpl_malloc if the replacement function should be used. */

//modby zhangzl++:

//#define malloc rpl_malloc

//--

/* Define to rpl_realloc if the replacement function should be used. */

//modby zhangzl++:

//#define realloc rpl_realloc

//--

#make

#make install

# echo "/usr/local/thrift/lib" >> /etc/ld.so.conf

#ldconfig

#cd contrib.

  4.安装fb303

#cd fb303

#./bootstrap.sh

#./configure --prefix=/usr/local/thrift/fb303 --with-boost=/usr/local/boost/ --with-thriftpath=/usr/local/thrift

#make

//注意修改观察生成的Makefile关于头文件和库文件路径的信息是否正确,如果正确则可以直接编译。

  #make install  

4.安装scribe

https://github.com/facebook/scribe下载zip包。

#unzip scribe-master.zip

#cd scribe-master

# export BOOST_ROOT=/usr/local/boost

#export LD_LIBRARY_PATH=/usr/local/thrift/lib:/usr/lib:/usr/local/lib:/usr/local/boost/lib:/usr/local/thrift/fb303/lib

#./bootstrap.sh  --with-boost=/usr/local/boost --with-boost-filesystem=boost_filesystem

遇到问题:

checking whether the Boost::System library is available… yes

checking whether the Boost::Filesystem library is available… yes

configure: error: Could not link against  !

解决办法,在configure 后加一个参数 --with-boost-filesystem=boost_filesystem

 

#./configure --prefix=/usr/local/scribe --with-boost=/usr/local/boost --with-thriftpath=/usr/local/thrift  --with-fb303path=/usr/local/thrift/fb303 --with-boost-filesystem=boost_filesystem

#make

遇到问题:

  1. thrift/server/TNonblockingServer.h:40:19: error: event.h: No such file or directory
  2. 安装Libevent

#tar zxvf libevent-2.0.18-stable.tar.gz
#cd libevent-2.0.18-stable
#./configure –prefix=/usr/local/libevent
#make
#make install

  3.安装libevent-devel

yum install libevent-devel

error: there are no arguments to 'htons' that depend on a template parameter, so a declaration of 'htons' must be available

需要自己修改一下文件:

vim /usr/local/thrift/include/thrift/protocol/TBinaryProtocol.tcc

在首行添加头文件引用: #include <arpa/inet.h>

#echo /usr/local/libevent/include>> /etc/ld.so.conf

#ldconfig

#make install

2.2 测试

#cp example/example1.conf  /tmp

#/usr/local/scribe/bin/scribed /tmp/example1.conf

进行测试。

如果失败,根据提示信息,进行相应修改。

我启动时出现下面的错误:

./scribed: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory

解决办法是find这个库文件libevent-2.0.so.5,拷贝到/usr/lib64目录下。

启动成功后,出现下面的界面:

3.Scribe配置   

Scribe 的配置解析见http://my.oschina.net/guol/blog/110258

测试通过的server端和client端的配置文件如下:

  1. Server.conf

port=1463

max_msg_per_second=100000000

max_queue_size=10000000

check_interval=1

new_thread_per_category=true      

<store>

category=squid

type=file

file_path=/tmp/test/logcollect/

base_filename=21vianet__squid_access_all_

rotate_period=daily

rotate_hour=0

rotate_minute=0

max_size=1610612736

add_newlines=0

</store>

  1. Client.conf

port=1464

max_msg_per_second=2000000

max_queue_size=1000000

check_interval=1

new_thread_per_category=true      

 

<store>

category=default

type=buffer

target_write_size=20480

max_write_interval=1

buffer_send_rate=2

retry_interval=30

retry_interval_range=10

 

<primary>

type=network

#remote_host=218.93.205.106

remote_host=192.168.11.95

remote_port=1463

</primary>

 

<secondary>

type=file

fs_type=std

write_meta=no

file_path=/tmp/test/scribed

base_filename=accesslog

max_size=100000000

add_newlines=0

</secondary>

</store>

注意:

 在server端接收的日志,将以文件的方式来记录log,这个文件不能删除,它是个软连接。需要先copy过去,再调用touch命令将文件清空。
