基于主机的管理一般需要收集服务器的日志信息用于及时发现错误,处理故障。

搭建linux下的集中日志服务器的程序一般可以用syslog,rsyslog,syslog-ng,还有scribe和fluentd等。

基本每一种方式都是服务器端和客户端的模式。

一般syslog,syslog-ng,rsyslog用于收集系统日志,scribe和fluentd用于收集业务日志,rsyslog和syslog-ng也可以收集业务日志,并可定制和过滤、筛选。

LogAnalyzer和LogZilla是分析系统日志,并用web界面展示的的工具,一般只用在syslog,syslog-ng,rsyslog日志系统中。

如下是基于Centos5的rsyslog+mysql+phplogcon的安装,安装前确认安装有EPEL源。

安装rsyslog以及rsyslog-mysql接口支持

yum install rsyslog rsyslog-mysql

安装数据库以及web程序

yum install mysql-server
yum install httpd php php-mysyql php-gd
service mysqld status || service mysqld start

创建rsyslog写入数据需要的库文件,路径可能根据版本有所不同
mysql < /usr/share/doc/rsyslog-mysql-2.0.8/createDB.sql 创建账户和密码(确保一致/etc/rsyslog.conf and /path/top/phplogcon/config.php )

mysql&gt; grant all on Syslog.* to syslog@localhost identified by 'mypass';
mysql&gt; flush privileges ;

vi /etc/rsyslog.conf
# Log to Mysql Settings
$ModLoad ommysql
*.* :ommysql:localhost,Syslog,syslog,phplogcon
#Standard Redhat syslog settings
*.info;mail.none;authpriv.none;cron.none /var/log/messages
authpriv.* /var/log/secure
mail.* -/var/log/maillog
cron.* /var/log/cron
*.emerg *
uucp,news.crit /var/log/spooler
local7.* /var/log/boot.log

启动rsyslog:

service syslog stop
service rsyslog start

如果有如下报错信息
Feb 23 23:43:30 mon rsyslogd:could not load module ‘/usr/lib/rsyslog/ommysql’, dlopen: /usr/lib/rsyslog/ommysql: cannot open shared object file: No such file or directory

请尝试软连接
fix fast with:
ln -s /usr/lib/rsyslog/ommysql.so /usr/lib/rsyslog/ommysql

开机启动rsyslog,并关闭syslog的开机启动:
chkconfig syslog off
chkconfig rsyslog on

开启接收远程信息:
edit /etc/sysconfig/rsyslog with option -r:
修改成:SYSLOGD_OPTIONS=”-m 0 -r”
默认开启UDP 514端口,请确保防火墙没有阻止。

以下是PHPLOGCON的安装
到网址下载最新版本,http://www.phplogcon.org/
新版本已更名为LogAnalyzer

安装如下方式安装
tar -zxvf phplogcon-2.8.1.tar.gz
cd phplogcon-2.8.1
mkdir /var/www/html/syslog
cp -a src/* /var/www/html/syslog
cd /var/www/html/syslog
chmod 666 config.php

打开浏览器输入: http://yourserver/syslog/
按照提示操作
安装好后,请做如下操作,以防止被修改。
chmod 644 config.php

客户端发送日志

以Centos为例,不需要安装其他日志程序,直接修改/etc/syslog.conf,在最后一行下面加入:

/var/log/messages @rsyslog_IP

保存,重启service syslog restart

查看phplogcon界面是否有客户端的日志出现。

It was in the 1925 Baptist Faith & Message:“He was created into a state of holiness under the law of his Maker, but, throughthe temptation of Satan, he transgressed the command of God and fell from hisoriginal holiness and righteousness; whereby his posterity inherit a nature corruptand in bondage to sin, and are under condemnation, and as soon as they are capableof moral action, become actual trsssgreanors.”We are under condemnation when born, according to that.

  2. 首先谢谢你的解答,看过你提供的链接后,有很多帮助,只是我选择放弃了继续研究通过rsyslog收集业务日志,取而代之的是我想使用logstash,现在正在研究中。。因为一直忙,忘了回来答谢,楼主见谅

  3. 最近在开发并使用rsyslog,我记录的日志有点长,但是rsyslog有长度限制被截取了,如何让rsyslog记录长日志到mysql

    1. 这个你大概要定义入库的模板。
      Module Parameters

      template
      The default template to use. This template is used when no template is explicitely specified in the action() statement.
      template
      Template to use when submitting messages.

      Note rsyslog contains a canned default template to write to the MySQL database. It works on the MonitorWare schema. This template is:
      $template tpl,”insert into SystemEvents (Message, Facility, FromHost, Priority, DeviceReportedTime, ReceivedAt, InfoUnitID, SysLogTag) values (‘%msg%’, %syslogfacility%, ‘%HOSTNAME%’, %syslogpriority%, ‘%timereported:::date-mysql%’, ‘%timegenerated:::date-mysql%’, %iut%, ‘%syslogtag%’)”,SQL

  4. 我依然在考虑rsyslog发送tomcat日志!

    今天配置是成功了,也可以正常发送但是有一个问题。
    $InputFileName 这个值貌似只能写绝对文本路径 !但是都知道tomcat访问日志是每天一个文件的!如同这样!
    localhost_access_log.2016-06-22.txt
    localhost_access_log.2016-06-21.txt
    localhost_access_log.2016-06-20.txt
    不知道各位是否有好的办法
