日志:历史日志

  历史事件:

    时间记录,事件的关键性程度,loglevel  

  系统日志服务:

    syslogd,守护进程

      syslogd:system

      klogd:kernel

     rsyslog:

      syslogd

      klogd

      多线程:

      UDP,TCP,SSL,TLS,

      Mysql,PGSQL

      强大的过滤器,可实现过滤日志信息中的任何部分;

      自定义输出格式;

  日志收集方:

 priority:

  debug,info,notice,warn(warning),err(error),crit(critical),alert,emerg(panic)

  调试-信息级别-引起注意-警告-产生错误-蓝色警报-橙色警报-要挂了。

  指定级别:

    *:表示所以级别

    none:没用级别

    priority:此级别及更高级别的日志信息;

  [root@localhost ~]# rpm -ql rsyslog    

    /etc/rsyslog.conf   主配置文件

    rsyslogd      主程序;

    /etc/rc.d/init.d/rsyslog  服务脚本;

root@localhost ~]# vim /etc/rsyslog.conf  

# rsyslog v5 configuration file

# For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html
# If you experience problems, see http://www.rsyslog.com/doc/troubleshoot.html

#### MODULES #### 

$ModLoad imuxsock # provides support for local system logging (e.g. via logger command) //支持本地日志收集的模块
$ModLoad imklog   # provides kernel logging support (previously done by rklogd) //支持本地内核日志收集的模块
#$ModLoad immark  # provides --MARK-- message capability

# Provides UDP syslog reception
#$ModLoad imudp
#$UDPServerRun 514

# Provides TCP syslog reception
#$ModLoad imtcp
#$InputTCPServerRun 514


#### GLOBAL DIRECTIVES #### 全局参数指定

# Use default timestamp format
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

# File syncing capability is disabled by default. This feature is usually not required,
# not useful and an extreme performance hit
#$ActionFileEnableSync on

# Include all config files in /etc/rsyslog.d/
$IncludeConfig /etc/rsyslog.d/*.conf


#### RULES ####

# Log all kernel messages to the console.
# Logging much else clutters up the screen.
#kern.*                                                 /dev/console  //

# Log anything (except mail) of level info or higher.
# Don‘t log private authentication messages!
*.info;mail.none;authpriv.none;cron.none                /var/log/messages   //

 

# The authpriv file has restricted access.
authpriv.*                                              /var/log/secure

# Log all the mail messages in one place.
mail.*                                                  -/var/log/maillog    //-号表示异步写入;


# Log cron stuff
cron.*                                                  /var/log/cron

# Everybody gets emergency messages
*.emerg                                                 *  //通知所有用户在线的用户系统要挂了

# Save news errors of level crit and higher in a special file.
uucp,news.crit                                          /var/log/spooler  

# Save boot messages also to boot.log
local7.*                                                /var/log/boot.log  //自定义日志


# ### begin forwarding rule ###
# The statement between the begin ... end define a SINGLE forwarding
# rule. They belong together, do NOT split them. If you create multiple
# forwarding rules, duplicate the whole block!
# Remote Logging (we use TCP for reliable delivery)
#
# An on-disk queue is created for this action. If the remote host is
# down, messages are spooled to disk and sent when it is up again.
#$WorkDirectory /var/lib/rsyslog # where to place spool files
#$ActionQueueFileName fwdRule1 # unique name prefix for spool files
#$ActionQueueMaxDiskSpace 1g   # 1gb space limit (use as much as possible)
#$ActionQueueSaveOnShutdown on # save messages to disk on shutdown
#$ActionQueueType LinkedList   # run asynchronously
#$ActionResumeRetryCount -1    # infinite retries if host is down
# remote host is: name/ip:port, e.g. 192.168.0.1:514, port optional
#*.* @@remote-host:514
# ### end of the forwarding rule ###

# A template to for higher precision timestamps + severity logging
$template SpiceTmpl,"%TIMESTAMP%.%TIMESTAMP:::date-subseconds% %syslogtag% %syslogseverity-text%:%msg:::sp-if-no-1st-sp%%msg:::drop-last-lf%\n"

:programname, startswith, "spice-vdagent"       /var/log/spice-vdagent.log;SpiceTmpl
(END)

主服务器测试:

root@localhost ~]# vim /etc/ssh/sshd_config  

    添加:SyslogFacility local2

      service sshd reload

root@localhost ~]# vim /etc/rsyslog.conf

   local7.*  /var/log/boot.log 下添加如下:

   local2.*  /var/log/sshd.log

   重启服务:servicee rsyslog restart

  测试:只要复制下当前xshell会话即可,然后查看日志;

总结:

  文件记录的日志的格式:

    时间产生记录的日期时间      主机     进程(PID) :事件内容

  有些日志记录二进制格式:/var/log/wtmp,/var/logbtmp  

    /var/log/wtmp :当前系统上成功登陆的日志;

      last 查看

    /var/log/btmp:当前系统上失败的登陆尝试;

      lastb

    lastlog   查看哪些用户登陆过系统,

      mail                                       **Never logged in** 表示从来没用登陆过系统;

一:rsyslog服务器:

1,主服务器:root@localhost ~]# vim /etc/rsyslog.conf

  # Provides UDP syslog reception
  $ModLoad imudp  去掉#号
  $UDPServerRun 514   去掉#号

  # Provides TCP syslog reception
  $ModLoad imtcp    去掉#号
  $InputTCPServerRun 514    去掉#号

  service rsyslog restart

  netstat -tunl

3:主服务器查看日志:

  tail /var/log/messages

2,从服务器:

  主服务器:root@localhost ~]# vim /etc/rsyslog.conf

  *.info;mail.none;authpriv.none;cron.none  @172.16.100.6  //把从服务器的日志传输给主日志服务器;

  service rsyslog restart

  yum -y install vsftpd

二:  配置下rsyslog如何记录到mysql服务中;

 1:从服务安装mysql;

 查看包:   rpm -q mariadb

    安装: [root@localhost ~]# yum -y install mariadb-server

 启动: [root@localhost ~]# systemctl start mariadb.service

 查看监听:ss -tnlp 

 进入mysql数据库: [root@localhost ~]# mysql -uroot -p  直接回车,默认密码为空;

      mariaDB [(none)]> use mysql;

      MariaDB [mysql]> update user set password=password(‘password‘) where user=‘root‘;

     MariaDB [(none)]> GRANT ALL ON Syslog.* TO ‘syslog‘@‘192.168.%.%‘ IDENTIFIED BY ‘syslogpass‘;

     MariaDB [mysql]> flush privileges;

   MariaDB [mysql]> quit

  root@localhost ~]# vim /etc/my.cnf

    [mysqld]

     skip_name_resolve = on
     innodb_file_per_table = on

   [root@localhost ~]# systemctl restart mariadb.service

   [root@localhost ~]# ss -tnl

  测试:

  [root@localhost ~]# mysql -usyslog -psyslogpass -h 192.168.214.140
  Welcome to the MariaDB monitor.  Commands end with ; or \g.

  | information_schema |
  | test               |

  MariaDB [(none)]>

4:验证

  [root@localhost ~]# mysql -usyslog -psyslogpass -h 192.168.214.140
  Welcome to the MariaDB monitor.  Commands end with ; or \g.
  Your MariaDB connection id is 5
  Server version: 5.5.56-MariaDB MariaDB Server

  Copyright (c) 2000, 2017, Oracle, MariaDB Corporation Ab and others.

  Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.  MariaDB [(none)]> show databases;
  +--------------------+
  | Database           |
  +--------------------+
  | information_schema |
  | Syslog             |
  | test                 |
  +--------------------+
  3 rows in set (0.00 sec)
  MariaDB [(none)]> use Syslog
  Reading table information for completion of table and column names
  You can turn off this feature to get a quicker startup with -A

  Database changed
  MariaDB [Syslog]> show tables;
  +------------------------+
  | Tables_in_Syslog       |
  +------------------------+
  | SystemEvents           |
  | SystemEventsProperties |
  +------------------------+
  2 rows in set (0.00 sec)

6:查看日志

  MariaDB [Syslog]> show tables;
  
+------------------------+
  | Tables_in_Syslog       |
  +------------------------+
  | SystemEvents           |
  | SystemEventsProperties |
  +------------------------+
  2 rows in set (0.00 sec)

  MariaDB [Syslog]>
  MariaDB [Syslog]> show tables;
  +------------------------+
  | Tables_in_Syslog       |
  +------------------------+
  | SystemEvents           |
  | SystemEventsProperties |
  +------------------------+
  2 rows in set (0.00 sec)

  MariaDB [Syslog]> select * from SystemEvents\G;

  

2:主服务器端想要rsyslog日志存储到mysql服务器中,使用 yum list all rsyslog*,有一个rsyslog-mysql的程序包,安装即可。

  yum -y install rsyslog-mysql

  [root@localhost log]# rpm -ql rsyslog-mysql

    /lib64/rsyslog/ommysql.so
    /usr/share/doc/rsyslog-mysql-5.8.10
    /usr/share/doc/rsyslog-mysql-5.8.10/createDB.sql

 3:[root@localhost log]# mysql -usyslog -h192.168.214.140 -p < /usr/share/doc/rsyslog-mysql-5.8.10/createDB.sql
  Enter password: syslogpass  //192.168.214.140是从服务器的IP地址
 5:[root@localhost log]# vim /etc/rsyslog.conf
     #### MODULES ####

      ModLoad ommysql  手动添加;

     #### RULES ####

      *.info;mail.none;authpriv.none;cron.none                :ommysql:192.168.214.140,Syslog,syslog,syslogpass

    service rsyslog restart

  记录日志:yum -y install vsftp

---------------------------------------------

主服务器:

  yum install httpd php php-mysql

  vim /var/www/html/index.php

    <?php
            $conn = mysql_connect(‘192.168.214.140‘,‘syslog‘,‘syslogpass‘);
          if  ($conn)
                  echo "OK";
          else
                  echo "Failure";
         ?>

  service httpd start

  网页测试:192.168.214.146  是否显示OK
