====================再看一例=======================
以上配置的是将公司防火墙的日志打到rsyslog里。现在有这么一个需求：
公司IDC的另外两台服务器172.19.10.24和172.19.10.25上部署了gitlab、nexus、jenkins、jira和wiki，上面的权限设置的比较杂，很多人都有登录需求。现在需要将登录到这两台服务器上的用户的所有操作过程记录下来，记录达到rsyslog日志里，相当于做用户操作记录的审计工作。
配置如下（结合上面的安装配置）（服务端的ip是172.19.16.21）：
1）rsyslog服务端配置 （相比于上面的配置，这里去掉了AllowedSender的来源ip的白名单限制。即允许接收所有机器的日志；上面的防火墙日志还是能继续收集）
[root@zabbix ~]# cat /etc/rsyslog.conf|grep -v "#"|grep -v "^$"
$ModLoad imudp
$UDPServerRun 514
$WorkDirectory /var/lib/rsyslog
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$template Remote,"/data/fw_logs/%fromhost-ip%/%fromhost-ip%_%$YEAR%-%$MONTH%-%$DAY%.log"
:fromhost-ip, !isequal, "127.0.0.1" ?Remote
$IncludeConfig /etc/rsyslog.d/*.conf
*.info;mail.none;authpriv.none;cron.none /var/log/messages
authpriv.* /var/log/secure
mail.* -/var/log/maillog
cron.* /var/log/cron
*.emerg *
uucp,news.crit /var/log/spooler
local7.* /var/log/boot.log
local5.* /var/log/history.log
[root@zabbix ~]# /etc/init.d/rsyslog restart
2）在172.19.10.24上的配置
[root@gitlab ~]# cat /etc/rsyslog.conf|grep -v "#"|grep -v "^$"
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf
*.info;mail.none;authpriv.none;cron.none /var/log/messages
authpriv.* /var/log/secure
mail.* -/var/log/maillog
cron.* /var/log/cron
*.emerg *
uucp,news.crit /var/log/spooler
local7.* /var/log/boot.log
local5.* @172.19.16.21
[root@gitlab ~]# /etc/init.d/rsyslog restart
[root@gitlab ~]# cat /etc/profile #在该文件的底部添加下面内容
.......
export HISTTIMEFORMAT
export PROMPT_COMMAND='{ command=$(history 1 | { read x y; echo $y; }); logger -p local5.notice -t bash -i "user=$USER,ppid=$PPID,from=$SSH_CLIENT,pwd=$PWD,command:$command"; }'
3）在另一台172.19.10.25上做类似配置配置
[root@nexus ~]# cat /etc/rsyslog.conf |grep -v "#"|grep -v "^$"
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf
*.info;mail.none;authpriv.none;cron.none /var/log/messages
authpriv.* /var/log/secure
mail.* -/var/log/maillog
cron.* /var/log/cron
*.emerg *
uucp,news.crit /var/log/spooler
local7.* /var/log/boot.log
local5.* @172.19.16.21
[root@nexus ~]# /etc/init.d/rsyslog restart
[root@nexus ~]# cat /etc/profile
.......
export HISTTIMEFORMAT
export PROMPT_COMMAND='{ command=$(history 1 | { read x y; echo $y; }); logger -p local5.notice -t bash -i "user=$USER,ppid=$PPID,from=$SSH_CLIENT,pwd=$PWD,command:$command"; }'
4）过一段时间，发现在rsyslog服务端的日志目录/data/fw_logs下面已经有收集到的日志了
[root@zabbix fw_logs]# pwd

[root@zabbix fw_logs]# cd
[root@zabbix ~]# cd /data/fw_logs/

.......
有上面日志可以看出，在172.19.10.24这台机器上的操作记录都被详细记录下来了。这样，就能清楚地知道登录到这台机器上的用户都做了些什么了.......
