history linux 日志服务器_编译bash实现history的syslog日志记录

發(fā)布時(shí)間：2024/9/3 linux 23 豆豆
生活随笔 收集整理的這篇文章主要介紹了 history linux 日志服务器_编译bash实现history的syslog日志记录 小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

一、編譯BASH實(shí)現(xiàn)bash的syslog日志記錄功能

1. 本文將通過(guò)bash軟件實(shí)現(xiàn)history記錄到syslog日志的功能，并通過(guò)該方式可以實(shí)現(xiàn)實(shí)時(shí)的傳送到了遠(yuǎn)端的日志集中服務(wù)器上，可以實(shí)現(xiàn)操作目志的審計(jì)功能。

操作系統(tǒng)版本 : CentOS 6.5 x64

2. 安裝6.5對(duì)應(yīng)bash源碼包

#安裝報(bào)警告可以忽略。

warning: bash-4.1.2-15.el6_4.src.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY

warning: group mockbuild does not exist - using root

warning: user mockbuild does not exist - using root

warning: group mockbuild does not exist - using root

warning: user mockbuild does not exist - using root

[root@localhost soft]#

安裝完成后，會(huì)在當(dāng)前用戶(hù)主目錄下創(chuàng)建如下目錄結(jié)構(gòu)。

[root@localhost ~]# pwd

/root

# ls

anaconda-ks.cfg? bash-4.1.2-15.el6_4.src.rpm? install.log? install.log.syslog? rpmbuild? 公共的? 模板? 視頻? 圖片? 文檔? 下載? 音樂(lè)? 桌面

[root@localhost ~]# tree rpmbuild/

rpmbuild/

│?? └── dot-bashrc

└── SPECS

└── bash.spec

2 directories, 33 files

2. 進(jìn)入目錄中，解決bash-4.1源碼包目錄

[root@localhost ~]# cd /root/rpmbuild/SOURCES/

[root@localhost SOURCES]# tar zxvf bash-4.1.tar.gz

[root@localhost SOURCES]# cp -a bash-4.1 bash-4.1-orig

[root@localhost SOURCES]#

[root@localhost SOURCES]# cd bash-4.1

[root@localhost bash-4.1]#

3. 修改代碼段一

# vim config-top.h

#取消104行的注釋,并將下面代碼修改為如下內(nèi)容，默認(rèn)情況下日志記錄在/var/log/message文件中，這調(diào)整為local1.debug指定的文件中。

/* #define SYSLOG_HISTORY */

#if defined (SYSLOG_HISTORY)

# define SYSLOG_FACILITY LOG_LOCAL1

# define SYSLOG_LEVEL LOG_DEBUG

#endif

4. 修改代碼段二

# vim bashhist.c

#找到701行開(kāi)始的程序段

701 void

702 bash_syslog_history (line)

703????? const char *line;

704 {

705?? char trunc[SYSLOG_MAXLEN];

706

707?? if (strlen(line) < SYSLOG_MAXLEN)

708???? syslog (SYSLOG_FACILITY|SYSLOG_LEVEL, "HISTORY: PID=%d UID=%d %s", getpid(), current_user.uid, line);

709?? else

710???? {

711?????? strncpy (trunc, line, SYSLOG_MAXLEN);

712?????? trunc[SYSLOG_MAXLEN - 1] = '\0';

713?????? syslog (SYSLOG_FACILITY|SYSLOG_LEVEL, "HISTORY (TRUNCATED): PID=%d UID=%d %s", getpid(), current_user.uid, trunc);

714???? }

715 }

716 #endif

修改為如下內(nèi)容：

void

bash_syslog_history (line)

const char *line;

{

char trunc[SYSLOG_MAXLEN];

if (strlen(line) < SYSLOG_MAXLEN)

syslog (SYSLOG_FACILITY|SYSLOG_LEVEL, "HISTORY: PPID=%d PID=%d SID=%d UID=%d User=%s %s", getppid(), getpid(), getsid(getpid()), current_user.uid, current_user.user_name, line);

else

{

strncpy (trunc, line, SYSLOG_MAXLEN);

trunc[SYSLOG_MAXLEN - 1] = '\0';

syslog (SYSLOG_FACILITY|SYSLOG_LEVEL, "HISTORY (TRUNCATED): PPID=%d PID=%d SID=%d UID=%d User=%s %s", getppid(), getpid(), getsid(getpid()), current_user.uid, current_user.user_name, trunc);

}

}

5. 對(duì)比修改代碼

[root@localhost SOURCES]# diff -Npru bash-4.1-orig bash-4.1 > bash_history_syslog.patch

# cd ~/rpmbuild/SPECS/

# vim bash.spec

#加入兩行內(nèi)容，按如下格式如下，保存退出。

Patch119: bash_history_syslog.patch

…

%patch119 -p1 -b .history_syslog

…

6. 開(kāi)始編譯

[root@localhost SPECS]# rpmbuild -ba bash.spec

error: Failed build dependencies:

texinfo is needed by bash-4.1.2-15.el6.x86_64

再開(kāi)一個(gè)窗口安裝texinfo軟件包。

[root@localhost SPECS]# rpmbuild -ba bash.spec

[root@localhost SPECS]# cd? ~/rpmbuild/RPMS/x86_64/

7. 安裝bash rpm安裝包

[root@localhost ~]# cd? ~/rpmbuild/RPMS/x86_64/

[root@localhost x86_64]# ls

bash-4.1.2-15.el6.x86_64.rpm? bash-debuginfo-4.1.2-15.el6.x86_64.rpm? bash-doc-4.1.2-15.el6.x86_64.rpm

[root@localhost x86_64]#

[root@localhost x86_64]# rpm -Uvh --force bash-4.1.2-15.el6.x86_64.rpm

Preparing...??????????????? ########################################### [100%]

1:bash?????????????????? ########################################### [100%]

[root@localhost x86_64]#

8. 配置rsyslog日志服務(wù)

[root@localhost x86_64]# vi /etc/rsyslog.conf

#加入如下內(nèi)容：

local1.debug?? /var/log/bash

[root@localhost x86_64]# service rsyslog restart

關(guān)閉系統(tǒng)日志記錄器：?????????????????????????????????????? [確定]

啟動(dòng)系統(tǒng)日志記錄器：?????????????????????????????????????? [確定]

9. 查看日志記錄，成功存儲(chǔ)用戶(hù)操作日志，與history日志分開(kāi)存儲(chǔ)，并且只有root權(quán)限可以操作該日志文件，如果配置日志服務(wù)器，操作日志將傳送到遠(yuǎn)程服務(wù)器。

[root@localhost ~]# tail -f /var/log/bash

Apr 13 00:47:11 localhost bash: HISTORY: PPID=2471 PID=2473 SID=2473 UID=0 User=root ifconfig

Apr 13 00:47:12 localhost bash: HISTORY: PPID=2471 PID=2473 SID=2473 UID=0 User=root ls

Apr 13 01:21:20 localhost -bash: HISTORY: PPID=26157 PID=26159 SID=26159 UID=0 User=root df -h

Apr 13 01:21:33 localhost -bash: HISTORY: PPID=26157 PID=26159 SID=26159 UID=0 User=root useradd abc

Apr 13 01:21:38 localhost -bash: HISTORY: PPID=26157 PID=26159 SID=26159 UID=0 User=root passwd abc

Apr 13 01:21:42 localhost -bash: HISTORY: PPID=26157 PID=26159 SID=26159 UID=0 User=root su - abc

Apr 13 01:21:44 localhost -bash: HISTORY: PPID=26192 PID=26193 SID=26159 UID=500 User=abc exit

二、rsyslog日志服務(wù)器配置

1. 日志服務(wù)器配置

# vi /etc/rsyslog.conf

將其中下面四行的注釋取消

$ModLoad imudp

$UDPServerRun 514

$ModLoad imtcp

$InputTCPServerRun 514

在#### GLOBAL DIRECTIVES ####中加入如下內(nèi)容：

$template IpTemplate,"/var/log/%FROMHOST-IP%.log"

*.* ?IpTemplate

& ~

說(shuō)明：實(shí)現(xiàn)在接收遠(yuǎn)程的日志為客戶(hù)端IP地址命名。

然后重新啟動(dòng)rsyslogd服務(wù)

# service rsyslog restart

2. 日志客戶(hù)端配置

# vi /etc/rsyslog.conf

local1.debug??? @@192.168.0.66

# 然后重新啟動(dòng)rsyslogd服務(wù)

# service rsyslog restart

3. 查看結(jié)果，已經(jīng)可以接收結(jié)果了。

[root@testdb log]# cd /var/log

[root@testdb log]# ll
