安装ulogd步骤

安装ulogd步骤 ulogd是一款基于Netfilter项目的日志记录和分析工具，主要用于记录和分析网络流量。下面是安装ulogd的步骤： 1. 安装ulogd 下载ulogd的源代码并编译安装： svn co https://svn.netfilter.org/netfilter/trunk/ulog/ulogd/ cd ulogd autoconf ./configure --with-mysql make && make install 2. 配置ulogd 将ulogd的配置文件复制到相应的目录： cp ulogd.init /etc/init.d/ulogd cp ulogd.logrotate /etc/logrotate.d/ulogd cp ulogd.8 /usr/local/share/man/man8 然后，编辑ulogd的配置文件，添加插件和数据库连接信息： vi /etc/init.d/ulogd daemon /usr/local/sbin/ulogd -d vi /usr/local/etc/ulogd.conf #plugin="/usr/local/lib/ulogd/ulogd_LOGEMU.so" plugin="/usr/local/lib/ulogd/ulogd_MYSQL.so" [MYSQL] table="ulog" pass="ulog" user="ulog" db="ulog" host="localhost" 3. 安装nulog nulog是一个基于PHP的Web接口，用于可视化ulogd的日志记录。下载nulog的源代码并安装： svn co http://software.inl.fr/svn/mirror/edenwall/nulog/trunk/ nulog cd nulog WEBDIR="var/www/html/nulog" make install chmod -x `find /var/www/html/nulog -type f` 然后，编辑nulog的配置文件： cd /var/www/html/nulog cp config.template.php config.php vi include/config.php $lang="en"; $nufw_enabled="no"; $netfilter_log_drop=0; $url_base="http://your.host/nulog/"; $machine="YOUR_HOSTNAME"; $db_host="localhost"; $db_ulog="ulog"; $db_user="ulog"; $db_pwd="ulog"; 4. 配置数据库 创建数据库和用户： mysql -u root -p -A mysql create database ulog; grant all privileges on ulog.* to ulog@localhost identified by 'ulog'; flush privileges; exit 5. 安装iptables规则 安装iptables规则以记录网络流量： iptables -A INPUT -p tcp --dport 80 -j ULOG iptables -A FORWARD -j ULOG iptables -N BAN_SSH iptables -A FORWARD -s 192.168.1.0/24 -p tcp --dport 22 -j BAN_SSH iptables -A BAN_SSH -j ULOG iptables -A BAN_SSH -j DROP 本文档将ulogd的安装步骤分解成五个部分，包括安装ulogd、配置ulogd、安装nulog、配置数据库和安装iptables规则。每个部分都提供了详细的命令行命令和配置文件编辑指南，以帮助读者快速安装和配置ulogd。
