安裝 Clam AntiVirus
首先从[url]http://www.clamav.net/[/url]下载clamav0.90包
useradd clamav
./configure
make
make install
注:安装过程中有可能会出现zlib版本不够的情况,请去[url]http://www.zlib.net/[/url]下载最新的zlib进行安装
安装过程:
./configure
make
make install
安裝 HAVP
从[url]http://www.server-side.de/download.htm[/url]下载havp 0.86的包
useradd havp
./configure
make
make install
chown -R havp.havp /var/log/havp /var/tmp/havp /var/run/havp
vi /usr/local/etc/havp/havp.config
### 注释以下这行
#REMOVETHISLINE deleteme
### ClamAV Library Scanner (libclamav) → 由 HAVP 直接取用 ClamAV 的病毒资料库
ENABLECLAMLIB true
CLAMDBDIR /var/lib/clamav
### ClamAV Socket Scanner (clamd) → 交由 clamd 扫毒 (须先启动 clamd), 以上两者择一使用即可,我使用的上面那种模式)
ENABLECLAMD true
CLAMDSOCKET /tmp/clamd
其他效能相关的设定:
### 理論上越多的執行緒效能效能越好, 但仍需視伺服器資源而定
SERVERNUMBER 40
MAXSERVERS 200
### 只記錄 error log. 較少的 Log 記錄可減輕伺服器負擔
LOGLEVEL 0
### 不對圖片檔掃毒, 可減輕 CPU 負擔
SCANIMAGES false
### 这个是havp的监听端口,默认是8080,因为8080是tomcat的默认端口,所以我改成3129了,
PORT=3129
挂载独立磁盘区 /var/tmp/havp (一定要加上 -o mand 參數)
mount -o mand /dev/hda3 /var/tmp/havp
如果沒有多餘的 device 可以掛載, 可參考以下兩種方法:
a. 用記憶體建立虛擬磁碟
mkfs -t ext2 /dev/ram0 8192 (建立 8MB RAM Disk)
mount -o mand /dev/ram0 /var/tmp/havp
b. 使用硬碟空間建立虛擬磁碟
dd if=/dev/zero of=/root/havp_tmp.img bs=128K count=1 seek=1024 (建立 128MB Virtual Disk)
mkfs.ext2 /root/havp_tmp.img
mount -o loop,mand /root/havp_tmp.img /var/tmp/havp
ps. HAVP 可扫描的档案大小将受限于这里所挂载的磁盘空間
更新 shared libraries 资料库 (for ClamAV)
vi /etc/ld.so.conf --> 加入: /usr/local/lib
ldconfig
启动 HAVP
/usr/local/sbin/havp &
squid和havp的捆绑
编辑squid.conf文件
加入如下两行
cache_peer 127.0.0.1 parent 3129 0 no-query no-digest no-netdb-exchange default
cache_peer_access 127.0.0.1 allow all
到目前位置squid+clamav+havp就已经配置完成了
使用squid做代理然后去[url]http://www.eicar.org/anti_virus_test_file.htm[/url]这个网站进行测试吧
HAVP 會直接使用 ClamAV 的 Library, 所以 ClamAV 的服務是不需要啟動的.
您只要使用 ClamAV 的 freshclam 來更新 ClamAV 的病毒碼就行了,
方法如下:
1. 以 crontab 排程: 0 0 * * * /usr/local/bin/freshclam --verbose(每天午夜更新病毒碼)
Clamav升级配置文件
vi /usr/local/clamav/etc/freshclam.conf
##
## Example config file for freshclam
## Please read the clamav.conf(5) manual before editing this file.
## This file may be optionally merged with clamav.conf.
##
# You can change the default database directory here.
#DatabaseDirectory /var/lib/clamav
# Path to the log file (make sure it has proper permissions)
[b]UpdateLogFile /var/log/freshclam.log[/b]
# Enable verbose logging.
[b]LogVerbose[/b]
# Use system logger (can work together with UpdateLogFile).
[b]LogSyslog[/b]
# By default when freshclam is started by root it drops privileges and
# switches to the "clamav" user. You can change this behaviour here.
#DatabaseOwner clamav
# The main database mirror is database.clamav.net (this is a round-robin
# DNS that points to many mirrors on the world) and in most cases you
# SHOULD NOT change it.
