### 步骤一：下载编译安装包 ###

> \[root@liang /root 20:00:48\]\#cd /server/Package/  
> \[root@liang /server/Package 20:00:50\]\#wget [http://www.clamav.net/downloads/production/clamav-0.101.2.tar.gz][http_www.clamav.net_downloads_production_clamav-0.101.2.tar.gz]

### 步骤二：解压编译安装clamav ###

> \[root@liang /server/Package 20:01:05\]\#tar zxf clamav-0.101.2.tar.gz  
> \[root@liang /server/Package 20:01:20\]\#cd clamav-0.101.2  
> \[root@liang /server/Package/clamav-0.101.2 20:02:24\]\#yum install gcc-c++ openssl openssl-devel -y  
> \[root@liang /server/Package/clamav-0.101.2 11:07:27\]\#./configure --prefix=/usr/local/clamav-0.101.2  
> \[root@liang /server/Package/clamav-0.101.2 11:07:49\]\#make && make install

### 步骤三：添加软连接 ###

> \[root@liang /server/Package/clamav-0.101.2 11:10:30\]\#ln -s /usr/local/clamav-0.101.2/ /server/clamav  
> \[\[root@liang /server/Package/clamav-0.101.2 11:10:30\]\#lln -s /usr/local/clamav-0.101.2/bin/\* /usr/local/bin/  
> \[root@liang /server/Package/clamav-0.101.2 11:10:30\]\#lln -s /usr/local/clamav-0.101.2/sbin/\* /usr/local/sbin/

### 步骤四：创建相关文件 ###

> \[root@liang /server/Package/clamav-0.101.2 11:10:56\]\#cd /server/clamav/  
> \[root@liang /server/clamav 11:11:09\]\#mkdir logs  
> \[root@liang /server/clamav 11:11:31\]\#touch logs/clamd.log  
> \[root@liang /server/clamav 11:11:44\]\#touch logs/freshclam.log  
> \[root@liang /server/clamav 11:11:53\]\#mkdir updata

### 步骤五：修改配置文件 ###

> \[root@liang /server/clamav/etc 11:12:40\]\#ls  
> clamd.conf.sample freshclam.conf.sample  
> \[root@liang /server/clamav/etc 11:12:40\]\#cp clamd.conf.sample clamd.conf  
> \[root@liang /server/clamav/etc 11:12:57\]\#cp freshclam.conf.sample freshclam.conf  
> \[root@liang /server/clamav/etc 11:14:07\]\#cat >> clamd.conf<<-eof  
> > LocalSocket /server/clamav/clamd.socket  
> > PidFile /server/clamav/updata/clamd.pid  
> > DatabaseDirectory /server/clamav/updata  
> > LogFile /server/clamav/logs/clamd.log  
> > eof  
> \[root@liang /server/clamav/etc 11:15:08\]\#cat >>freshclam.conf<<-eof  
> > DatabaseDirectory /server/clamav/updata  
> > UpdateLogFile /server/clamav/logs/freshclam.log  
> > PidFile /server/clamav/updata/freshclam.pid  
> > eof  
> \[root@liang /server/clamav/etc 11:17:02\]\#grep -n “\#Example” clamd.conf freshclam.conf  
> clamd.conf:8:\#Example \#原本是未注释的，添加\#进行注释  
> freshclam.conf:8:\#Example \#原本是未注释的，添加\#进行注释

### 步骤六：创建clamav用户并授权 ###

> \[root@liang /server/clamav/etc 11:18:15\]\#useradd -M -s /sbin/nologin clamav  
> \[root@liang /server/clamav/etc 11:19:10\]\#chown -R clamav:clamav /usr/local/clamav-0.101.2/

### 步骤七：启动clamd ###

> \[root@liang /server/clamav/etc 11:20:56\]\#clamd start  
> LibClamAV Error: cl\_load(): No such file or directory: /server/clamav/updata  
> ERROR: Can’t get file status  
> 启动报错，提示的意思是 /server/clamav/updata目录中没有东西，需要freshclam 更新病毒库  
> \[root@liang /server/clamav/etc 11:41:18\]\#freshclam

### 步骤八：添加定时任务，扫描会占用IO ###

> \[root@liang /server/clamav/etc 12:04:51\]\#crontab -l  
> \*/5 \* \* \* \* /usr/sbin/ntpdate [ntp1.aliyun.com][] >/dev/null 2>&1  
> 00 00 \* \* \* /usr/local/bin/freshclam  
> 00 00 \* \* \* /usr/local/bin/clamscan -r /tmp/ --remove
