Notes on the deployment of clamav antivirus software
Environment: Centos 7.2
Software: clamav
Step 1: download Clamav
Wget http://www.clamav.net/downloads/production/clamav-0.99.2.tar.gz
Step 2: create clamav users and groups
Groupadd clamav useradd-g clamav clamav
Step 3: compile and install
Tar xf clamav-0.99.2.tar.gzcd clamav-0.99.2./configure-- prefix=/usr/local/clamav & & make & & make install
Step 4: configure
Mkdir / usr/local/clamav/logs (log storage directory) touch / usr/local/clamav/logs/clamd.logtouch / usr/local/clamav/logs/freshclam.logmkdir / usr/local/clamav/updata (clanav virus library directory) chown-R root.clamav / usr/local/clamav/chown-R clamav.clamav / usr/local/clamav/updata/chown clamav.clamav / usr/local/clamav/logs/clamd.logchown clamav.clamav / usr/local/clamav/logs/freshclam.logcd / usr/ Local/clamav/etccp clamd.conf.sample clamd.confcp freshclam.conf.sample freshclam.confvi clamd.conf#Example commented out this line. LogFile / usr/local/clamav/logs/clamd.log PidFile / usr/local/clamav/updata/clamd.pid DatabaseDirectory / usr/local/clamav/updatavi freshclam.conf#Example commented out this line. DatabaseDirectory / usr/local/clamav/updataUpdateLogFile / usr/local/clamav/logs/freshclam.logPidFile / usr/local/clamav/updata/freshclam.pid
Step 5: upgrade the virus bank
/ usr/local/clamav/bin/freshclam
The process takes a long time, about half an hour. Let's wait. You can turn on screen to do it.
/ usr/local/clamav/bin/clamscan-- remove (kill the current directory and delete infected files)
Step 6: plan tasks
Application of actual production environment
Generally use scheduled tasks to let the server regularly follow the new and regular antivirus every night. Save the antivirus log, my crontab file is as follows
Yum install crontabs-y/sbin/service crond start / / start the service / sbin/service crond stop / / close the service / sbin/service crond restart / / restart the service / sbin/service crond reload / / reload the configuration chkconfig crond on / / boot centos6systemctl enable crond.service / / boot boot centos7crontab-e1 3 * / usr/local/clamav/bin/freshclam 303 * / usr/ Local/clamav/bin/clamscan-- infected-r /-- remove-l / var/log/clamscan.log
