如何使用Fedora 13的greylist 套件在CentOS上
1, wget http://software.virtualmin.com/gpl/centos/5/SRPMS/fedora-usermgmt-0.9-1.el5.src.rpm and build the source rpm
rpm -ivh /usr/src/redhat/RPMS/noarch/fedora-usermgmt-0.9-1.noarch.rpm /usr/src/redhat/RPMS/noarch/fedora-usermgmt-core-0.9-1.noarch.rpm /usr/src/redhat/RPMS/noarch/fedora-usermgmt-default-fedora-setup-0.9-1.noarch.rpm /usr/src/redhat/RPMS/noarch/fedora-usermgmt-shadow-utils-0.9-1.noarch.rpm /usr/src/redhat/RPMS/noarch/fedora-usermgmt-devel-0.9-1.noarch.rpm
2, yum -y install sendmail-devel geoip-* –enablerepo dag
3, wget ftp://ftp.muug.mb.ca/mirror/fedora/linux/development/rawhide/source/SRPMS/milter-greylist-4.2.4-1400.fc14.src.rpm
4, rpm -ivh milter-greylist-4.2.3-1400.fc14.src.rpm –nomd5
vim /usr/src/redhat/SPECS/milter-greylist.spec
define the following variable
%global username smmsp
%global vardir %_var/%name
%global dbdir %vardir
%global rundir %_var/%name
%global __chkconfig /sbin/chkconfig
delete
Requires: init(%name)
delete
–enable-dnsrbl \
delete the following (we want /var/milter-greylist/ path)
for i in `find -type f`; do
sed -e ‘s!/var/milter-greylist/milter-greylist.sock!%rundir/milter-greylist.sock!g;
s!/var/milter-greylist/greylist.db!%dbdir/greylist.db!g;
s!/var/milter-greylist/milter-greylist.pid!%_var/run/milter-greylist.pid!g;
‘ "$i" >"$i.tmp"
cmp -s "$i" "$i.tmp" || cat "$i.tmp" >"$i"
rm -f "$i".tmp
done
change this line
touch $RPM_BUILD_ROOT%_var/run/milter-greylist.pid
to
touch $RPM_BUILD_ROOT%rundir/milter-greylist.pid
change this line
touch $RPM_BUILD_ROOT%_var/run/milter-greylist.sock
to
touch $RPM_BUILD_ROOT%rundir/milter-greylist.sock
change this line
%ghost %_var/run/milter-greylist.pid
to
%ghost %rundir/run/milter-greylist.pid
%ghost %rundir/milter-greylist.sock
%dir /usr/src/debug/%name-4.2.3/*
/usr/lib/debug/usr/sbin/%name.debug
%dir %vardir/%name.sock
%vardir/%name.pid
rpmbuild -ba /usr/src/redhat/SPECS/milter-greylist.spec
rpm -Uvh /usr/src/redhat/RPMS/noarch/milter-greylist-4.2.3-1400.noarch.rpm
edit /etc/mail/greylist.conf, adding the following
geoipdb "/usr/share/GeoIP/GeoIP.dat"
spamdsock inet "127.0.0.1:783"
dacl blacklist spamd > 7 msg "Your message is considered spam."
dacl greylist spamd > 6 delay 6h autowhite 3h msg "greylist in action (6) , please come back later. call 886-921361388 for help!"
dacl greylist spamd > 5 delay 1h autowhite 40h msg "greylist in action (5), please come back later. call 886-921361388 for help!"
dacl greylist spamd > 4 delay 30m autowhite 110h msg "greylist in action (4), please come back later. call 886-921361388 for help!"
dacl greylist spamd > 3 delay 10m autowhite 180h msg "greylist in action (3), please come back later. call 886-921361388 for help!"
racl whitelist default
racl greylist default delay 5m autowhite 7d msg "greylist in action (4), please come back later. call 886-921361388 for help!"
now spamassassin must be starting
edit /etc/sysconfig/spamassassin
chkconfig –level 35 spamassassin on
service spamassassin start
service milter-greylist restart

0, 預備工作
安裝 yum-utils
取得 sendmail rpm
yumdownloader sendmail
解開 sendmail-8.13.8-2.el5.i386.rpm
rpm2cpio sendmail-8.13.8-2.el5.i386.rpm | cpio -ivd
(會解出 sendmail 的內含檔案, 取 sendmail.mc)
cp etc/mail/sendmail.mc /etc/mail/sendmail.mc_original, 以此為依據,
1, amavisd-new 網站
http://www.ijs.si/software/amavisd/
2, 停掉 MailScanner
service MailScanner stop
chkconfig –level 35 MailScanner off
3, 安裝
yum -y install amavisd-new amavisd-new-milter clamav clamav-db –enablerepo dag
4, 設定
(1) sendmail
cp /etc/mail/sendmail.mc_original /etc/mail/1.mc
vi 1.mc 加入以下內容
DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0, Name=MTA’)dnl
MASQUERADE_AS(`fhl.net’)
FEATURE(masquerade_envelope)
FEATURE(allmasquerade)
INPUT_MAIL_FILTER(`greylist’, `S=local:/var/milter-greylist/milter-greylist.sock’)
INPUT_MAIL_FILTER(`milter-amavis’, `S=local:/var/amavis/amavis-milter.sock, F=T, T=S:20m;R:20m;E:40m’)dnl
另外要修改 /etc/init.d/amavisd
MILTER_SOCKET="local:/var/amavis/amavis-milter.sock"
/etc/amavisd.conf 也要參照 tech 修改一下
Cent_OS lm_sensors 會動了
趕快紀錄下搞定的方法：
rpm -Uvh http://elrepo.org/linux/elrepo/el5/i386/RPMS/elrepo-release-0.1-1.el5.elrepo.noarch.rpm
vi /etc/yum.repos.d/elrepo.repo
enabled=1 把他enable起來
看kernel版本
yum install kmod-it87-PAE
或
yum install kmod-it87
都 yes 以後，就可以執行
/usr/sbin/sensors-detect
偵測 sensors 。偵測完雖然有錯，但是只要
/etc/init.d/lm_sensors restart
即可用
/usr/bin/sensors 查到資料

有效解決問題。
指令 大概是，先移除套件
rpm -e perl-bignum perl-Math-BigRat perl-Math-BigInt perl-IO perl-File-Temp perl-Sys-Syslog perl-Test-Harness perl-Test-Simple
自己補裝一套
perl -MCPAN -e shell
設定之後
install bignum
install IO
install File::Temp
force install Scalar::Util
install Sys::Syslog
install Test::Harness
install Test::Simple
exit
即可
解決CentOS中Apache導致loading 太高的問題
紀錄一下，免得忘記：
搞了半天，是 php 除錯信號紀錄太多的問題，只要把除錯信息拿掉一些，系統就輕鬆了。
/etc/php.ini 中
把
error_reporting = E_ALL
改成
error_reporting = E_ALL & ~E_NOTICE
立刻改善，差點就去買新機器了。
另外，如果還是需要監測太大的負載，底下這個 script 可以用：
系統 loading 大於 $thresh (此處是 50) 的負荷就會自動重新啟動 httpd
#!/usr/bin/php -q
<?php
$load=(double) join(”,file(‘/proc/loadavg’));
$thresh=50;
if ($load >$thresh)
exec(‘/etc/init.d/httpd restart’);
?>
