如果系統運行著sendmail就要把sendmail的守護進程殺掉，然後抓了qmail1.03.tar.gz,UCspi-tcp-0.88.tar.gz,daemontools-0.70.tar.gz這三個包，把他們扔/usr/local/src下面解壓開，然後要建一些必要的目錄 cd qmail-1.03 mkdir /var/qmail ln -s /usr/man /var/qmail/man mkdir /etc/qmail ln -s /etc/qmail /var/qmail/control ln -s /usr/sbin /var/qmail/bin 接著建安裝qmail需要的組和用戶: groupadd nofiles useradd alias -g nofiles -d /var/qmail/alias -s /nonexistent useradd qmaild -g nofiles -d /var/qmail -s /nonexistent useradd qmaill -g nofiles -d /var/qmail -s /nonexistent useradd qmailp -g nofiles -d /var/qmail -s /nonexistent groupadd qmail useradd qmailq -g qmail -d /var/qmail -s /nonexistent useradd qmailr -g qmail -d /var/qmail -s /nonexistent useradd qmails -g qmail -d /var/qmail -s /nonexistent 然後開始編譯qmail: make setup check 接著就配置域名了(這個需要你的機器域名能在dns上找到): ./config(如果確定域名沒錯，也可以用./config-fast hostname.domainname) 然後要編譯ucspi-tcp: 進入剛才ucspi-tcp解開的目錄，執行: make make setup check 接著編譯daemontools,也是進入解壓的目錄，執行 make make setup check 下來就開始寫一些qmail執行必須的腳本了，先是 vi /var/qmail/rc 腳本內容是： #!/bin/sh # Using stdout for logging # Using control/defaultdelivery from qmail-local to deliver messages by default exec env - PATH="/var/qmail/bin:$PATH" qmail-start "`cat /var/qmail/control/defaultdelivery`" 最後 chmod 755 /var/qmail/rc echo ./Maildir/ >/var/qmail/control/defaultdelivery(我用的是Maildir) 然後就是log文件了: mkdir /var/log/qmail mkdir -p /var/qmail/supervise/qmail-send/log mkdir -p /var/qmail/supervise/qmail-smtpd/log chmod +t /var/qmail/supervise/qmail-send chmod +t /var/qmail/supervise/qmail-smtpd 建立/var/qmail/supervise/qmail-send/run文件,內容為： #!/bin/sh exec /var/qmail/rc 建立/var/qmail/supervise/qmail-send/log/run文件，內容為: #!/bin/sh exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t /var/log/qmail 建立/var/qmail/supervise/qmail-smtpd/run文件，內容: #!/bin/sh QMAILDUID=`id -u qmaild` NOFILESGID=`id -g qmaild` MAXSMTPD=`cat /var/qmail/control/concurrencyincoming` exec /usr/local/bin/softlimit -m 2000000 /usr/local/bin/tcpserver -v -p -x /etc/tcp.smtp.cdb -c "$MAXSMTPD" -u "$QMAILDUID" -g "$NOFILESGID" 0 smtp /var/qmail/bin/qmail-smtpd 2>&1 建立/var/qmail/supervise/qmail-smtpd/log/run文件，內容: #!/bin/sh exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t /var/log/qmail/smtpd 把以上四個run文件chmod 755 然後執行: echo 20 > /var/qmail/control/concurrencyincoming chmod 644 /var/qmail/control/concurrencyincoming 來建立qmail必須的concurrencyincoming文件 同時建立標准的log目錄: mkdir -p /var/log/qmail/smtpd chown qmaill /var/log/qmail /var/log/qmail/smtpd 最關鍵的一步是建立qmail控制腳本,建立/etc/rc.d/init.d/qmail這個文件，內容: 腳本的HELP那塊有些折行，盡量把他們弄一行. #!/bin/sh PATH=/var/qmail/bin:/usr/local/bin:/usr/bin:/bin eXPort PATH case "$1" in start) echo -n "Starting qmail: svscan" cd /var/qmail/supervise env - PATH="$PATH" svscan & echo $!
