qmail安装历程

作者:webmaster

  最近公司要开展虚拟主机业务,需要在一台mail服务器上绑定多个域名,于是呢,就想到qmail这位老人家了,照ideal的方法有点问题,就只好去看老外的life with qmail了,hehe

  现在大约讲讲我的安装过程:

  如果系统运行着sendmail就要把sendmail的守护进程杀掉,然后抓了qmail1.03.tar.gz,ucspi-tcp-0.88.tar.gz,daemontools-0.70.tar.gz这三个包,把他们扔/usr/local/src下面解压开,然后要建一些必要的目录

  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

  接着建安装qmail需要的组和用户:

  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

  然后开始编译qmail:

  make setup check

  接着就配置域名了(这个需要你的机器域名能在dns上找到):

  ./config(如果确定域名没错,也可以用./config-fast hostname.domainname)

  然后要编译ucspi-tcp:

  进入刚才ucspi-tcp解开的目录,执行:

  make

  make setup check

  接着编译daemontools,也是进入解压的目录,执行

  make

  make setup check

  下来就开始写一些qmail执行必须的脚本了,先是

  vi /var/qmail/rc

  脚本内容是:

  #!/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`"

  最后

  chmod 755 /var/qmail/rc

  echo ./Maildir/ >/var/qmail/control/defaultdelivery(我用的是Maildir)

  然后就是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,内容为:

  #!/bin/sh

  exec /var/qmail/rc

  建立/var/qmail/supervise/qmail-send/log/run文件,内容为:

  #!/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,内容:

  #!/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,内容:

  #!/bin/sh

  exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t /var/log/qmail/smtpd

  把以上四个run文件chmod 755

  然后执行:

  echo 20 > /var/qmail/control/concurrencyincoming

  chmod 644 /var/qmail/control/concurrencyincoming

  来建立qmail必须的concurrencyincoming文件

  同时建立标准的log目录:

  mkdir -p /var/log/qmail/smtpd

  chown qmaill /var/log/qmail /var/log/qmail/smtpd

  最关键的一步是建立qmail控制脚本,建立/etc/rc.d/init.d/qmail这个文件,内容:

  脚本的HELP那块有些折行,尽量把他们弄一行.

  #!/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 $! > /var/run/svscan.pid

  echo "."

  ;;

  stop)

  echo -n "Stopping qmail: svscan"

  kill `cat /var/run/svscan.pid`

  echo -n " qmail"

  svc -dx /var/qmail/supervise/*

  echo -n " logging"

  svc -dx /var/qmail/supervise/*/log

  echo "."

  ;;

  stat)

  cd /var/qmail/supervise

  svstat * */log

  ;;

  doqueue|alrm)

  echo "Sending ALRM signal to qmail-send."

  svc -a /var/qmail/supervise/qmail-send

  ;;

  queue)

  qmail-qstat

  qmail-qread

  ;;

  reload|hup)

  echo "Sending HUP signal to qmail-send."

  svc -h /var/qmail/supervise/qmail-send

  ;;

  pause)

  echo "Pausing qmail-send"

  svc -p /var/qmail/supervise/qmail-send

  echo "Pausing qmail-smtpd"

  svc -p /var/qmail/supervise/qmail-smtpd

  ;;

  cont)

  echo "Continuing qmail-send"

  svc -c /var/qmail/supervise/qmail-send

  echo "Continuing qmail-smtpd"

  svc -c /var/qmail/supervise/qmail-smtpd

  ;;

  restart)

  echo "Restarting qmail:"

  echo "* Stopping qmail-smtpd."

  svc -d /var/qmail/supervise/qmail-smtpd

  echo "* Sending qmail-send SIGTERM and restarting."

  svc -t /var/qmail/supervise/qmail-send

  echo "* Restarting qmail-smtpd."

  svc -u /var/qmail/supervise/qmail-smtpd

  ;;

  cdb)

  tcprules /etc/tcp.smtp.cdb /etc/tcp.smtp.tmp < /etc/tcp.smtp

  chmod 644 /etc/tcp.smtp*

  echo "Reloaded /etc/tcp.smtp."

  ;;

  help)

  cat < stop -- stops mail service (smtp connections refused, nothing goesout)

  start -- starts mail service (smtp connection accepted, mail cangoout)

  pause -- temporarily stops mail service (connections accepted,nothing leaves)

  cont -- continues paused mail service

  stat -- displays status of mail service

  cdb -- rebuild the tcpserver cdb file for smtp

  restart -- stops and restarts smtp, sends qmail-send a TERM &restarts it

  doqueue -- sends qmail-send ALRM, sche易做图ng queued messages fordelivery

  reload -- sends qmail-send HUP, rereading locals and virtualdomains

  queue -- shows status of queue

  alrm -- same as doqueue

  hup -- same as reload

  HELP

  ;;

  *)

  echo "Usage: $0 {start|stop|restart|doqueue|reload|stat|pause|cont|cdb|queue|help}"

  exit 1

  ;;

  esac

  exit 0

  然后建立软连接让各个启动级别能不同的需要使用qmail控制脚本

  ln -s qmail /etc/rc.d/rc0.d/K30qmail

  ln -s qmail /etc/rc.d/rc1.d/K30qmail

  ln -s qmail /etc/rc.d/rc2.d/S80qmail

  ln -s qmail /etc/rc.d/rc3.d/S80qmail

  ln -s qmail /etc/rc.d/rc4.d/S80qmail

  ln -s qmail /etc/rc.d/rc5.d/S80qmail

  ln -s qmail /etc/rc.d/rc6.d/K30qmail

  然后就要建立qmail的访问控制文件了,执行
