我们有一个邮件服务器快要死了,在退役之前正在将帐户迁移到新服务器。该计算机拥有跨 25 个以上域的 800 多个电子邮件帐户,因此在迁移完成之前保持正常运行非常重要。
最近它开始充满错误日志,由于没有空间而卡住mysql,停止邮件流,通常让我头疼。在找到并修复错误的根本问题之前,我想出了一个脚本来检查 Dovecot 和 Amavis-new 是否正在运行,如果没有则重新启动它们。
阅读后: https://stackoverflow.com/a/7096003/4820993
以及其他一些常见示例,我想出了这个。
netstat -an|grep -ce ':993.*LISTEN' >/dev/null 2>&1
if [ $? = 0 ]
then
echo 'Dovecot is up';
else
echo 'Dovecot is down, restarting...';
/etc/init.d/dovecot restart
logger -p mail.info dovecot_keepalive: Dovecot is down, restarting...
fi
/etc/init.d/amavis status |grep -ce 'running' >/dev/null 2>&1
if [ $? = 0 ]
then
echo 'AmavisD is up';
else
echo 'AmavisD is down, restarting...';
/etc/init.d/amavis restart
sleep 2
/etc/init.d/amavis status |grep -ce 'running' >/dev/null 2>&1
if [ $? = 1 ]
then
echo 'AmavisD had a problem restarting, trying to fix it now...';
logger -p mail.info amavis_keepalive: AmavisD had a problem restarting...
output=$(ps aux|grep a\[m\]avisd)
set -- $output
pid=$2
kill $pid
rm /var/run/amavis/amavisd.pid
/etc/init.d/amavis start
else
echo 'AmavisD restarted successfully';
logger -p mail.info amavis_keepalive: AmavisD is down, restarting...
fi
fi
谁知道呢,我可能会让事情变得更加困难,如果是这样,请告诉我!!!
我对照 http://www.shellcheck.net 进行了检查并根据其调试报告进行更新/更正。我正在从其他地方的示例中将其拼凑在一起,并且希望有人在我实现它之前对其进行校对。
检查 dovecot 的第一部分已经作为每 6 小时的 cronjob 运行得很好(是的,服务器搞砸了,我们需要检查它),这是关于 amavis 的部分,我不确定。
最佳答案
您可以使用Monit它将监视您的服务并自行重新启动。
Amavisd:
# File: /etc/monit.d/amavisd
# amavis
check process amavisd with pidfile /var/amavis/amavisd.pid
group services
start program = "/etc/init.d/amavisd start"
stop program = "/etc/init.d/amavisd stop"
if failed port 10024 then restart
if 5 restarts within 5 cycles then timeout
鸽舍:
# File: /etc/monit.d/dovecot
check process dovecot with pidfile /var/run/dovecot/master.pid
start program = "/etc/init.d/dovecot start"
stop program = "/etc/init.d/dovecot stop"
group mail
if failed host localhost port 993 type tcpssl sslauto protocol imap then restart
if failed host localhost port 143 protocol imap then restart
if 5 restarts within 5 cycles then timeout
depends dovecot_init
depends dovecot_bin
check file dovecot_init with path /etc/init.d/dovecot
group mail
check file dovecot_bin with path /usr/sbin/dovecot
group mail
