Monit发送空邮件

Question

我配置了Monit (5.27.1版)，在重新加载monit之后，我收到了一封“空”邮件。我找了好几个小时，我找不着路.似乎“环境变量”仍然是空的。但为什么？(所有个人资料均属虚假)

我将/etc/monit/monitrc配置为：

cat > /etc/monit/monitrc << EOF
set daemon 120
with start delay 240


set logfile /var/log/monit.log
set pidfile /var/run/monit.pid


set eventqueue
basedir /var/lib/monit/events
slots 100


set mailserver 127.0.0.1
    with timeout 10 seconds


set mail-format {
    from: Monit Support 
    subject: monit alert -- $EVENT $SERVICE
    message: $EVENT Service $SERVICE
    Date: $DATE
    Action: $ACTION
    Host: $HOST
    Description: $DESCRIPTION
    Your faithful employee,
    Monit
}

set alert alexandre.gigoga@gmail.com

set httpd
port 18385
with ssl {
    pemfile: /etc/ssl/private/monit.pem
}
allow Alex_8xws2_admin:p2pp85zl


include /etc/monit/conf.d/*
include /etc/monit/conf-enabled/*
EOF

在"$ monit重新加载“之后，我收到了以下电子邮件：(日期、操作、主机、描述为空。为什么?)

以防万一这是我的‘/etc/主机’：

127.0.0.1       localhost

::1     localhost       ip6-localhost   ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

41.27.221.113   vps-msxp453234.vps.domain.net        vps-msxp453234

我遗漏了什么？

Answer 1

您的shell只需用来自env的值替换以$开头的任何内容。因此，您基本上没有将$写入monit的配置文件。

尝试cat /etc/monit/monitrc或查看in nano或vim.该文件将不包含monit替换的变量。

解决方案是在任何$前面加上反斜杠\$，或者不使用cat，而是使用编辑器.
