【问题描述】：

我已经尝试了数周来配置 rundeck 以在 Centos7 虚拟机上使用我的 gmail smtp 设置发送电子邮件。我确实为服务器配置了一个 ssl 证书（我购买的）。不确定这是否与它有关。到目前为止，我有：

将“/etc/rundeck/rundeck-config.properties”文件转换为 “/etc/rundeck/rundeck-config.groovy”文件
使用以下设置更新“/etc/sysconfig/rundeckd”文件。 “导出 RUNDECK_WITH_SSL=true export RDECK_CONFIG_FILE="/etc/rundeck/rundeck-config.groovy"
使用以下文本编辑了我的“/etc/rundeck/rundeck-config.groovy”。

loglevel.default="INFO"
rdeck.base="/var/lib/rundeck"
rss.enabled=false

grails.mail.default.from="user@gmail.com"

dataSource.dbCreate = "update"
dataSource.url = "jdbc:h2:file:/var/lib/rundeck/data/rundeckdb;MVCC=true;TRACE_LEVEL_FILE=4"

grails {
  mail {
        host = "smtp.gmail.com"
        username = "user@gmail.com"
        port = 465
        password = "password"
        props = ["mail.smtp.auth":"true",
                "mail.smtp.port":"465",
                "mail.smtp.starttls.enable":"true",
                "mail.smtp.socketFactory.port":"465",
                "mail.smtp.socketFactory.fallback":"false"]
  }
}
grails.serverURL="https://rundeck-server:4443"
rundeck.log4j.config.file = "/etc/rundeck/log4j.properties"

如果我使用端口 465 运行它，我会收到以下错误。

2019-01-03 14:57:26.260 ERROR --- [eduler_Worker-1] rundeck.services.NotificationService     : Error sending notification email to user@gmail.com for Execution 231: Mail server connection failed; nested exception is javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465, response: -1. Failed messages: javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465, response: -1

如果我使用端口 587 进行配置，我会在“/var/log/rundeck/service.log”中收到以下错误

2019-01-03 15:05:52.121 ERROR --- [eduler_Worker-1] rundeck.services.NotificationService     : Error sending notification email to user@gmail.com for Execution 233: Mail server connection failed; nested exception is javax.mail.MessagingException: Could not convert socket to TLS;
  nested exception is:

  nested exception is:
	javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

另外，我安装了 mailx，虽然日志中有错误，但当我运行以下“echo “Your message” | mail -v -s “Message Subject” user@gmail.com 命令时，它成功发送了一封电子邮件.输出是

我在“/etc/mail.rc”文件的底部添加了以下内容

set smtp=smtps://smtp.gmail.com:465
set smtp-auth=login
set smtp-auth-user=USER.GMAIL.COM
set smtp-auth-password='password'
set ssl-verify=ignore
set nss-config-dir=/etc/pki/nssdb/

【问题讨论】：

所以问题出在我为 rundeck 服务器配置的 SSL 证书上。我使用未配置 ssl 证书的新 rundeck 服务器尝试了电子邮件设置，并且效果很好。

标签： ssl smtp gmail rundeck mailx

【解决方案1】：

我使用 /etc/rundeck/rundeck-config.groovy 中的这些设置从我的 gmail 帐户发送电子邮件

grails {
  mail {
        host = "smtp.gmail.com"
        username = "USER"
        port = 587
        password = "PASSWORD"
        props = ["mail.smtp.starttls.enable":"true","mail.smtp.auth":"true","mail.smtp.socketFactory.port":"587","mail.smtp.socketFactory.fallback":"false"]
  }
}
