我正在尝试使用 Ansible（DevOps 工具）在云中创建一个新的 Galera 集群。我可以通过从 SSH shell 发出命令来启动集群，但不能从 Ansible 发出命令。我已将配置简化为两个节点，但无法让第二个节点加入集群。原因似乎是未知错误 141。我找不到有关此错误的任何文档。
失败的原因似乎是：
Jul 28 23:44:00 dev-database2 mysqld: 150729 9:44:00 [Warning] WSREP: 0.0 (dev-database1): State transfer to 1.0 (dev-database2) failed: -141 (Unknown error 141)
有人能解释一下导致这个错误的原因吗？
配置是Ubuntu 14.04，MariaDB 10.0.20，每台机器上使用相同的SSL证书进行rsync复制。
这是尝试加入集群失败的日志。在此期间，其他节点上没有日志记录。

答案1
我们也遇到过这个问题，我花了一段时间才弄清楚发生了什么，因为我设法让 Galera 工作起来，但当我尝试从头开始重复这一切时，它再次失败了。
当生成的进程（例如 SST 备份运行）在启动时尝试写入应该处理其日志消息的输出描述符时失败，似乎会发生不太具描述性的未知错误 -141。
对我来说，线索是，在第二个节点上出现 -141 错误的情况下，我还注意到我没有从第一个节点上的 Galera 收到任何日志消息，即使在第二个节点上我可以清楚地看到 Galera 已经经历了完整的协商并成功加入集群，这通常会在第一个节点上记录至少 40 行信息。
我认为您可能会发现，使用自动化工具时会发生这种情况，而使用 shell 时不会发生这种情况的原因是，mysql 配置为将日志写入 syslog，但当您使用自动化工具启动或重新启动 mysql 时，记录器子进程会在启动时死亡，而不是成功启动。然后写入此描述符会失败。Mysql 本身似乎可以优雅地处理这个问题，忽略它，而 SST 脚本则不会，因此崩溃。
那么，为什么 logger 子进程在自动化工具下无法启动，而在 shell 上却可以启动呢？这似乎是由于 PTY 分配时间太短造成的 - 我认为具体问题是，如果在运行命令后立即关闭 PTY，而该命令尚未分叉或设置，这会破坏它。
对于使用 ruby 脚本 (capistrano v2) 的我来说，我只需将 :pty => false 添加到我的运行命令中，这样 PTY 就不会被分配。但我不知道是否有办法使用 Ansible 来做到这一点？
（您也可以通过在 nohup 之类的环境下运行服务重启脚本来解决这个问题，尽管这会产生不良的副作用，例如生成 nohup.out 文件。我的理解是 HUP 信号本身不是问题，因为当我使用 :pty => false 选项时，我不需要做任何事情来放弃该进程。）
答案2
根据https://jira.mariadb.org/browse/MDEV-13517您可以尝试通过禁用 MariaDB 中的 syslog 并启用错误日志来解决该问题，配置如下：
[mysqld_safe]
skip_syslog
[mysqld]
log_error=/your/path/error.log
