elasticsearch将不会启动:存在Seccomp，但是引导检查失败(Centos 7/ES 6.4.2)

问题描述

CentOS Linux版本7.5.1804(核心)

CentOS Linux release 7.5.1804 (Core)

配置生产集群，ES拒绝启动:

Configuring a production cluster, and ES refuses to start:

1:33:56,454][INFO ][o.e.t.TransportService   ] [node-68795-C] publish_address {192.168.200.162:9300}, bound_addresses {192.168.200.162:9300}
[2018-10-28T21:33:56,467][INFO ][o.e.b.BootstrapChecks    ] [node-68795-C] bound or publishing to a non-loopback address, enforcing bootstrap checks
[2018-10-28T21:33:56,494][ERROR][o.e.b.Bootstrap          ] [node-68795-C] node validation exception
[1] bootstrap checks failed
[1]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

好，所以我要检查seccomp的存在:

OK, so I go to check the presence of seccomp:

[$]# cat /boot/config-`uname -r` | grep CONFIG_SECCOMP=
CONFIG_SECCOMP=y
[$]# CONFIG_SECCOMP=y

因此，外观和气味都像seccomp.

So, looks and smells like seccomp is present.

接下来是什么?

推荐答案

根本原因:/tmp被挂载为noexec

The root cause: /tmp was mounted as noexec

事实证明，如果/tmp为noexec，则两次或三个引导程序检查将失败.

It turns out that two or three bootstrap checks fail if /tmp is noexec.

解决/tmp，所有其他问题都解决了！

Solve for /tmp, and all the other issues are resolved!
