elasticsearch 无法启动:Seccomp 存在,但 bootstrap 检查失败 (Centos 7 / ES 6.4.2)

elasticsearch will not start: Seccomp is present, but bootstrap check fails (Centos 7 / ES 6.4.2)

CentOS Linux 发行版 7.5.1804(核心)

配置生产集群,ES拒绝启动:

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}

[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

好的,那我去看看有没有seccomp:

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

因此,看起来和闻起来都像是存在 seccomp。

下一步是什么?

根本原因:/tmp 被挂载为 noexec

事实证明,如果 /tmp 是 noexec,则两三个 bootstrap 检查会失败。

解决/tmp,其他问题都解决了!
