# seccomp是linux kernel从2..23版本开始所支持的一种安全机制，seccomp（安全计算模式的简称）是Linux内核中的计算机安全设施。 它被合并到2005年3月8日发布的内核版本2..12中的Linux内核主线上。[] seccomp允许进程单向转换为“安全”状态，除了exit（），sigreturn（），read（）和write（）之外，它不能对已经打开的文件描述符进行任何系统调用。如果它尝试任何其他系统调用，内核将使用SIGKILL或SIGSYS [] []终止进程。 从这个意义上说，它不会虚拟化系统的资源，而是将过程与它们完全隔离开来。

centos6的kibana7.1无法启动报错 FATAL  Error: /lib64/libc.so.: version `GLIBC_2.' not found 升级glibc的问题处理

系统：centos6.10_x86_64

# kibana启动不了，报错：[root@:~]# tail -f /var/log/kibana/kibana.stderr

 FATAL  Error: /lib64/libc.so.: version `GLIBC_2.' not found (required by /usr/share/kibana/node_modules/@elastic/nodegit/build/Release/nodegit.node)

解决办法：升级glibc到2.

.原先的系统glibc库的版本是2.，需要升级到2.17版本
