故障二

Problem: The security parameters in the kernel do not meet the minimum requirements (see above).
Recommendation: Perform operating system specific instructions to update the kernel parameters, namely BIT_SIZE and noexec_user_stack.

解决办法：

    修改参数/etc/sysctl.conf

net.ipv4.ip_local_port_range = 1024 65000

    保存后执行 sysctl -p   生效
