报错信息 WARNING: IPv4 forwarding is disabled. Networking will not work.

起因是Jenkins半夜拨测的时候不断发出电话告警,一开始以为是生产业务出现问题,火急火燎的登陆上去看,重试后发现是Jenkins连接不上服务器了。报错信息为:
"WARNING: IPv4 forwarding is disabled. Networking will not work."
解决方法:
# 向配置文件 /etc/sysctl.conf 中追加如下内容,如果已经存在则把值改为1 (0表示禁止进行IP转发,1表示IP转发功能已经打开,系统初始状态下默认是关闭的。)
net.ipv4.ip_forward=1
# 重启网络
systemctl restart network
# 验证
sysctl net.ipv4.ip_forward
故事后续:原来是昨晚压测的运维小哥接口数据压不上去,在网上百度后一顿操作猛如虎,把linux内核参数配置改了。
