CentOS7添加系统网络相关参数报错 出现No such file or directory

一、CentOS7添加net.bridge.bridge-nf-call-iptables 出现No such file or directory

  一、添加CentOS7的系统参数报错

　　1、添加/etc/sysctl.conf参数

echo "# bridge" >> /etc/sysctl.conf
echo "net.bridge.bridge-nf-call-iptables = 1" >> /etc/sysctl.conf
echo "net.bridge.bridge-nf-call-ip6tables = 1" >> /etc/sysctl.conf
sysctl -p

　　2、报错如下

# sysctl -p
net.ipv4.ip_nonlocal_bind = 1
net.ipv4.ip_forward = 1
sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-iptables: No such file or directory
sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-ip6tables: No such file or directory

　　3、解决如下

[root@controller01 ml2]#  modprobe br_netfilter
[root@controller01 ml2]#  ls /proc/sys/net/bridge
bridge-nf-call-arptables  bridge-nf-call-iptables        bridge-nf-filter-vlan-tagged
bridge-nf-call-ip6tables  bridge-nf-filter-pppoe-tagged  bridge-nf-pass-vlan-input-dev
[root@controller01 ml2]#  sysctl -p
net.ipv4.ip_nonlocal_bind = 1
net.ipv4.ip_forward = 1
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
