br_netfilter 模块开机自动方法
环境
cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)
在/etc/sysctl.conf中添加:
net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1
执行sysctl -p 时出现:
[root@localhost ~]# sysctl -p sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-ip6tables: No such file or directory sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-iptables: No such file or directory
解决方法:
[root@localhost ~]# modprobe br_netfilter [root@localhost ~]# sysctl -p net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1
重启后模块失效,下面是开机自动加载模块的脚本
在/etc/新建rc.sysinit 文件
cat /etc/rc.sysinit
#!/bin/bash for file in /etc/sysconfig/modules/*.modules ; do [ -x $file ] && $file done
在/etc/sysconfig/modules/目录下新建文件如下
cat /etc/sysconfig/modules/br_netfilter.modules modprobe br_netfilter
增加权限
chmod 755 br_netfilter.modules
重启后 模块自动加载
[root@localhost ~]# lsmod |grep br_netfilter br_netfilter 22209 0 bridge 136173 1 br_netfilter
