CentOS内核优化提示：cannot stat /proc/sys/net/bridge/bridge-nf-call-ip6tables: 没有那个文件或目录

临时解决，重启失效

modprobe br_netfilter

为了开机加载上面这个模块

cat > /etc/rc.sysinit << EOF
#!/bin/bash
for file in /etc/sysconfig/modules/*.modules ; do
[ -x $file ] && $file
done
EOF
cat > /etc/sysconfig/modules/br_netfilter.modules << EOF
modprobe br_netfilter
EOF
chmod 755 /etc/sysconfig/modules/br_netfilter.modules
lsmod |grep br_netfilter
