bridge-nf-call-ip6tables is an unknown key異常處理
系統(tǒng)：CentOS 6.5
問題描述：按如下內(nèi)容在/etc/sysctl.conf文件末尾添加后.
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 8181829631
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128

net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.conf.eth0.rp_filter = 1
執(zhí)行/sbin/sysctl -p，出現(xiàn)以下異常：
[root@leo ~]# /sbin/sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0

net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.conf.eth0.rp_filter= 1
異常原因：高亮的3個錯誤依賴于bridge模塊，該模塊如果沒有加載則會現(xiàn)上面的錯誤.
解決方案:加載bridge模塊
[root@leo ~]# modprobe bridge
[root@leo ~]# lsmod|grep bridge
bridge 83177 0
stp 2218 1 bridge
llc 5546 2 bridge,stp
重新執(zhí)行/sbin/sysctl -p，無異常發(fā)生.
