1.安装ifenslave
sudo apt-get install ifenslave
可能会遇到mysql依赖错误,查看网址https://askubuntu.com/questions/835628/access-denied-for-user-debian-sys-maint-installing-mysql解决的
具体步骤:
sudo su
root@iqbal: mysql -u root -p
Enter password:
mysql> GRANT ALL PRIVILEGES ON *.* TO 'debian-sys-maint'@'localhost' IDENTIFIED BY '<your password>';
如果出现错误(1819),执行如下命令:
mysql> uninstall plugin validate_password;
Then restart mysql: systemctl restart mysql
修复依赖关系
apt install -f
继续安装sudo apt install ifenslave
2.加载内核支持
sudo vi /etc/modules
写入
loop
lp
rtc
bonding
3.停止网络
sudo systemctl stop networking.service
4.加载内核绑定
sudo modprobe bonding
5.修改接口配置文件
sudo vi /etc/network/interfaces
内容如下:切记写入文件时将备注删除
文件具体可参考如下:
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto enp129s0f0 #enp129s0f0 为网卡名称,ifconfig可以看到
iface enp129s0f0 inet manual
pre-up ifconfig enp129s0f0 hw ether [ac:1f:6b:28:bb:b0](http://ac:1f:6b:28:bb:b0/) #网卡0mac 地址
bond-master bond0
bond-primary enp129s0f0 enp129s0f1
auto enp129s0f1
iface enp129s0f1 inet manual
pre-up ifconfig enp129s0f1 hw ether [ac:1f:6b:28:bb:b1](http://ac:1f:6b:28:bb:b1/) #网卡1 mac物理地址
bond-master bond0
bond-primary enp129s0f0 enp129s0f1
auto bond0
iface bond0 inet static
pre-up ifconfig bond0 hw ether [ac:1f:6b:28:bb:b0](http://ac:1f:6b:28:bb:b0/) #网卡0mac 物理地址
address 192.168.102.31
gateway 192.168.102.1
netmask 255.255.255.0
bond-mode active-backup #主备模式,也可以使用负载模式balance-rr,或者其它:balance-xor,broadcast,802.3ad,
bond-miimon 100
bond-slaves none
dns-nameserver 8.8.8.8 #dns-nameserver
6.重启网卡2种方式
sudo /etc/init.d/networking restart
sudo systemctl restart networking.service
7.查看ip addr
如果bond0网卡状态为state down,此时需要重启服务器,然后再执行命令启动网卡(步骤6)
再查看状态bond0为state up就可以了
单一启动网卡命令:ifconfig enp129s0f1 up
或者 ifup enp129s0f1
