#sudo ufw disalbe

#sudo systemctl disalbe ufw

#sudo apt-get upgrade -y && apt-get update -y

#sudo apt-get install net-tools ntp make gcc libssl-dev openssl -y

#sudo cd /usr/src

#sudo tar -xf keepalived-2.2.4.tar.gz

#sudo cd keepalived-2.2.4/

#sudo ./configure //编译

#sudo make

#sudo make install

#sudo mkdir /etc/keepalived

#sudo cp /usr/local/etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf //根据模板修改配置文件

#sudo vim /etc/keepalived/keepalived.conf

代码语言：shell复制

#sudo cp /usr/src/keepalived-2.2.4/keepalived/keepalived.service /usr/lib/systemd/system/keepalived.service

#keepalived -t //测试keepalived配置

#sudo systemctl start keepalived.service

#sudo systemctl enable keepalived.service

使用命令验证

#systemctl status keepalived.service

#hostname -I //查看虚拟IP在哪个节点上

#ip a //查看网卡的IP

bash指令 bash apt-get http tcp/ip
