keepalived 添加ipv6配置

对于keepalived的IPv6配置，你可以按照以下步骤进行操作：

1. 确保你的系统已经正确地配置了IPv6网络，并且网络接口已经获得了IPv6地址。

2. 打开keepalived配置文件，通常位于/etc/keepalived/keepalived.conf。

3. 在配置文件中找到你想要使用IPv6的虚拟IP（VIP）段落。它通常以vrrp_instance开头，后面跟着一个唯一的实例名称。

4. 在该段落中，添加下面的配置行以启用IPv6支持：

   use_ipv6

5. 然后，为IPv6 VIP添加以下配置行：

   virtual_ipaddress {
       ipv6address
   }

其中，ipv6address是你想要使用的IPv6 VIP地址。

6. 最后，保存并关闭配置文件。

7. 重新加载keepalived服务以使更改生效。你可以使用以下命令：

   sudo systemctl reload keepalived

完成这些步骤后，keepalived将使用IPv6配置来管理虚拟IP（VIP）。请确保在进行任何更改之前备份keepalived配置文件，以防止意外情况发生。

keepalived配置ipv6

Sure, I can assist you with configuring Keepalived for IPv6. Here's an example configuration for Keepalived using IPv6 addresses:

1. Install Keepalived:

   sudo apt-get install keepalived

2. Create a Keepalived configuration file, such as `/etc/keepalived/keepalived.conf`, and add the following content:

   global_defs {
       router_id LVS_DEVEL
   }

   vrrp_script chk_heartbeat {
       script "/etc/keepalived/heartbeat.sh"
       interval 2
       weight -20
       fall 3
       rise 2
   }

   vrrp_instance VI_1 {
       state MASTER
       interface eth0
       virtual_router_id 51
       priority 101
       advert_int 1
       authentication {
           auth_type PASS
           auth_pass YourPassword
       }
       virtual_ipaddress {
           ::1/64 dev eth0
       }
       track_interface {
           eth0
       }
       notify /etc/keepalived/notify.sh
   }

3. Configure the `chk_heartbeat` script (`/etc/keepalived/heartbeat.sh`) to monitor the health of the virtual IP:

   #!/bin/bash
   if ! ip addr show dev eth0 | grep -q "::1"; then
       exit 1
   fi
   exit 0

4. Configure the `notify` script (`/etc/keepalived/notify.sh`) to handle failover events (optional):

   #!/bin/bash
   if [ "$1" = "MASTER" ]; then
       # Add your custom actions for becoming the master node here
       echo "Became MASTER" >> /var/log/keepalived.log
   elif [ "$1" = "BACKUP" ]; then
       # Add your custom actions for becoming the backup node here
       echo "Became BACKUP" >> /var/log/keepalived.log
   elif [ "$1" = "FAULT" ]; then
       # Add your custom actions for handling faults here
       echo "FAULT" >> /var/log/keepalived.log
   fi

5. Make the scripts executable:

   sudo chmod +x /etc/keepalived/heartbeat.sh
   sudo chmod +x /etc/keepalived/notify.sh

6. Start Keepalived:

   sudo systemctl start keepalived

This configuration sets up Keepalived in master mode (`state MASTER`) with a virtual IPv6 address (::1/64) on the `eth0` interface. Remember to replace `YourPassword` with your desired authentication password.

Note: This configuration example assumes you have the `eth0` interface configured with an appropriate IPv6 address range. Adjust the configuration based on your network setup.

keepalived ipv6

要在keepalived中添加IPv6地址类型的虚拟IP（VIP），你需要进行以下步骤：

1. 在host1上修改keepalived.conf文件，使用vim编辑器打开该文件：`vim /etc/keepalived/keepalived.conf`
2. 在vrrp_instance部分添加以下配置：

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    priority 101
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        2001:fecc:0:622::a/64 #添加IPv6地址
    }
}

3. 保存并关闭文件。

接下来，在host2上进行以下配置：

1. 使用vim编辑器打开keepalived.conf文件：`vim /etc/keepalived/keepalived.conf`
2. 在vrrp_instance部分添加以下配置：

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    priority 99
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        172.28.23.100 #保留原有的IPv4地址
    }
}

3. 保存并关闭文件。

这样，你就成功地在keepalived中添加了IPv6地址类型的虚拟IP（VIP）。
