这个错误信息显示 keepalived 在启动后立即停止了。通常,这可能是由于配置文件中存在错误引起的。
建议检查 keepalived 的配置文件,以确保其语法正确且没有任何错误。您可以通过在命令行中运行以下命令来检查配置文件语法:
```
keepalived -t -f /data/keepaliveds/keepalived.conf
```
如果存在任何语法错误,则会在命令行中输出错误消息。在修复错误后,再次尝试启动 keepalived。
另外,您可以尝试在命令行中手动启动 keepalived,以便更好地了解问题所在。例如,尝试使用以下命令手动启动 keepalived:
```
keepalived -D -f /data/keepaliveds/keepalived.conf
```
这将在后台启动 keepalived 并将其配置文件设置为 /data/keepaliveds/keepalived.conf。如果 keepalived 在启动时遇到任何错误,则会在命令行中输出错误消息。

keepalive双活情况下 /etc/keepalived/keepalived.conf配置示例
Keepalived是一个开源的高可用软件包,它主要用于在服务器集群中提供冗余服务,通过VRRP(Virtual Router Redundancy Protocol)协议实现网络服务的负载均衡和故障切换。当配置keepalived以支持双活模式时,`/etc/keepalived/keepalived.conf` 文件会包含几个关键部分,包括虚拟路由器(VR),VRRP组定义,以及服务和监视器设置。
以下是一个简单的`keepalived.conf` 配置示例:
```conf
vrrp_script chk_mysql {
script "/usr/local/bin/check_mysql.sh"
interval 2
weight 2
}
virtual_router_id 51
vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_ipaddress {
192.168.1.100/24
}
authentication {
auth_type PASS
auth_pass your_password
}
virtual_router_mac MAC_ADDRESS
priority 100
notify_script chk_mysql
}
! Configuration for the secondary server (add this block and change MASTER to BACKUP)
vrrp_instance VI_1 {
state BACKUP
interface eth0
virtual_ipaddress {
192.168.1.100/24
}
...
}
```
- `vrrp_script`: 定义了一个检查脚本,比如检查MySQL服务是否运行正常。
- `virtual_router_id`: 每个VRRP实例的唯一标识符。
- `vrrp_instance`: 每个服务的实例,定义了主备状态、网络接口、VIP(虚拟IP地址)、认证方式(如果启用)和优先级。
- `notify_script`: 设置在状态改变时执行的脚本,如上面的`chk_mysql`。
- `state MASTER` 或 `state BACKUP`: 指定当前节点是主节点还是备节点。
请确保替换`eth0`为实际的网络接口,`MAC_ADDRESS`为网卡的MAC地址,`your_password`为指定的认证密码。在实际环境中,可能还需要配置监控策略、心跳间隔、网络策略等其他细节。
相关问题:
1. Keepalived如何通过VRRP实现双活?
2. 何时需要使用`auth_pass`字段?
3. 如何在备份节点上配置相同的服务?
linux配置内核支持netlink,Linux:编译安装keepalive:/usr/include/netlink/netlink-kernel.h:193:2: error: unknown t...
这个错误提示是因为缺乏netlink的头文件,需要先安装libnl-devel包。
你可以使用以下命令在CentOS系统上安装:
```
sudo yum install libnl-devel
```
在Ubuntu/Debian系统上安装:
```
sudo apt-get install libnl-3-dev libnl-route-3-dev
```
完成安装后,重新编译安装keepalive即可。
