在Linux系统上,Keepalived是一款高可用性解决方案,用于IP虚拟主机管理和VRRP协议实现网络冗余。为了保证Keepalived服务在系统启动时自动运行,你需要创建并设置一个开机自启动脚本。以下是基本步骤:
1. **安装Keepalived**:
首先,确保已经安装了Keepalived。如果没有,可以使用包管理器如`apt-get`(对于Debian/Ubuntu)或`yum`(对于CentOS/RHEL)来安装:
```
sudo apt-get update
sudo apt-get install keepalived
```
2. **创建启动脚本**:
在 `/etc/init.d` 目录下(如果不存在,需要创建它),创建一个新的启动脚本文件,例如 `keepalived-startup.sh`:
```bash
nano /etc/init.d/keepalived-startup.sh
```
在打开的编辑器中添加以下内容:
```bash
#!/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
start() {
echo -eq 0 ] && echo "OK" || echo "FAILED"
}
stop() {
echo -n $"Stopping Keepalived: "
killall keepalived
RETVAL="$?"
[ $RETVAL -eq 0 ] && echo "OK" || echo "FAILED"
}
case "$1" in
start)
start
;;
stop)
stop
;;
*)
echo $"Usage: /etc/init.d/keepalived-startup.sh {start|stop}"
exit 1
esac
shift
case "$1" in
restart|force-reload)
stop
start
;;
*)
:;;
esac
exit 0
```
3. **赋予脚本执行权限**:
```
chmod +x /etc/init.d/keepalived-startup.sh
```
4. **配置文件管理**:
- 创建Keepalived的基本配置文件(通常放在 `/etc/keepalived/keepalived.conf`)。
- 确保该文件包含了VRRP组的定义、虚拟IP地址以及其他必要的参数。
5. **设置开机自启动**:
将 Keepalived 启动脚本加入到系统的默认启动流程中:
```bash
sudo update-rc.d keepalived-startup.sh defaults
```
6. **测试脚本**:
最后,你可以手动测试脚本是否能正常启动和停止Keepalived服务:
```bash
sudo service keepalived-startup.sh start
sudo service keepalived-startup.sh stop
```
