4.开启路由转发
1）添加配置文件 开启网络转发
|
1
|
echo 1 > /proc/sys/net/ipv4/ip_forward
|
2）刷新配置
sysctl -p
5重启keepalived服务并设置开机自启动
1）重启keepalive
|
1
|
systemctl restart keepalived
|
2）设置开机自启动
systemctl enable keepalived
注：如果服务启动不起来，并报错/usr/lib64/perl5/CORE/libperl.so: file too short，那就必须先升级perl，然后在重新安装这些步骤哦！

使用的脚本的命令在sh中有提示
最后在浏览器上访问 vip 192.168.58.12 就可到 192.168.58.128 或者129上的nginx上
