keepalived实现高可用

准备：

1、A-centos(192.168.6.177)  端口为9898的服务

2、B-ubuntu(192.168.6.182)  端口为9898的服务

3、keepalived安装包https://www.keepalived.org/software/keepalived-1.4.0.tar.gz

https://blog.youkuaiyun.com/duguduchong/article/details/8699774       gcc套装没安装的错误

https://blog.youkuaiyun.com/xiaoborui20110806/article/details/42494669   openssl错误

我遇到的错误和https://blog.youkuaiyun.com/zsg88/article/details/76690847不一样，但是可以参考

我发现报错信息中提示：

Unable to find configuration file /etc/keepalived/keepalived.conf (glob returned 3)

所有我执行了以下命令：

mkdir /etc/keepalived/

 cp  /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf

 

systemctl start keepalived.service

systemctl status keepalived.service

然后keepalived服务就运行起来了
