ubuntu下配置nginx+keepalived做HA(续)

作者注：继上篇中没有测试，由于初涉及相关技术，下面测试中的问题记录一下，主要将通过/var/log/messages中的日志来。

问题1：Sep 18 22:20:23 ubuntu Keepalived_vrrp: IPVS: Can't initialize ipvs: Permission denied (you must be root)
解决办法：直接su至root用户，启动keepalived，可快速解决问题。

问题2：Sep 19 02:57:51 ubuntu Keepalived_healthcheckers: IPVS: Can't initialize ipvs: Protocol not available
解决办法：由于没有安装或没有启用ipvs功能，本人系统中没有启用ipvs。
