keepalived报错集锦

1.Restarting keepalived (via systemctl):  Job for keepalived.service failed because a configured resource limit was exceeded. See "systemctl status keepalived.service" and "journalctl -xe" for details.

                                                           [FAILED]

keepalived在启动的时候默认是读取/etc/keepalived/keepalived.conf下的配置文件，当我们的配置文件不在这里时。我们就要复制一份配置文件过来过来

解决方法：cp keepalived-1.4.4/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/

2、keepalived+nginx架构：nginx宕机后VIP还在，查看keepalived错误日志发现，但是selinux机制是关闭的：

SELinux is preventing /usr/sbin/keepalived from name_connect access on the tcp_socket port 63781. For complete SELinux messages run: sealert -l e1ae27e5-04c5-42d2-a015-aa5580237c22
