内核不符合报错

docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "process_linux.go:301: running exec setns process for init caused \"exit status 23\"": unknown.

在遇到这个问题,请检查你的系统版本号这里贴出Ubuntu解决方案
apt-get install --install-recommends linux-generic-lts-xenial

无法打开keepalived设置的ip

 这个问题首先检查自己的配置文件,下面贴下正确的主机代码:

interval 2
weight -5
fall 3
rise 2
}

vrrp_instance VI_1 { state MASTER interface eth0 virtual_router_id 51 priority 101 advert_int 2 authentication { auth_type PASS auth_pass 1111 } virtual_ipaddress { 10.211.55.8 } track_script { chk_nginx } }

> 这里是副机代码:   

interval 2
weight -5
fall 3
rise 2

}

vrrp_instance VI_1 { state BACKUP interface eth0 virtual_router_id 51 priority 100 advert_int 2 authentication { auth_type PASS auth_pass 1111 } virtual_ipaddress { 10.211.55.8 } track_script { chk_nginx } }

**注意我这里的主机ip为 :10.211.55.6 ;副机为:10.211.55.7;虚拟的ip是:10.211.55.8**
