三个节点memcached.service
处于活动状态(正在运行):
[root@ha-node3 my.cnf.d]# systemctl status memcached.service
● memcached.service - memcached daemon

但是在haproxy网站中,三个节点都已关闭。
修改-1
我发现端口Memcache_Servers
中的/etc/haproxy/haproxy.cfg
配置为22122
(我写错了),所以我改为11211
,然后重启haproxy,但仍然不行。
listen Memcache_Servers
bind 45.117.40.168:11211
balance roundrobin
mode tcp
option tcpka

答案 0 :(得分:0)
在决赛中,我发现我的主机中的ip如下:
[root@ha-node1 sysconfig]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.8.101 ha-node1 ha-node1.aa.com
192.168.8.102 ha-node2 ha-node2.aa.com
192.168.8.103 ha-node3 ha-node3.aa.com
45.117.40.168 ha-vhost devops.aa.com
192.168.8.104 nfs-backend backend.aa.com
但在我的/etc/sysconfig/memcached
中,ip之前不是主机ip,所以我在主机中更改为ip,你看到下面的快照:
现在我重新启动memcached和haproxy,它现在正常工作。
