我在web服务器上有一个haproxy的体系结构,它是路由到从服务器的,在那里我通过postgre使用pgbouncer。 HAPoxy配置:HAProxy + pgbouncer服务器意外关闭了连接
global
log 127.0.0.1 local1 debug
user haproxy
group haproxy
defaults
log global
retries 3
timeout connect 1s
timeout server 20m
timeout client 20m

server pgsql-1 10.5.8.14:6432 check
server pgsql-2 10.5.8.21:6432 check
Pgbouncer配置是默认的。 第一个问题,pgsql-check不起作用。 pgboucer.log:
2016-11-23 12:47:37.805 17068 WARNING C-0x23bb760: (nodb)/(nouser)@10.5.8.13:48898 Pooler Error: No such database: postgres

但最大的问题是,一段时间后,我已经在我的网站(Yii2)得到了许多错误。日志:
2016-11-22 16:37:42 [10.5.33.135][-][-][error][application] SQLSTATE[08006] [7] server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request. in file /var/www/copy-search/vendor/yiisoft/yii2/db/Connection.php on line 547
我有这种感觉,haproxy只是打破了会议。
