redis sentinel 故障

Veröffentlicht am von

同事把sentinel monistor mymaster 的ip给改了,造成无法获取sentinel错误.

PHP Redis客户端报错如下:

PSRedis\Exception\ConnectionError: All sentinels are unreachable in /home/xxxx/vendor/jamescauwelier/psredis/lib/PSRedis/MasterDiscovery.php:153

用netstat检查端口情况
sudo netstat -tulpn
返回

原因是把sentiel ip从127.0.0.1 改为某个192的ip了. 改回来后,重启sentinel服务.问题解决.

sudo service redis-sentinel restart
