Description
配置如下：
upstream idmservice {
server 10.13.185.250:28342;
upsync consul-dev.2haohr.com:8500/v1/kv/upstreams/idm-service/ upsync_timeout=6m upsync_interval=500ms upsync_type=consul strong_dependency=off;
upsync_dump_path /etc/nginx/upstreams/dump/idmservice.conf;
include /etc/nginx/upstreams/dump/idmservice.conf;
}
执行nginx -s reload过程中出现文件写入竞争问题
堆栈如下：
