Hi , We're facing an error (nginx: [emerg] host not found in resolver "run" in /etc/nginx/nginx.conf) even simple form of container run command. the command that we run is "docker run -d -p 80:80 --name nginx blacklabelops/nginx" any suggestion ? Thanks Author pqantcommentedNov 13, 2017 Collaborato...
Docker 搭建 nginx 出现“host not found in upstream”错误,因启动顺序或更新致部分 host 不存在。可将 upstream 设为变量并设置 resolver ,如 location /test 中 resolver 127.0.0.11 10s ,set $ht docker-h...
nginx: [emerg] host not found in resolver "192.168.1.1 " in /opt/tengine/conf/nginx.conf:124
如果proxy_pass的URL里面包含变量，那么nginx就使用内置的resolver，而这个内置的resolver无法解析docker swarm service的地址。使用resolver指令，让它指向docker swarm的内置DNS地址，这样就可以解析swarm service的地址了。127.0.0.11是docker swarm的内资DNS server，可以用来解析swarm service地址。另外一般建...
nginx: [emerg] host not found in upstream "demo.com.cn" in /usr/local/openresty/nginx/conf/nginx.conf:95 resolver 怎么办了,这下nginx的resolver指定就派上用场了。在A,B机器上查看他们的dns ➜ ~ cat /etc/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by reso...
resolver指令说明见下表。 注意:解析 DNS后,通过 set $ upstream_ host test2. zhe800. com的方式,将获取的 IP地址再赋值给 proxy_ pass,这是为了让 Nginx重新去解析 DNS中的 IP地址。利用 valid的配置,可以减少 DNS的解析次数,从而提高请求的效率。当然对 DNS缓存时间的控制也要有度,避免出现 DNS切换 IP地...
nginx: [emerg] host not found in upstream "" in /path/nginx/conf/nginx.conf:110 (3)proxy_pass + resolver(变量设置域名) server { listen 80; server_name localhost; resolver 114.114.114.114; location /foo { set $foo ; proxy_pass http://$foo; ...
第一种 在/etc/hosts中添加域名对应的IP,或者直接在proxy_pass处配置IP 117.118.12.2 XXXXX.XXXXXX.com 另一种: 不直接在proxy_pass后写域名,而通过变量的方式配置,如下: set$targethttps://www.xxx.com; proxy_pass$target; 除了上面的配置之外,还要在server属性的平行域下使用resolver指令,如下 ...
http { resolver 8.8.8.8 8.8.4.4 valid=300s; upstream backend { server backend1.example.com; server backend2.example.com; } server { listen 80; location / { proxy_pass http://backend; } } } 通过以上步骤,你应该能够定位并解决“nginx: [emerg] host not found in upstream”错误。如果问题...
nginx 通过 proxy_pass 和 upstream server 通信的时候需要手动指定 resolver。某些时候 DNS 解析失败就会出现这个错误: domain.com could not be resolved. 可以指定多个 DNS 并重置域名 TTL 延长 nginx 解析缓存来保障解析成功率: resolver 223.5.5.5 223.6.6.6 1.2.4.8 114.114.114.114 valid=3600s; ...
