错误提示：Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.
运行 systemctl status nginx.service 提示如下：

Nov 07 16:17:40 ip-172-31-28-177 systemd[1]: Starting A high performance web server and a reverse proxy server...
Nov 07 16:17:40 ip-172-31-28-177 nginx[10083]: nginx: [emerg] could not build server_names_hash, you should increase server_names_hash_bucket_size: 64

网上搜了很久，说是少了一个 ";",但我检查了两次，没有少分号。请高手指教是什么问题？谢谢

you should increase server_names_hash_bucket_size: 64
然后谷歌出的是：
http {
server_names_hash_bucket_size 64;
...
}

可以用 ngingx -t 测试配置文件。

善用 Google: https://github.com/nginxinc/kubernetes-ingress/issues/34

> set server-name-hash-bucket-size: "1024" in the configMap

贴一下 /etc/nginx/nginx.conf 文件和 sudo nginx -t 的运行结果

提示配置文件有错误，你最小化配置文件重启试试！

配置文件出错，对比老的好好看看，有没有用到全角符号之类的

#2 #3 的方法应该可以了吧报错里的重点就是 "you should increase server_names_hash_bucket_size" hash 桶不够，设置成 128

虚拟主机配置文件出错了，可以到 /etc/nginx/sites-enabled 目录下，把里面的软链接文件逐个删除，没删除一个，重启下 nginx ；如果哪个删后，nginx 可以重启成功了，就说明是哪个配置文件出错了，把那个仔细检查下，最后一定记得把删除后的软链接配置文件重新都加上去
