解决nginx警告： nginx: [warn] could not build optimal types_hash, you should increase either types_hash_max_size: 2048 or types_hash_bucket_size: 64; ignoring types_hash_bucket_size

问题描述

某日重启Nginx出现如下告警：

[root@localhost ~]# systemctl status nginx

8月 16 14:16:13 localhost systemd[1]: Starting The nginx HTTP and reverse proxy server...
8月 16 14:16:13 localhost nginx[2116]: nginx: [warn] could not build optimal types_hash, you should increase either types_hash_max_size: 2048 or types_hash_bucket_size: 64; ignoring types_hash_bucket_size
8月 16 14:16:13 localhost nginx[2116]: nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
8月 16 14:16:13 localhost nginx[2116]: nginx: configuration file /etc/nginx/nginx.conf test is successful
8月 16 14:16:13 localhost nginx[2116]: nginx: [warn] could not build optimal types_hash, you should increase either types_hash_max_size: 2048 or types_hash_bucket_size: 64; ignoring types_hash_bucket_size
8月 16 14:16:13 localhost systemd[1]: Started The nginx HTTP and reverse proxy server.

Nginx配置文件也出现上述告警

解决办法

在Nginx.conf的http模块下增加：

types_hash_max_size 4096;

通过Nginx -t不在出现告警，重启Nginx服务也恢复正常。
