一台服务器上的 nginx 下可能跑着很多项目，如果把很多项目都写到同一个配置文件里 ，会导致后期难以查看与管理。

默认配置文件

路径：/etc/nginx/nginx.conf

http {

    server {
        location / {
            root   /usr/share/nginx/dist;
            index  index.html index.htm;
        }      
    }

	##
	# Basic Settings
	##

	sendfile on;
	tcp_nopush on;
	tcp_nodelay on;
	keepalive_timeout 65;
	types_hash_max_size 2048;
	# server_tokens off;

	# server_names_hash_bucket_size 64;
	# server_name_in_redirect off;

	include /etc/nginx/mime.types;
	default_type application/octet-stream;

	##
	# SSL Settings
	##

	ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3; # Dropping SSLv3, ref: POODLE
	ssl_prefer_server_ciphers on;

	##
	# Logging Settings
	##

	access_log /var/log/nginx/access.log;
	error_log /var/log/nginx/error.log;

	##
	# Gzip Settings
	##

	gzip on;

	# gzip_vary on;
	# gzip_proxied any;
	# gzip_comp_level 6;
	# gzip_buffers 16 8k;
	# gzip_http_version 1.1;
	# gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

	##
	# Virtual Host Configs
	##

	## 多项目配置文件
	include /etc/nginx/conf.d/*.conf;
	include /etc/nginx/sites-enabled/*;
}

如果直接在 nginx.conf 文件中添加，配置文件会显得比较臃肿且不好维护。此时可以通过 include 的方式，为每个服务建立 nginx 的配置文件，这样也便于后期维护。

在 /etc/nginx/conf.d/ 目录下新建配置文件 ecs.conf

touch ecs.conf

ecs.conf

路径：/etc/nginx/conf.d/ecs.conf

server {
        listen    90;

		access_log /var/log/nginx/accessecs.log;
		error_log /var/log/nginx/errorecs.log;

        location / {
        	# 代码打包路径
            root  /usr/share/nginx/ecs/;
            index  index.html index.htm;
            # 必写 不然会404
            try_files $uri $uri/ /index.html;
        }
}

测试配置文件中是否存在语法错误

nginx -t

重新加载配置文件

nginx -s reload
