如何解决在 Beanstalk nodejs 环境中增加 nginx 的 worker_connections
我正在尝试增加 Beanstalk nodejs 服务器 (Amazon Linux 2) 上 Nginx 的可能 worker_connections
数量。
我按照文档创建了一个包含以下内容的文件 .platform/Nginx/conf.d/proxy.conf
:
worker_rlimit_nofile 65536;
events {
worker_connections 32768;
}
部署时出现错误:
[emerg] "worker_rlimit_nofile" directive is not allowed here in /var/proxy/staging/Nginx/conf.d/proxy.conf
评论这一行时,我仍然得到:
[emerg] "events" directive is not allowed here in /var/proxy/staging/Nginx/conf.d/proxy.conf:3
解决方法
我认为这些是顶级设置,您必须覆盖主 nginx.conf
文件。您可以通过创建 .platform/nginx/nginx.conf
配置文件来完成此操作。在这种情况下,您可以删除 .platform/nginx/conf.d/proxy.conf
。
您可以尝试以下.platform/nginx/nginx.conf
:
# For more information on configuration,see:
# * Official English Documentation: http://nginx.org/en/docs/
# * Official Russian Documentation: http://nginx.org/ru/docs/
user nginx;
worker_processes auto;
worker_rlimit_nofile 65536;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 32768;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 4096;
include /etc/nginx/mime.types;
default_type application/octet-stream;
include /etc/nginx/conf.d/*.conf;
server {
listen 80;
listen [::]:80;
server_name _;
root /usr/share/nginx/html;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
}
如果这不起作用,您可以通过 ssh 进入您的 EB 实例,检查您的 EB 环境的实际默认 nginx.conf
(/etc/nginx/nginx.conf
) 是什么,复制它,并在 {{1 }}。
@marcin 上面的回答是正确的。更新 worker_connections 需要通过 .platform/nginx/nginx.conf
文件进行修改。供其他人参考,截至 2021 年 7 月,AWS 将以下内容用作 Elastic Beanstalk v2 和 Amazon Linux 2 上的 nginx.conf 的默认值:
#Elastic Beanstalk Nginx Configuration File
user nginx;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
worker_processes auto;
worker_rlimit_nofile 131435;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
include conf.d/*.conf;
map $http_upgrade $connection_upgrade {
default "upgrade";
}
server {
listen 80 default_server;
access_log /var/log/nginx/access.log main;
client_header_timeout 60;
client_body_timeout 60;
keepalive_timeout 60;
gzip off;
gzip_comp_level 4;
gzip_types text/plain text/css application/json application/javascript application/x-javascript text/xml application/xml application/xml+rss text/javascript;
# Include the Elastic Beanstalk generated locations
include conf.d/elasticbeanstalk/*.conf;
}
}
只需将上述文件添加到 .platform/nginx/nginx.conf
并将 worker_connections 值修改为所需的值。 AWS docs are lacking on this currently,但我已要求他们进行进一步更新。
