【中文标题】如何在 AWS Elastic Beanstalk 上修改 Nginx 配置【英文标题】:How to amend Nginx config on AWS Elastic Beanstalk 【发布时间】:2015-11-27 18:12:55 【问题描述】:我正在尝试为我的 Elastic Beanstalk 部署修改 Nginx 配置。默认配置是:-
upstream nodejs
server 127.0.0.1:8081;
keepalive 256;
server
listen 8080;
if ($time_iso8601 ~ "^(\d4)-(\d2)-(\d2)T(\d2)")
set $year $1;
set $month $2;
set $day $3;
set $hour $4;
access_log /var/log/nginx/healthd/application.log.$year-$month-$day-$hour healthd;
access_log /var/log/nginx/access.log main;
location /
proxy_pass http://nodejs;
proxy_set_header Connection "";
proxy_http_version 1.1;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
gzip on;
gzip_comp_level 4;
gzip_types text/html text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
我尝试将其他命令添加到位置节点:-
chunked_transfer_encoding off;
proxy_buffering off;
proxy_cache off;
我最初尝试将以下内容添加到我的.ebextensions
:-
files:
"/etc/nginx/conf.d/00_elastic_beanstalk_proxy.conf" :
mode: "000644"
owner: root
group: root
content: |
upstream nodejs
server 127.0.0.1:8081;
keepalive 256;
server
listen 8080;
if ($time_iso8601 ~ "^(\d4)-(\d2)-(\d2)T(\d2)")
set $year $1;
set $month $2;
set $day $3;
set $hour $4;
access_log /var/log/nginx/healthd/application.log.$year-$month-$day-$hour healthd;
access_log /var/log/nginx/access.log main;
location /
proxy_pass http://nodejs;
proxy_set_header Connection "";
proxy_http_version 1.1;
chunked_transfer_encoding off;
proxy_buffering off;
proxy_cache off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
gzip on;
gzip_comp_level 4;
gzip_types text/html text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
但是,在通过 SSH 连接到 EC2 实例时,我可以看到该文件与原始文件没有任何变化。然后我做了一些更多的研究,建议在/etc/nginx/conf.d/00_elastic_beanstalk_proxy.conf
被部署 .ebextensions
文件运行之后。

Nginx config file overwritten during Elastic Beanstalk deployment?
所以我尝试了以下方法:-
files:
"/tmp/deployment/config/#etc#nginx#conf.d#00_elastic_beanstalk_proxy.conf" :
mode: "000755"
owner: root
group: root
content: |
upstream nodejs
server 127.0.0.1:8081;
keepalive 256;
server
listen 8080;
if ($time_iso8601 ~ "^(\d4)-(\d2)-(\d2)T(\d2)")
set $year $1;
set $month $2;
set $day $3;
set $hour $4;
access_log /var/log/nginx/healthd/application.log.$year-$month-$day-$hour healthd;
access_log /var/log/nginx/access.log main;
location /
proxy_pass http://nodejs;
proxy_set_header Connection "";
proxy_http_version 1.1;
chunked_transfer_encoding off;
proxy_buffering off;
proxy_cache off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
gzip on;
gzip_comp_level 4;
gzip_types text/html text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
再次,在通过 SSH 连接到实例时,我可以看到 /tmp/deployment/config/#etc#nginx#conf.d#00_elastic_beanstalk_proxy.conf
或 /etc/nginx/conf.d/00_elastic_beanstalk_proxy.conf
都没有被修改。
所以现在我很困。我有哪些选择?
【问题讨论】:
.ebextensions
格式为 YAML 或 JSON。而且,您的配置格式是 YAML。 YAML 需要正确的缩进。在上面的配置中,缩进看起来是错误的(files:
和 "/etc/nginx/conf.d/00_elastic_beanstalk_proxy.conf" :
不应该在同一个缩进中)。
【参考方案1】:
有效的是编写一个 sed 脚本来更新 00_elastic_beanstalk_proxy.conf
文件(通过搜索和替换)并在 container_command
挂钩处运行所述脚本。
您可以拥有这样的.ebextensions
文件:
files:
/tmp/deployment/custom_mod_nginx.sh:
mode: "000755"
content: |
sed -i 's/proxy_http_version 1.1;/ proxy_http_version 1.1;\n chunked_transfer_encoding off;\n proxy_buffering off;\n proxy_cache off;\n/' /tmp/deployment/config/#etc#nginx#conf.d#00_elastic_beanstalk_proxy.conf
container_commands:
nginx_real_ip:
command: "/tmp/deployment/custom_mod_nginx.sh"
这将创建一个名为custom_mod_nginx.sh
的脚本(你可以使用你想要的名称)。该脚本在 beanstalk 部署配置后执行。
【讨论】:
这是目前唯一可以修改/tmp/deployment/config/#etc#nginx#nginx.conf
文件的解决方案。以上是关于如何在 AWS Elastic Beanstalk 上修改 Nginx 配置的主要内容,如果未能解决你的问题,请参考以下文章
