更改nginx conf文件

Question

我安装了openresty alpine docker镜像并安装了conf.d在其中定义服务器。很好。

接下来，我要更改nginx.conf并设置worker_process=auto。但是worker_processes是在nginx.conf中定义的。我尝试将Docker-compose文件中的nginx.conf卷挂载为：

volumes:
 -  ./conf.d:/etc/nginx/conf.d  
 -  ./conf/nginx.conf:/usr/local/openresty/nginx/conf/nginx.conf

但是，它会在nginx.conf中创建目录./conf

如何安装/修改nginx.conf？

Answer 1

如果要更新nginx根配置，则使用错误的Docker目录挂载它。

Nginx配置文件

  

Docker工具会安装自己的nginx.conf文件。如果你想   直接覆盖它，您可以将其替换为自己的Dockerfile或通过   批量绑定安装。

     

对于Linux映像，nginx.conf的指令包括   /etc/nginx/conf.d/*.conf;所以那所有的nginx配置   目录将包括在内。默认虚拟主机配置具有   原始的OpenResty配置并复制到   /etc/nginx/conf.d/default.conf。

docker run -v /my/custom/conf.d:/etc/nginx/conf.d openresty/openresty:alpine

第二件事，最好使用绝对路径进行安装。

docker run -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf openresty/openresty:1.15.8.2-1-alpine

或

docker run -v abs_path/nginx.conf:/etc/nginx/nginx.conf openresty/openresty:1.15.8.2-1-alpine

Openresty配置：

docker run -v $PWD/conf/nginx.conf:/usr/local/openresty/nginx/conf/nginx.conf openresty/openresty:1.15.8.2-1-alpine

您应该挂载确切的文件，否则它将破坏容器。

这是/usr/local/openresty/nginx/conf/nginx.conf

的默认配置

# nginx.conf  --  docker-openresty
#
# This file is installed to:
#   `/usr/local/openresty/nginx/conf/nginx.conf`
# and is the file loaded by nginx at startup,
# unless the user specifies otherwise.
#
# It tracks the upstream OpenResty's `nginx.conf`, but removes the `server`
# section and adds this directive:
#     `include /etc/nginx/conf.d/*.conf;`
#
# The `docker-openresty` file `nginx.vh.default.conf` is copied to
# `/etc/nginx/conf.d/default.conf`.  It contains the `server section
# of the upstream `nginx.conf`.
#
# See https://github.com/openresty/docker-openresty/blob/master/README.md#nginx-config-files
