Docker 安装启动Nginx

1.搜索镜像 search
2.下载镜像 pull
3.运行测试

配置文件详解

1.nginx的相关目录

  1. /usr/local/nginx目录是nginx安装成功后，默认生成的目录。
  2. nginx的启动文件在/usr/local/nginx/sbin目录下。
  3. nginx的生效的主配置文件是/usr/local/nginx/conf/nginx.conf

2.nginx配置文件的结构

...            #全局块events {    #events块   ...}http {    #http块    ...       server {    #server块         ...              location [PATTERN]  {   #location块            ...        }        location [PATTERN]  {     #location块            ...        }    }    server {    #server块      ...    }    ...     #http全局块}

3.include子配置文件

在生效的主配置文件中的http{}配置块中，用include包含其他目录的自定义配置文件，并令其生效。
(每次重新配置文件都需要重启nginx服务器或者重新加载配置文件)

worker_processes  1;events {    worker_connections  1024;}http {    include    /www/nginx/*.conf;  # 在http的配置块中配置    include       mime.types;    default_type  application/octet-stream;    sendfile        on;    keepalive_timeout  65;    server {        listen       80;        server_name  localhost;        location / {            root   html;            index  index.html index.htm;        }        error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }    }}

其他目录/www/nginx/*.conf的配置文件：

    server {        listen       80;        server_name  localhost;        location / {            root   html;            index  index.html index.htm;        }        error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }    }

4.配置反向代理和负载均衡(全)

worker_processes  1;events {    worker_connections  1024;}http {    include       mime.types;    default_type  application/octet-stream;    sendfile        on;    keepalive_timeout  65;    # 配置反向代理服务器的ip列表    upstream myserverlist {         server 127.0.0.1:8888 weight=1;    # 负载均衡配置权重（加权轮询）      server 192.168.1.1:9999 weight=1;    # # 负载均衡配置权重（加权轮询）    }    server {        listen       80;        server_name  localhost;        location / {            root   html;            index  index.html index.htm;             # 请求myserverlist 定义的服务器列表            proxy_pass  http://myserverlist ;         }        error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }    }}

5.前端静态资源部署（Server静态详情配置）

server {       listen       80;       server_name  127.0.0.1;       location /prod-api/ {               # proxy_set_header用来重定义发往后端服务器的请求头            proxy_set_header Host $http_host;            proxy_set_header X-Real-IP $remote_addr;            proxy_set_header REMOTE-HOST $remote_addr;            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;            proxy_pass http://localhost:8888/;        }        location / {            root   /www/dist;    # 访问127.0.0.1:80地址的时候，定位到/www/dist文件夹下的首页index.html            try_files $uri $uri/ /index.html;            index  index.html index.htm;        }        #error_page  404              /404.html;        # redirect server error pages to the static page /50x.html        error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }    }
