一.下载nginx的安装包

1>.打开nginx官网,找到最新稳定版下载即可(http://nginx.org/en/download.html)

2>.下载nginx安装包

3>.属性编译安装nginx的步骤(如果你不清楚nginx的编译步骤请估计写不出来Dockerfile的,因此你得了解nginx的编译安装步骤,不熟悉的没关系,看一下我之前的笔记即可,熟悉的同学跳过该步骤)

2>.编写nginx的配置文件

[root@docker101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/dockerfile/web/nginx/nginx.conf 
user nginx;
worker_processes auto;

#错误日志也应该指定到咱们编译安装的nginx目录中
error_log /yinzhengjie/softwares/nginx/logs/error.log;

pid /run/nginx.pid;

#Docker最终运行Nginx建议大家把后台进程关闭,默认是"on".
daemon off;

events {
    worker_connections 1024;
}

http {
    #自定义Nginx的日志格式
    log_format my_access_json '{"@timestamp":"$time_iso8601",' 
                               '"host":"$server_addr",' 
                          '"clientip":"$remote_addr",' 
                           '"size":$body_bytes_sent,' 
                          '"responsetime":$request_time,' 
                          '"upstreamtime":"$upstream_response_time",' 
                          '"upstreamhost":"$upstream_addr",' 
                          '"http_host":"$host",' 
                          '"uri":"$uri",' 
                          '"domain":"$host",' 
                          '"xff":"$http_x_forwarded_for",' 
                          '"referer":"$http_referer",' 
                          '"tcp_xff":"$proxy_protocol_addr",' 
                          '"http_user_agent":"$http_user_agent",' 
                          '"status":"$status"}';
   #同理,我们将访问日志也放到咱们编译安装nginx的目录中             
    access_log /yinzhengjie/softwares/nginx/logs/access_json.log my_access_json;

    sendfile            on;
    keepalive_timeout   65;
    include       mime.types;
    default_type  text/html;
    charset utf-8;

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;

        #别忘记修改站点代码的根目录也要指定到咱们编译安装nginx的目录中哟~
        root         /yinzhengjie/softwares/nginx/html;
        location / {
        }
        error_page 404 /404.html;             
        location = /40x.html {
        }
        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
        }
    }
}

3>.编写快速编译docker的脚本(我这里就是抛砖引玉了,你可以自行优化)

[root@docker101.yinzhengjie.org.cn /yinzhengjie/softwares/dockerfile/web/nginx]# cat docker-build.sh 
#!/bin/bash

#除了安装编译nginx的依赖的安装包外,还可以将一些常用的命令工具也安装上
#类似于这样的安装命令(或者经常改动相对较小的命令)应该尽量往前写,这样在多次编译时就不会重复执行了(因为默认会使用缓存),从而提升编译效率.

三.验证编译版本的nginx镜像

1>.运行容器

[root@docker101.yinzhengjie.org.cn ~]# docker image ls
REPOSITORY          TAG                       IMAGE ID            CREATED             SIZE

<none>              <none>                    896b954fd6d4        About an hour ago   590MB
<none>              <none>                    88d854efd276        About an hour ago   589MB
<none>              <none>                    252190d9a459        2 hours ago         589MB
centos              centos7.6.1810            f1cb7c7d58b7        10 months ago       202MB
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# docker container run -it --rm -p 172.200.3.101:8080:80 --name myNginx --hostname yinzhengjie nginx:make-v0.1-20200121-0846       #运行容器后会阻塞在当前终端,需要再开启一个终端连接该容器,如下图所示。

2>.客户端访问时最好先连接容器查看日志记录

[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# docker container ls
CONTAINER ID        IMAGE                           COMMAND             CREATED             STATUS              PORTS                                 NAMES
