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
[root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# cd /yinzhengjie/softwares/dockerfile/web/nginx/ [root@docker101.yinzhengjie.org.cn /yinzhengjie/softwares/dockerfile/web/nginx]# [root@docker101.yinzhengjie.org.cn /yinzhengjie/softwares/dockerfile/web/nginx]# ll total 12 -rwxr-xr-x 1 root root 461 Jan 21 16:37 docker-build.sh -rw-r--r-- 1 root root 1833 Jan 21 16:44 Dockerfile -rw-r--r-- 1 root root 1979 Jan 21 16:31 nginx.conf [root@docker101.yinzhengjie.org.cn /yinzhengjie/softwares/dockerfile/web/nginx]# [root@docker101.yinzhengjie.org.cn /yinzhengjie/softwares/dockerfile/web/nginx]# [root@docker101.yinzhengjie.org.cn /yinzhengjie/softwares/dockerfile/web/nginx]# wget http://nginx.org/download/nginx-1.14.2.tar.gz --2020-01-21 16:53:09-- http://nginx.org/download/nginx-1.14.2.tar.gz Resolving nginx.org (nginx.org)... 95.211.80.227, 62.210.92.35, 2001:1af8:4060:a004:21::e3 Connecting to nginx.org (nginx.org)|95.211.80.227|:80... connected.

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)

二.准备测试数据
1>.模拟打包生产环境代码
[root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# ll total 0 [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# echo "<h1>YinZhengjie's Nginx Web Server</h1>" > index.html [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# echo "<h1>YinZhengjie's Nginx Web Server 2020</h1>" > index2020.html [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# ll total 8 -rw-r--r-- 1 root root 45 Jan 21 17:38 index2020.html -rw-r--r-- 1 root root 40 Jan 21 17:38 index.html [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# tar zcvf code.tar.gz index* index2020.html index.html [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# ll total 12 -rw-r--r-- 1 root root 197 Jan 21 17:38 code.tar.gz -rw-r--r-- 1 root root 45 Jan 21 17:38 index2020.html -rw-r--r-- 1 root root 40 Jan 21 17:38 index.html [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# ll /yinzhengjie/softwares/dockerfile/web/nginx/ total 1004 -rwxr-xr-x 1 root root 461 Jan 21 16:37 docker-build.sh -rw-r--r-- 1 root root 2603 Jan 21 17:34 Dockerfile -rw-r--r-- 1 root root 1015384 Dec 4 2018 nginx-1.14.2.tar.gz -rw-r--r-- 1 root root 1979 Jan 21 16:31 nginx.conf [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# cp code.tar.gz /yinzhengjie/softwares/dockerfile/web/nginx/ [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# cd /yinzhengjie/softwares/dockerfile/web/nginx/ [root@docker101.yinzhengjie.org.cn /yinzhengjie/softwares/dockerfile/web/nginx]# [root@docker101.yinzhengjie.org.cn /yinzhengjie/softwares/dockerfile/web/nginx]# ll total 1008 -rw-r--r-- 1 root root 197 Jan 21 17:39 code.tar.gz -rwxr-xr-x 1 root root 461 Jan 21 16:37 docker-build.sh -rw-r--r-- 1 root root 2603 Jan 21 17:34 Dockerfile -rw-r--r-- 1 root root 1015384 Dec 4 2018 nginx-1.14.2.tar.gz -rw-r--r-- 1 root root 1979 Jan 21 16:31 nginx.conf [root@docker101.yinzhengjie.org.cn /yinzhengjie/softwares/dockerfile/web/nginx]#
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 { } } } [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]#
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 # #******************************************************************** #Author: yinzhengjie #QQ: 1053419035 #Date: 2020-01-18 #FileName： docker-build.sh #URL: http://www.cnblogs.com/yinzhengjie #Description： The test script #Copyright (C): 2020 All rights reserved #******************************************************************** TAG=$1 docker image build -t nginx:${TAG} ./ [root@docker101.yinzhengjie.org.cn /yinzhengjie/softwares/dockerfile/web/nginx]#
4>.编写Dockerfile
[root@docker101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/dockerfile/web/nginx/Dockerfile #******************************************************************** #Author: yinzhengjie #QQ: 1053419035 #Date: 2019-11-25 #Blog: http://www.cnblogs.com/yinzhengjie #Description： YinZhengjie's Nginx Dockerfile #Copyright notice: original works, no reprint!

5>.编译生成nginx镜像

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 nginx make-v0.1-20200121-0846 e8520d2c15ae About an hour ago 590MB <none> <none> 5d81119e1e53 About an hour ago 590MB <none> <none> fd9dcda01aa8 About an hour ago 590MB <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 86cbd7aa982c nginx:make-v0.1-20200121-0846 "nginx" 5 minutes ago Up 5 minutes 443/tcp, 172.200.3.101:8080->80/tcp myNginx [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# docker container inspect -f "{{.NetworkSettings.IPAddress}}" myNginx 172.17.0.2 [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 20480 172.200.3.101:8080 *:* LISTEN 0 128 *:22 *:* LISTEN 0 128 :::22 :::* [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# docker container exec -it myNginx bash [root@yinzhengjie /]# [root@yinzhengjie /]# tail -10f /yinzhengjie/softwares/nginx/logs/access_json.log {"@timestamp":"2020-01-21T11:29:57+00:00","host":"172.17.0.2", '"clientip":"172.200.0.1",' "size":0, '"responsetime":0.000,' '"upstreamtim e":"-",' '"upstreamhost":"-",' '"http_host":"docker101.yinzhengjie.org.cn",' '"uri":"/index.html",' '"domain":"docker101.yinzhengjie.org.cn",' '"xff":"-",' '"referer":"-",' '"tcp_xff":"",' '"http_user_agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.117 Safari/537.36",' '"status":"304"}'{"@timestamp":"2020-01-21T11:30:31+00:00","host":"172.17.0.2", '"clientip":"172.200.0.1",' "size":45, '"responsetime":0.000,' '"upstreamti me":"-",' '"upstreamhost":"-",' '"http_host":"docker101.yinzhengjie.org.cn",' '"uri":"/index2020.html",' '"domain":"docker101.yinzhengjie.org.cn",' '"xff":"-",' '"referer":"-",' '"tcp_xff":"",' '"http_user_agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.117 Safari/537.36",' '"status":"200"}'
当你的才华还撑不起你的野心的时候，你就应该静下心来学习。当你的能力还驾驭不了你的目标的时候，你就应该沉下心来历练。问问自己，想要怎样的人生。
