Docker 之 Nginx環境搭建

Nginx 安裝教程

Linux 環境

Linux 中安裝

  • 安裝編譯工具及庫檔案

    yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel
複製程式碼

  • 首先要安裝 PCRE

    PCRE 作用是讓 Nginx 支援 Rewrite 功能

    若提示無wget則安裝（在 Docker 拉取的源 centos 中預設是沒安裝的）

    yum -y install wget
複製程式碼

    進入程式安裝目錄

    cd /usr/local/src/
複製程式碼

    • 下載pcre安裝包

      wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
複製程式碼

    • 解壓安裝包:

      tar -zxvf pcre-8.35.tar.gz
複製程式碼

    • 刪除安裝包

      rm -rf pcre-8.35.tar.gz
複製程式碼

    • 進入安裝包

      cd pcre-8.35
複製程式碼

    • 編譯安裝

      ./configure
make && make install
複製程式碼

    • 檢視pcre版本

      preconv --version
複製程式碼
      [root@de790c02f7b6 pcre-8.35]# preconv --version
GNU preconv (groff) version 1.22.2 with iconv support
複製程式碼

  • 安裝 Nginx

    • 下載安裝包

      wget http://nginx.org/download/nginx-1.6.2.tar.gz
複製程式碼

    • 安裝

       cd nginx-1.8.0
 ./configure --prefix=/usr/local/nginx
 make
 make install
複製程式碼

    • 檢查安裝結果

        /usr/local/nginx/sbin/nginx -v
複製程式碼

Dockerfile 安裝

指令碼

映象

docker build -t env-nginx . docker images docker tag [映象ID] env-nginx:1.0 docker run -i -t -p 80:80 env-nginx:1.0

清空 Nginx Docker

docker rm -f docker container ls -a -q docker rmi -f env-nginx:2.0 docker build -t env-nginx:2.0 . docker run -i -t -p 8001:80 --name nginx --restart=always env-nginx:2.0

執行後執行nginx

配置路由

  • 關閉nginx

    ./nginx -s stop

    xiazhaoyangdeMacBook-Pro:~ xiazhaoyang$ docker ps
