Docker安装nginx

大家好最近正在学习docker。就想写一下笔记供大家参考。今天我们NGINX安装问题。

首先docker是一个容器。它分为主机和宿机。就好比docker中形容的一艘船上有很大多集装箱。船就相当我们的主机，集装箱就相当的我们的宿机。每个宿机都是独立的。里面都有自己的一套系统。在主机中宿机就相当主机中的一个进程。宿机可以共享主机资源。就我们常说的数据的挂载到宿机的相关目录。那我们现在切入正题。

1. 搜索镜像
   docker search nginx

2. 下载镜像
   docker pull nginx

3. 查看镜像

gongzgiyangdeMacBook-Air:www gongzhiyang$  docker images nginx
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               latest              7042885a156a        3 weeks ago         109MB

4. 在使用镜像之前我们要配置一下本地的服务
   创建一系列的文件和目录如下
   这个 NGINX.conf 是主机中当前目录下的nginx.conf挂载到容器的/etc/nginx/nginx.conf

`

nginx.conf 文件摘要

这个就是挂载到容器的目录。
location / {
            root   /www;
            index  index.html index.htm;
        }

6. 使用镜像

docker run  -p 81:81 --name webserver2 -v $PWD/www:/www -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf -v $PWD/logs: /var/log/nginx  -d nginx

命令说明：

• -p 81:81 -p: 端口映射，格式为：主机(宿主)端口:容器端口
  将容器的81端口映射到主机的81端口
• –name webserver2 将容器命名为webserver2
• -v $PWD/www:/www 将主机中当前目录下的www挂载到容器的/www
• $PWD/conf/nginx.conf:/etc/nginx/nginx.conf 主机中当前目录下的nginx.conf挂载到容器的/etc/nginx/nginx.conf
• $PWD/logs: /var/log/nginx 将主机中当前目录下的logs挂载到容器的/var/log/nginx
• $pwd 标示当前的目录

gongzgiyangdeMacBook-Air:docker-www gongzhiyang$ pwd
/Users/gongzgiyang/docker-www

7. 查看运行的容器

gongzgiyangdeMacBook-Air:docker-www gongzhiyang$ docker run -p 81:81 --name mynginx1 -v $PWD/www:/www -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf -v $PWD/logs:/wwwlogs  -d nginx
44370a1b81cc4904a4f955aaf6c0810f1feddf5b05b3d8c7b09b71dc189c1075


gongzgiyangdeMacBook-Air:docker-www gongzhiyang$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                        NAMES

到现在为止就完成了NGINX的搭建，我们在本地就可以控制配置文件和项目文件实现了同步。就聊到这了。谢谢大家。
