Docker安裝nginx以及配置域名對應目錄

1.安裝Docker,若是已經安裝能夠跳過此步驟

yum install docker

啓動docker服務

systemctl start docker

2.使用docker pull命令從docker hub下載最新版本的nginx鏡像

docker pull nginx

3.在宿主機下新建三個目錄:www,logs,conf分別用來映射nginx容器的項目目錄,日誌目錄,配置文件

mkdir /data/nginx
cd /data/nginx
mkdir www logs conf

4.使用nginx鏡像建立一個nginx容器

docker run -d -p 80:80 --name nginx-web \
-v /data/nginx/www:/usr/share/nginx/html \
-v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
-v /data/nginx/logs:/var/log/nginx nginx

-v:將宿主機目錄或者文件掛載到容器對應的目錄或者文件

-d:守護態(後臺)運行容器

-p:將容器的端口映射到主機的端口,前面80是宿主機端口,後面的80是容器端口

--name:命名容器

5.在/data/nginx/conf下新建nginx.conf配置文件

touch /data/nginx/conf/nginx.conf

6.配置nginx.conf文件

假如咱們有兩個項目分別在/data/nginx/www/demo1和/data/nginx/www/demo2下,對應的域名爲demo1.diandi.com和demo2.diandi.com

user  nginx;
worker_processes  1;
error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;
events {
    worker_connections  1024;
}
http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;
    sendfile        on;
    keepalive_timeout  65;
    gzip  on;
    server {
        listen       80;
        server_name  demo1.diandi.com;
        location / {
            root   /usr/share/nginx/html/demo1;
            index  index.html;
        }
    }

    server {
        listen       80;
        server_name  demo2.diandi.com;
        location / { 
            root   /usr/share/nginx/html/demo2;
            index  index.html;
        }   
    } 
}

由於咱們宿主機的/data/nginx/www目錄已經代理了容器的/usr/share/nginx/html目錄因此root參數/usr/share/nginx/html實際目錄是/data/nginx/www

7.重啓容器

docker restart nginx-web
