Docker安装Nginx（配置SSL证书）

1.下载Nginx镜像

# 拉取镜像
docker pull nginx
# 查询镜像
docker images

2.创建配置文件

创建挂载目录

mkdir -p /home/nginx/conf.d
mkdir -p /home/nginx/config
mkdir -p /home/nginx/html
mkdir -p /home/nginx/logs
mkdir -p /home/nginx/ssl

启动容器将配置文件复制到宿主机目录中

# 启动容器
docker run --name nginx -p 80:80 -d nginx
# 复制容器配置文件
docker cp nginx:/etc/nginx/nginx.conf /home/nginx/config/
docker cp nginx:/etc/nginx/conf.d /home/nginx
docker cp nginx:/usr/share/nginx/html /home/nginx

停止容器并删除

docker stop nginx
docker rm nginx

3. 修改配置文件

前置条件：

1，域名DNS解析,

2，SSL证书放置到/home/nginx/ssl目录下

3，服务器防火墙指定ip的443, 80 端口正常开启

因为/home/nginx/config/nginx.conf中：include引入了/etc/nginx/conf.d/*.conf

故直接对 /home/nginx/conf.d/default.conf 进行配置

server {
	# https 监听端口
    listen 443 ssl;
    # 监听域名
    server_name xxx.com;
    root /var/www/xxx.com;
    index index.html index.htm;
    # 引入证书
    ssl_certificate  /etc/nginx/ssl/xxx.com.pem;
    ssl_certificate_key /etc/nginx/ssl/xxx.com.key;
    ssl_session_timeout 5m;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;

	# 默认80端口转发
    location / {
       proxy_pass   http://127.0.0.1:18080/;
    }
	
	# 域名后缀转发https:xxx.com/xxx
    location /xxx/ {
       proxy_pass   http://127.0.0.1:8801/;
       proxy_set_header X-Forwarded-Scheme  http;
       proxy_redirect off;
       proxy_set_header Host $host:$server_port;
       proxy_set_header X-Real_IP $remote_addr;
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       proxy_set_header X-Forwarded-Host $server_name;
    }

}
server {
	# https 监听端口
    listen 80;
    # 监听域名
    server_name xxx.com;
    #rewrite ^(.*)$ https://$host$1 permanent;
    rewrite ^(.*) https://$server_name$1 permanent;
}

4.启动Nginx 容器

这里的Nginx与转发目标在一个服务器上，故直接采用host模式

如果不在一个服务器上，可自行将 --net=host 替换为http和https端口映射 -p 443:443 -p 80:80

docker run --name nginx --net=host \
 -v /home/nginx/html:/usr/share/nginx/html \
 -v /home/nginx/config/nginx.conf:/etc/nginx/nginx.conf/ \
 -v /home/nginx/conf.d:/etc/nginx/conf.d \
 -v /home/nginx/logs:/var/log/nginx/ \
 -v /home/nginx/ssl:/etc/nginx/ssl/ \
 --privileged=true \
 -d --restart=always nginx
