docker 使用 nginx 并配置域名

一、docker 安装nginx

1、搜索nginx 镜像
docker search nginx
2、拉取nginx镜像
docker pull nginx:latest
3、运行镜像
docker run -d --name nginx -p 80:80 -p 443:443 nginx:latest
4、拷贝 nginx容器中的文件到主机目录
docker cp nginx:/etc/nginx/nginx.conf /usr/local/nginx/
docker cp nginx:/etc/nginx/conf.d /usr/local/nginx/conf/
docker cp nginx:/usr/share/nginx/html /usr/local/nginx/html
docker cp nginx:/var/log/nginx/ /usr/local/nginx/logs/
5、停止并删除容器
docker stop nginx
docker rm nginx
6、重启nginx
docker run -d  --name nginx -p 80:80 -p 443:443 -v /usr/local/nginx/nginx.conf:/etc/nginx/nginx.conf -v /usr/local/nginx/logs:/var/log/nginx -v /usr/local/nginx/html:/usr/share/nginx/html -v /usr/local/nginx/conf:/etc/nginx/conf.d  --privileged=true     -e TZ=Asia/Shanghai nginx:latest
7、检测nginx是否启动成功

可以查看log

docker logs nginx

可以直接访问查看 http://ip，出现这个就是启动成功

二、nginx配置转发多个端口

1、docker启动容器后，在挂载出来的nginx里找到nginx.conf

2、或者进入容器，用指令修改配置文件

此时如果报错

如果是基于Debian或Ubuntu的系统，可以使用

sudo apt-get install vim

。

如果是基于Red Hat的系统，可以使用

sudo yum install vim

或

sudo dnf install vim

如果是macOS，可以使用

brew install vim

编辑完 按esc 输入指令:wq 即可

3、配置文件

user nginx;
worker_processes auto;

error_log /var/log/nginx/error.log notice;
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;
 #tcp_nopush     on;

keepalive_timeout  65;

#gzip  on;

include /etc/nginx/conf.d/*.conf;

server {
listen 80;
server_name localhost;

     location / {
         root   /usr/local/nginx/html;
         index  login.html index.htm;
     }

实例一的前端页面，主要root 要换成alias

     location /web1 {

多个前端项目，需要使用alias

         alias   /usr/local/nginx/html/web1 ;
         index  login.html index.htm;
     }

实例二的前端页面

     location /web2 {
         alias   /usr/local/nginx/html/web2;
         index  login.html index.htm;
     }

实例一的后端配置，主要看proxy_pass

      location  /java1/ {

        proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header Host $http_host;

        proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection "upgrade";
         proxy_read_timeout 3600s;
                     proxy_pass  http://ip:port1/;
     }
     location  /java2/ {

        proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header Host $http_host;

        proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection "upgrade";
         proxy_read_timeout 3600s;
                     proxy_pass  http://ip:port2/;
     }

}
}

4、配置后重启nginx
docker restart nginx
5、登入项目测试内部转发是否成功，注：各个容器都有不同的ip，不能用127.0.0.1

三、配置域名

1、首先去申请域名，拿到ssl证书，在挂在出来的nginx路径下创建一个cert文件夹，复制进去

2、将证书复制到容器里
docker cp /usr/local/nginx/cert nginx:/etc/nginx/
3、修改配置文件

user nginx;
worker_processes auto;

error_log /var/log/nginx/error.log notice;
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;
 #tcp_nopush     on;

keepalive_timeout  65;

#gzip  on;

include /etc/nginx/conf.d/*.conf;

server {
     listen 80;
     server_name xxx.xxx.com; # 你的域名
     return 301 https://$server_name$request_uri; # 重定向到HTTPS
  }
 server {
     listen 443 ssl;
     server_name  xxx.xxx.com;

    ssl_certificate /etc/nginx/cert/xxx.xxx.com.pem; # SSL证书文件路径
     ssl_certificate_key /etc/nginx/cert/xxx.xxx.com.key; # SSL私钥文件路径
     ssl_session_timeout 5m;
     ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
     ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
     ssl_prefer_server_ciphers on;

    location / {
         root   /usr/share/nginx/html;
         index  index.html index.htm;
     }
    location /web1 {
   alias /usr/share/nginx/html/web1 ;
   index index.html;
 }
 location /web2 {
   alias /usr/share/nginx/html/web2 ;
   index index.html;
 }
 location /java1/ {

        proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header Host $http_host;

        proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection "upgrade";
         proxy_read_timeout 3600s;

        proxy_pass http://xxx.xxx.com:port1;
 }
 location /java2/ {

        proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header Host $http_host;

        proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection "upgrade";
         proxy_read_timeout 3600s;

        proxy_pass http://xxx.xxx.com:port2;
 }
 location /java3/ {

        proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header Host $http_host;

        proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection "upgrade";
         proxy_read_timeout 3600s;

        proxy_pass http://xxx.xxx.com:port3;
 }

}
}

4、重启nginx
docker restart nginx
5、检测是否配置成功

在浏览器输入域名或https://xxx.xxx.com/，输入http://ip，使用项目访问，各种项目皆访问成功，即配置成功
