本节主要说说前端的部署需要注意的点，本身renren-fast这个项目就是通过nodejs来进行开发的，nodejs编译后生成html，css，img所以，咱们不用在容器直接用nginx就可以访问静态文件。源码：https://github.com/limingios/netFuture/blob/master/前端/
https://github.com/daxiongYang/renren-fast-vue

修改连接地址

应该修改成http://192.168.66.151:6201/renren-fast;

打包

• 修改镜像，国内打包比较快点

  http://npm.taobao.org/

• 安装

  你可以使用我们定制的 cnpm (gzip 压缩支持) 命令行工具代替默认的 npm:

$ npm install -g cnpm --registry=https://registry.npm.taobao.org

这个目录上传到nginx上。

renren-nginx<1>

这里的nginx并不是做负载均衡的，而是做静态的html的静态运行环境的。

• 创建容器

  用宿主机的网段

  docker run -it -d --name fn1 \
  -v /root/fn1/nginx.conf:/etc/nginx/nginxc.conf \
  -v /root/fn1/renren-vue:/home/fn1/renren-vue \
  --privileged --net=host nginx

• 编写nginx的配置文件

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;
#tcp_nopush     on;

keepalive_timeout  65;

#gzip  on;

    location  /  {
        root  /home/fn1/renren-vue;
        index  index.html;
    }
}

#### 前端项目的双机热备负载均衡方案

> 之前已经设置了ff1 和ff2，都可以正常的访问后端，但是没有设置keepalived，他们之前无法争抢ip，无法做到双机热备。这次说说双机热备。

> 进入容器ff1然后安装keepalived

> keepalived必须在ff1所在的容器之内，也可以在docker仓库里面下载一个nginx-keepalived的镜像。这里直接在容器内安装keepalived。

1.  VI_1 名称可以自定义
2.  state MASTER | keepalived的身份（MASTER主服务器，BACKUP备份服务器，不会抢占虚拟机ip）。如果都是主MASTER的话，就会进行互相争抢IP，如果抢到了就是MASTER，另一个就是SLAVE。
3.  interface网卡，定义一个虚拟IP定义到那个网卡上边。网卡设备的名称。eth43是宿主机是网卡。
4.  virtual_router_id 51 | 虚拟路由标识，MASTER和BACKUP的虚拟路由标识必须一致。标识可以是0-255。
5.  priority 100 | 权重。MASTER权重要高于BACKUP 数字越大优选级越高。可以根据硬件的配置来完成，权重最大的获取抢到的级别越高。
6.  advert_int 1 | 心跳检测。MASTER与BACKUP节点间同步检查的时间间隔，单位为秒。主备之间必须一致。
7.  authentication | 主从服务器验证方式。主备必须使用相同的密码才能正常通信。进行心跳检测需要登录到某个主机上边所有有账号密码。
8.  virtual_ipaddress | 虚拟ip地址，可以设置多个虚拟ip地址，每行一个。根据上边配置的eth43上配置的ip。192.168.66.151 是自己定义的虚拟ip

PS：前后端部署基本是一样的都是按照思路，先启动多个容器，然后建立2个负载，负载内安装keepalived做热备。重点是想好端口。但是说实话，这是平常练习和个人项目，如果是多台机器，就不能这么搞了，下次一起通过docker swarm的网络方式让多台机器。
