10年积累的网站设计、成都做网站经验，可以快速应对客户对网站的新想法和需求。提供各种问题对应的解决方案。让选择我们的客户得到更好、更有力的网络服务。我虽然不认识你，你也不认识我。但先网站策划后付款的网站建设流程，更有郓城免费网站建设让你可以放心的选择与我们合作。

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/

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/

「实战篇」开源项目docker化运维部署-前端java部署（八）

  • 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

-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

#### 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。
