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

#### 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。
