This section mainly talks about the deployment of the front-end need to pay attention to the point, itself renren-fast this project is developed through nodejs, nodejs compiled to generate html,css,img so, we do not have to use nginx directly in the container to access static files. Source code: https://github.com/limingios/netFuture/blob/master/ front end /

Https://github.com/daxiongYang/renren-fast-vue

Modify connection address

Should be modified to http://192.168.66.151:6201/renren-fast;

Pack and modify the image. Domestic packaging is faster.

Http://npm.taobao.org/

Installation

You can use our customized cnpm (gzip Compression support) command line tool instead of the default npm:

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

This directory is uploaded to nginx.

The nginx here is not to do load balancing, but to do static html static running environment.

# dual-server hot backup load balancer solution for frontend project > ff1 and ff2 have been set before, and the backend can be accessed normally, but without keepalived, they cannot compete for ip before and cannot achieve dual-server hot backup. This time, let's talk about the dual-computer hot standby. !

1. VI_1 name can be customized 2. State MASTER | identity of keepalived (MASTER master server, BACKUP backup server, will not preempt virtual machine ip). If they are all main MASTER, they will compete with each other for IP. If they get it, it will be MASTER, and the other is SLAVE. 3. Interface network card, define a virtual IP definition to that network card. The name of the network card device. Eth43 is the host and the network card. 4. Virtual_router_id 51 | Virtual routing identity. The virtual routing identifiers of MASTER and BACKUP must be the same. The identity can be 0-255. 5. Priority 100 | weight. The weight importance of MASTER is higher than that of BACKUP. The larger the number is, the higher the priority level is. It can be done according to the configuration of the hardware, and the higher the level of grabbing the largest weight. 6. Advert_int 1 | heartbeat detection. The time interval, in seconds, for synchronization checks between MASTER and BACKUP nodes. The master and backup must be consistent. 7. Authentication | Master / slave server verification method. Master and standby must use the same password in order to communicate properly. For heartbeat detection, you need to log in to a host with an account password. 8. Virtual_ipaddress | Virtual ip address. You can set multiple virtual ip addresses, one for each line. According to the ip configured on the eth43 configured above. 192.168.66.151 is a self-defined virtual ip* startup keeplived > in-container launch.
