将 cloud-nginx-file 结合开源项目 ngx_dynamic_upstram，实现对nginx灰度发布功能
cloud-nginx-file 地址(java编写)：
https://github.com/kanhai001/spring-cloud-learning/tree/master/cloud-nginx-file
ngx_dynamic_upstram地址(C编写)：
将ngx_dynamic_upstram作为nginx的一个module 添加到nginx
./configure --add-module=./ngx_dynamic_upstream-0.1.6
并make && make install,并执行，查看是否编译模块成功
/usr/local/nginx/sbin/nginx -V
修改nginx.conf 配置server运行访问的IP地址：
upstream backends {
zone zone_for_backends 1m;
server 127.0.0.1:6001 weight=1 max_fails=2 fail_timeout=30;
server 127.0.0.1:6002 weight=1 max_fails=2 fail_timeout=30;
server 127.0.0.1:6003 weight=1 max_fails=2 fail_timeout=30;
}
server {
listen 6000;
location /dynamic {
allow 127.0.0.1;
deny all;
dynamic_upstream;
}
location / {
proxy_pass http://backends;
}
}
将项目jar包发布至服务器，并启动，启动方式：
- 1）安装为系统服务
$ sudo ln -s /data/apps/cloud-nginx-file.jar /etc/init.d/cloud-nginx-file
启动项目并制定读取配置文件的地址
$ /etc/init.d/cloud-nginx-file start -Dspring.file.location=/data/apps/cloud-nginx-file/cnfig/
- 2）nohup 后台启动
$ nohup java -jar -Dserver.port=8080 -Dspring.file.location=/data/apps/cloud-nginx-file/config ./cloud-nginx-file.jar >nginx-file.log &
