用<Centos7配置LNMP nginx10+mariadb+php5.6>安装nginx后,
是没有nginx-upsync-module的.如此一来可能还不如直接编译安装,
但是这样安装好处在于,可以方便使用systemtl来管理nginx,不需要自己去添加服务,懒人必备.
然后再找同样版本的nginx,编译安装一遍,加进自己的模块.

| wget http://nginx.org/download/nginx-1.12.1.tar.gz
tar -zxvf nginx-1.12.1.tar.gz
git clone https://github.com/onecer/nginx-upsync-module.git

添加模块 --add-module=../nginx-upsync-module 其它模块有需要的自己加

make && make install

注意路径,我这里安装好后,路径是/usr/local/nginx/
添加软连接到常用路径ln -s /usr/local/nginx/sbin/nginx /usr/sbin/nginx
添加服务文件:
vim /usr/lib/systemd/system/nginx.service
服务描述文件里面 /var/run/nginx.pid 一定要和 nginx.conf 地址对应上.不然启动获取不到pid.

发现行不通,服务我是部署在docker swarm里面的.我获取的服务数据是这样的.[ServiceAddress]里面注册的是内网IP

现在有几条路走.
Fork nginx-upsync-module 的源码 修改 ngx_http_upsync_consul_health_parse_json(void *data) 函数的处理,让它返回node的Address
摒弃全自动,手动添加节点信息到Consul KV
别用这种方式了,直接添加nginx节点.
nginx装集群内
我选了第二种方法.主要是第一种的话,固然方便点,但是最终还是走routing mesh,性能没有提升.第四种麻烦,第三种增加服务会中断服务才能更新.
最后还是用了第一种，对源码做了些小修改，上面源码已经是改过的，没改的源码地址，是注释掉的那个。
