2. 简单Demo 2.1 安装并配置Consul

# 解压包
unzip consul_1.0.6_linux_amd64.zip
# 移动consul到格式位置
mv consul/root/services/account_consul/
# 启动consul
/root/services/account_consul/consul agent-server-bootstrap-expect=1-data-dir=/root/data/consul/-node=accounting01-bind=172.31.132.207-config-dir=/root/data/consul_config/-client0.0.0.0-ui
# 添加upstreams配置
curl-XPUT http://172.31.132.207:8500/v1/kv/upstreams/accounting/127.0.0.1:8000
curl-XPUT http://172.31.132.207:8500/v1/kv/upstreams/accounting/127.0.0.1:8001
访问:8500/ui/
上图我们可以看出,我们已经通过http请求存储了upstreams配置信息, 接下来我们需要让Nginx从consul自动更新upstreams配置;
2.2 重新编译安装Nginx,添加upsync模块 2.2.1 install

# 解压
tar-zxvf nginx-1.8.0.tar.gz
unzip nginx-upsync-1.8.x.zip
# 编译安装
cd nginx-1.8.0
./configure –prefix=/usr/local/nginx –with-pcre –with-http_stub_status_module –with-http_ssl_module –with-http_gzip_static_module –with-http_realip_module –with-http_sub_module –add-module=/root/packages/nginx-upsync-module-nginx-upsync-1.8.x
make&&make install
# 检查Nginx是否按照成功
/usr/local/nginx/sbin/nginx
2.2.2 config

vim/usr/local/nginx/conf/nginx.conf
# 修改用户
(PS:由于我是root环境启动的服务,若Nginx的用户不是root的话,某些文件无法访问,例如:静态文件)
user root;
# 添加额外配置文件路径
(PS:非必须,但是我习惯这么做)
