openresty+health_check+consul安装

项目中经常要搭建nginx环境，记录下安装脚本，备忘；

1. 安装依赖:

   yum install readline-devel pcre-devel openssl-devel gcc
   

2. 下载依赖包：

   git clone https://github.com/xiaokai-wang/nginx_upstream_check_module.git
   wget --secure-protocol=TLSv1 --no-check-certificate https://openresty.org/download/openresty-1.11.2.5.tar.gz
   git clone https://github.com/weibocom/nginx-upsync-module.git
   git clone https://github.com/sumory/orange.git
   git clone https://github.com/sumory/lor.git
   

3. 准备nginx_upstream_check_module模块，需要先对nginx打patch:

   tar -xvf openresty-1.11.2.5.tar.gz -C /data/exec/
   cd /data/exec/openresty-1.11.2.5/bundle/nginx-1.11.2
   

patch -p0 < /data/exec/nginx_upstream_check_module/check_1.11.1+.patch
```

4. 修改nginx-upsync-module模块ngx_http_upsync_module.c的1688行：

   node = cJSON_GetObjectItem(server_next, "Node")
   

改为:

```
node = cJSON_GetObjectItem(server_next, "Service")
```

5. 安装openresty:

   ./configure --prefix=/data/exec/openresty --with-http_stub_status_module --add-module=/data/exec/nginx_upstream_check_module --add-module=/data/exec/nginx-upsync-module
   

make & make install

```

6. 安装Lor,默认安装到/usr/local目录：

cd lor
make install

7. 安装orange

cd orange
make install

8. 修改orange的配置文件，增加upstream:

   upstream xiu-relation-server {
           upsync 10.221.83.98:8500/v1/health/service/xiu-relation-server upsync_timeout=6m upsync_interval=500ms upsync_type=consul_health strong_dependency=on;
           upsync_dump_path /usr/local/openresty/nginx/conf/servers/servers_xiu_relation_server.conf;
           include /usr/local/openresty/nginx/conf/servers/servers_xiu_relation_server.conf;
   
           check interval=1000 rise=2 fall=2 timeout=3000 type=tcp default_down=false;
           #check_http_send "HEAD / HTTP/1.0\r\n\r\n";
           #check_http_expect_alive http_2xx http_3xx;
   
       }
   

location = /upstream_show {
            upstream_show;
        }

        location = /upstream_status {
            check_status;
            access_log off;
        }

9. 修改oragne的配置文件orange.conf,主要配置mysql的地址；

10. 建立nginx的软链接：

ln -s /data/exec/openresty/nginx/sbin/nginx /usr/local/bin/nginx

11. 通过orange start/stop/restart管理应用,假设服务器ip为10.1.1.2，upstream相关指令放在80端口

• 管理界面：http://10.1.1.2:9999/
• 查看upstream配置：http://10.1.1.2/upstream_status
• 查看upstream状态:http://10.1.1.2/upstream_show
