项目中经常要搭建nginx环境，记录下安装脚本，备忘；

安装依赖:

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

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

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
```

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")
```

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

```

安装Lor,默认安装到/usr/local目录：

cd lor
make install

安装orange

cd orange
make install

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;
        }

修改oragne的配置文件orange.conf,主要配置mysql的地址；
建立nginx的软链接：

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

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
