Задача – поднять реверс-прокси на NGINX, который будет проксировать данные к WebApp в Azure.
NGINX будет работать на виртуальной машине.

Создание VM
Используем Azure CLI для создания машины.
Логинимся:
$ azure login
Проверяем режим Azure CLI – нужен arm (Resource Manager mode):
$ azure config list | grep arm data: mode arm
Если сейчас CLI находится в режиме Service Management mode – переключиться можно с помощью:
$ azure config mode arm info: Executing command config mode info: New mode is arm info: config mode command OK
Переключаемся на нужную подписку:
$ azure account list info: Executing command account list data: Name Id Current State data: ------------- ------------------------------------ ------- -------- data: Free Trial 97214f99-***-***-***-715556cd5906 true Enabled data: Pay-As-You-Go fe37db50-***-***-***-66145cdbd735 false Disabled data: Pay-As-You-Go 0a4f2b9c-***-***-***-40b17ef8c3ab false Enabled

$ azure vm list info: Executing command vm list + Getting virtual machines data: ResourceGroupName Name ProvisioningState PowerState Location Size data: ----------------- ---- ----------------- ---------- ---------- ----------- data: D2 gw Succeeded VM running westeurope Standard_D1 info: vm list command OK
Находим IP, который потребуется при создании субдомена:
$ azure vm show -g D2 -n gw | grep IP data: Public IP address :13.80.9.248
Пробуем подключиться:
$ ssh [email protected] The authenticity of host '13.80.9.248 (13.80.9.248)' can't be established. ECDSA key fingerprint is 20:a7:0b:33:61:11:ec:98:3a:83:77:2b:e3:0f:7e:83.

[email protected]'s password: Welcome to Ubuntu 14.04.4 LTS (GNU/Linux 3.19.0-58-generic x86_64) ... setevoy@gw:~$
Там же находим Network interface – его Name понадобится при создании Security group:

Далее треубется открыть порт 80 для входящих соединений, т.к. по умолчанию доступ открыт только на порт 22:
$ telnet 13.80.9.248 80 Trying 13.80.9.248... telnet: Unable to connect to remote host: Connection timed out
Проверяем текущие Security группы:
$ azure network nsg list info: Executing command network nsg list + Getting the network security groups warn: No network security groups found
Создаем новую группу с именем gw_in:
$ azure network nsg create -g D2 -n gw_in -l westeurope info: Executing command network nsg create + Looking up the network security group "gw_in" + Creating a network security group "gw_in" data: Id : /subscriptions/97214f99-***-***-***-715556cd5906/resourceGroups/D2/providers/Microsoft.Network/networkSecurityGroups/gw_in data: Name : gw_in data: Type : Microsoft.Network/networkSecurityGroups data: Location : westeurope data: Provisioning state : Succeeded data: Security rules: data: Name Source IP Source Port Destination IP Destination Port Protocol Direction Access Priority data: ----------------------------- ----------------- ----------- -------------- ---------------- -------- --------- ------ -------- data: AllowVnetInBound VirtualNetwork * VirtualNetwork * * Inbound Allow 65000 data: AllowAzureLoadBalancerInBound AzureLoadBalancer * * * * Inbound Allow 65001 data: DenyAllInBound * * * * * Inbound Deny 65500 data: AllowVnetOutBound VirtualNetwork * VirtualNetwork * * Outbound Allow 65000 data: AllowInternetOutBound * * Internet * * Outbound Allow 65001 data: DenyAllOutBound * * * * * Outbound Deny 65500
Добавляем к ней правило для входящих соединений на порт 80 с именем 80inallow:
$ azure network nsg rule create -g D2 -a gw_in -n 80inallow -p tcp -o '*' -u 80 -c Allow info: Executing command network nsg rule create warn: Using default source port: 80 warn: Using default source address prefix: * warn: Using default destination address prefix: * warn: Using default priority: 100 warn: Using default direction: Inbound + Looking up the network security group "gw_in" + Looking up the network security rule "80inallow" + Creating a network security rule "80inallow" data: Id : /subscriptions/97214f99-***-***-***-715556cd5906/resourceGroups/D2/providers/Microsoft.Network/networkSecurityGroups/gw_in/securityRules/80inallow data: Name : 80inallow data: Type : Microsoft.Network/networkSecurityGroups/securityRules data: Provisioning state : Succeeded data: Source IP : * data: Source Port : 80 data: Destination IP : * data: Destination Port : 80 data: Protocol : Tcp data: Direction : Inbound data: Access : Allow data: Priority : 100 info: network nsg rule create command OK
Аналогично – для порта 22, SSH, но с более высоким приоритетом, что бы избежать ошибки вида:
error: Security rule 80inallow conflicts with rule sshallow. Rules cannot have the same Priority and Direction.
$ azure network nsg rule create -g D2 -a gw_in -n sshallow -p tcp -o '*' -u 22 -c Allow -y 101
Подключаем интерфейс к этой группе безопасности:
$ azure network nic set -g D2 -n gw-weste-387985789-nic --network-security-group-name gw_in info: Executing command network nic set + Looking up the network interface "gw-weste-387985789-nic" + Looking up the network security group "gw_in" + Updating network interface "gw-weste-387985789-nic" data: Id : /subscriptions/97214f99-***-***-***-715556cd5906/resourceGroups/D2/providers/Microsoft.Network/networkInterfaces/gw-weste-387985789-nic data: Name : gw-weste-387985789-nic data: Type : Microsoft.Network/networkInterfaces data: Location : westeurope data: Provisioning state : Succeeded data: MAC address : 00-0D-3A-23-20-8B data: Enable IP forwarding : false data: Network security group : /subscriptions/97214f99-***-***-***-715556cd5906/resourceGroups/D2/providers/Microsoft.Network/networkSecurityGroups/gw_in data: Virtual machine : /subscriptions/97214f99-***-***-***-715556cd5906/resourceGroups/D2/providers/Microsoft.Compute/virtualMachines/gw data: IP configurations: data: Name : ipconfig1462018264060 data: Provisioning state : Succeeded data: Public IP address : /subscriptions/97214f99-***-***-***-715556cd5906/resourceGroups/D2/providers/Microsoft.Network/publicIPAddresses/gw-weste-387985789-pip data: Private IP address : 10.0.1.4 data: Private IP allocation method : Dynamic data: Subnet : /subscriptions/97214f99-***-***-***-715556cd5906/resourceGroups/D2/providers/Microsoft.Network/virtualNetworks/gw-weste-387985789-vnet/subnets/gw-weste-387985789-snet
Проверяем:
$ telnet 13.80.9.248 80 Trying 13.80.9.248... Connected to 13.80.9.248. Escape character is '^]'.
Создание WebApp
В WebApp у нас будет работать приложение, к которому мы будем проксировать данные через созданную VM.
Проверяем имеющиеся приложения:
$ azure webapp list -g D2 info: Executing command webapp list + Listing webapps info: No web apps found.
Создаем WebApp:
$ azure webapp create -g D2 -n backappforgw -l westeurope -p WEgwapp info: Executing command webapp create + Creating webapp backappforgw info: Webapp backappforgw has been created
Проверяем:
$ azure webapp show -g D2 -n backappforgw info: Executing command webapp show + Getting webapp data: Web app Name : backappforgw data: SKU : Standard data: Enabled : true data: Last Modified : 2016-04-30T13:52:36.29 data: Location : West Europe data: data: Host Name data: ------------------------------ data: backappforgw.azurewebsites.net
$ curl -sr 0-1024 http://backappforgw.azurewebsites.net <!DOCTYPE html><html><head> <title>Microsoft Azure Web App - Welcome</title> ...
Настройка DNS
Далее будут использоваться два субдомена:
- gw.setevoy.org.ua: шлюз с NGINX;
- app.setevoy.org.ua: созданное приложение, к которому будет проксироваться трафик, но с
IN Aсозданной VM;
Что бы подключить внешний домен к приложению в Azure – необходимо создать запись авторизации вида:
awverify.app.setevoy.kiev.ua CNAME awverify.backappforgw.azurewebsites.net
При создания app.setevoy.org.ua – указываем IP шлюза, в результате получается примерно такая картина:
Подключаем новый субдомен в Portal > App Services > backappforgw > Settings > Custom domains and SSL > Bring External Domains:
И оттуда же записываем IP – 104.47.151.115, который далее используем при настройке NGINX.
Настройка NGINX
На созданной VM устанавливаем NGINX:
$ sudo -s # apt-get update # apt-get install nginx
Создаем файл конфигурации /etc/nginx/sites-available/app.setevoy.kiev.ua.conf:
server {
server_name app.setevoy.kiev.ua;
access_log /var/log/nginx/app.setevoy.kiev.ua-access.log;
error_log /var/log/nginx/app.setevoy.kiev.ua-error.log;
root /usr/share/nginx/html;
location / {
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://104.47.151.115;
}
}
Создаём симлинк в каталог sites-enabled (Debian/Ubuntu):
# ln -s /etc/nginx/sites-available/app.setevoy.kiev.ua.conf /etc/nginx/sites-enabled/
Проверяем:
# ls -l /etc/nginx/sites-enabled/ total 0 lrwxrwxrwx 1 root root 51 Apr 30 14:23 app.setevoy.kiev.ua.conf -> /etc/nginx/sites-available/app.setevoy.kiev.ua.conf lrwxrwxrwx 1 root root 34 Apr 30 13:06 default -> /etc/nginx/sites-available/default
# nginx -t nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful
Перегружаем конфиги:
# service nginx reload * Reloading nginx configuration nginx
И пробуем зайти:
Готово.
