**Load Balance** 📝 4 | 5 | 這篇文章主要接續上一篇 6 | 7 | [Docker + Django + Nginx + uWSGI + Postgres 基本教學 - 從無到有 ( Docker + Django + Nginx + uWSGI + Postgres Tutorial )](https://github.com/twtrubiks/docker-django-nginx-uswgi-postgres-tutorial) 8 | 9 | 繼續介紹，這次的重點會放在 Nginx 的 **Load Balance** 上 :blush: 10 | 11 | * [Youtube Tutorial PART 1 - 正向代理器 VS 反向代理器 -

Load Balance 之前，我會先帶大家了解一些名詞。 19 | 20 | 還記得在 [上一篇](https://github.com/twtrubiks/docker-django-nginx-uswgi-postgres-tutorial) 教學中，提到 Nginx 可以設定 反向代理器 嗎？ 21 | 22 | 那時候沒有詳細解釋什麼是 反向代理器 ，這邊我將先帶大家了解 23 | 24 | **正向代理器** 以及 **反向代理器** 的差別 :notebook: 25 | 26 | ### 正向代理器 VS 反向代理器 27 | 28 | #### 正向代理器 29 | 30 | 正向代理器是一個位於使用者端以及目標 Server 之間的 **代理伺服器 ( Proxy Server )**， 31 | 32 | 透過代理伺服器收發 Request / Respond 資料， 33 | 34 | ![](https://i.imgur.com/zWIk8QW.png) 35 | 36 | 如上圖，X 無法直接和 Z 請求資料，但是 Y 可以和 Z 請求資料 ( 於是 X 透過 Y 向 Z 請求資料 )， 37 | 38 | Y 得到資料後，再將資料回傳給 X，這樣 X 就能順利得到 Z 的資料了 。 39 | 40 | 通常正向代理器必須額外做一些設定才可以使用。 41 | 42 | 正向代理器，Client 和 Proxy 可視為同一個 LAN ，對 Server 是隱藏的。 43 | 44 | ![](https://i.imgur.com/MJ0Pr2q.png) 45 | 46 | 溫馨小提醒 :heart: 47 | 48 | * LAN ( Local Area Network )，又稱 區域網路 49 | 50 | * WAN ( Wide Area Network )，又稱 廣域網路 51 | 52 | * WLAN ( Wireless LAN )，又稱 無線區域網路 53 | 54 | 正向代理器是代理使用者端（ Client 端 ），替使用者端（ Client 端 ）收發 Request / Respond， 55 | 56 | 讓真正的使用者對伺服器端（ Server 端 ）隱藏。 57 | 58 | 可能你自己也有使用過（ 或正在使用 :grin: ）正向代理器 ，只是你不知道而以，像最常見的就是 **翻牆 ( VPN )** :smirk: 59 | 60 | 今天主角是阿鬼，阿鬼無法瀏覽 FB，但可以瀏覽 Server A，而阿鬼發現 Server A 可以訪問 FB， 61 | 62 | 於是阿鬼就透過 Server A 去瀏覽 FB，整個流程是，阿鬼透過 Server A 去瀏覽 FB，Server A 收到 63 | 64 | 來自阿鬼的 Request 時，去瀏覽 FB，FB 再把 Response 回傳給 Server A，Server A 再把收到的 65 | 66 | Response 回傳給阿鬼，這樣阿鬼就能順利得到 FB 的資料，這就是透過 Proxy ( 正向代理器 )。 67 | 68 | #### 反向代理器 69 | 70 | 反向代理器則相反過來，對於使用者端來說，反向代理器就好像是目標 Server， 71 | 72 | 使用者端也不需要做額外的設定， 73 | 74 | ![](https://i.imgur.com/kUBGgKz.png) 75 | 76 | 如上圖，雖然整個流程還是 X->Y->Z，但因為不用特別設定，所以使用者端會感覺好像直接是 X->Z， 77 | 78 | 反向代理器，Proxy 和 Server 屬於一個 LAN，對 Client 隱藏 79 | 80 | ![](https://i.imgur.com/j6wnvnt.png) 81 | 82 | 反向代理器是代理伺服器端（ Server 端 ），替伺服器端（ Server 端 ）收發 Request / Respond， 83 | 84 | 讓真正的伺服器（ Server 端 ）對使用者隱藏。 85 | 86 | 本次的主角 **Load Balance** 就是反向代理器的一種應用 :open_mouth: 87 | 88 | ## 教學 89 | 90 | 解釋了那麼多，我們要開始實戰 Nginx 的 Load Balance，範例一樣是使用 [上一篇](https://github.com/twtrubiks/docker-django-nginx-uswgi-postgres-tutorial) 做修改， 91 | 92 | 因為要做 Load Balance，所以增加一台主機（ service ），名稱命名為 [api2](https://github.com/twtrubiks/docker-django-nginx-uwsgi-postgres-load-balance-tutorial/tree/master/api2)，基本上內容 93 | 94 | 都和 [api](https://github.com/twtrubiks/docker-django-nginx-uwsgi-postgres-load-balance-tutorial/tree/master/api) 差不多，只是修改了一些名稱（ 方便區別而已 ），可參考 [docker-compose.yml](https://github.com/twtrubiks/docker-django-nginx-uwsgi-postgres-load-balance-tutorial/blob/master/docker-compose.yml)。 95 | 96 | 整體的 Load Balance 的概念可以參考下圖 97 | 98 | ![](https://i.imgur.com/RxUtPiz.png) 99 | 100 | 這樣有什麼好處呢 ？ 101 | 102 | 最直接的好處就是，如果一台掛了，整個系統還是不會死， 103 | 104 | 因為其他的 Server 還是正常工作:relaxed: 105 | 106 | 再來就是我們的主角 [my_nginx.conf](https://github.com/twtrubiks/docker-django-nginx-uwsgi-postgres-load-balance-tutorial/blob/master/nginx/my_nginx.conf)，其實主要也是修改這邊的設定而已 :laughing: 107 | 108 | ```config 109 | # the upstream component nginx needs to connect to 110 | upstream uwsgi { 111 | # server api:8001; # use TCP 112 | server unix:/docker_api/app.sock weight=4 ; # for a file socket 113 | server unix:/docker_api2/app2.sock weight=6; # for a file socket 114 | } 115 | 116 | # configuration of the server 117 | server { 118 | # the port your site will be served on 119 | listen 80; 120 | # index index.html; 121 | # the domain name it will serve for 122 | # substitute your machine's IP address or FQDN 123 | server_name twtrubiks.com www.twtrubiks.com; 124 | charset utf-8; 125 | 126 | client_max_body_size 75M; # adjust to taste 127 | 128 | # Django media 129 | # location /media { 130 | # alias /docker_api/static/media; # your Django project's media files - amend as required 131 | # } 132 | 133 | location /static { 134 | alias /docker_api/static; # your Django project's static files - amend as required 135 | } 136 | 137 | location / { 138 | uwsgi_pass uwsgi; 139 | include /etc/nginx/uwsgi_params; # the uwsgi_params file you installed 140 | } 141 | 142 | } 143 | ``` 144 | 145 | 其實設定並不難，只是在 `upstream` 裡面增加一台 Server 而已，後面的 `weight` 則代表權重， 146 | 147 | Nginx 預設會使用 round-robin 演算法來實作 Load balance。 148 | 149 | ### Load balancing methods 150 | 151 | Nginx 主要的 Load balance 有三種 152 | 153 | ****round-robin — requests to the application servers are distributed in a round-robin fashion**** 154 | 155 | 使用輪詢的方式，也可以加上 `weight` 權重，讓比較強的 Server 承受比較大的壓力（ `weight` 設定高一點）。 156 | 157 | ****least-connected — next request is assigned to the server with the least number of active connections**** 158 | 159 | 此種方式，Nginx 會將請求給負載 Loading 較輕的 Server，避免負載（A Server） Loading 已經很大了， 160 | 161 | 還將請求交給 A Server 處理。 162 | 163 | ****ip-hash — a hash-function is used to determine what server should be selected for the next request (based on the client's IP address)**** 164 | 165 | 不管是 round-robin 還是 least-connected 的 Load balance ，每個 User 送出的請求都可能會被分到不同的 166 | 167 | Server，並不能保證同一個 User 每次的請求都一定會連到同一台 Server， 168 | 因為這個原因，於是有了 ip-hash， 169 | 170 | 透過這個方法，會使用 ip 的方式將同一個 User 的請求都導到同一台 171 | Server （除非這台 Server 掛了 :sob: ） 172 | 173 | 介紹完了 Nginx 主要的三種 Load balance 演算法，至於要使用哪一種，就看你自己的需求了 :grinning: 174 | 175 | 更多範例以及詳細的說明可參考官網 176 | 177 | ( 建議閱讀 ，雖然我有幫大家整理重點出來了 :grinning: ) 178 | 179 | [http://nginx.org/en/docs/http/load_balancing.html](http://nginx.org/en/docs/http/load_balancing.html) 180 | 181 | ## 執行步驟 182 | 183 | 直接執行 `docker-compose up` 見證奇蹟 184 | 185 | 細部的圖就不再貼一次了，請參考 [上一篇](https://github.com/twtrubiks/docker-django-nginx-uswgi-postgres-tutorial) 186 | 187 | 會發現我們多了一台 `api2` 188 | 189 | ![](https://i.imgur.com/KhROEky.png) 190 | 191 | 接著開啟另一個 terminal，進入 `api` ( Django + uWSGI ) 的容器， 192 | 193 | 指令可參考之前的 [docker-tutorial-指令介紹](https://github.com/twtrubiks/docker-tutorial#指令介紹)， 194 | 195 | ```cmd 196 | docker exec -it bash 197 | ``` 198 | 199 | 執行 migrate 200 | 201 | ```cmd 202 | python manage.py makemigrations musics 203 | python manage.py migrate 204 | ``` 205 | 206 | ![](https://i.imgur.com/nQDwP7e.png) 207 | 208 | 建立 user 209 | 210 | ```cmd 211 | python manage.py createsuperuser 212 | ``` 213 | 214 | ![](https://i.imgur.com/saaDD7R.png) 215 | 216 | 最後再執行 217 | 218 | ```cmd 219 | python manage.py collectstatic 220 | ``` 221 | 222 | ![](https://i.imgur.com/1EKNNOx.png) 223 | 224 | 將 Django 中的 static files 收集起來，變成 static folder， 225 | 226 | 我們不需要再進入 `api2` 的 container 執行剛剛的動作，因為我們都是連同一個 db， 227 | 228 | 到這裡基本上就是完工了:smile: 229 | 230 | 瀏覽 [http://localhost:8080/api/music/](http://localhost:8080/api/music/) 確認是否正常。 231 | 232 | ## 執行畫面 233 | 234 | 瀏覽 [http://localhost:8080/api/music/](http://localhost:8080/api/music/) 235 | 236 | ![](https://i.imgur.com/jl43jST.png) 237 | 238 | ![](https://i.imgur.com/Fw6LjbE.png) 239 | 240 | 那要怎麼確定真的有 Load balance 呢？ 241 | 242 | 可以在頁面上瘋狂點擊 F5，然後我們觀察 terminal，你會發現 243 | 244 | ![](https://i.imgur.com/7xuFXw5.png) 245 | 246 | 有時候是 `api`，有時候是 `api2`，還記得前面設定的 `weight` 權重， 247 | 248 | `api` 和 `api2` 是 4:6，4:6 是什麼意思呢:question::question: 249 | 250 | 假如現在有 10 個 Request 進來，4 個 Request 會交給 `api` 這個 Server 處理， 251 | 252 | 而剩下的 6 個 Request 則會交給 `api2` 這個 Server 處理 :+1: 253 | 254 | `weight` 權重可以依照自己的需求設定。 255 | 256 | 接著再來模擬一台 Server 掛了的時候，如下圖，Server 因為某種原因掛了， 257 | 258 | ![](https://i.imgur.com/fRa1Q9t.png) 259 | 260 | 先透過 stop 指令將 `api` container 停止 261 | 262 | ( 模擬 `api` 這台 Server 掛了 ) 263 | 264 | ```cmd 265 | docker stop [OPTIONS] CONTAINER [CONTAINER...] 266 | ``` 267 | 268 | ![](https://i.imgur.com/LkoQeDc.png) 269 | 270 | ![](https://i.imgur.com/lHmMPUu.png) 271 | 272 | 然後再繼續瀏覽 [http://localhost:8080/api/music/](http://localhost:8080/api/music/)，你會發現網站正常 work ( 確實沒有掛掉 )， 273 | 274 | 而且 terminal 現在都只會輸出 `api2`， 275 | 276 | ![](https://i.imgur.com/RTdzQqX.png) 277 | 278 | 因為我們已經將 `api` 停止了（模擬機器意外掛了）， 279 | 280 | 有沒有很酷 :satisfied: 這就是最簡單的 Load balance :flushed: 281 | 282 | 範例是總共有兩台 server ( `api` 以及 `api2` )， 你也可以自己多新增幾台來玩玩看。 283 | 284 | ## 其他的負載平衡 285 | 286 | 除了 Nginx 的 Load banlance 之外，假設你的系統更龐大且有規模， 287 | 288 | 可以考慮使用更專業的負載平衡，像是 [HAProxy](http://www.haproxy.org/) ( High Availability Proxy ) ， 289 | 290 | 如果要專注在 Load banlance 上，選擇 [HAProxy](http://www.haproxy.org/) 應該會比 Nginx 的 291 | 292 | Load banlance 還來的好。 293 | 294 | 如果對 HAProxy 有興趣，可參考 [Docker Swarm + HAProxy](https://github.com/twtrubiks/docker-swarm-tutorial#docker-swarm--haproxy) :sunglasses: 295 | 296 | ## 後記： 297 | 298 | 這次主要介紹了 Nginx 的 Load Banlance 給大家，建議大家可以動手玩玩看，整體會比較有感覺 :smiley: 299 | 300 | 這次嘗試參考網路上的圖自己簡單的畫一遍，希望對大家多多少少有幫助:flushed: 301 | 302 | 如果有在玩像是 AWS 的人，可以知道還有一種東西更狂，就是 異地同步備份，大家有興趣自行研究:sunglasses: 303 | 304 | 如果有任何講錯的地方，請麻煩大家和我說，我會再修改，感謝各位的閱讀:v: 305 | 306 | 下一步可以試試看用 Docker scale 的方法來完成( 更好的寫法 )，可參考 [better](https://github.com/twtrubiks/docker-django-nginx-uwsgi-postgres-load-balance-tutorial/tree/better)
