jetlinks以及所需中间件的集群部署

注意：

仅专业版以上支持。
本文档以172.16.4.13、172.16.4.12、172.16.4.11三台服务器来搭建集群。

redis集群安装配置

这里准备在一台服务器上搭建一个三主三从的redis集群。

  1. 安装redis 先下载redis集群部署 - 图2 (opens new window),本文档以redis5.0.5为例。
    下载完成后进行解压、编译、安装。

注意：

redis是由C语言编写的，它的运行需要C环境，所以编译前需安装 gcc。

  1. 新建一个cluster文件夹，用来存放集群节点目录。
    分别在172.16.4.11上创建7000、7003、7001、7004、7002、7005六文件夹，，这些节点分别使用7000、7003、7001、7004、7002、7005端口，以7000节点为例配置如下：
  1. port 7000
  2. bind 172.16.4.11
  3. cluster-enabled yes
  4. cluster-config-file nodes_7000.conf
  5. cluster-node-timeout 5000
  6. appendonly no
  7. daemonize  yes

其他节点只需修改端口和文件名，依次按此进行配置即可，配置完成后启动节点。

注意：

建议appendonly在从节点开启，主节点关闭。

  1. 主从节点分配
  1. redis-cli --cluster create 172.16.4.11:7000 172.16.4.11:7001 172.16.4.11:7002 172.16.4.11:7003 172.16.4.11:7004 172.16.4.11:7005 --cluster -replicas 1

注意：

其中-replicas 1表示每个主节点1个从节点

  1. 查看集群节点信息
  1. ops@jetlinks-server-3:~/data/redis-5.0.5$ redis-cli -h 172.16.4.11  -p 7000 cluster nodes
  2. 562558e5afa0575d1059c47b9531a37cd75a9190 172.16.4.11:7003@17003 slave 9174a3ebcdbda174ec9189fbae0e38d9bbeeff5f 0 1594368796612 4 connected

redis集群搭建请参考redis官方文档集群部署 - 图3 (opens new window)

elasticsearch集群安装配置

  1. 分别在三台服务器上安装elasticsearch 前往官网下载集群部署 - 图4 (opens new window)。
    下载完成后安装es。
  2. 配置elasticsearch.yml文件
  1. ops@jetlinks-server-3:~/elasticsearch/config$ sudo vi elasticsearch.yml 
  2. # ======================== Elasticsearch Configuration =========================
  3. #
  4. # NOTE: Elasticsearch comes with reasonable defaults for most settings.
  5. #       Before you set out to tweak and tune the configuration, make sure you
  6. #       understand what are you trying to accomplish and the consequences.
  7. #
  8. # The primary way of configuring a node is via this file. This template lists
  9. # the most important settings you may want to configure for a production cluster.
  10. #
  11. # Please consult the documentation for further information on configuration options:
  12. # https://www.elastic.co/guide/en/elasticsearch/reference/index.html
  13. #
  14. # ---------------------------------- Cluster -----------------------------------
  15. #
  16. # Use a descriptive name for your cluster:
  17. #
  18. cluster.name: es-cluster
  19. #
  20. # ------------------------------------ Node ------------------------------------
  21. #
  22. # Use a descriptive name for the node:
  23. #
  24. node.name: node-3
  25. #
  26. # Add custom attributes to the node:
  27. #
  28. #node.attr.rack: r1
  29. #
  30. # ----------------------------------- Paths ------------------------------------
  31. #
  32. # Path to directory where to store the data (separate multiple locations by comma):
  33. #
  34. #path.data: /path/to/data
  35. #
  36. # Path to log files:
  37. #
  38. #path.logs: /path/to/logs
  39. #
  40. # ----------------------------------- Memory -----------------------------------
  41. #
  42. # Lock the memory on startup:
  43. #
  44. #bootstrap.memory_lock: true
  45. #
  46. # Make sure that the heap size is set to about half the memory available
  47. # on the system and that the owner of the process is allowed to use this
  48. # limit.
  49. #
  50. # Elasticsearch performs poorly when the system is swapping the memory.
  51. #
  52. # ---------------------------------- Network -----------------------------------
  53. #
  54. # Set the bind address to a specific IP (IPv4 or IPv6):
  55. #
  56. network.host: 172.16.4.11
  58. transport.tcp.port: 9300
  59. #
  60. # Set a custom port for HTTP:
  61. #
  62. http.port: 9200
  63. #
  64. # For more information, consult the network module documentation.
  65. #
  66. # --------------------------------- Discovery ----------------------------------
  67. #
  68. # Pass an initial list of hosts to perform discovery when new node is started:
  69. # The default list of hosts is ["127.0.0.1", "[::1]"]
  70. #
  71. discovery.zen.ping.unicast.hosts: ["172.16.4.13:9300", "172.16.4.12:19300","172.16.4.11:9300"]
  72. #
  73. # Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
  74. #
  75. discovery.zen.minimum_master_nodes: 1
  76. #
  77. # For more information, consult the zen discovery module documentation.
  78. #
  79. # ---------------------------------- Gateway -----------------------------------
  80. #
  81. # Block initial recovery after a full cluster restart until N nodes are started:
  82. #
  83. #gateway.recover_after_nodes: 3
  84. #
  85. # For more information, consult the gateway module documentation.
  86. #
  87. # ---------------------------------- Various -----------------------------------
  88. #
  89. # Require explicit names when deleting indices:
  90. #
  91. #action.destructive_requires_name: true

三台服务器不同的配置：

  1. #172.16.4.11
  2. node.name: node-3  
  3. network.host:172.16.4.11
  1. #172.16.4.12
  2. node.name: node-2  
  3. network.host:172.16.4.12
  1. #172.16.4.13
  2. node.name: node-1  
  3. network.host:172.16.4.13

3 在三台服务器上分别启动es

  1. ./bin/elasticsearch

数据库启动

本文档案例使用docker启动postgresql，可参考docker-compose.yml集群部署 - 图5 (opens new window)文件中的postgresql配置。

注意：

在多台服务器上启动jetlinks，配置中的jetlinks.server-id必须互不相同。

在项目根目录执行：

  1. mvn clean package -DskipTests
  1. 分别在三台服务器上启动jetlinks 文档以脚本方式启动，脚本如下：
  1. #!/bin/bash
  2. nohup java -jar -Dspring.application.name=jetlinks-cluster-test-3   jetlinks-standalone.jar >jetlinks-pro.log 2>&1 &

注意：

三台服务启动的jetlinks.server-id应该互不相同，在application.yml中jetlinks.server-id引用了spring.application.name，所以此处的name应不相同。

nginx配置

通过nginx来代理前后端。

  1. 安装nginx
    前往官网下载集群部署 - 图6 (opens new window) 下载完成后解压、编译、安装。
  2. 修改配置文件

配置文件如下：

  1. upstream iotserver {
  2.   server 172.16.4.11:8844;
  3.   server 172.16.4.12:8844;
  4.   server 172.16.4.13:8844;
  5. }
  7. upstream webserver {
  8.   server 172.16.4.11:9000;
  9. }
  11. upstream fileserver {
  12.   server 172.16.4.11:8844; #此处指定文件上传到该服务器上
  13. }
  15. server {
  17.   listen       8080;
  18.   server_name  demo2.jetlinks.cn;
  20.   location ^~/upload/ {
  21.     proxy_pass http://fileserver;
  22.     proxy_set_header Host $host:$server_port;
  23.     proxy_set_header X-Real-IP  $remote_addr;
  24.     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  25.   }
  27.   location ^~/jetlinks/file/static {
  28.     proxy_pass http://fileserver/file/static;
  29.     proxy_set_header X-Forwarded-Proto $scheme;
  30.     proxy_set_header Host $host:$server_port;
  31.     proxy_set_header X-Real-IP  $remote_addr;
  32.     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  33.     proxy_send_timeout      30m;
  34.     proxy_read_timeout      30m;
  35.     client_max_body_size    100m;
  36.   }
  38.   location ^~/jetlinks/ {
  39.     proxy_pass http://iotserver/;
  40.     proxy_set_header X-Forwarded-Proto $scheme;
  41.     proxy_set_header Host $host:$server_port;
  42.     proxy_set_header X-Real-IP  $remote_addr;
  43.     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  44.     proxy_http_version 1.1;
  45.     proxy_set_header Upgrade $http_upgrade;
  46.     proxy_set_header Connection "upgrade";
  47.     proxy_connect_timeout   1;
  48.     proxy_buffering off;
  49.     chunked_transfer_encoding off;
  50.     proxy_cache off;
  51.     proxy_send_timeout      30m;
  52.     proxy_read_timeout      30m;
  53.     client_max_body_size    100m;
  54.   }
  56.   location / {
  57.     proxy_pass http://webserver/;
  58.   }
  59. }
  1. 启动
  1. systemctl status nginx.service

tcp负载均衡配置方式

用于代理设备连接。此处使用nginx作为演示,也可以使用LVS,haProxy等方式。

配置文件：

  1. load_module /usr/lib/nginx/modules/ngx_stream_module.so;
  2. user  root;
  3. worker_processes  1;
  5. error_log  /etc/nginx/log/error.log warn;
  6. pid        /var/run/nginx.pid;
  9. events {
  10.     worker_connections  1024;
  11. }
  13. stream {
  15.    upstream tcp-test {
  16.        hash $remote_addr consistent;
  17.        server 172.16.4.13:1889 max_fails=3 fail_timeout=10s;
  18.        #server 172.16.4.12:1889 max_fails=3 fail_timeout=10s;
  19.        server 172.16.4.11:1889 max_fails=3 fail_timeout=10s;
  20.    }
  22.    server {
  24.        listen 1884;
  26.        proxy_pass tcp-test;
  28.        proxy_connect_timeout 30s;
  30.        proxy_timeout 30s;
  31.    }
  32. }

注意：

此配置监听的MQTT的1884端口，代理到服务器上的1889。如需代理自定义端口需保持代理端口与jetlinks平台中网络组件开启的端口一致。 如此处平台中MQTT服务网络组件设置的端口应为1889。
