pm2運行json文件啓動node項目及pm2-web的安裝

定義運行配置文件

咱們能夠預約義一個配置文件，而後制定運行這個配置文件，好比咱們定義一個文件app.json，內容以下：node

[root@jenkins-master linux]# cat app.json   
{
"apps":[
    {
      "name": "service-sk_platform_professional_dev",
      "cwd": "/data/source/service-sk_platform_professional_dev/publish/",
      "script": "/data/source/service-sk_platform_professional_dev/publish/service/server.js",
      "log_date_format": "YYYY-MM-DD HH:mm Z",
      "error_file": "/data/pm2-log/errlogs/service-sk_platform_professional_dev-err.log",
      "out_file": "/data/pm2-log/outlogs/service-sk_platform_professional_dev-out.log",
      "pid_file": "/data/pm2-log/outlogs/service-sk_platform_professional_dev.pid",
      "instances": 1,
      "node_args": "--inspect=0.0.0.0:33111",
      "min_uptime": "20s",
      "max_restarts": 50,
      "watch": false,
      "merge_logs": true,
      "exec_interpreter": "node",
      "exec_mode": "fork",
    }
    ]
}

[root@node-44 ~]# cat app.json 
{
  "apps":[
    {
      "name": "sk_service_calculate_convert_dev",
      "cwd": "/data/source/sk_service_calculate_convert_dev/publish/",

      "watch": false,
      "merge_logs": true,
      "exec_interpreter": "node",
      "exec_mode": "fork",
},{
      "name": "sk_service_calculate_convert_dev2",
      "cwd": "/data/source/sk_service_calculate_convert_dev/publish/",
      "script": "/data/source/sk_service_calculate_convert_dev/publish/service/server.js",
      "args": "'debug' '12345'",
      "log_date_format": "YYYY-MM-DD HH:mm Z",
      "error_file": "/data/pm2-log/errlogs/sk_service_calculate_convert2_dev-err.log",
      "out_file": "/data/pm2-log/outlogs/sk_service_calculate_convert2_dev-out.log",
      "pid_file": "/data/pm2-log/outlogs/sk_service_calculate_convert2_dev.pid",
      "instances": 1,
      "min_uptime": "20s",
      "max_restarts": 50,
      "watch": false,
      "merge_logs": true,
      "exec_interpreter": "node",
      "exec_mode": "fork",
  },{
      "name": "sk_service_calculate_convert_dev3",
      "cwd": "/data/source/sk_service_calculate_convert_dev/publish/",
      "script": "/data/source/sk_service_calculate_convert_dev/publish/service/server.js",
      "args": "'debug' '12344'",
      "log_date_format": "YYYY-MM-DD HH:mm Z",
      "error_file": "/data/pm2-log/errlogs/sk_service_calculate_convert3_dev-err.log",
      "out_file": "/data/pm2-log/outlogs/sk_service_calculate_convert3_dev-out.log",
      "pid_file": "/data/pm2-log/outlogs/sk_service_calculate_convert3_dev.pid",
      "instances": 1,
      "min_uptime": "20s",
      "max_restarts": 50,
      "watch": false,
      "merge_logs": true,
      "exec_interpreter": "node",
      "exec_mode": "fork",
  },{
      "name": "sk_service_calculate_convert_dev4",
      "cwd": "/data/source/sk_service_calculate_convert_dev/publish/",
      "script": "/data/source/sk_service_calculate_convert_dev/publish/service/server.js",
      "args": "'debug' '12343'",
      "log_date_format": "YYYY-MM-DD HH:mm Z",
      "error_file": "/data/pm2-log/errlogs/sk_service_calculate_convert4_dev-err.log",
      "out_file": "/data/pm2-log/outlogs/sk_service_calculate_convert4_dev-out.log",
      "pid_file": "/data/pm2-log/outlogs/sk_service_calculate_convert4_dev.pid",
      "instances": 1,
      "min_uptime": "20s",
      "max_restarts": 50,
      "watch": false,
      "merge_logs": true,
      "exec_interpreter": "node",
      "exec_mode": "fork",
  }
]
}

for (int i = 0;i<"${node_number}".toInteger();i++){
                     Integer nodeport=10000+i
                        sh "cat /data/ansible/playbook/linux/linux_app.json |sed -e 's/sourcepath_node_Jenvironment/${projectname}_${environment}_${i}/g' -e 's/sourcepath_Jenvironment/${projectname}_${environment}/g' -e 's/process_mode/${process_mode}/g' -e 's/node_port/${nodeport}/g' >>${WORKSPACE}/publish/app.json"
                        sh(script: "echo -n ',\r\n' >>${WORKSPACE}/publish/app.json")
                    
                    }

而後能夠經過,運行這個App。

pm2 start app.jsonlinux

apps:json結構，apps是一個數組，每個數組成員就是對應一個pm2中運行的應用  
name:應用程序名稱  
args:腳本的參數域
cwd:應用程序所在的目錄  
script:應用程序的腳本路徑  
log_date_format:
node_args:node 的參數域  
error_file:自定義應用程序的錯誤日誌文件  
out_file:自定義應用程序日誌文件  
pid_file:自定義應用程序的pid文件  
instances:  
min_uptime:最小運行時間，這裏設置的是60s即若是應用程序在60s內退出，pm2會認爲程序異常退出，此時觸發重啓max_restarts設置數量  
max_restarts:設置應用程序異常退出重啓的次數，默認15次（從0開始計數）  
cron_restart:定時啓動，解決重啓能解決的問題  
watch:是否啓用監控模式，默認是false。若是設置成true，當應用程序變更時，pm2會自動重載。這裏也能夠設置你要監控的文件。  
merge_logs:  
exec_interpreter:應用程序的腳本類型，這裏使用的shell，默認是nodejs  
exec_mode:應用程序啓動模式，這裏設置的是cluster_mode（集羣），默認是fork  
autorestart:啓用/禁用應用程序崩潰或退出時自動重啓  
vizion:啓用/禁用vizion特性(版本控制)

總結-經常使用命令總結以下：

安裝pm2

npm install -g pm2nginx

啓動應用

pm2 start app.jsc++

列出全部應用

pm2 listgit

查看資源消耗

pm2 monitweb

查看某一個應用狀態

pm2 describe [app id]shell

查看全部日誌

pm2 logsnpm

重啓應用

pm2 restart [app id]json

中止應用

pm2 stop [app id]api

開啓api訪問

pm2 web

安裝pm2-web

安裝軟件

安裝時須要g++，make等軟件，下面的軟件你本身挑（我是剛裝完系統就都裝了）

yum -y install ntpdate lrzsz tree cmake gcc gcc-c++ autoconf l libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel libxslt-devel libtool-ltdl-devel make wget docbook-dtds asciidoc e2fsprogs-devel gd gd-devel openssl openssl-devel lsof git unzip gettext-devel gettext libevent libevent-devel pcre pcre-devel

npm install --unsafe-perm -g pm2-web

  
pm2-web

配置啓動文件

[root@localhost ~]# cat pm2-web-config.json 

{  
    "www": {  
        "host": "localhost",  
        "address": "0.0.0.0",  
        "port": 11111  
    }                           
}

[root@localhost ~]# cat pm2-web-start.sh

  
nohup pm2-web --config pm2-web-config.json >pm2-web.log&

  
[root@localhost ~]# sh +x   pm2-web-start.sh

server {  
        listen 80;  
        server_name pm2-web.xxxx.com;  
        access_log /data/nginx/logs/node-web.xxx.com/node-web.xxxx.com.log main;  
        location / {  
                auth_basic              "node-web monitor";                                                                        
                auth_basic_user_file    /data/nginx/htpasswd.conf;  //設置用戶訪問控制  
                proxy_pass http://192.168.0.xxx:xxxx;  
                proxy_redirect off;  
                proxy_set_header Host $http_host;  
                proxy_set_header X-Real-IP $remote_addr;  
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;  
                proxy_http_version 1.1;  
                proxy_set_header Upgrade $http_upgrade;  
                proxy_set_header Connection "upgrade";  
                proxy_connect_timeout 360;  
                proxy_send_timeout 360;  
                proxy_read_timeout 360;  
        }  
}
