pm2运行json文件启动node项目及pm2-web的安装

定义运行配置文件

我们可以预定义一个配置文件，然后制定运行这个配置文件，比如我们定义一个文件app.json，内容如下：

[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/",

      "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",

      "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",

      "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")
                    
                    }

• 然后可以通过,运行这个App。

pm2 start app.json

apps:json结构，apps是一个数组，每一个数组成员就是对应一个pm2中运行的应用  
name:应用程序名称  
args:脚本的参数域
cwd:应用程序所在的目录  
script:应用程序的脚本路径  
log_date_format:
node_args:node 的参数域  
error_file:自定义应用程序的错误日志文件  
out_file:自定义应用程序日志文件  
pid_file:自定义应用程序的pid文件  
instances:  
min_uptime:最小运行时间，这里设置的是60s即如果应用程序在60s内退出，pm2会认为程序异常退出，此时触发重启max_restarts设置数量  
max_restarts:设置应用程序异常退出重启的次数，默认15次（从0开始计数）  
cron_restart:定时启动，解决重启能解决的问题  
watch:是否启用监控模式，默认是false。如果设置成true，当应用程序变动时，pm2会自动重载。这里也可以设置你要监控的文件。  
merge_logs:  
exec_interpreter:应用程序的脚本类型，这里使用的shell，默认是nodejs  
exec_mode:应用程序启动模式，这里设置的是cluster_mode（集群），默认是fork  
autorestart:启用/禁用应用程序崩溃或退出时自动重启  
vizion:启用/禁用vizion特性(版本控制)

总结-常用命令总结如下：

• 安装pm2

npm install -g pm2

• 启动应用

pm2 start app.js

• 列出所有应用

pm2 list

• 查看资源消耗

pm2 monit

• 查看某一个应用状态

pm2 describe [app id]

• 查看所有日志

pm2 logs

• 重启应用

pm2 restart [app id]

• 停止应用

pm2 stop [app id]

• 开启api访问

pm2 web

安装pm2-web

安装软件

安装时需要g++，make等软件，下面的软件你自己挑（我是刚装完系统就都装了）

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

配置启动文件

[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
