pm2运行json文件及pm2-web的配置使用
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/",

]
}[root@node-44 ~]# cat app.json

]
}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
