基础操作

安装pm2

1yarn global add pm2
2pm2 install pm2-logrotate  #可选，日志需要做轮转就要安装，配置方式参考https://github.com/keymetrics/pm2-logrotate
3pm2 completion install

启动一个任务

pm2 start app.js

作业列表

pm2 ls

删除作业

pm2 delete app

作业启动与停止

1pm2 stop app
2pm2 start app
3pm2 restart app
4pm2 restart ecosystem.config.js --update-env

生成作业配置模板

pm2 init

作业列表的导入和导出

1pm2 save
2pm2 resurrect

监控与日志

1pm2 logs app
2pm2 flush     #清空所有应用的日志
3pm2 monit

在配置文件中指定日志存放位置

1module.exports = {
2  apps: [{
3      name: 'app',
4      script: 'app.js',
5      output: './out.log',
6      error: './error.log',
7	    log: './combined.outerr.log',
8    }]
9}

集群模式下使用merge参数融合日志文件

1module.exports = {
2  apps: [{
3      name: 'app',
4      script: 'app.js',
5      output: './out.log',
6      error: './error.log',
7      merge_logs: true,
8    }]
9}

集群模式

1pm2 start app.js -i 4
2pm2 start app.js -i max

开发工具

开启文件监控

1module.exports = {
2  apps : [{
3    name: "app",
4    script: "./app.js",
5    watch: true,
6  }]
7}

CLI命令行监控

pm2 start app.js --watch

pm2可以作为静态服务器

pm2 serve ./nodejs/ 6060

配置文件启动静态服务

1module.exports = {
2  apps: [{
3    name: "static-file",
4    script: "serve",
5    env: {
6      PM2_SERVE_PATH: ".",
7      PM2_SERVE_PORT: 8080,
8    },
9  }]
10}

使用SSH发布

1ssh-keygen -t rsa
2ssh-copy-id node@myserver.com

配置作业文件

1module.exports = {
2  apps: [{
3    name: "app",
4    script: "app.js"
5  }],
6  deploy: {
7    production: {
8      key: "/path/to/some.pem",
9      user: "ubuntu",
10      host: ["192.168.0.13"],
11      ssh_options: "StrictHostKeyChecking=no",
12      ref: "origin/master",
13      repo: "git@github.com:Username/repository.git",
14      path: "/var/www/my-repository",
15      pre-setup: "apt-get install git ; ls -la",
16      post-setup: "ls -la",
17      pre-deploy-local: "echo 'This is a local executed command'"
18      post-deploy: "npm install",
19    },
20  }
21}

开始部署

1pm2 deploy production setup
2pm2 deploy production update  #更新
3pm2 deploy production revert 1 #回滚
4pm2 deploy production exec "pm2 reload all" #执行远程命令
