#### 一、安装 ####

Linux Binaries下载地址：[https://nodejs.org/dist][https_nodejs.org_dist]

1.  cd [oneinstack][]/src
2.  wget https://nodejs.org/dist/v4.2.4/node-v4.2.4-linux-x64.tar.gz
3.  tar xzf node-v4.2.4-linux-x64.tar.gz
4.  cp node-v4.2.4-linux-x64/bin/node /usr/local/bin/
5.  cp -R node-v4.2.4-linux-x64/lib/node\_modules /usr/local/lib/
6.  ln -s /usr/local/lib/node\_modules/npm/bin/npm-cli.js /usr/local/bin/npm
7.  npm install pm2@latest -g \#安装最新版本pm2模块

PS: 如果你的主机无法连接公网，先找到能连公网的主机安装上面的方法安装pm2，然后拷贝到你要安装的主机。拷贝如下目录：

1.  /usr/local/bin/node
2.  /usr/local/lib/node\_modules

再创建相关软连接

#### 二、PM2常用命令 ####

假设你现在已经写好了一个app.js的文件，需要启动，你可以使用pm2进行管理

#### 1. 启动 ####

1.  \# pm2 start app.js
2.  \# pm2 start app.js --name my-api   \#my-api为PM2进程名称
3.  \# pm2 start app.js -i 0           \#根据CPU核数启动进程个数
4.  \# pm2 start app.js --watch   \#实时监控app.js的方式启动，当app.js文件有变动时，pm2会自动reload

#### 2. 查看进程 ####

1.  \# pm2 list
2.  \# pm2 show 0 或者 \# pm2 info 0  \#查看进程详细信息，0为PM2进程id

#### 3. 监控 ####

1.  \# pm2 monit

#### 4. 停止 ####

1.  \# pm2 stop all  \#停止PM2列表中所有的进程
2.  \# pm2 stop 0    \#停止PM2列表中进程为0的进程

#### 5. 重载 ####

1.  \# pm2 reload all    \#重载PM2列表中所有的进程
2.  \# pm2 reload 0     \#重载PM2列表中进程为0的进程

#### 6. 重启 ####

1.  \# pm2 restart all     \#重启PM2列表中所有的进程
2.  \# pm2 restart 0      \#重启PM2列表中进程为0的进程

#### 7. 删除PM2进程 ####

1.  \# pm2 delete 0     \#删除PM2列表中进程为0的进程
2.  \# pm2 delete all   \#删除PM2列表中所有的进程

#### 8. 日志操作 ####

1.  \# pm2 logs \[--raw\]   \#Display all processes logs in streaming
2.  \# pm2 flush              \#Empty all log file
3.  \# pm2 reloadLogs    \#Reload all logs

#### 9. 升级PM2 ####

1.  \# npm install pm2@lastest -g   \#安装最新的PM2版本
2.  \# pm2 updatePM2                    \#升级pm2

#### 10. 更多命令参数请查看帮助 ####

1.  \# pm2 --help

#### 三、PM2目录结构 ####

默认的目录是：当前用于的家目录下的.pm2目录（此目录可以自定义，请参考：五、自定义启动文件），详细信息如下：

1.  $HOME/.pm2                   \#will contain all PM2 related files
2.  $HOME/.pm2/logs           \#will contain all applications logs
3.  $HOME/.pm2/pids           \#will contain all applications pids
4.  $HOME/.pm2/pm2.log    \#PM2 logs
5.  $HOME/.pm2/pm2.pid    \#PM2 pid
6.  $HOME/.pm2/rpc.sock    \#Socket file for remote commands
7.  $HOME/.pm2/pub.sock   \#Socket file for publishable events
8.  $HOME/.pm2/conf.js       \#PM2 Configuration

#### 四、自定义启动文件 ####

创建一个test.json的示例文件，格式如下：

1.  \{
2.    "apps":
3.      \{
4.        "name": "test",
5.        "cwd": "/data/wwwroot/nodejs",
6.        "script": "./test.sh",
7.        "exec\_interpreter": "bash",
8.        "min\_uptime": "60s",
9.        "max\_restarts": 30,
10.       "exec\_mode" : "cluster\_mode",
11.       "error\_file" : "./test-err.log",
12.       "out\_file": "./test-out.log",
13.       "pid\_file": "./test.pid"
14.       "watch": false
15.     \}
16. \}

说明：

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：应用程序的名称

cwd：应用程序所在的目录

script：应用程序的脚本路径

exec\_interpreter：应用程序的脚本类型，这里使用的shell，默认是nodejs

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）

exec\_mode：应用程序启动模式，这里设置的是cluster\_mode（集群），默认是fork

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

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。

详细参数列表：见附件八

#### 五、实例 ####

已上面的test.json为例

1.  \# cat > /data/wwwroot/nodejs/test.sh << EOF
2.  \#!/bin/bash
3.  **while** :
4.  do
5.      echo "Test" >> 1.log
6.      sleep 5
7.  done
8.  EOF

1.  \# chmod +x test.sh      \#添加执行权限
2.  \# pm2 start test.json    \#启动，如下图：

![pm2_example_start.png][]

1.  \# pm2 list    \#查看pm2进程，如下图：

![pm2_example_list.png][]
