# **后台定时任务（pm2管理）**

> 本项目部分定时任务用nodejs的pm2管理，代码位于后台`CronController`
>
> (另一部分在trunk/api/protected/tasks目录,未采用pm2管理)


### **安装pm2**

    sudo npm install -g pm2

### **依赖于可执行文件**

    sudo chmod +x /data/webapps/test-shoes-admin.funfet.com/cli.php

### **环境注意事项**

> 由于服务器环境配置的问题，PHP和PM2都要用sudo，否则redis扩展会读取不到

### **任务列表**

    sudo pm2 list

### **查看某个明细**

    sudo pm2 info Shoes-UpdateCommentLikeNum
    tailf -n 100 ~/.pm2/logs/Shoes-UpdateCommentLikeNum-out.log
    sudo pm2 log Shoes-UpdateCommentLikeNum

### **重启某个任务**

    sudo pm2 restart Shoes-UpdateCommentLikeNum

### **日志目录（请善用pm2 info）**

    /home/oujia/.pm2/logs/

### **日志分割**

- 安装模块

    > sudo pm2 install pm2-logrotate

- 配置分割参数

    > - pm2 set pm2-logrotate:retain 50
    > - pm2 set pm2-logrotate:max_size 200M
    > - pm2 set pm2-logrotate:compress true
    > - pm2 set pm2-logrotate:workerInterval 5
    > - pm2 set pm2-logrotate:rotateModule true
    > - pm2 set pm2-logrotate:rotateInterval 0 0 * * *
    > - pm2 set pm2-logrotate:dateFormat YYYY-MM-DD_HH-mm-ss

- 停止日志切割
    > sudo pm2 stop pm2-logrotate

- 手动清理日志
    > pm2 flush 

- 对于pm2-logrotate过多占用CPU的问题

    >
    > 可能刚好看到日志正在压缩...
    > 
    > 如果持续占用，可以检查下pm2-logrotate的三个参数:compress, max_size, retain
    >
    > 参考 <https://github.com/keymetrics/pm2-logrotate/issues/66>

### **保存列表快照**

    sudo pm2 save

### **恢复列表快照**

    sudo pm2 resurrect

### **干掉所有任务,重来**

    sudo pm2 kill

## **正式环境(47.106.73.57)**

- PM2安装：

    > 参考：https://github.com/nodesource/distributions/blob/master/README.md#debinstall
    >
    >     curl -fsSL https://deb.nodesource.com/setup_14.x | sudo -E bash -
    sudo apt-get install -y nodejs

- 正式环境部署命令集

    > PM2部署命令类似于测试环境，把命令里目录的"test-"去掉，并修改环境参数为 --env=form

- 其它优化建议

    > pm2可以设置 --restart-delay <毫秒数> 来控制进程重启间隔。
    > 
    > 这样就可以考虑把部分PHP代码的sleep去掉
