Ubuntu环境安装配置Nodejs与pm2进程守护

# pm2启动进程之后系统重启会丢失，需要保存pm2程序启动列表
pm2 save
# [PM2] Saving current process list...
[PM2] Successfully saved in /home/test/.pm2/dump.pm2

# 踩坑点,如果简单执行pm2 startup机器重启之后进程无法自动恢复,执行pm2 update可恢复,但是需要手动执行.
pm2 startup ubuntu -u myuser --hp /home/myuser/
 
# pm2 startup 创建开机启动脚本
# ubuntu 你服务器使用的平台.ubuntu用户改成ubuntu即可
# -u myuser 使用哪个用户启动
# --hp define home path when generating startup script.用户的家目录.也是放置刚才执行pm2 save 之后产生的dump.pm2 文件的路径
 
# ubuntu环境会生成一串环境环境变量设置代码,复制执行即可实现开机启动

# Install latest PM2 version
$ npm install pm2@latest -g
# Save process list, exit old PM2 & restore all processes
$ pm2 update

# 安装pm2日志分割（前提是已经安装pm2)
pm2 install pm2-logrotate
 
# 查看配置
pm2 conf pm2-logrotate
 
# 配置
$ pm2 set pm2-logrotate:max_size 10M
 
$ pm2 set pm2-logrotate:retain 7
 
$ pm2 set pm2-logrotate:compress false
 
$ pm2 set pm2-logrotate:dateFormat YYYY-MM-DD_HH-mm-ss
 
$ pm2 set pm2-logrotate:workerInterval 30
 
$ pm2 set pm2-logrotate:rotateInterval 10 * * * *
 
$ pm2 set pm2-logrotate:rotateModule true
 

# pm2日志清理
pm2 flush
