首先添加任务描述文件，在/etc/supervisor目录下新建文件sparkportal.conf， 将上面任务模板内容复制进文件sparkportal.conf中,将<服务名>替换为任务名sparkportal，将<启动命令>替换为node www.js，将<运行目录>替换为程序所在目录/usr/local/sparkportal/bin。
sparkportal的配置文件为
[program:sparkportal]
command=node www.js
process_name=%(program_name)s ; process_name expr (default %(program_name)s)
numprocs=1 ; number of processes copies to start (def 1)
directory=/usr/local/sparkportal/bin ; directory to cwd to before exec (def no cwd)
;umask=022 ; umask for process (default None)
;priority=999 ; the relative start priority (default 999)
autostart=true ; start at supervisord start (default: true)

- 增加任务
supervisorctl update
# supervisorctl update
sparkportal: added process group
该命令会将sparkportal.conf所描述的任务启动并纳入管理。然后运用查看任务命令即可查看新增任务的运行状态，如若运行失败，可查看/usr/log目录下的相关日志分析原因。
设置环境变量
在配置文件找到environment所在行，若没有没有最下面增加environment=变量名=“变量值"即可，如果多个环境变量用逗号分隔，例如environment=变量名1="变量值１",变量名2="变量值2"。
将nodejs运行环境设置为生产环境，增加如下代码：
environment=NODE_ENV=production
注意事项
- 被监控的进程 down 后，是否自动将其拉起由 autorestart 参数决定( true 表示无条件拉起)
- 进程是否随着 supervisor 进程一起启动由 autostart 决定
- 程序如果对用户有特定要求（eg: 执行 git 命令），则需要指定 user 参数
