进程管理supervisor

安装
yum -y install supervisor
建议用yum安装，自动生成服务文件/usr/lib/systemd/system/supervisord.service
pip install supervisor

卸载

pip uninstall supervisoryum uninstall supervisor

配置文件
自动生成配置文件/etc/supervisord.conf

子进程路径/etc/supervisord.d/
服务配置文件/usr/lib/systemd/system/supervisord.service

基本命令

supervisord -c supervisord.conf                             通过配置文件启动supervisorsupervisorctl -c supervisord.conf status                    察看supervisor的状态supervisorctl -c supervisord.conf reload                    重新载入 配置文件supervisorctl -c supervisord.conf start [all]|[appname]     启动指定/所有 supervisor管理的程序进程supervisorctl -c supervisord.conf stop [all]|[appname]       关闭指定/所有 supervisor管理的程序进程

web界面操作

需要在supervisor的配置文件里添加[inet_http_server]选项组：之后可以通过http://127.0.0.1:9001来访问控制子线程的管理。[inet_http_server]         ; inet (TCP) server disabled by defaultport=127.0.0.1:9001        ; (ip_address:port specifier, *:port for all iface)username=user              ; (default is no username (open server))password=123               ; (default is no password (open server))

开机自启
开机自启：systemctl enable supervisord.service
其他命令: systemctl start/restart/stop/status supervisord.service
