注意由于supervisor不能监控后台程序,所以command执行的命令都需要放前台执行，比如nginx：command = /usr/local/bin/nginx -g ‘daemon off;’

说下这个工具的好处：

管理你的进程，异常终止自动重启服务进程机器关机，开机也自动启动服务进程集中管理，可以批量重启服务进程安装supervisor

yum install epel-releaseyum install -y supervisor

systemctl enable supervisord 开机启动

systemctl start supervisord 启动服务

编辑配置文件/etc/supervisord.conf

踩坑：

1.注意;分号是注释，一开始配置没搞明白，发现怎么都无法登陆web管理2.zookeeper 执行需要环境变量3.使用[include]无法识别配置文件，我把redis、jar、zookeeper三个配置文件拷贝到/etc/supervisord.conf下，才执行成功，启动服务的时候是用的这个配置文件，下图web管理页面supervisor也可以使用命令管理supervisorctl

status #查看程序状态

stop name #关闭name程序

start name #启动name程序
