supervisord

安装Supervisor
# yum install epel-release
# yum install -y supervisor
# systemctl enable supervisord # 开机自启动
# systemctl start supervisord # 启动supervisord服务

# systemctl status supervisord # 查看supervisord服务状态
# ps -ef|grep supervisord # 查看是否存在supervisord进程
或者执行以下命令：
yum install python-setuptools  #安装easy_install 这个命令的软件包
easy_install supervisor        #安装supervisor

配置Supervisor
mkdir /etc/supervisor
echo_supervisord_conf > /etc/supervisor/supervisord.conf
#编辑supervisor配置文件
vim /etc/supervisor/supervisord.conf
  [include]
  files = /etc/supervisor/conf.d/*.ini

启动supervisor

supervisord -c /etc/supervisor/supervisord.conf 
supervisorctl status
supervisorctl reload              #修改了配置文件需要此操作重载、重启supervisord的服务

supervisorctl -c /etc/supervisord.conf
以上命令进入客户端shell
status    # 查看程序状态
stop xx   # 关闭 xx 程序
start xx  # 启动 xx 程序
restart xx    # 重启 xx 程序
reread    ＃ 读取有更新（增加）的配置文件，不会启动新添加的程序
update    ＃ 重启配置文件修改过的程序

也可以如下在shell直接进行
supervisorctl status
supervisorctl stop xx
supervisorctl start xx
supervisorctl restart xx
supervisorctl reread
supervisorctl update
