First, talk about cause and effect
elasticsearch, kafka, zookeeper, kibana, elasticsearch-head, logstash, logstash is often required to restart you on the point of filtering rules or modify Diansha of every Nima kill the process, and then nohup, do not see the log, this too is not consistent with human nature, and one of the advantages of human nature is lazy. Open the web interface, mouse click would not solve the problem Bang Bang da, but also look at the backlog through the web interface, and therefore is hosted by supervisor
Operating system supervisor: centos 7
supervisor version：3.3.4
Second, the installation
用easy_install 安装pip
easy_install pip
#之后通过pip 安装supervisor
pip install supervisor
#为supervisor创建工作目录与配置文件目录并且赋予该目录755 的权限；
mkdir -m 755 -p /etc/supervisor/conf.d
#通过supervisor 提供的 echo_supervisord_conf 命令生成默认配置文件
echo_supervisord_conf > /etc/supervisor/supervisord.conf
#通过cat 命令查看配置文件是否生成；
cat /etc/supervisor/supervisord.conf |grep -v "^;" |grep -v "^$"

参考启动的程序
supervisor status
第一行是自定义的名字； 第二个是运行状态，第三是pid ，第三行是启动时间
ELK 服务端程序启停自动管理工具之supervisor
#关闭supervisor
supervisorctl shutdown
#重新载入supervisor，重新载入supervisor，在这里相当于重启supervisor服务，里面的服务也会跟着重新启动
supervisor reload
#添加/删除 要管理服务，当你修改了配置文件，可以直接通过update 方式升级即可
supervisor update
#通过命令方式启动所有服务或者单个服务
supervisorctl start all
supervisorctl start service_name
#关闭服务
supervisorctl stop all
supervisorctl stop service_name
#重启所有服务或者单个服务
supervisorctl restart all
supervistorctl restart service_name
