elasticsearch,kafka,zookeeper,kibana,elasticsearch-head,logstash，logstash是需要经常重启的，你上了点过滤规则或者修改点啥的，每次都尼玛杀进程，再nohup ，还看不到日志，这太不符合人性了，人性的优点之一就是懒惰。打开web 界面，点一下鼠标解决问题岂不是棒棒哒，还能通过web 界面看看后台日志，故而用supervisor托管
supervisor运行的系统：centos 7
supervisor version：3.3.4
二、安装
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 "^$"
[unix_http_server]
file=/tmp/supervisor.sock ; the path to the socket file
[inet_http_server] ; inet (TCP) server disabled by default #是否开启web 管理界面
port=ip:9001 ; ip_address:port specifier, *:port for all iface #web 访问端口；

password=password ; default is no password (open server) #web 界面访问密码；
[supervisord]

[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[supervisorctl]
serverurl=unix:///tmp/supervisor.sock ; use a unix:// URL for a unix socket #通过UNIX socket连接supervisord，路径与unix_http_server部分的file一致
[include]
files =/etc/supervisor/conf.d/*.conf #引入额外的配置文件 三、编写ELK托管文件

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
