注：Supervisor目前只能运行在python2.x
一、安装
1.1、使用apt-get安装
$ sudo apt-get install supervisor
1.2、使用pip安装
$ sudo pip install supervisor
安装之后：会产生三个可执行程序，supervisord supervisorctl echo_supervisor_conf，这三个程序分别是：守护程序、supervisor客户端、创建默认supervisor的配置文件。
二、配置
2.1、使用apt-get安装后的配置
对于使用apt-get1安装成功后，默认的配置都已经生成，配置文件路径为：
$ /etc/supervisor
该目录下所有文件：
$ ls
conf.d supervisord.conf
其中supervisord.conf是supervisord的配置文件
conf.d是一个目录，我们可以将我们的进程配置移到改目录下
分文件组织
supervisord.conf配置文件的内容为：
; supervisor config file
[unix_http_server]
file=/var/run/supervisor.sock ; (the path to the socket file)
chmod=0700 ; sockef file mode (default 0700)
[supervisord]
logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
childlogdir=/var/log/supervisor ; ('AUTO' child log dir, default $TEMP)
; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[supervisorctl]
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL for a unix socket
; The [include] section can just contain the "files" setting. This
; setting can list multiple files (separated by whitespace or
; newlines). It can also contain wildcards. The filenames are
; interpreted as relative to this file. Included files *cannot*
; include files themselves.
[include]
files = /etc/supervisor/conf.d/*.conf
在conf.d文件夹下创建文件
service-evernote.conf
[program:service-evernote]
autorestart=True
redirect_stderr=True
command=/opt/services/evernote/evernote/bin/dock-server dock_evernote -s gevent -b 0.0.0.0:5000
user=root
autostart=True
directory=/opt/services/evernote/evernote
stdout_logfile=/opt/services/evernote/evernote/evernote.log
执行
sudo supervisorctl
查看运行的服务
配置文件加载
sudo supervisorctl reload
