 supervisor服务客户端管理

; Sample supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html
;
; Notes:
;  - Shell expansion ("~" or "$HOME") is not supported.  Environment
;    variables can be expanded using this syntax: "%(ENV_HOME)s".
;  - Quotes around values are not supported, except in the case of
;    the environment= options as shown below.
;  - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
;  - Command will be truncated if it looks like a config file comment, e.g.
;    "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".

supervisor安装、使用详解
supervisor是用python写的一个进程管理工具，用来启动，重启，关闭进程。

 supervisor的安装

pip install supervisor

 supervisor的配置文件（supervisor安装完毕后，会有一个配置文件supervisord.conf）

echo_supervisord_conf

 我们使用重定向运算符将配置文件定向到/etc路径下（方便管理）

echo_supervisord_conf>/etc/supervisord.conf

 配置文件详解

复制代码
[unix_http_server]
file=/tmp/supervisor.sock ; UNIX socket 文件，supervisorctl 会使用
;chmod= ; socket 文件的 mode，默认是
;chown=nobody:nogroup ; socket 文件的 owner，格式： uid:gid

;[inet_http_server] ; HTTP 服务器，提供 web 管理界面
;port=127.0.0.1: ; Web 管理后台运行的 IP 和端口，如果开放到公网，需要注意安全性
;username=user ; 登录管理后台的用户名
;password= ; 登录管理后台的密码

[supervisord]
logfile=/tmp/supervisord.log ; 日志文件，默认是 $CWD/supervisord.log
logfile_maxbytes=50MB ; 日志文件大小，超出会 rotate，默认 50MB
logfile_backups= ; 日志文件保留备份数量默认
loglevel=info ; 日志级别，默认 info，其它: debug,warn,trace
pidfile=/tmp/supervisord.pid ; pid 文件
nodaemon=false ; 是否在前台启动，默认是 false，即以 daemon 的方式启动
minfds= ; 可以打开的文件描述符的最小值，默认
minprocs= ; 可以打开的进程数的最小值，默认 

; 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:///tmp/supervisor.sock ; 通过 UNIX socket 连接 supervisord，路径与 unix_http_server 部分的 file 一致
;serverurl=http://127.0.0.1:9001 ; 通过 HTTP 的方式连接 supervisord

; 包含其他的配置文件

推荐将各个进程配置放到单独的文件中，然后通过[include]配置项引用

[include]
;files = relative/directory/*.ini
files = /etc/supervisor/*.conf
6 supervisor服务启动

supervisord -c /etc/supervisord.conf

7 supervisor服务客户端管理

supervisorctl status //查看状态

supervisorctl start web_server //开启一个进程

supervisorctl stop web_server //停止一个进程

supervisorctl restart web_server //重启一个进程

supervisorctl reread //重新加载配置

supervisorctl update //更新启动列表

8 supervisor web管理界面

;[inet_http_server] ; HTTP 服务器，提供 web 管理界面
;port=127.0.0.1:9001 ; Web 管理后台运行的 IP 和端口，如果开放到公网，需要注意安全性
;username=user ; 登录管理后台的用户名
;password=123 ; 登录管理后台的密码
在浏览器中输入http://127.0.0.1:9001，可进入web管理界面
