supervisor的简单使用

1、安装

配置好yum源后，yum安装

yum install supervisor

  Debian/Ubuntu可通过apt安装

apt-get install supervisor

pip安装

pip install supervisor

2、基本配置文件

2.1、主配置文件/etc/supervisor下的supervisord.conf

; 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

2.2、启动服务的配置文件/etc/supervisor/conf.d下的wenkong-8084.conf

这个里面可以配置服务的执行位置、执行语句、日志或错误日志输出到指定文件内。

root@ubuntu:/etc/supervisor/conf.d# pwd
/etc/supervisor/conf.d
root@ubuntu:/etc/supervisor/conf.d# cat wenkong-8084.conf 
[program:wenkong-8084]
command=java -jar mainmodule-exec.jar  # 要执行的语句
numprocs=1
directory=/usr/local/wenkong     # 在这个文件目录下执行语句
autostart=true
autorestart=true
startretries=10
redirect_stderr=true
stdout_logfile=/usr/local/wenkong/wenkong.txt   # 日志输出到指定文件
user=root
root@ubuntu:/etc/supervisor/conf.d# 

3、基本操作命令

启动supervisor ： systemctl start supervisor

开机启动supervisor ： systemctl enable supervisor

查看supervisor 下的服务状态 ：supervisorctl status
