CentOS上安装Supervisor

安装

部署项目从Ubuntu转战到CentOS, 使用yum命令安装supervisor后，发现无法正常使用，因此只有使用pip安装.

$ sudo pip install supervisor

配置supervisor

1. 添加配置文件

   $ sudo mkdir /etc/supervisor
   $ sudo mkdir /etc/supervisor/conf.d
   # 添加如下配置文件
   $ cat /etc/supervisor/supervisord.conf
   [unix_http_server]
   file=/var/tmp/supervisor.sock    ; (the path to the socket file)
   chmod=0700                       ; sockef file mode (default 0700)
   
   ; 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
   
   [supervisord]
   http_port=/var/run/supervisor.sock ; (default is to run a UNIX domain socket server)
   ;http_port=127.0.0.1:9001  ; (alternately, ip_address:port specifies AF_INET)
   ;sockchmod=0700              ; AF_UNIX socketmode (AF_INET ignore, default 0700)
   ;sockchown=nobody.nogroup     ; AF_UNIX socket uid.gid owner (AF_INET ignores)
   ;umask=022                   ; (process file creation umask;default 022)
   logfile=/data/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
   logfile_maxbytes=50MB       ; (max main logfile bytes b4 rotation;default 50MB)
   logfile_backups=10          ; (num of main logfile rotation backups;default 10)
   loglevel=debug              ; (logging level;default info; others: debug,warn)
   pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
   nodaemon=false              ; (start in foreground if true;default false)
   minfds=1024                 ; (min. avail startup file descriptors;default 1024)
   minprocs=200                ; (min. avail process descriptors;default 200)
   childlogdir=/data/log/supervisor ; ('AUTO' child log dir, default $TEMP)
   
   ;nocleanup=true              ; (don't clean up tempfiles at start;default false)
   ;http_username=user          ; (default is no username (open system))
   ;http_password=123           ; (default is no password (open system))
   ;user=chrism                 ; (default is current user, required if root)
   ;directory=/tmp              ; (default is not to cd during start)
   ;environment=KEY=value       ; (key value pairs to add to environment)
   
   [supervisorctl]
   serverurl=unix:///var/tmp/supervisor.sock ; use a unix:// URL  for a unix socket
   ;serverurl=http://127.0.0.1:9001 ; use an http:// url to specify an inet socket
   ;username=chris              ; should be same as http_username if set
   ;password=123                ; should be same as http_password if set
   ;prompt=mysupervisor         ; cmd line prompt (default "supervisor")
   
   ; The below sample program section shows all possible program subsection values,
   ; create one or more 'real' program: sections to be able to control them under
   ; supervisor.
   
   ;[program:theprogramname]
   ;command=/bin/cat            ; the program (relative uses PATH, can take args)
   ;priority=999                ; the relative start priority (default 999)
   ;autostart=true              ; start at supervisord start (default: true)
   ;autorestart=true            ; retstart at unexpected quit (default: true)
   ;startsecs=10                ; number of secs prog must stay running (def. 10)
   ;startretries=3              ; max # of serial start failures (default 3)
   ;exitcodes=0,2               ; 'expected' exit codes for process (default 0,2)
   ;stopsignal=QUIT             ; signal used to kill process (default TERM)
   ;stopwaitsecs=10             ; max num secs to wait before SIGKILL (default 10)
   ;user=chrism                 ; setuid to this UNIX account to run the program
   ;log_stdout=true             ; if true, log program stdout (default true)
   ;log_stderr=true             ; if true, log program stderr (def false)
   ;logfile=/var/log/cat.log    ; child log path, use NONE for none; default AUTO
   ;logfile_maxbytes=1MB        ; max # logfile bytes b4 rotation (default 50MB)
   ;logfile_backups=10          ; # of logfile backups (default 10)
   
   [include]
   files = /etc/supervisor/conf.d/*.conf
   

项目的配置文件写入 /etc/supervisor/conf.d/目录即可

添加开机启动

# 添加如下配置文件
$ cat /etc/init.d/supervisord

$ sudo chkconfig --add supervisord
$ sudo chkconfig supervisord on
$ sudo service supervisord start
