supervisor 监控进程

supervisor监控进程

• 安装
  sudo apt-get install supervisor
• 创建socket文件
  sudo touch var/run/supervisor.sock

• 配置文件

  ; 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/supervisor/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[program:test_deploy] ;program目录 directory = /home/lhy/go/src/tmp/ ;启动进程命令 command= /home/lhy/go/src/tmp/test_deploy startsecs=5 startretries=3

• 测试程序(被监控进程)

  package main
  import("time""log""os"
  )
  func main(){//定时触发d:=time.After(2*time.Second)file:="deploy.log"logfile,err:=os.Create(file)defer logfile.Close()if err!=nil{return}debug:=log.New(logfile,"[DEBUG]",log.LstdFlags)for{//记录到deploy.log文件中select{case <-d:log.Println(time.Now())debug.Println(time.Now())d=time.After(2*time.Second)}}
  }
