Centos7 使用 supervisor 管理进程

一、安装

//直接使用pip安装(pip的安装 http://www.cnblogs.com/yxhblogs/p/8971251.html)
pip install supervisor

二、配置

//运行echo_supervisord_conf 命令重定向到一个配置文件
echo_supervisord_conf > /etc/supervisord.conf

三、修改配置文件

//创建一个目录
mkdir /etc/supervisor.d

//把/etc/supervisord.conf 里 include 部分的的配置修改一下，改为如下：
[include]
files = /etc/supervisor.d/*.conf

四、program 配置

[root@localhost supervisord.d]# cat test.conf 
;[program:theprogramname]
;command=/bin/cat              ; the program (relative uses PATH, can take args)  //启动命令，与手动在命令行启动的命令是一样的
;process_name=%(program_name)s ; process_name expr (default %(program_name)s) 
;numprocs=1                    ; number of processes copies to start (def 1)
;directory=/var/tmp                ; directory to cwd to before exec (def no cwd) //程序的启动目录
;umask=022                     ; umask for process (default None)
;priority=999                  ; the relative start priority (default 999)
;autostart=true                ; start at supervisord start (default: true) //在 supervisord 启动的时候也自动启动
;startsecs=1                   ; # of secs prog must stay up to be running (def. 1)   //启动 1 秒后没有异常退出，就当作已经正常启动了
;startretries=3                ; max # of serial start failures when starting (default 3) //启动失败自动重试次数，默认是 3
;autorestart=unexpected        ; when to restart if exited after running (def: unexpected)
;exitcodes=0,2                 ; 'expected' exit codes used with autorestart (default 0,2)
;stopsignal=QUIT               ; signal used to kill process (default TERM)
;stopwaitsecs=10               ; max num secs to wait b4 SIGKILL (default 10)
;stopasgroup=false             ; send stop signal to the UNIX process group (default false)
;killasgroup=false             ; SIGKILL the UNIX process group (def false)
;user=chrism                   ; setuid to this UNIX account to run the program //用哪个用户启动
;redirect_stderr=true          ; redirect proc stderr to stdout (default false) //把 stderr 重定向到 stdout，默认 false
;stdout_logfile=/a/path        ; stdout log path, NONE for none; default AUTO
;stdout_logfile_maxbytes=1MB   ; max # logfile bytes b4 rotation (default 50MB) //stdout 日志文件大小，默认 50MB
;stdout_logfile_backups=10     ; # of stdout logfile backups (0 means none, default 10) //stdout 日志文件备份数 , 默认10
;stdout_capture_maxbytes=1MB   ; number of bytes in 'capturemode' (default 0)
;stdout_events_enabled=false   ; emit events on stdout writes (default false)
;stderr_logfile=/a/path        ; stderr log path, NONE for none; default AUTO
;stderr_logfile_maxbytes=1MB   ; max # logfile bytes b4 rotation (default 50MB)
;stderr_logfile_backups=10     ; # of stderr logfile backups (0 means none, default 10)
;stderr_capture_maxbytes=1MB   ; number of bytes in 'capturemode' (default 0)
;stderr_events_enabled=false   ; emit events on stderr writes (default false)
;environment=A="1",B="2"       ; process environment additions (def no adds)
;serverurl=AUTO                ; override serverurl computation (childutils)

五、启动

//启动supervisor
supervisord -c /etc/supervisord.conf
