#### 常用命令： ####

#查看所有服务状态
    supervisorctl status
    #查看单个服务状态
    supervisorctl status　服务名
    #启动/停止/重启服务
    supervisorctl start/stop/restart 服务名

#### 新增一个服务： ####

[program:<服务名>]
    command=<启动命令>
    process_name=%(program_name)s ; process_name expr (default %(program_name)s)
    numprocs=1                    ; number of processes copies to start (def 1)
    directory=<运行目录>                ; directory to cwd to before exec (def no cwd)
    ;umask=022                     ; umask for process (default None)
    ;priority=999                  ; the relative start priority (default 999)
    autostart=true                ; start at supervisord start (default: true)
    autorestart=unexpected        ; whether/when to restart (default: unexpected)
    startsecs=1                   ; number of secs prog must stay running (def. 1)
    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 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=skywell                  ; setuid to this UNIX account to run the program
    ;redirect_stderr=true          ; redirect proc stderr to stdout (default false)
    stdout_logfile=/var/log/<服务名>.log        ; stdout log path, NONE for none; default AUTO
    stdout_logfile_maxbytes=1MB   ; max # logfile bytes b4 rotation (default 50MB)
    stdout_logfile_backups=1     ; # of stdout logfile backups (default 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=/var/log/<服务名>.err        ; 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 (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",HOME="/home/skywell"       ; process environment additions (def no adds)
    serverurl=AUTO                ; override serverurl computation (childutils)

首先添加任务描述文件，在/etc/supervisor目录下新建文件sparkportal.conf，　将上面任务模板内容复制进文件sparkportal.conf中,将<服务名>替换为任务名sparkportal，将<启动命令>替换为node www.js，将<运行目录>替换为程序所在目录/usr/local/sparkportal/bin。

##### sparkportal的配置文件为 #####

[program:sparkportal]
    command=node www.js
    process_name=%(program_name)s ; process_name expr (default %(program_name)s)
    numprocs=1                    ; number of processes copies to start (def 1)
    directory=/usr/local/sparkportal/bin                ; directory to cwd to before exec (def no cwd)
    ;umask=022                     ; umask for process (default None)
    ;priority=999                  ; the relative start priority (default 999)
    autostart=true                ; start at supervisord start (default: true)
    autorestart=unexpected        ; whether/when to restart (default: unexpected)
    startsecs=1                   ; number of secs prog must stay running (def. 1)
    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 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=skywell                  ; setuid to this UNIX account to run the program
    ;redirect_stderr=true          ; redirect proc stderr to stdout (default false)
    stdout_logfile=/var/log/sparkportal.log        ; stdout log path, NONE for none; default AUTO
    stdout_logfile_maxbytes=1MB   ; max # logfile bytes b4 rotation (default 50MB)
    stdout_logfile_backups=1     ; # of stdout logfile backups (default 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=/var/log/sparkportal.err        ; 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 (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",HOME="/home/skywell"       ; process environment additions (def no adds)
    serverurl=AUTO                ; override serverurl computation (childutils)

###### 最小必要配置 ######

[program:easyswoole-xxx-xxx-com]
    #process_name=%(process_num)02d
    command=php /home/www/xx.xxx.com/easyswoole start produce
    autostart=true
    autorestart=true
    user=root
    #numprocs=1
    redirect_stderr=true
    stdout_logfile=/home/www/xxx.xxx.com/Log/supervisor.log

#### 增加任务 ####

supervisorctl update

该命令会将sparkportal.conf所描述的任务启动并纳入管理。然后运用查看任务命令即可查看新增任务的运行状态，如若运行失败，可查看/usr/log目录下的相关日志分析原因。

设置环境变量  
在配置文件找到environment所在行，若没有没有最下面增加environment=变量名="变量值"即可，如果多个环境变量用逗号分隔，例如environment=变量名1=“变量值１”,变量名2=“变量值2”。

将nodejs运行环境设置为生产环境，增加如下代码：

environment=NODE_ENV=production
