[TOC] ## 管理非daemon啟動方式軟件 >Supervisor（[http://supervisord.org/](http://supervisord.org/)）是用Python開發的一個client/server服務，是Linux/Unix系統下的一個進程管理工具，不支持Windows系統。它可以很方便的監聽、啟動、停止、重啟一個或多個進程。用Supervisor管理的進程，當一個進程意外被殺死，supervisort監聽到進程死后，會自動將它重新拉起，很方便的做到進程自動恢復的功能，不再需要自己寫shell腳本來控制。 >因為Supervisor是Python開發的，安裝前先檢查一下系統否安裝了Python2.4以上版本。下面以CentOS7，Python2.7版本環境下，介紹Supervisor的安裝與配置步聚： ### 1、安裝Python包管理工具（[easy\_install](https://pypi.python.org/pypi/setuptools)） ``` easy_install是setuptools包里帶的一個命令，使用easy_install實際上是在調用setuptools來完成安裝模塊的工作,所以安裝setuptools即可。 ``` ``` wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py -O - | sudo python ``` ### 2、安裝supervisor ``` easy_install supervisor ``` ``` supervisor安裝完成后會生成三個執行程序：supervisortd、supervisorctl、echo_supervisord_conf，分別是supervisor的守護進程服務（用于接收進程管理命令）、客戶端（用于和守護進程通信，發送管理進程的指令）、生成初始配置文件程序。 ``` ### 3、配置 >運行supervisord服務的時候，需要指定supervisor配置文件，如果沒有顯示指定，默認在以下目錄查找： ``` $CWD/supervisord.conf $CWD/etc/supervisord.conf /etc/supervisord.conf /etc/supervisor/supervisord.conf (since Supervisor 3.3.0) ../etc/supervisord.conf (Relative to the executable) ../supervisord.conf (Relative to the executable) ``` ### 相關命令 ``` # 生成配置文件 mkdir /etc/supervisor echo_supervisord_conf > /etc/supervisor/supervisord.conf # 啟動 supervisord -c /etc/supervisor/supervisord.conf # 客戶端命令 * supervisorctl status 查看進程運行狀態 * supervisorctl start 進程名 啟動進程 * supervisorctl stop 進程名 關閉進程 * supervisorctl restart 進程名 重啟進程 * supervisorctl update 重新載入配置文件 * supervisorctl shutdown 關閉supervisord * supervisorctl clear 進程名 清空進程日志 * supervisorctl 進入到交互模式下。使用help查看所有命令。 * start stop restart + all 表示啟動，關閉，重啟所有進程。 * 重啟相關所有進程 * supervisorctl status | grep "swoft-boy-accost-v1-order-create" | awk -F " " '{print $1}' | xargs supervisorctl restart ``` ### 程序配置 ``` [program:queue] # 程序啟動命令 command=php /mnt/hgfs/www/ndlot/think queue:listen # 程序的啟動目錄 directory=/mnt/hgfs/www/ndlot # 日志目錄 需要注意當指定目錄不存在時無法正常啟動，所以需要手動創建目錄（supervisord 會自動創建日志文件） stdout_logfile=/mnt/hgfs/www/ndlot/queue.out # 在 supervisord 啟動的時候也自動啟動 autostart=true # 程序異常退出后自動重啟 autorestart=true # 進程啟動優先級，默認999，值小的優先啟動 priority=999 # 默認為false,進程被殺死時，是否向這個進程組發送stop信號，包括子進程 stopasgroup=true # 默認為false，向進程組發送kill信號，包括子進程 killasgroup=true [program:redis] command=/www/server/redis/src/redis-server /www/server/redis/redis.conf directory=/www/server/redis/ autorestart=true startsecs=3 startretries=3 stdout_logfile=/www/server/panel/plugin/supervisor/log/redis.out.log stderr_logfile=/www/server/panel/plugin/supervisor/log/redis.err.log stdout_logfile_maxbytes=2MB stderr_logfile_maxbytes=2MB user=root priority=999 numprocs=1 process_name=%(program_name)s_%(process_num)02d ``` ### 一般常用配置 ``` process\_name=%(program\_name)s ＃進程名稱，默認是程序名稱 command 啟動程序命令 numprocs=1 ＃進程數量 directory=/tmp ＃路徑 umask=022 ＃掩碼 priority=999 ＃優先級，越大被開起的越早 autorestart=true ＃自動重啟 startsecs=10 ＃啟動等待時間（秒） startretries=3 ＃啟動重試次數 stopsignal=TERM ＃關閉信號 stopwaitsecs=10 ＃關閉前等待時間 user=chrism ＃監控用戶權限 redirect_stderr=false ＃重定向報錯輸出 stdout_logfile=/a/path ＃輸入重定向為日志 stdout_logfile_maxbytes=1MB ＃日志大小 stdout_logfile_backups=10 ＃日志備份 stdout_capture_maxbytes=1MB stderr_logfile=/a/path stderr_logfile_maxbytes=1MB stderr_logfile_backups=10 stderr_capture_maxbytes=1MB environment=A=1,B=2 ＃預定義環境變量 serverurl=AUTO ＃系統URL ``` ### 配置文件 ``` ; Sample supervisor config file. ; ; For more information on the config file, please see: ; http://supervisord.org/configuration.html ; ; Notes: ; - Shell expansion ("~" or "$HOME") is not supported. Environment ; variables can be expanded using this syntax: "%(ENV_HOME)s". ; - Quotes around values are not supported, except in the case of ; the environment= options as shown below. ; - Comments must have a leading space: "a=b ;comment" not "a=b;comment". ; - Command will be truncated if it looks like a config file comment, e.g. ; "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ". ; ; Warning: ; Paths throughout this example file use /tmp because it is available on most ; systems. You will likely need to change these to locations more appropriate ; for your system. Some systems periodically delete older files in /tmp. ; Notably, if the socket file defined in the [unix_http_server] section below ; is deleted, supervisorctl will be unable to connect to supervisord. # 指定了socket file的位置 [unix_http_server] file=/tmp/supervisor.sock ; the path to the socket file ;chmod=0700 ; socket file mode (default 0700) ;chown=nobody:nogroup ; socket file uid:gid owner ;username=user ; default is no username (open server) ;password=123 ; default is no password (open server) ; Security Warning: ; The inet HTTP server is not enabled by default.

It ; should only be bound to localhost or only accessible from within an ; isolated, trusted network. The inet HTTP server does not support any ; form of encryption.
