[TOC] ## 管理非daemon启动方式软件 >Supervisor（[http://supervisord.org/](http://supervisord.org/)）是用Python开发的一个client/server服务，是Linux/Unix系统下的一个进程管理工具，不支持Windows系统。它可以很方便的监听、启动、停止、重启一个或多个进程。用Supervisor管理的进程，当一个进程意外被杀死，supervisort监听到进程死后，会自动将它重新拉起，很方便的做到进程自动恢复的功能，不再需要自己写shell脚本来控制。 >因为Supervisor是Python开发的，安装前先检查一下系统否安装了Python2.4以上版本。下面以CentOS7，Python2.7版本环境下，介绍Supervisor的安装与配置步聚： ### 1、安装Python包管理工具（[easy\_install](https://pypi.python.org/pypi/setuptools)） ``` easy_install是setuptools包里带的一个命令，使用easy_install实际上是在调用setuptools来完成安装模块的工作,所以安装setuptools即可。 ``` ``` wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py -O - | sudo python ``` ### 2、安装supervisor ``` easy_install supervisor ``` ``` supervisor安装完成后会生成三个执行程序：supervisortd、supervisorctl、echo_supervisord_conf，分别是supervisor的守护进程服务（用于接收进程管理命令）、客户端（用于和守护进程通信，发送管理进程的指令）、生成初始配置文件程序。 ``` ### 3、配置 >运行supervisord服务的时候，需要指定supervisor配置文件，如果没有显示指定，默认在以下目录查找： ``` $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) ``` ### 相关命令 ``` # 生成配置文件 mkdir /etc/supervisor echo_supervisord_conf > /etc/supervisor/supervisord.conf # 启动 supervisord -c /etc/supervisor/supervisord.conf # 客户端命令 * supervisorctl status 查看进程运行状态 * supervisorctl start 进程名 启动进程 * supervisorctl stop 进程名 关闭进程 * supervisorctl restart 进程名 重启进程 * supervisorctl update 重新载入配置文件 * supervisorctl shutdown 关闭supervisord * supervisorctl clear 进程名 清空进程日志 * supervisorctl 进入到交互模式下。使用help查看所有命令。 * start stop restart + all 表示启动，关闭，重启所有进程。 * 重启相关所有进程 * supervisorctl status | grep "swoft-boy-accost-v1-order-create" | awk -F " " '{print $1}' | xargs supervisorctl restart ``` ### 程序配置 ``` [program:queue] # 程序启动命令 command=php /mnt/hgfs/www/ndlot/think queue:listen # 程序的启动目录 directory=/mnt/hgfs/www/ndlot # 日志目录 需要注意当指定目录不存在时无法正常启动，所以需要手动创建目录（supervisord 会自动创建日志文件） stdout_logfile=/mnt/hgfs/www/ndlot/queue.out # 在 supervisord 启动的时候也自动启动 autostart=true # 程序异常退出后自动重启 autorestart=true # 进程启动优先级，默认999，值小的优先启动 priority=999 # 默认为false,进程被杀死时，是否向这个进程组发送stop信号，包括子进程 stopasgroup=true # 默认为false，向进程组发送kill信号，包括子进程 killasgroup=true [program:redis] command=/www/server/redis/src/redis-server /www/server/redis/redis.conf directory=/www/server/redis/ autorestart=true startsecs=3 startretries=3 stdout_logfile=/www/server/panel/plugin/supervisor/log/redis.out.log stderr_logfile=/www/server/panel/plugin/supervisor/log/redis.err.log stdout_logfile_maxbytes=2MB stderr_logfile_maxbytes=2MB user=root priority=999 numprocs=1 process_name=%(program_name)s_%(process_num)02d ``` ### 一般常用配置 ``` process\_name=%(program\_name)s ＃进程名称，默认是程序名称 command 启动程序命令 numprocs=1 ＃进程数量 directory=/tmp ＃路径 umask=022 ＃掩码 priority=999 ＃优先级，越大被开起的越早 autorestart=true ＃自动重启 startsecs=10 ＃启动等待时间（秒） startretries=3 ＃启动重试次数 stopsignal=TERM ＃关闭信号 stopwaitsecs=10 ＃关闭前等待时间 user=chrism ＃监控用户权限 redirect_stderr=false ＃重定向报错输出 stdout_logfile=/a/path ＃输入重定向为日志 stdout_logfile_maxbytes=1MB ＃日志大小 stdout_logfile_backups=10 ＃日志备份 stdout_capture_maxbytes=1MB stderr_logfile=/a/path stderr_logfile_maxbytes=1MB stderr_logfile_backups=10 stderr_capture_maxbytes=1MB environment=A=1,B=2 ＃预定义环境变量 serverurl=AUTO ＃系统URL ``` ### 配置文件 ``` ; Sample supervisor config file. ; ; For more information on the config file, please see: ; http://supervisord.org/configuration.html ; ; Notes: ; - Shell expansion ("~" or "$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.
