supervisor安装、使用详解 supervisor是用python写的一个进程管理工具，用来启动，重启，关闭进程。 1 supervisor的安装 pip install supervisor 2 supervisor的配置文件（supervisor安装完毕后，会有一个配置文件supervisord.conf） echo_supervisord_conf 3 我们使用重定向运算符将配置文件定向到/etc路径下（方便管理） echo_supervisord_conf>/etc/supervisord.conf 4 配置文件详解 复制代码 [unix_http_server] file=/tmp/supervisor.sock ; UNIX socket 文件，supervisorctl 会使用 ;chmod=0700 ; socket 文件的 mode，默认是 0700 ;chown=nobody:nogroup ; socket 文件的 owner，格式： uid:gid ;[inet_http_server] ; HTTP 服务器，提供 web 管理界面 ;port=127.0.0.1:9001 ; Web 管理后台运行的 IP 和端口，如果开放到公网，需要注意安全性 ;username=user ; 登录管理后台的用户名 ;password=123 ; 登录管理后台的密码 [supervisord] logfile=/tmp/supervisord.log ; 日志文件，默认是 $CWD/supervisord.log logfile_maxbytes=50MB ; 日志文件大小，超出会 rotate，默认 50MB logfile_backups=10 ; 日志文件保留备份数量默认 10 loglevel=info ; 日志级别，默认 info，其它: debug,warn,trace pidfile=/tmp/supervisord.pid ; pid 文件 nodaemon=false ; 是否在前台启动，默认是 false，即以 daemon 的方式启动 minfds=1024 ; 可以打开的文件描述符的最小值，默认 1024 minprocs=200 ; 可以打开的进程数的最小值，默认 200 ; the below section must remain in the config file for RPC ; (supervisorctl/web interface) to work, additional interfaces may be ; added by defining them in separate rpcinterface: sections [rpcinterface:supervisor] supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface [supervisorctl] serverurl=unix:///tmp/supervisor.sock ; 通过 UNIX socket 连接 supervisord，路径与 unix_http_server 部分的 file 一致 ;serverurl=http://127.0.0.1:9001 ; 通过 HTTP 的方式连接 supervisord ; 包含其他的配置文件 [include] files = relative/directory/*.ini ; 可以是 *.conf 或 *.ini 复制代码 5 进程Program配置 复制代码 [program:soc_server] directory = /var/www/html/ichat ; 程序的启动目录 command = php soc_server.php start ; 启动命令，可以看出与手动在命令行启动的命令是一样的 autostart = true ; 在 supervisord 启动的时候也自动启动 startsecs = 5 ; 启动 5 秒后没有异常退出，就当作已经正常启动了 autorestart = true ; 程序异常退出后自动重启 startretries = 3 ; 启动失败自动重试次数，默认是 3 user = root ; 用哪个用户启动 redirect_stderr = true ; 把 stderr 重定向到 stdout，默认 false stdout_logfile_maxbytes = 20MB ; stdout 日志文件大小，默认 50MB stdout_logfile_backups = 20 ; stdout 日志文件备份数 ; stdout 日志文件，需要注意当指定目录不存在时无法正常启动，所以需要手动创建目录（supervisord 会自动创建日志文件） stdout_logfile = /data/logs/soc_server_stdout.log ; 可以通过 environment 来添加需要的环境变量，一种常见的用法是修改 PYTHONPATH ; environment=PYTHONPATH=$PYTHONPATH:/path/to/somewhere 复制代码 复制代码 [program:web_server] directory = /var/www/html/ichat ; 程序的启动目录 command = php web_server.php start ; 启动命令，可以看出与手动在命令行启动的命令是一样的 autostart = true ; 在 supervisord 启动的时候也自动启动 startsecs = 5 ; 启动 5 秒后没有异常退出，就当作已经正常启动了 autorestart = true ; 程序异常退出后自动重启 startretries = 3 ; 启动失败自动重试次数，默认是 3 user = root ; 用哪个用户启动 redirect_stderr = true ; 把 stderr 重定向到 stdout，默认 false stdout_logfile_maxbytes = 20MB ; stdout 日志文件大小，默认 50MB stdout_logfile_backups = 20 ; stdout 日志文件备份数 ; stdout 日志文件，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 = /data/logs/soc_server_stdout.log ; 可以通过 environment 来添加需要的环境变量，一种常见的用法是修改 PYTHONPATH ; environment=PYTHONPATH=$PYTHONPATH:/path/to/somewhere 复制代码 复制代码 [program:soc_server] command=php /var/www/html/ichat/soc_server.php start process_name=%(program_name)s ; process_name expr (default %(program_name)s) numprocs=1 ; number of processes copies to start (def 1) 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) [program:web_server] command=php /var/www/html/ichat/web_server.php start process_name=%(program_name)s ; process_name expr (default %(program_name)s) numprocs=1 ; number of processes copies to start (def 1) 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) [group:ichat_soc] programs=soc_server priority=999 [group:ichat_web] programs=web_server priority=999 复制代码 推荐将各个进程配置放到单独的文件中，然后通过[include]配置项引用 [include] ;files = relative/directory/*.ini files = /etc/supervisor/*.conf 6 supervisor服务启动 supervisord -c /etc/supervisord.conf 7 supervisor服务客户端管理 supervisorctl status //查看状态 supervisorctl start web_server //开启一个进程 supervisorctl stop web_server //停止一个进程 supervisorctl restart web_server //重启一个进程 supervisorctl reread //重新加载配置 supervisorctl update //更新启动列表 8 supervisor web管理界面 ;[inet_http_server] ; HTTP 服务器，提供 web 管理界面 ;port=127.0.0.1:9001 ; Web 管理后台运行的 IP 和端口，如果开放到公网，需要注意安全性 ;username=user ; 登录管理后台的用户名 ;password=123 ; 登录管理后台的密码 在浏览器中输入http://127.0.0.1:9001，可进入web管理界面
