三、Supervisor管理

Supervisord安装完成后有两个可用的命令行supervisor和supervisorctl。

启动Supervisord
# supervisord
启动时指定配置文件
# supervisord -c /etc/supervisord.conf

# supervisord --help
supervisord -- run a set of applications as daemons.

Usage: /usr/bin/supervisord [options]

Options:
-c/--configuration FILENAME -- configuration file
-n/--nodaemon -- run in the foreground (same as 'nodaemon true' in config file)
-h/--help -- print this usage message and exit
-v/--version -- print supervisord version number and exit
-u/--user USER -- run supervisord as this user (or numeric uid)
-m/--umask UMASK -- use this umask for daemon subprocess (default is 022)
-d/--directory DIRECTORY -- directory to chdir to when daemonized
-l/--logfile FILENAME -- use FILENAME as logfile path
-y/--logfile_maxbytes BYTES -- use BYTES to limit the max size of logfile
-z/--logfile_backups NUM -- number of backups to keep when max bytes reached
-e/--loglevel LEVEL -- use LEVEL as log level (debug,info,warn,error,critical)
-j/--pidfile FILENAME -- write a pid file for the daemon process to FILENAME
-i/--identifier STR -- identifier used for this instance of supervisord
-q/--childlogdir DIRECTORY -- the log directory for child process logs
-k/--nocleanup --  prevent the process from performing cleanup (removal of
                   old automatic child log files) at startup.
-a/--minfds NUM -- the minimum number of file descriptors for start success
-t/--strip_ansi -- strip ansi escape codes from process output
--minprocs NUM  -- the minimum number of processes available for start success
--profile_options OPTIONS -- run supervisord under profiler and output
                             results based on OPTIONS, which  is a comma-sep'd
                             list of 'cumulative', 'calls', and/or 'callers',
                             e.g. 'cumulative,callers')

# supervisorctl
appgroup:wapp                    RUNNING   pid 42981, uptime 0:01:45
appgroup:wfapp                   RUNNING   pid 42982, uptime 0:01:45
cardapi                          RUNNING   pid 33133, uptime 1:02:32
cobar                            RUNNING   pid 6761, uptime 22:43:42
gearmand                         RUNNING   pid 6743, uptime 22:43:53
memcached                        RUNNING   pid 6728, uptime 22:44:05
supervisor> help
default commands (type help <topic>):
=====================================
add    clear  fg        open  quit    remove  restart   start   stop  update 
avail  exit   maintail  pid   reload  reread  shutdown  status  tail  version

stop <name>      停止某一个进程(name)，name为[program:cobar]里配置的值，这个示例就是cobar。 
start <name>     启动某个进程 
restart <name>   重启某个进程 
stop <gname>:*   重启属于名为gname这个分组的进程(start,restart同理) ，如：stop appgroup:wapp
stop all         停止全部进程，注：start、restart、stop都不会载入最新的配置文件。 
reload           载入最新的配置文件，停止原有进程并按新的配置启动、管理所有进程。 
update           根据最新的配置文件，启动新配置或有改动的进程，配置没有改动的进程不会受影响而重启。 注意：显示用stop停止掉的进程，用reload或者update都不会自动重启。

OK，基本的操作就是类似这个了

supervisor还支持以WEB方式监控管理进程
找到[inet_http_server]这一段，修改成

[inet_http_server]         ; inet (TCP) server disabled by default
port=*:9001                ; (ip_address:port specifier, *:port for all iface)
username=admin             ; (default is no username (open server))
password=123               ; (default is no password (open server))

然后保存配置，重启supervisord
# supervisord reload
