#配置文件说明, this English note has a description.

[unix_http_server]file=/tmp/supervisor.sock    ;  Specifies the location of the socket file, which is required when there is no such file; chmod=0700                   ;   Start supervisord  and execute supervisorctl;chown=nobody:nogroup         ; ;username=user                ; ;p assword=123                 ; [inet_http_server]           ;  Open the Web management function, the default is closed, should also be closed port=192.168.182.131:9001    ;  should also be closed, otherwise unsafe, here we to demonstrate username= user                ;  Turn on this feature first password=123                  ; [supervisord]                ;  This is mainly to define some parameters of the Supervisord server side, you must set the location of the Logfile=/tmp/supervisord.log ; supervisord log file, If the log is not set at the current location logfile_maxbytes=50mb        ;  A new log file is generated when logs exceed 50M. When restricted to 0                              ;  does not limit the size of the file logfile_backups=10            ;  the number of log files kept, Supervisor automatically creates 10 when you start the program                               ; backup file for Logrotate, when set to 0, indicates no limit                          &nbNumber of sp;    ;  files loglevel=info                 ;  log level, default info, non-mandatory set pidfile=/tmp/supervisord.pid ;   nodaemon=false                ; minfds=1024                   ;  This is the least system free file descriptor, below this value Supervisord will not                                ;  will start. /proc/sys/fs/file-max view, default 1024, non-must set minprocs=200                  ;  minimum available process descriptor, below this value supervisor will not start.                               ; ulimit -u  can be viewed, without modification by default [program:elasticsearch]       ;  Add Elasticsearch service   command = /home/tomcat/ elasticsearch/bin/elasticsearch ; the initiator path can be autostart = truestartsecs = 5autorestart with parameters  = truestartretries = 3               ;  the other is not written, the configuration file is also explained in English user = tomcat                  ;  which user to start redirect_stderr =  truestdout_logfile_maxbytes = 20mbstdout_logfile_backups = 20stdout_logfile = / home/tomcat/logs/elasticsearch_super.log[program:logstash]directory = /home/tomcat/logstash/bin/ command = /home/tomcat/logstash/bin/logstash -f /home/tomcat/testlog.confautostart =  truestartsecs = 5autorestarT = truestartretries = 3user = tomcatredirect_stderr = truestdout_ logfile_maxbytes = 20mbstdout_logfile_backups = 20stdout_logfile = /home/tomcat/ Logs/logstash_super.log[program:kibana]directory = /home/tomcat/kibana/bin/command = /home /tomcat/kibana/bin/kibanaautostart = truestartsecs = 5autorestart =  truestartretries = 3user = tomcat     redirect_stderr =  truestdout_logfile_maxbytes = 20mbstdout_logfile_backups = 20stdout_logfile =  /home/tomcat/logs/kibana_super.log[group:elk]                                ;  Group Management is very convenient, we can start|stop|statusprograms=elasticsearch,logstash,kibana    ; elk:*  to start or close all services for this group, it must not be turned on. [Include]                                 ;  when we have to manage a lot of processes , written in a file, files = /etc/supervisor/*.conf            ;  a bit too big. The configuration file can be written to multiple files at this time                                            ;  then include.

#supervisord有两种执行命令的方式, you can direct the command line:

[email protected] ~]$ sudo supervisorctl statuselk:elasticsearch RUNNING pid 1430, uptime 0:48:51elk:kib Ana RUNNING pid 1432, uptime 0:48:51elk:logstash RUNNING PID 1431, uptime 0: 48:51

#也可以进入子shell (Ctrl + C exit child shell):

[[email protected] ~]$ sudo supervisorctlelk:elasticsearch                 running   pid 1430,  uptime 0:51:57elk:kibana                        running   pid 1432,  uptime 0:51:57elk:logstash                      running   pid 1431, uptime  0:51:57supervisor> stop elk:*elk:kibana: stoppedelk:elasticsearch: stoppedelk: logstash: stoppedsupervisor> statuselk:elasticsearch                 STOPPED   Nov 30 10:29  Amelk:kibana                        stopped   nov 30 10:29 amelk:logstash                      STOPPED    Nov 30 10:29 am

#最后看看web界面吧 (not feeling safe or cautious)
