【Supervisor】配置

/etc/supervisord.conf配置

注意
1、去掉[include]配置的註釋，包括[include]本身
[include]
files = /etc/supervisor/.ini
2、[inet_http_server]中的port配置，:port
[inet_http_server]
port=*:9001

[root@home supervisor]# ll /etc/supervisord.conf 
-rw-r--r-- 1 root root 9178 Jan  6 14:18 /etc/supervisord.conf

[root@home supervisor]# cat /etc/supervisord.conf 
; 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 ".

; include files themselves.

監控Tomcat配置（tomcat.ini）

supervisor不支持進程後臺啓動方式，注意command命令以/usr/local/tomcat/bin/catalina.sh run配置可以避免後臺啓動方式，如此配置supervisor不報錯。
注意：進程日誌配置stdout_logfile=/mnt/logs/tomcat-service.log，在重啓過程中如有不正常情況可以從日誌文件中排查解決問題。

[root@home supervisor]# cat /etc/supervisor/tomcat.ini 
[program:tomcat]
command=/usr/local/tomcat/bin/catalina.sh run          ; the program (relative uses PATH, can take args)
user=rd
priority=999                  ; the relative start priority (default 999)
autostart=true                ; start at supervisord start (default: true)
autorestart=true              ; retstart at unexpected quit (default: true)
startretries=10                ; max # of serial start failures (default 3)
stdout_logfile=/mnt/logs/tomcat-service.log        ; stdout log path, NONE for none; default AUTO
stdout_logfile_maxbytes=1MB   ; max # logfile bytes b4 rotation (default 50MB)
stdout_logfile_backups=10     ; # of stdout logfile backups (default 10)
stdout_capture_maxbytes=1MB   ; number of bytes in 'capturemode' (default 0)

監控Grafana配置（grafana.ini）

grafana是以service方式啓動，同樣有後臺方式啓動的問題，需要將/etc/init.d/grafana-server中
action $"Starting $DESC: ..." su -s /bin/sh -c "nohup ${DAEMON} ${DAEMON_OPTS} >> /dev/null 3>&1 &" $GRAFANA_USER 2> /dev/null
修改爲：
action $"Starting $DESC: ..." su -s /bin/sh -c "nohup ${DAEMON} ${DAEMON_OPTS} >> /dev/null 3>&1 " $GRAFANA_USER 2> /dev/null

修改grafana-server的啓動腳本
