【Supervisor】配置

/etc/supervisord.conf配置

注意
1、去掉[include]配置的注释，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

监控Tomcat配置（tomcat.ini）

supervisor不支持进程后台启动方式，注意command命令以/usr/local/tomcat/bin/catalina.sh run配置可以避免后台启动方式，如此配置supervisor不报错。
注意：进程日志配置stdout_logfile=/mnt/logs/tomcat-service.log，在重启过程中如有不正常情况可以从日志文件中排查解决问题。

[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=rdpriority=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 AUTOstdout_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)

监控Grafana配置（grafana.ini）

grafana是以service方式启动，同样有后台方式启动的问题，需要将/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
修改为：
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的启动脚本
