unix中配置Supervisor的教程
这篇文章给大家分享的是有关unix中配置Supervisor的教程。小编觉得挺实用的,因此分享给大家做个参考。一起跟随小编过来看看吧。
/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
[root@home supervisor]# ll /etc/supervisord.conf -rw-r--r-- 1 root root 9178 Jan 6 14:18 /etc/supervisord.conf

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
