linux中使用munin cgi 动态生成图形文件的方式
|
今天有点时间搞了一下munin cgi了,下面我们来看小编整理的一篇关于linux中使用munin cgi 动态生成图形文件的例子,希望对各位有帮助. 今天又弄了一下munin,发现有些图片出不来. http://Cuoxin.com/static/dynazoom.html?cgiurl_graph=/munin-cgi/munin-cgi-graph&plugin_name=xxxxxx 加载图片的地方报404错误. 1，安装munin 请参考:linux munin 服务器监控 安装配置 2，安装munin-nginx # yum install munin-nginx spawn-fcgi 安装完了以后,在4个地方,会产生重要文件. [root@node1 www]# ll /etc/nginx/conf.d/ |grep munin -rw-r--r-- 1 root root 1427 12月 30 14:11 munin.conf //nginx的配置文件 [root@node1 www]# ll /var/www/cgi-bin/ 总用量 24 -rwxr-xr-x 1 root munin 14530 11月 27 03:37 munin-cgi-graph //perl cgi程序 -rwxr-xr-x 1 root munin 4245 11月 27 03:37 munin-cgi-html [root@node1 www]# ll /etc/init.d/ |grep munin-fcgi -rwxr-xr-x 1 root root 1123 12月 30 19:22 munin-fcgi-graph //调用munin-cgi-graph的系统脚本 -rwxr-xr-x 1 root root 1037 12月 29 15:59 munin-fcgi-html [root@node1 www]# whereis spawn-fcgi //perl程序的承载器 spawn-fcgi:/usr/bin/spawn-fcgi /usr/share/man/man1/spawn-fcgi.1.gz 在这里注意,/etc/init.d/munin-fcgi-graph,这个文件启动munin-cgi-graph,老是有问题,所以从官方网站找到了启动脚本. 3，修改munin.conf的主配置文件 [root@node1 munin]# cat munin.conf |awk '{if($0 !~ /^$/ && $0 !~ /#/) {print $0}}' dbdir /var/lib/munin htmldir /var/www/html/munin logdir /var/log/munin rundir /var/run/munin tmpldir /etc/munin/templates includedir /etc/munin/conf.d graph_strategy cgi //在此处将cron改为cgi cgiurl_graph /munin-cgi/munin-cgi-graph html_strategy cron [munin] address 127.0.0.1 use_node_name yes 4,修改nginx的munin虚拟机 [root@node1 www]# cat /etc/nginx/conf.d/munin.conf |awk '{if($0 !~ /^$/ && $0 !~ /#/) {print $0}}' server { listen 80; server_name munin.51yip.com; //自定义 root /var/www/html/munin; //munin html的根目录 index index.html index.htm; location ^~ /munin-cgi/munin-cgi-graph/ { fastcgi_split_path_info ^(/munin-cgi/munin-cgi-graph)(.*); fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_pass unix:/var/run/munin/spawn-fcgi-munin-graph.sock; include fastcgi_params; } } 5,启动脚本 [root@node1 www]# cat /etc/init.d/spawn-fcgi-munin-graph |awk '{if($0 !~ /^$/ && $0 !~ /#/) {print $0}}' PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin NAME=spawn-fcgi-munin-graph PID_FILE=/var/run/munin/$NAME.pid SOCK_FILE=/var/run/munin/$NAME.sock SOCK_USER=tank //nginx的启动用户 FCGI_USER=munin FCGI_GROUP=munin FCGI_WORKERS=2 DAEMON=/usr/bin/spawn-fcgi DAEMON_OPTS="-s $SOCK_FILE -F $FCGI_WORKERS -U $SOCK_USER -u $FCGI_USER -g $FCGI_GROUP -P $PID_FILE -- /var/www/cgi-bin/munin-cgi-graph" if [ ! -x $DAEMON ]; then echo "File not found or is not executable: $DAEMON!" exit 0 fi status() { if [ ! -r $PID_FILE ]; then return 1 fi for FCGI_PID in `cat $PID_FILE`; do if [ -z "${FCGI_PID}" ]; then return 1 fi FCGI_RUNNING=`ps -p ${FCGI_PID} | grep ${FCGI_PID}` if [ -z "${FCGI_RUNNING}" ]; then return 1 fi done; return 0 } start() { if status; then echo "FCGI is already running!" exit 1 else $DAEMON $DAEMON_OPTS fi } stop () { if ! status; then echo "No PID-file at $PID_FILE found or PID not valid. Maybe not running" exit 1 fi for PID_RUNNING in `cat $PID_FILE`; do kill -9 $PID_RUNNING done rm -f $PID_FILE rm -f $SOCK_FILE } case "$1" in start) echo "Starting $NAME: " start echo "... DONE" ;; stop) echo "Stopping $NAME: " stop echo "... DONE" ;; force-reload|restart) echo "Stopping $NAME: " stop echo "Starting $NAME: " start echo "... DONE" ;; status) if status; then echo "FCGI is RUNNING" else echo "FCGI is NOT RUNNING" fi ;; *) echo "Usage: $0 {start|stop|force-reload|restart|status}" exit 1 ;; esac exit 0 注意:其实上述脚本就是围绕以下命令写的,也可以说上述脚本与以下命令等同. # spawn-fcgi -s /var/run/munin/spawn-fcgi-munin-graph.sock -F 2 -U tank -u munin -g munin /var/www/cgi-bin/munin-cgi-graph 6,权限设置 # chown tank:munin -R /var/www/cgi-bin/ //tank为nginx启动用户 这一步,非常非常重要,这一步不做的话,图片出不来,nginx会报以下错误,因为这个小问题,费了我好几个小时. 2014/12/29 18:20:56 [error] 12263#0: *1 connect() to unix:/var/run/munin/spawn-fcgi-munin-graph.sock failed (111: Connection refused) while connecting to upstream, 7,重启相关服务 # /etc/init.d/nginx restart # /etc/init.d/munin-node restart # chmod +x /etc/init.d/spawn-fcgi-munin-graph # /etc/init.d/spawn-fcgi-munin-graph start 等一会后,久违的图片出来. （编辑：银川站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
