7. monit基本設定
• # cat /etc/monit/monitrc| grep -v "^#"
• set daemon 60
• with start delay 240
• set mailserver smtp.gmail.com port 587 username
"example@example.com" password "example" using tlsv1
• set alert example@example.com not { instance }
• set httpd port 2812 and
• use address localhost # only accept connection from localhost
• allow localhost # allow localhost to connect to the server and
• include /etc/monit/conf.d/*.conf
• monitのhttpdを動かさないとステータスが取れない
9. VNC
• # cat /etc/monit/conf.d/vnc4server.conf
• check process vnc4server matching Xvnc4
• start program "/bin/su user -c 'vnc4server :1 -geometry 1200x768'"
• stop program "/bin/su user -c 'vnc4server -kill :1'"
• #if failed port 5901 then alert
• #if failed port 5901 for 5 cycles then restart
• VNCのポートを認証無しでアクセスを繰り返すと通常のVNCアクセスも出
来なくなる。
10. Iceweasel/Firefox
• # cat /etc/monit/conf.d/iceweasel.conf
• check process iceweasel matching firefox-bin
• start program "/bin/su user -c 'DISPLAY=:1.0 /usr/bin/iceweasel & '"
• stop program "/usr/bin/pkill -9 firefox-bin"
• if totalmem > 500.0 MB for 5 cycles then restart
• if cpu > 60% for 5 cycles then alert
• if cpu > 90% for 5 cycles then restart
• depends on vnc4server
• プロセス名でのマッチングはマニュアル記載サンプルの方法では文法エ
ラー
• NG:
• check process matching "/sbin/dynamic_pager -F /private/var/vm/swapfile"
• OK:
CHECK PROCESS <unique name> <PIDFILE <path> | MATCHING <regex>>
