环境centos5(32bit)，monit-5.17.1，下载地址 /tildeslash/monit/downloads/
1、tar zxvf monit-5.17.1-linux-x86.tar.gz
2、cp monit-5.17.1/conf/monitrc /etc/
3、chmod 0700 /etc/monitrc
4、vi/etc/monitrc
set daemon 30 ##设置30秒检查一次
set logfile /var/log/messages ##设置日志文件
set httpd port 2812 and
use address X.X.X.X
allow 0.0.0.0/0.0.0.0
allow admin:123456
设置访问及monit监听端口，允许登录ip，页面登录用户名密码
check system 127.0.0.1
if loadavg (1min) > 4 then alert
if loadavg (5min) > 2 then alert
if cpu usage > 90% for 10 cycles then alert
if memory usage > 50% then alert
if swap usage > 25% then alert
设置监控本地CPU内存等信息
check process xinetd with pidfile /var/run/xinetd.pid
start program = "/etc/init.d/xinetd start"
stop program = "/etc/init.d/xinetd stop"
if changed pid then alert
根据PID监控进程，服务死掉后自动重启
check process mysql matching "/usr/bin/mysql"
start program = "/etc/init.d/mysql start"
stop program = "/etc/init.d/mysql stop"
check process h5 with MATCHING h5
start program = "/usr/local/bin/h5 > /var/log/h5.log &" with timeout 10 seconds
stop program = "/bin/ps -ef |grep h5|grep -v "grep" |awk '{print $2}'|xargs kill -9" with timeout 10 seconds
if failed port 8081 for 3 cycles then restart
监听进程的另一种方式
还有监听文件等等，就不写了。
主要关注的告警功能
set mailserver port 25 ##设置邮件服务器及端口，这里使用的163邮件服务器
username 发件人有限 password “发件人邮箱密码”
set mail-format {

Date: $DATE
Action: $ACTION
Host: $HOST
Description: $DESCRIPTION

}
#设置邮件发送内容
set alert XXXX@ #设置收件人邮箱，多个收件人写多行
配置好后执行monit程序启动monit-5.17.1/bin/monit
