monit是一款功能非常强大的服务器监控软件，如下是我实践部署的经验。
1，下载软件，并安装
wget http://mmonit.com/monit/dist/monit-5.2.5.tar.gz
tar zxvf monit-5.2.5.tar.gz

./configure

make

make install

2，查看Monit的程序路径
which monit
monit

3, 写配置文件
vim /etc/monitrc
参考模板如下，监控了nginx , juggernaut, redis, delayed_job（有些问题）

set daemon  20set logfile /var/log/monit.logset mail-format { from: monit@example.com }set mailserver smtp.gmail.com port 587    username "xxx@gmail.com" password "xxxxxx"    using tlsv1    with timeout 30 secondsset alert xxxx@gmail.comset httpd port 2812 and    allow username:passwordcheck process nginx with pidfile /opt/nginx/logs/nginx.pid    start program = "/opt/nginx/sbin/nginx"    stop program  = "/usr/bin/pkill -f '/opt/nginx/sbin/nginx'"    if failed host paii.cn port 80 protocol http then restart    if 3 restarts within 5 cycles then timeoutcheck host juggernaut with address 127.0.0.1    start program = "/usr/bin/nohup /usr/local/bin/node /root/node_modules/.bin/juggernaut"    stop program  = "/usr/bin/pkill -f 'node /root/node_modules/.bin/juggernaut'"    if failed port 8080 protocol HTTP        request /application.js        with timeout 10 seconds then restartcheck process redis with pidfile /var/run/redis.pid   start program = "/root/redis-2.2.5/src/redis-server /etc/redis.conf"   stop program = "/usr/bin/pkill -f '/root/redis-2.2.5/src/redis-server /etc/redis.conf'"   if failed host 127.0.0.1 port 6379  then restartcheck process leshi-daemon with pidfile /var/run/leshi.pid   start program = "cmd...."   stop program = "/usr/bin/pkill -f 'http://xxxxx:80/api'"   if failed host 127.0.0.1 port 30002 protocol HTTP        request /live.xml        with timeout 10 seconds  then restart#check process delayed_job with pidfile /var/www/web/tmp/pids/delayed_job.pid#   start program = "/usr/bin/env  RAILS_ENV=production /usr/local/bin/ruby  /var/www/web/script/delayed_job start"#   stop program = "/usr/bin/env  RAILS_ENV=production /usr/local/bin/ruby /var/www/web/script/delayed_job  stop"
