进程监控神器M/Monit+Monit

目的

需要实时监控进程的状态，可以从页面重启进程，集中监控所有主机的进程

安装

1，安装包下载

Mmonit     https://mmonit.com/dist/mmonit-3.5.1-linux-x64.tar.gz

Monit         https://mmonit.com/monit/dist/monit-5.3.1.tar.gz

2，部署Mmonit

1> 安装mysql

传送门 https://blog.espnlol.com/?p=82

2>安装mmonit

tar xvzf mmonit-3.5.1-linux-x64.tar.gz
mv mmonit-3.5.1 /usr/local
ln -s /usr/local/mmonit-3.5.1/ /usr/local/mmonit
mysql –u root –p
password:******
mysql>create database mmonit;
mysql> GRANT ALL ON mmonit.* to mmonit@localhost identified by 'mmonit';
mysql>quit
cd /usr/local/mmonit/db
mysql -u mmonit mmonit -p < mmonit-schema.mysql

3>配置mmonit

vi /usr/local/mmonit/conf/server.xml

<Connector address="*" port="8099" processors="5" />  更改web端口
使用mysql数据库，其他注释掉
<Realm url="mysql://mmonit:mmonit@127.0.0.1:3306/mmonit" 
                  minConnections="1"
                  maxConnections="100"
                  reapConnections="1000" />

4>启动服务

先将系统日期变更为2011年6月6日

date 060610002011

然后启动服务

/usr/local/mmonit/bin/mmonit start

然后将系统时间还原即可

ntpdate  3.centos.pool.ntp.org

写入启动项

echo “/usr/local/mmonit/bin/mmonit start”>>/etc/rc.d/rc.local

3,部署monit

1>安装monit

tar xf monit-5.3.1.tar.gz 
cd monit-5.3.1
./configure --prefix=/usr/local/monit --with-openssl=/usr/local/ssl --enable-threads
make
make install
cd /usr/local/monit
mkdir etc
cd etc
mkdir monit.d
vi monitrc
set daemon  60              # check services at 1-minute intervals
set logfile syslog facility log_daemon
set idfile /var/.monit.id
set statefile /var/.monit.state
 set eventqueue
     basedir /var/monit  # set the base directory where events will be stored
     slots 100           # optionally limit the queue size
 set mmonit http://monit:monit@127.0.0.1:8099/collector
set httpd port 2812 and
    use address 0.0.0.0  # only accept connection from localhost
    allow 127.0.0.1       # allow localhost to connect to the server and
    allow admin:monit      # require user 'admin' with password 'monit'
  check system sysload
    if loadavg (1min) > 20 then alert
    if loadavg (5min) > 30 then alert
    if memory usage > 75% then alert
    if swap usage > 25% then alert
    if memory usage > 75% then alert
    if swap usage > 25% then alert
    if cpu usage (user) > 70% then alert
    if cpu usage (system) > 30% then alert
    if cpu usage (wait) > 20% then alert
    group server
check filesystem root_space with path /dev/vda1
    if space usage > 80% for 5 times within 15 cycles then alert
check filesystem data_space with path /dev/vdb
    if space usage > 80% for 5 times within 15 cycles then alert
group server
  include /usr/local/monit/etc/monit.d/*

2>配置

更改monitrc权限为600

chmod 600 /usr/local/monit/etc/monitrc

在/usr/local/monit/etc/monit.d下创建相应服务监控配置文件

例：nginx监控文件为nginx

echo "/usr/local/monit/bin/monit -c /usr/local/monit/etc/monitrc" >>/etc/rc.d/rc.local

/usr/local/monit/bin/monit -c /usr/local/monit/etc/monitrc

4,验证与监控

1）查看mmonit web页面

http://ip：8099

默认用户admin 默认密码swordfish（自行更改）

查看各monit监控主机状态正常

5,过期重启

登陆到M/Monit – Admin-General

将时间修改到过期前，重启之后，在恢复时间即可
