Nagios监控系统安装文档

Centos-6.X-x86-64

Nrpe-2.12版本

Windows客户端:

Windows2008R2

Windows2003R2

需开启Snmp服务

服务器端安装

一,安装前准备:

1,解决perl编译问题:

后面编译的软件有perl程序,这里要提前设置下环境变量。

批量执行命令如下:

echo'export LC_ALL=C'>>/etc/profile

tail-1 /etc/profile

source/etc/profile

echo$LC_ALL

2,关闭防火墙,安装完后启动防火墙。

/etc/init.d/iptablesstop

/etc/init.d/iptablesstart

2.1解决系统时间同步。

echo‘*/5* * * * /usr/sbin/ntpdate time.windows.com’ >>/var/spool/cron/root

[root@nagios~]# crontab -l

*/5* * * * /usr/sbin/ntpdate time.windows.com >/dev/null 2>&1

3,安装nagios所需基础软件包

批量执行命令如下:

yuminstall gcc glibc glibc-common -y

yuminstall gd gd-devel -y

yuminstall httpd php php-gd -y

3.1创建nagios需要的用户及组

批量命令:

/usr/sbin/useradd-m nagios

/usr/sbin/useraddapache

/usr/sbin/groupaddnagcmd

/usr/sbin/usermod-a -G nagcmd nagios

/usr/sbin/usermod-a -G nagcmd apache

id-n -G nagios

id-n -G apache

groupsnagios

groupsapache

3.2下载软件包

mkdir -p/server/soft

http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.16.tar.gz

二,安装nagios

tarzxf nagios-3.2.0.tar.gz

cdnagios-3.2.0

./configure--with-command-group=nagcmd

make all

make install

make install-init

make install-commandmode

make install-config

make install-webconf

提示:如果是编译安装的httpd是,可以执行./configure--with-command-group=nagcmd --with-httpd-conf=/usr/local/apache2/conf/extra 增加一个编译参数即指定编译nagios web配置的生产路径。然后编辑vi/usr/local/apache2/conf/httpd.conf增加 Includeconf/extra/nagios.conf

1,创建nagios web监控界面登入时需要的用户名及密码

htpasswd-c /usr/local/nagios/etc/htpasswd.users admin

输入密码即可

cat/usr/local/nagios/etc/htpasswd.users

提示:如果为单独编译的apache,则操作命令如下

/usr/local/apache2/bin/htpasswd-c /usr/local/nagios/etc/htpasswd.users admin

2,添加接收监控报警的email地址

vi/usr/local/nagios/etc/objects/contacts.cfg +35

email nagios@localhost

改为:

email baochengcai@autohome.com.cn

快速命令:

sed-I 's#nagios@localhost#baochengcai@autohome.com.cn#'/usr/local/nagios/etc/objects/contacts.cfg

3,启动邮件服务。

/etc/init.d/sendmailstart

chkconfigsendmail on

chkconfig--list sendmail

如果sendmail启动比较缓慢,可以修改/etc/hosts

127.0.0.1 nagios localhost.localdomain localhost #增加主机名hostname

4,配置apache服务

启动apache并加入系统开机自启动:

/etc/init.d/httpdstart

chkconfighttpd on

5,安装nagios插件软件包

tarzxf nagios-plugins-1.4.13.tar.gz

cdnagios-plugins-1.4.13

./configure --with-nagios-user=nagios--with-nagios-group=nagios --enable-perl-modules

make

makeinstall

ls /usr/local/nagios/libexec/|wc -l

#编译如遇到make:***[all] Error 2 则configure 加--with-MySQL=/usr/local/mysql解决

chkconfig nagios on

chkconfig--list nagios

6,验证nagios配置文件(检查语法)

简单方法:/etc/init.d/nagioscheckconfig

[root@nagios~]# /etc/init.d/nagios checkconfig

Runningconfiguration check... OK.

/usr/local/nagios/bin/nagios-v /usr/local/nagios/etc/nagios.cfg

TotalWarnings: 0

TotalErrors: 0

Thingslook okay - No serious problems were detected during the pre-flight check

#Total Warnings:警告和Total Errors:错误都为0,表示配置正常。

#Total Errors:如果不为0必须解决,否则nagios无法启动。

#Total Warnings:这个如果不为0可以启动nagios。

启动nagios服务

/etc/init.d/nagios start

检查nagios进程:

ps -ef|grep nagios |grep -v grep

检查selinux是否关闭

setenforce0

sed-i ' s#SELINUX=enforcing#SELINUX=disabled# ' /etc/selinux/config

getenforce

7,安装nrpe软件:

tar zxf nrpe-2.12.tar.gz

cd nrpe-2.12

./configure

make all

make install-plugin

make install-daemon

makeinstall-daemon-config

nagios服务器端安装结束,后续需要调整参数。

**Nagios添加多账户管理

检查当前系统账号:

[root@nagios ~]# cat /usr/local/nagios/etc/htpasswd.users

admin:HMcYqU.5Bh5bk

xiaomin:$apr1$GFzBDndr$Rd6Qvbc58PCUTPXNjhs8E1

chenkaixiong:$apr1$M6RLaWz8$8Ghi27zHStHaSZ9W1DVgs/

添加系统登录账号:

[root@nagios ~]# htpasswd -m/usr/local/nagios/etc/htpasswd.users chengcai

Newpassword:

Re-typenew password:

Addingpassword for user chengcai

[root@nagios etc]# cat /usr/local/nagios/etc/htpasswd.users

xiaomin:$apr1$GFzBDndr$Rd6Qvbc58PCUTPXNjhs8E1

chenkaixiong:$apr1$M6RLaWz8$8Ghi27zHStHaSZ9W1DVgs/

chengcai:$apr1$lXiSe1w4$HxIw6xSwjon5NshKfbbSx0

配置账号权限:

[root@nagios etc]# egrep -v "^#|^$" cgi.cfg

客户端安装:-linux:

1,解决perl编译问题:

后面编译的软件有perl程序,这里要提前设置下环境变量。

批量执行命令如下:

yum-y install perl-devel perl

echo'export LC_ALL=C'>>/etc/profile

tail-1 /etc/profile

source/etc/profile

echo$LC_ALL

2,关闭防火墙,安装完后启动防火墙。

/etc/init.d/iptables stop

/etc/init.d/iptablesstart

2.1解决系统时间同步。

echo‘*/5* * * * /usr/sbin/ntpdate time.windows.com’ >>/var/spool/cron/root

[root@nagios~]# crontab -l

*/5* * * * /usr/sbin/ntpdate time.windows.com >/dev/null 2>&1

3,在nagios客户端安装插件

mkdir-p /server/soft

cd/server/soft

rz-y (oldboy_tracining_nagios_soft.zip)#老男孩提供的软件包。

unzipoldboy_tracining_nagios_soft.zip

3.1安装nagios-plugins-1.4.13.tar.gz

/usr/sbin/useraddnagios -M -s /sbin/nologin

tarzxf nagios-plugins-1.4.13.tar.gz

cdnagios-plugins-1.4.13

./configure --with-nagios-user=nagios--with-nagios-group=nagios --enable-perl-modules

make

makeinstall

ls /usr/local/nagios/libexec/|wc -l

#编译如遇到make:***[all] Error 2 则configure 加--with-mysql=/usr/local/mysql解决

3.2,安装nrpe软件:

tarzxf nrpe-2.12.tar.gz

cd nrpe-2.12

./configure

make all

make install-plugin

make install-daemon

makeinstall-daemon-config

3.3安装其他相关的插件【iostat】

3.4配置开发的几个基本脚本插件

cp /server/soft/nagios/check_memory.pl /usr/local/nagios/libexec/

cp /server/soft/nagios/check_iostat /usr/local/nagios/libexec

chmod 755/usr/local/nagios/libexec/check_memory.pl

chmod 755/usr/local/nagios/libexec/check_iostat

dos2unix/usr/local/nagios/libexec/check_memory.pl

dos2unix/usr/local/nagios/libexec/check_iostat

3.5配置nrpe

cd/usr/local/nagios/etc

vinrpe.cfg +79

加入可以监控本机的nagios server端IP,如下:

allowed_hosts=10.168.0.217

#注:如果机器大于500台做集群或分布式监控时,可以使用多个nagiosserver-,ip要用逗号隔开。

#可用一条命令执行。↓

#perl -pi -e's/allowed_hosts=127.0.0.1/allowed_hosts=10.168.0.245/g'/usr/local/nagios/etc/nrpe.cfg

grep allowed_host/usr/local/nagios/etc/nrpe.cfg

更改nrpe配置文件信息。

cd /usr/local/nagios/etc

vi nrpe.cfg (shift+g切换到结尾)#注释掉或者干脆删除199-203行,同时在下面新添加要监控的内容。

command[check_load]=/usr/local/nagios/libexec/check_load-w 15,10,5 -c 30,25,20

command[check_mem]=/usr/local/nagios/libexec/check_memory.pl-w 10% -c 3%

command[check_disk]=/usr/local/nagios/libexec/check_disk-w 15% -c 7% -p /

command[check_swap]=/usr/local/nagios/libexec/check_swap-w 20% -c 10%

command[check_iostat]=/usr/local/nagios/libexec/check_iostat-w 6 -c 10

#-c为严重报警

启动:nagios client

/usr/local/nagios/bin/nrpe-c /usr/local/nagios/etc/nrpe.cfg -d

echo"/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d">>/etc/rc.local

ps-ef|grep nagios

netstat-lnt|grep 5666

lsof-I :5666

#重启client端nagios nrpe服务的组合命令
