6.启动服务
chkconfig --add nagios
chkconfig nagios on
chown -R nagios.nagios /usr/local/nagios
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
service httpd restart
7.#It appears as though you do not have permission to view information for any of the hosts you requested...
vim /usr/local/nagios/etc/cgi.cfg
use_authentication=0
至此nagios安装完毕
===================================服务端安装插件nagios-plugins==============================
8.安装插件
tar xzvf tar xzf nagios-plugins.tar.gz
cd nagios-plugins-1.4.15
./configure --with-nagios-user=nagios --with-nagios-group=nagios
make
make install
9.编辑填上自己email
vim /usr/local/nagios/etc/objects/contacts.cfg
email nagios@localhost ; **** CHANGE THIS TO YOUR EMAIL
10.启动
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
chown -R nagios.nagios /usr/local/nagios
service nagios restart
11.编辑
vim /usr/local/nagios/etc/nagios.cfg
cfg_dir=/usr/local/nagios/etc/monitor
mkdir -p /usr/local/nagios/etc/monitor
chown nagios.nagios monitor -R
配置 commands.cfg
vim /usr/local/nagios/etc/objects/commands.cfg
在最后一行添加
#check nrpe
define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
/etc/init.d/nagios restart
===================================服务端安装插件nrpe==============================
1.
安装nrpe-2.12
cd nrpe-2.12
./configure --prefix=/usr/local/nagios
安装nrpe 插件
make all
make install-plugin
make install-daemon
make install-daemon-config
make install-xinetd
vim/etc/services最后加入
nrpe 5666/tcp #NRPE随后重启 xinetd 服务
/bin/systemctlrestart xinetd.service
netstat -ant |grep 5666
2.测试插件与客户端是否能正常通信
/usr/local/nagios/libexec/check_nrpe -H 192.168.6.101
NRPE v2.12
三． 测试脚本没有问题
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
cd /usr/local/nagios/var/rw
chmod 777 nagios.cmd
vim /usr/local/nagios/etc/nrpe.cfg
command=/usr/local/nagios/libexec/check_users -w 5 -c 10
command=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
command=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /
command=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z
command=/usr/local/nagios/libexec/check_procs -w 250 -c 300
command=/usr/local/nagios/libexec/check_swap -w 20 -c 10
四． 重启 nagios
/etc/init.d/nagios restart
五． 连接web 测试
http://192.168.6.103/nagios
========================================================================
一．Nagios 监控客户端
1.在客户端安装监控插件
useradd nagios
groupadd nagcmd
useradd -s /usr/sbin/nologin nagios
tar zxvf nagios-plugins-1.4.14.tar.gz
cd nagios-plugins-1.4.14
./configure
make
make install设置插件目录权限
chown nagios.nagios /usr/local/nagios
chown -R nagios.nagios /usr/local/nagios/libexec
2.安装 nrpe daemon
tar zxvf nrpe-2.12.tar.gz
cd nrpe-2.12
./configure --prefix=/usr/local/nagios
./configure
make all
make install-plugin
make install-daemon
make install-daemon-config作为 xinetd 服务nrpe守护进程
make install-xinetd配置 xinetd nrpe 只能由监控服务器监控
vim /etc/xinetd.d/nrpe
only_from = 127.0.0.1 添加nrpe守护进程
vim/etc/services最后加入
nrpe 5666/tcp #NRPE随后重启 xinetd 服务
/bin/systemctlrestart xinetd.service
3.查看服务器是否起来了
netstat -ant |grep 5666
tcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN看到 5666 端口已经开始监听了，说明没问题
测试本地是否可以通信
/usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.12
==============================================================================
重启nrpe
先停止nrpe
# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
# cat /var/run/nrpe.pid
29116
# cat /var/run/nrpe.pid
25316
#kill 25316
后启动
# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
netstat -an | grep 5666
设置自动启动
vi /etc/rc.local在其中加入此行：
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
被监控端设置完成
