1 准备工作
准备3台服务器或VM虚拟机
1.1 准备3台服务器或VM虚拟机
nagios服务器及客户端服务器
| 管理IP地址 | 角色 | 备注 |
| 192.168.1.19 | Nagios监控服务器 |
|
| 192.168.1.18 | Lamp服务器 | 被监控的客户端服务器 |
| 192.168.1.17 | Lnmp服务器 | 被监控的客户端服务器 |
2 开始安装
步骤1：配置yum
[root@nagios ~]# cd /etc/yum.repos.d/
[root@nagiosyum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
步骤2：配置profile
[root@nagios yum.repos.d]# echo 'exportLC_ALL=C'>> /etc/profile
[root@nagios yum.repos.d]# source /etc/profile
[root@nagios yum.repos.d]#
步骤3：关闭防火墙
[root@nagios yum.repos.d]#
[root@nagiosyum.repos.d]# /etc/init.d/iptables stop
[root@nagiosyum.repos.d]# chkconfig iptables off
[root@nagios yum.repos.d]#
[root@nagios yum.repos.d]#
[root@nagiosyum.repos.d]# setenforce 0
[root@nagiosyum.repos.d]# vi /etc/selinux/config
# This file controls the state of SELinux on thesystem.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled- No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
"/etc/selinux/config" 13L, 457C written
[root@nagios yum.repos.d]#
步骤4：配置时间同步 config time sync
[root@nagios ~]#
[root@nagios~]# /usr/sbin/ntpdate pool.ntp.org
[root@nagios~]# echo '#time sync by oldboy at 2015-07-01'>>/var/spool/cron/root
[root@nagios~]# echo '*/10 * * * * /usr/sbin/ntpdate pool.ntp.org >/dev/null2>&1'>>/var/spool/cron/root
[root@nagios~]# crontab -l
步骤5：安装gcc、lamp、env、etc
yum install gcc glibc glibc-common -y
yum install gd gd-devel -y
yum install httpd php php-gd -y
yum install mysql* -y
步骤6：添加nagios用户和组
/usr/sbin/useradd -m nagios
#/usr/sbin/useradd apache
/usr/sbin/groupadd nagcmd
/usr/sbin/usermod -a -G nagcmd nagios
/usr/sbin/usermod -a -G nagcmd apache
步骤7：下载和安装nagios
编译主程序；
oldboy_training_nagios_soft.zip
unzip oldboy_training_nagios_soft.zip
[root@nagiostools]# tar xzf nagios-3.5.1.tar.gz
[root@nagiostools]# cd nagios
[root@nagiosnagios]# ./configure --with-command-group=nagcmd
[root@nagiosnagios]# make all
[root@nagiosnagios]# make install
[root@nagiosnagios]# make install-init
[root@nagiosnagios]# make install-config
[root@nagiosnagios]# make install-commandmode
[root@nagiosnagios]# make install-webconf
步骤8：配置web认证(config web auth)
[root@nagios nagios]# htpasswd -cb/usr/local/nagios/etc/htpasswd.users oldboy 888888
Adding password for user oldboy
[root@nagios nagios]#
步骤9：安装nagios插件
yum -y install perl-devel
tar zxf nagios-p
[root@nagiosnagios]# useradd oldboy
[root@nagiosnagios]# id oldboy
uid=501(oldboy) gid=502(oldboy) groups=502(oldboy)
[root@nagiosnagios]# htpasswd -cb /usr/local/nagios/etc/htpasswd.users oldboy 888888
Adding password for user oldboy
[root@nagiosnagios]# yum -y install perl-devel
[root@nagiostools]# tar zxf nagios-plugins-1.4.16.tar.gz
[root@nagiostools]# cd nagios-plugins-1.4.16
[root@nagiosnagios-plugins-1.4.16]# ./configure --with-nagios-user=nagios--with-nagios-group=nagios --enable-perl-modules
[root@nagiosnagios-plugins-1.4.16]# make && make install
[root@nagiosnagios-plugins-1.4.16]# cd ../
[root@nagiostools]# ls /usr/local/nagios/libexec/|wc -l
61
步骤10：安装nrpe
[root@nagiostools]# tar zxvf nrpe-2.12.tar.gz
[root@nagiostools]# cd nrpe-2.12
[root@nagiosnrpe-2.12]# ./configure
[root@nagiosnrpe-2.12]# make all
[root@nagiosnrpe-2.12]# make install-plugin
[root@nagiosnrpe-2.12]# make install-daemon
[root@nagiosnrpe-2.12]# make install-daemon-config
[root@nagiosnrpe-2.12]# cd ../
[root@nagios tools]#
步骤11：启动nagios服务并检查
1) 启动nagios服务
[root@nagiostools]# /etc/init.d/nagios start
[root@nagiostools]# /etc/init.d/httpd start
[root@nagiostools]# lsof -i tcp:80
[root@nagiostools]# ps -ef|grep nagios
[root@nagiostools]# echo "NAGIOS is successfully installed."
[root@nagiostools]# echo ok
2) 进入nagios服务端
