在RHEL5.3上配置基本的Nagios系统(使用Nagios-3.1.2)
CentOS 5.5+Nginx+Nagios监控端和被控端安装配置指南
Ubuntu 13.10 Server 安装 Nagios Core 网络监控运用
1 开始下载：
wget ?use_mirror=jaist
如下图所示，下载free版本的。
安装前准备工作，安装一些lib包：
[root@cache-2 root]# yum -y install httpd gcc glibc glibc-common
# yum install -y gcc glibc glibc-common gd gd-devel xinetd openssl-devel
2 进行selinux设置，或者关闭selinux
查看SELinux状态：
(1)/usr/sbin/sestatus -v ##如果SELinux status参数为enabled即为开启状态
SELinux status: enabled
(2)getenforce ##也可以用这个命令检查
关闭SELinux：
(3)临时关闭（不用重启机器）：
setenforce 0 ##设置SELinux 成为permissive模式
##setenforce 1 设置SELinux 成为enforcing模式
(4)修改配置文件需要重启机器：
修改/etc/selinux/config 文件
将SELINUX=enforcing改为SELINUX=disabled
重启机器即可
3 开始准备nagios安装环境
(1) 添加nagios运行所需要的用户和组：
groupadd nagcmd
useradd -m nagios
usermod -a -G nagcmd nagios
把apache加入到nagcmd组，以便于在通过web Interface操作nagios时能够具有足够的权限：
# usermod -a -G nagcmd apache
4 编译安装准备
./configure --with-command-group=nagios --prefix=/opt/app/nagios --enable-embedded-perl --with-httpd-conf=/usr/local/apache2/conf
[root@cache-2 nagios-4.0.6]# ./configure --with-command-group=nagios --prefix=/opt/app/nagios --enable-embedded-perl --with-httpd-conf=/usr/local/apache2/conf

checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu

Review the options above for accuracy. If they look okay,
type 'make all' to compile the main program and CGIs.
[root@cache-2 nagios-4.0.6]# ./configure --with-command-group=nagios --prefix=/opt/app/nagios --enable-embedded-perl --with-httpd-conf=/usr/local/apache2/conf checking for a BSD-compatible install... /usr/bin/install -c checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no ............................. HTML URL: CGI URL: Traceroute (used by WAP): /bin/traceroute Review the options above for accuracy. If they look okay, type 'make all' to compile the main program and CGIs.
5 开始make安装
5.1 make all
[root@cache-2 nagios-4.0.6]# make all
cd ./base && make
make[1]: Entering directory `/root/nagios-4.0.6/base'
gcc -Wall -I.. -g -O2 -DHAVE_CONFIG_H -DNSCORE -c -o nagios.o nagios.c
gcc -Wall -I.. -g -O2 -DHAVE_CONFIG_H -DNSCORE -c -o broker.o broker.c
gcc -Wall -I.. -g -O2 -DHAVE_CONFIG_H -DNSCORE -c -o nebmods.o nebmods
