Nagios 服务端安装

第一步：修改YUM源码
cd /etc/yum.repos.d/
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

第二步：调整字符集
echo 'export LC_ALL=C'>> /etc/profile
source /etc/profile
echo $LC_ALL
第三部：关闭防火墙
/etc/init.d/iptables stop
/etc/init.d/iptables stop
chkconfig iptables off
setenforce 0         #临时生效
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config  #永久生效
setenforce 0   
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config  

       
第四部：时间同步       
/usr/sbin/ntpdate pool.ntp.org
echo '#time sync'>>/var/spool/cron/root
echo '*/10 * * * * /usr/sbin/ntpdate pool.ntp.org >/dev/null 2>&1'>>/var/spool/cron/root
crontab -l


第五步：安装相关依赖库
yum install gcc glibc glibc-common -y
yum install gd gd-devel -y
yum install httpd php php-gd -y
yum install mysql* -y

第六步：创建NAGIOS用户和组
/usr/sbin/useradd -m nagios
/usr/sbin/groupadd nagcmd
#/usr/sbin/useradd apache   ##如果不是yum安装的需要添加apache用户
/usr/sbin/usermod -a -G nagcmd nagios
/usr/sbin/usermod -a -G nagcmd apache
第七步：安装NAGIOS软件
[ ! -d /home/lvnian/tools  ] &&  mkdir /home/lvnian/tools -p
cd /home/lvnian/tools

tar xzf nagios-3.5.1.tar.gz
cd nagios
./configure --with-command-group=nagcmd
make all
make install
make install-init
make install-config
make install-commandmode
make install-webconf
cd ../

第八步：配置web认证
用于打开web页面时，输入用户和密码登录

htpasswd -cb /usr/local/nagios/etc/htpasswd.users lvnian 123456

把密码文件生成在/usr/local/nagios/etc/htpasswd.users的原因是：
[iyunv@Nagios tools]# cat /etc/httpd/conf.d/nagios.conf |grep AuthUserFile
   AuthUserFile /usr/local/nagios/etc/htpasswd.users
   AuthUserFile /usr/local/nagios/etc/htpasswd.users
[iyunv@Nagios tools]#


第九步：安装ngios插件
cd /home/lvnian/tools
yum -y install perl-devel
tar zxf nagios-plugins-1.4.16.tar.gz
cd nagios-plugins-1.4.16
./configure --with-nagios-user=nagios --with-nagios-group=nagios --enable-perl-modules
make && make install
ls /usr/local/nagios/libexec/|wc -l

cd /home/lvnian/tools
tar zxvf nrpe-2.12.tar.gz
cd nrpe-2.12
./configure
make all
make install-plugin
make install-daemon
make install-daemon-config
cd ..

第十部：启动nagios
/etc/init.d/nagios start
/etc/init.d/httpd start
lsof -i tcp:80
ps -ef|grep nagios


打开http://10.0.0.3/nagios/ 即可进入nagios页面
输入用户名：lvnian

    密码  ： 123456
