nagios服务端安装

1.1.1解决perl编译问题：

echo “export LC_ALL=C” >> /etc/profile

source /etc/profile

echo $LC_ALL

1.1.2解决系统时间同步

echo  "*/10 * * * * /usr/sbin/ntpdate pool.ntp.org >/dev/null 2>&1" >> /var/spool/cron/root

1.1.3安装基础包：

yum install gcc glibc-common -y 

yum install gd gd-devel -y

yum install httpd php* -y

1.3创建需要的用户及组

useradd -m nagios    useradd apache

uermod -s /sbin/nologin  nagios

groupadd nacmd

usermod -a -G nagcmd nagios 

usermod -a -G nagcmd apache

编译安装naigos

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

make all；make install；make install-init；make install-config ；make install-commandmode

make install-webconf ；

编译安装的apache --with-httpd-conf=/usr/local/apache2/conf/extra要指定nagios的conf

创建nagios界面用户htpasswd -c /usr/local/nagios/etc/htpasswd.users user1根据nagios配置选择

修改监控报警email，sed -i ‘s#nagios@localhost#your@email .com /usr/local/nagios/etc/objects/contacts.cfg'

service sendemail start

安装插件软件包：

tar zxf nagios-plugins-1.4.13.tar.gz

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

   make如果出现错误error 2，需要加上--with-mysql=/usr/local/mysql

加入到开启启动 chkconfig --add nagios

验证配置文件：nagios -v /usr/local/nagios/etc/nagios.cfg

selinux需要把-t设为http的上下文

安装nrpe：make install-plugin；make install-daemon；makeinstalll-daemon-config服务端要安装，不然会缺少插件
