一键安装nagios


此脚本仅仅适用于centos 6.4 x86_64,yum安装的httpd和php,这里的安装过程以后我会整理一份手工安装版本的 需要源码安装的  请期待后面的更新。

nagios的报警之强大目前还没有别的软件可以比肩,也是运维人员必须要掌握的一个软件。包括nagios脚本的开发,各种应用的监控。这里先给新手朋友一个如何安装nagios的思路.

直接上脚本

#!/bin/bash

#install nagios-server or nagios-plugs
read -p "Please input your nagiosadmin's password:" a
selinux=`grep SELINUX=enforcing /etc/selinux/config | awk -F "=" '{print $2}'`
if [ "$selinux" == "enforcing" ]
   then
      echo "your system Selinux not shut down,"
      exit 1
fi
yum install -y wget gcc gcc++ gcc* bc net-snmp net-snmp-utils net-snmp-libs  libpng libpng-devel libjpeg libjpeg-devel openssl098e gd* gd2* openssl-devel* openssl*
cd /usr/local/src
if [ -f nagios-4.0.1.tar.gz ]
then
     echo ".........................................nagios.tar.gz..................is OK!!!"
else
     echo "nagios.tar.gz.............................is not ok!!!..................download"
     wget http://jaist.dl.sourceforge.net/project/nagios/nagios-4.x/nagios-4.0.1/nagios-4.0.1.tar.gz
fi
if [ -f nagios-plugins-1.5.tar.gz ]
then
    echo "............................................nagios-plugs .................is ok!!!"
else
    echo "nagios-plugins-1.5.tar.gz....................is not ok !!!! ..............download"
    wget https://www.nagios-plugins.org/download/nagios-plugins-1.5.tar.gz
fi
if [ -f nrpe-2.15.tar.gz ]
then
   echo "............................................nrpe-2.15.tar.gz.................is ok!!!"
else
   echo "..................................nrpe-2.15.tar.gz...is not ok!!!............download"
   wget http://jaist.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz

###add install nagios ID:
useradd -m nagios
echo "nagios" | passwd --stdin nagios
###add install  gid:
groupadd nagcmd
###daemon 为apache运行账号:
usermod -a -G nagcmd daemon
###install nagios-4.0.1.tar.gz
tar -zxf nagios-4.0.1.tar.gz && cd nagios-4.0.1
./configure --with-command-group=nagcmd --with-gd-lib=/usr/local/libgd/lib/ --with-gd-inc=/usr/local/libgd/include/
make all
make install
make install-init
make install-config
make install-commandmode
cd ../
cat >>/etc/httpd/conf/httpd.conf<<EOF
###nagios's cgi for httpd:
ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
<Directory "/usr/local/nagios/sbin">
#  SSLRequireSSL
   Options ExecCGI
   AllowOverride None
   Order allow,deny
   Allow from all
#  Order deny,allow

   AuthName "Nagios Access"
   AuthType Basic
   AuthUserFile /usr/local/nagios/etc/htpasswd.users
   Require valid-user
</Directory>

##########################################################
###location nagios admin   password(default:che100):
htpasswd -cb /usr/local/nagios/etc/htpasswd.users nagiosadmin $a
###service httpd server:
service httpd restart
###install nagios-plugs(default:/usr/local/nagios/):
tar -xzf nagios-plugins-1.5.tar.gz
cd nagios-plugins-1.5
./configure --with-nagios-user=nagios --with-nagios-group=nagios
make
make install
cd ../
###install nrpe:
tar -zxf nrpe-2.15.tar.gz
cd nrpe-2.15
./configure && make all && make install-plugin
###禁用suexec的功能.此功能对CGI的执行路径进行了限制
setenforce 0
###stop iptables:
service iptables stop
###start nagios  server:
service nagios restart
echo "--------------- nagios server install ok!!!------------------------"
echo "  "
echo "--------------service nagios start is start -----------------------"
echo "  "

安装之后访问:

http://你的服务器的IP/nagios

默认的用户名是:nagiosadmin      密码是脚本开始时候让你输入的密码。

说明:

ps:由于本人的shell 脚本比较烂,有想法的朋友可以指点一下。
