Fedora安装Nagios 4.0.1

Nagios 4.0.1版本安装，适用于RHEL/CentOS 5.x/6.x 或者Fedora 17/18/19。我的环境如下：Centos-6.2Nagios 4.0.1Nagios Plugin 1.5Nagios是一个非常棒的免费的开源的监控工具，它提供给你一个很全面的监控环境，始终密切监视你的机器或者网络，不管是在数据中心还是在你自己的一个小实验室。步骤1：安装需要的依赖包需要安装Apache、PHP和一些库像：gcc、glibc、glibc-common、gd、gd-devel、make、net-snmp[root@taoteng ~]# yum install -y httpd php gcc glibc glibc-common gd gd-devel make net-snmp步骤2:创建一个nagios用户和组创建一个新的nagios用户和nagcmd组账户并设置密码。
[root@taoteng ~]# useradd nagios
[root@taoteng ~]# groupadd nagcmd
接下来，添加nagios和Apache用户到nagcmd组。
[root@tecmint]# usermod -G nagcmd nagios
[root@tecmint]# usermod -G nagcmd apache步骤3：下载Nagios-4.0.1和Nagios-plugin-1.5在/root目录下创建一个安装包以及后续需要下载的安装包的目录。[root@taoteng ~]# mkdir /root/nagios[root@taoteng ~]# cd /root/nagios现在来下载最新版本的Nagio-4.0.1和Nagios-plugin-1.5通过wget命令 [root@taoteng nagios]# wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-4.0.1.tar.gz [root@taoteng nagios]# wget https://www.nagios-plugins.org/download/nagios-plugins-1.5.tar.gz步骤4：提取Nagios和nagios-plugins压缩包我们需要通过tar命令来提取下载的压缩包里面的文件： [root@taoteng nagios]# tar -zxvf nagios-4.0.1.tar.gz [root@taoteng nagios]# tar -zxvf nagios-plugins-1.5.tar.gz紧接着nagios文件夹里面将会出现解压之后的文件夹[root@taoteng nagios]# ll总用量 30668drwxrwxr-x 18 root root 4096 2月 20 21:22 nagios-4.0.1-r-xr-xr-x 1 root root 1696847 2月 20 20:58 nagios-4.0.1.tar.gzdrwxr-xr-x 15 nagios nagios 4096 2月 24 00:58 nagios-cn-3.2.3-r-xr-xr-x 1 root root 9638175 2月 20 20:58 nagios-cn-3.2.3.tar.bz2drwxr-xr-x 15 200 300 4096 2月 20 22:04 nagios-plugins-1.5-r-xr-xr-x 1 root root 2428258 2月 20 20:58 nagios-plugins-1.5.tar.gz配置nagios的核心
现在，首先我们将配置nagios核心，将进入到nagios文件夹里面运行configure命令，如果一切运行顺利将会出现下面的界面：[root@taoteng nagios]# cd nagios-4.0.1[root@taoteng nagios-4.0.1]# ./configure --with-command-group=nagcmd
输出示例：Nagios executable: nagios Nagios user/group: nagios,nagios Command user/group: nagios,nagcmd Event Broker: yes Install ${prefix}: /usr/local/nagios Install ${includedir}: /usr/local/nagios/include/nagios Lock file: ${prefix}/var/nagios.lock Check result directory: ${prefix}/var/spool/checkresults Init directory: /etc/rc.d/init.d Apache conf.d directory: /etc/httpd/conf.d Mail program: /bin/mail Host OS: linux-gnu Web Interface Options: ------------------------ HTML URL: http://localhost/nagios/ CGI URL: http://localhost/nagios/cgi-bin/ Traceroute （used by WAP）: /bin/tracerouteReview the options above for accuracy. If they look okay,type "make all" to compile the main program and CGIs.
随后配置和编译所有的的二进制文件，make和make install将会在你的机器上安装所需的二进制文件然后才能继续安装，[root@taoteng nagios-4.0.1]# make[root@taoteng nagios-4.0.1]# make install
输出样例：
*** Main program, CGIs and HTML files installed ***You can continue with installing Nagios as follows （type "make"without any arguments for a list of all possible options）: make install-init - This installs the init script in /etc/rc.d/init.d make install-commandmode - This installs and configures permissions on the directory for holding the external command file make install-config - This installs sample config files in /usr/local/nagios/etc
其实从上面的样例上可以看出下步我们需要的操作步骤，接着执行make install-init去安装初始化脚本。
[root@taoteng nagios-4.0.1]# make install-init从输出的命令行上可以看出我们需要安装外部命令文件（libxce）[root@taoteng nagios-4.0.1]# make install-commandmode接下来安装nagios示例文件，运行下面的命令：[root@taoteng nagios-4.0.1]# make install-config输出示例：
/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc/objects/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/nagios.cfg /usr/local/nagios/etc/nagios.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/cgi.cfg /usr/local/nagios/etc/cgi.cfg/usr/bin/install -c -b -m 660 -o nagios -g nagios sample-config/resource.cfg /usr/local/nagios/etc/resource.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/templates.cfg /usr/local/nagios/etc/objects/templates.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/commands.cfg /usr/local/nagios/etc/objects/commands.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/contacts.cfg /usr/local/nagios/etc/objects/contacts.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/timeperiods.cfg /usr/local/nagios/etc/objects/timeperiods.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/localhost.cfg /usr/local/nagios/etc/objects/localhost.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/windows.cfg /usr/local/nagios/etc/objects/windows.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/printer.cfg /usr/local/nagios/etc/objects/printer.cfg/usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/switch.cfg /usr/local/nagios/etc/objects/switch.cfg*** Config files installed ***Remember, these are *SAMPLE* config files. You"ll need to readthe documentation for more information on how to actually defineservices, hosts, etc. to fit your particular needs.
步骤5：自定义nagios配置文件打开“contacts.cfg”文件编辑当出现报警状态时候的nagios管理员的电子邮箱[root@taoteng nagios-4.0.1]# vi /usr/local/nagios/etc/objects/contacts.cfg输出样例：################################################################################# CONTACTS###############################################################################################################################################################
# Just one contact defined by default - the Nagios admin （that"s you）# This contact definition inherits a lot of default values from the "generic-contact"# template which is defined elsewhere.
define contact{ contact_name nagiosadmin ; Short name of user use generic-contact ; Inherit default values from generic-contact template （defined above） alias Nagios Admin ; Full name of user
email xiantao412@sina.com ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ****** }步骤6：安装和配置Nagios的web接口到目前为止，我们已经完成了所有的配置，接下来将用下面的命令来配置Nagios的web接口。下面的命令将配置web接口并同时创建一个“nagiosadmin”管理用户。[root@taoteng nagios-4.0.1]# make install-webconf接下来的这步将会创建一个密码为“nagiosadmin”记住这个密码，因为待会儿在浏览器中登录的时候将会用到这个密码。
[root@taoteng nagios-4.0.1]# htpasswd -s -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
New password:
Re-type new password:
Adding password for user nagiosadmin
重启Apache服务使新的配置生效。
