Nagios服务器架设之一

　　Nagios服务器架设之一
实验环境：RHEL 5.4
一、Nagios服务器安装过程
1）配置服务器端IP地址
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:0c:29:fe:39:A1
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.6.199
GATEWAY=192.168.6.1
TYPE=Ethernet

2）安装Nagios
A，安装前准备
1）创建nagios程序用户、组
[root@localhost ~]# useradd -s /sbin/nologin nagios        ---阻止用户登录服务器
-s :用户登录shell
[root@localhost ~]# mkdir /usr/local/nagios
[root@localhost ~]# chown -R nagios.nagios /usr/local/nagios/      ---修改它的属主属组权限

2)保证系统中sendmail服务器要开启
[root@localhost ~]# service sendmail status
sendmail (pid 3090) 正在运行...

B、编译安装Nagios
[root@localhost ~]# cd /aaa/
[root@localhost aaa]# tar zxf nagios-3.2.0.tar.gz
[root@localhost aaa]# cd nagios-3.2.0
[root@localhost nagios-3.2.0]# ./configure --prefix=/usr/local/nagios/
[root@localhost nagios-3.2.0]# make all ; make install ; make install-init ; make install-commandmode ; make install-config
[root@localhost nagios-3.2.0]# chkconfig --add nagios
[root@localhost nagios-3.2.0]# chkconfig nagios on
[root@localhost nagios-3.2.0]# chkconfig --list nagios       ---查看nagios服务是否运行
nagios             0:关闭      1:关闭      2:启用      3:启用      4:启用      5:启用      6:关闭

C、安装Nagios插件
你可以从http://www.nagios.org官方网站上下载最新的nagios插件
[root@localhost aaa]# tar zxf nagios-plugins-1.4.14.tar.gz
[root@localhost aaa]# cd nagios-plugins-1.4.14
[root@localhost nagios-plugins-1.4.14]# ./configure --prefix=/usr/local/nagios/ ; make ; make install
D、安装Nagios的汉化包
[root@localhost aaa]# tar jxf nagios-cn-3.2.0.tar.bz2
[root@localhost aaa]# cd nagios-cn-3.2.0
[root@localhost nagios-cn-3.2.0]# ./configure ; make all ; make install
E、安装LAMP架构
[root@localhost ~]# mount /dev/cdrom /media/
[root@localhost ~]# vi /etc/yum.repos.d/rhel-debuginfo.repo
[rhel-debuginfo]
name=Red Hat Enterprise Linux $releasever - $basearch - Debugbaseurl=file:///media/Server
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[root@localhost ~]# yum -y install php* mysql* http*
[root@localhost ~]# service httpd start
启动 httpd：                                               [确定]
[root@localhost ~]# chkconfig httpd on
[root@localhost ~]# vi /etc/httpd/conf/httpd.conf
    231 User apache
232 Group apache
391 DirectoryIndex index.php index.html index.html.var
992 #setting for nagios
    993 ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
    994
    995 AuthType Basic
    996 Options ExecCGI
    997 AllowOverride None
    998 Order allow,deny
    999 Allow from all
   1000 AuthName "nagios access"
   1001 AuthUserFile /usr/local/nagios/etc/htpasswd
   1002 Require valid-user
   1003
   1004 Alias /nagios "/usr/local/nagios/share"
   1005
   1006 AuthType Basic
   1007 Options ExecCGI
   1008 AllowOverride None
   1009 Order allow,deny
   1010 Allow from all
   1011 AuthName "nagios access"
   1012 AuthUserFile /usr/local/nagios/etc/htpasswd
   1013 Require valid-user
   1014

创建apache目录的验证文件“/usr/local/nagios/etc/htpasswd”
[root@localhost ~]# htpasswd -c /usr/local/nagios/etc/htpasswd benet
New password:
Re-type new password:
Adding password for user benet

重启apache服务器并进行验证nagios登陆情况
[root@localhost ~]# service httpd restart
停止 httpd：                                               [确定]
启动 httpd：                                               [确定]

至此nagios服务器安装结束
