redhat 4 nagios搭建演练
系统：redhat 4
软件：nagios-3.0.3.tar.tar，nagios-plugins-1.4.13.tar.gz，httpd为系统自带的
一、创建相关账号和目录
[root@web ~]# groupadd nagios
[root@web ~]# groupadd nagcmd
[root@web ~]# useradd nagios -g nagcmd -d /usr/local/nagios
[root@web ~]# passwd nagios
Changing password for user nagios.
New UNIX password:
BAD PASSWORD: it is too simplistic/systematic
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[root@web ~]# mkdir -p /usr/local/nagios
[root@web ~]# chown -R nagios.nagios /usr/local/nagios/
[root@web ~]# chmod 755 /usr/local/nagios
二、安装nagios
[root@web ~]# tar -zxvf nagios-3.0.3.tar.tar
[root@web nagios-3.0.3]# ./configure --with-command-group=nagcmd
..........
Web Interface Options:
------------------------
HTML URL:
CGI URL:
Traceroute (used by WAP): /bin/traceroute
Review the options above for accuracy. If they look okay,
type 'make all' to compile the main program and CGIs.
[root@web nagios-3.0.3]# make all
........

make install-config
- This installs sample config files in /usr/local/nagios/etc
make[1]: Leaving directory `/root/nagios-3.0.3'
[root@web nagios-3.0.3]# make install-init

*** Config files installed ***
Remember, these are *SAMPLE* config files. You'll need to read
the documentation for more information on how to actually define
services, hosts, etc. to fit your particular needs.
[root@web nagios-3.0.3]# make install-commandmode
/usr/bin/install -c -m 775 -o nagios -g nagcmd -d /usr/local/nagios/var/rw
chmod g+s /usr/local/nagios/var/rw
*** External command directory configured ***
三、配置nagiso
