一，安装apache和php
# yum -y install httpd httpd-devel php php-common php-pdo php-gd 1）编辑apache配置文件 vim /etc/httpd/conf/httpd.conf 391 DirectoryIndex index.html index.php 392 AddType application/x-httpd-php .php 2）写php测试页面 # cat /var/www/html/index.php <?php phpinfo(); ?> 二、安装nagios 1）建立nagios用户 useradd -s /sbin/nologin nagios mkdir /usr/local/nagios chown -R nagios.nagios /usr/local/nagios 2)编译安装nagios tar -zxvf nagios-3.2.3.tar.gz cd nagios-3.2.3 ./configure --prefix=/usr/local/nagios/ make all make install make install-init make install-commandmode make install-config chkconfig --add nagios chkconfig nagios on chkconfig --list nagios 3)安装nagios-plugins tar -zxvf nagios-plugins-1.4.13.tar.gz cd nagios-plugins-1.4.13 ./configure --prefix=/usr/local/nagios/ make && make install 4)安装汉化包 tar -jxvf nagios-cn-3.2.3.tar.bz2 cd nagios-cn-3.2.3 ./configure && make all && make install 三，配置 1）配置httpd添加授权 vim /etc/httpd/conf/httpd.conf 最后加入 ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin" <Directory "/usr/local/nagios/sbin"> AuthType Basic Options ExecCGI AllowOverride None Order allow,deny Allow from all AuthName "Nagios Access" AuthUserFile /usr/local/nagios/etc/htpasswd Require valid-user </Directory> Alias /nagios "/usr/local/nagios/share" <Directory "/usr/local/nagios/share"> AuthType Basic Options None AllowOverride None Order allow,deny Allow from all AuthName "Nagios Access" AuthUserFile /usr/local/nagios/etc/htpasswd Require valid-user </Directory> 2）生成密码 # htpasswd -c /usr/local/nagios/etc/htpasswd nagiosadmin New password: （输入密码） Re-type new password: （再输入一次密码） Adding password for user nagiosadmin #这里为方便就用了nagiosadmin这个用户，如果用其他用户访问时要在/usr/local/nagios/etc/cgi.cfg里将nagiosadmin后面加上相应的用户即可 # service nagios start 启动 3）配置nagios # vim /usr/local/nagios/etc/objects/hosts.cfg /添加要监控的主机，默认这个文件没有的。 define host{ use linux-server host_name peace-nagios alias nagios address 192.168.10.246 } define host{ use linux-server host_name client-173 alias peace-client address 192.168.10.173 } define host{ use linux-server host_name client-206 alias client address 192.168.10.206 } # vim /usr/local/nagios/etc/objects/services.cfg /定义监控主机的服务，默认也是没有的 ############################ peace-nagios ############################## define service { use local-service host_name peace-nagios service_description PING check_command check_ping!100.0,20%!500.0,60% } define service { use local-service host_name peace-nagios service_description SSH check_command check_tcp!12321 } define service { use local-service host_name peace-nagios service_description http check_command check_http } ############################ client-173 ############################## define service { use local-service host_name client-173 service_description PING check_command check_ping!100.0,20%!500.0,60% } define service { use local-service host_name client-173 service_description SSH check_command check_ssh } define service { use local-service host_name client-173 service_description http check_command check_http } ############################ client-206 ############################## define service { use local-service host_name client-206 service_description PING check_command check_ping!100.0,20%!500.0,60% } define service { use local-service host_name client-206 service_description SSH check_command check_ssh } define service { use local-service host_name client-206 service_description http check_command check_http } # chown nagios.nagios hosts.cfg services.cfg /添加用户组 # vim /usr/local/nagios/etc/nagios.cfg /添加刚定义的两个文件 cfg_file=/usr/local/nagios//etc/objects/hosts.cfg cfg_file=/usr/local/nagios//etc/objects/services.cfg 自带的检测一下 # /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg Nagios Core 3.2.3 Copyright (c) 2009-2010 Nagios Core Development Team and Community Contributors Copyright (c) 1999-2009 Ethan Galstad Last Modified: 10-03-2010 License: GPL Website: http://www.nagios.org Reading configuration data...
