nagios安装与配置.doc

linux_nagios服务端：yum install httpdphp1.添加账户和组：useradd nagiosgroupadd nagcmdusermod -G nagcmd nagiosusermod -G nagcmd apache2.安装nagios:tar zxvf nagios-3.2.0.tar.gz -C /usr/local/src/cd /usr/local/src/nagios-3.2.0/./configure -with-nagios-group=nagcmd-prefix=/usr/local/nagios #有的写-with-command-group=nagcmd 我做实验时没这么写make allmake installmake install-initmake install-configmake install-commandmodemake install-webconf3.安装插件nagios-plugins-1.4.14.tartar zxvf nagios-plugins-1.4.14.tarcd /nagios-plugins-1.4.14./configure -with-nagios-user=nagios -with-nagios-group=nagiosmakemake install4.安装httpd，如果安装nagios之前用yum 安装了httpd，则不用改httpd的配置文件。如果在安装nagios之后才用yum安装的httpd 或编译安装的httpd：则在 /etc/httpd/conf/httpd.conf 后面加入以下内容：vim /httpd.conf#setting for nagiosScriptAlias /nagios/cgi-bin /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.users Require valid-user Alias /nagios /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.users Require valid-user :wq/usr/local/apache/bin/apachctl t #检查APACHE的配置文件有无语法错误5.htpasswd -c/usr/local/nagios/etc/htpasswd.users nagiosadmin #给nagios访问网页加用户6.设置邮件联系人yum install sendmail m4 mailxvim /usr/local/nagios/etc/objects/contacts.cfg define contact contact_name nagiosadmin ;
