編譯安裝nagios
mkdir /usr/local/nagios
cd nagios-4.2.1
./configure --prefix=/usr/local/nagios
make all && make install && echo $?
make install-config??#?把配置文件樣例復制到nagios的安裝目錄
make install-commandmode #?給外部命令訪問nagios配置文件的權限
make install-init??#?把nagios做成一個運行腳本，使nagios隨系統開機啟動
編譯安裝nagios-plugins
cd /opt/nagios-plugins-2.1.2
./configure --prefix=/usr/local/nagios
make && make install && echo $?
編譯安裝nrpe
cd /opt/nrpe-3.2.1
./configure --prefix=/usr/local/nagios --enable-command-args
編譯

修改nrpe設置
#先備份
cp /usr/local/nagios/etc/nrpe.cfg{,.bak}
#將hda1改為sda
command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/sda
#啟動nrpe
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
修改httpd設置
#先備份
cp /etc/httpd/conf/httpd.conf{,.bak}
vim /etc/httpd/conf/httpd.conf
#在文件最後添加
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>#啟動httpd
systemctl restart httpd
修改nagios配置
設置用戶密碼
！！！！註意，不適用nagiosadmin用戶會報錯，解決方法在"報錯"欄中
htpasswd -c /usr/local/nagios/etc/htpasswd admin
設置郵箱
#安裝發送郵件服務（sendmail不是必須）
yum install -y sendmail mailx
#設置smtp
vim /etc/mail.rc
set from=發送者信息
set smtp=smtp.263.net #smtp，這裏是263郵箱的
set smtp-auth-user=發送者郵箱
set smtp-auth-password=發送者郵箱認證
set smtp-auth=login#測試發送郵件
echo "testmail"|mail -s "title" 接收者郵箱
#修改郵箱配置文件
vim /usr/local/nagios/etc/objects/commands.cfg（郵件發送，mailx可以不設置）
#指定接收者郵箱，多個用" "分隔
vim /usr/local/nagios/etc/objects/contacts.cfg
email 14******[email protected] 15******[email protected] ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ******#添加監控主機配置文件目錄
vim /usr/local/nagios/etc/nagios.cfg
#cfg_file=/usr/local/nagios/etc/objects/localhost.cfg
cfg_dir=/usr/local/nagios/etc/servers/#創建目錄
mkdir -pv /usr/local/nagios/etc/servers/
#添加對nrpe的支持
vim /usr/local/nagios/etc/objects/commands.cfg
#nrpe
define command{
command_name check_nrpe
command_line /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}啟動nagios
systemctl restart nagios
#重新導入配置文件
systemctl reload nagios
報錯
It appears as though you do not have permission to view information for any of the hosts you requested...這是由於web使用用戶不是nagiosadmin，需要修改cgi.cfg
vim /usr/local/nagios/etc/cgi.cfg在nagiosadmin後添加自定義的管理員名稱，如
nagiosadmin,admin
