# crontab -l
步骤5：安装gcc、lamp、env、etc
yum install gcc glibc glibc-common -y
yum install gd gd-devel -y
yum install httpd php php-gd -y
yum install mysql* -y
步骤6：添加nagios用户和组
/usr/sbin/useradd -m nagios
#/usr/sbin/useradd apache
/usr/sbin/groupadd nagcmd
/usr/sbin/usermod -a -G nagcmd nagios
/usr/sbin/usermod -a -G nagcmd apache
步骤7：下载和安装nagios
编译主程序；
oldboy_training_nagios_soft.zip
unzip oldboy_training_nagios_soft.zip
# tar xzf nagios-3.5.1.tar.gz
# cd nagios
# ./configure --with-command-group=nagcmd
# make all
# make install
# make install-init
# make install-config
# make install-commandmode
# make install-webconf
步骤8：配置web认证(config web auth)
# htpasswd -cb/usr/local/nagios/etc/htpasswd.users oldboy 888888
Adding password for user oldboy
#
步骤9：安装nagios插件
yum -y install perl-devel
tar zxf nagios-p
# useradd oldboy
# id oldboy
uid=501(oldboy) gid=502(oldboy) groups=502(oldboy)
# htpasswd -cb /usr/local/nagios/etc/htpasswd.users oldboy 888888
Adding password for user oldboy
# yum -y install perl-devel
# tar zxf nagios-plugins-1.4.16.tar.gz
# cd nagios-plugins-1.4.16
# ./configure --with-nagios-user=nagios--with-nagios-group=nagios --enable-perl-modules
# make && make install
# cd ../
# ls /usr/local/nagios/libexec/|wc -l

步骤10：安装nrpe
# tar zxvf nrpe-2.12.tar.gz
# cd nrpe-2.12
# ./configure
# make all
# make install-plugin
# make install-daemon
# make install-daemon-config
# cd ../
#
步骤11：启动nagios服务并检查
1) 启动nagios服务
# /etc/init.d/nagios start
