一.安装依赖包
[root@Nagios ~]# yum install -y httpd php [root@Nagios ~]# yum install -y gcc glibc glibc-common [root@Nagios ~]# yum install -y gd gd-devel [root@Nagios ~]# yum install -y perl ntp unzip [root@Nagios ~]# yum install -y openssl-devel [root@Nagios ~]# /etc/init.d/ntpd start [root@Nagios ~]# chkconfig ntpd on [root@Nagios ~]# /usr/sbin/useradd -m nagios [root@Nagios ~]# passwd nagios [root@Nagios ~]# /usr/sbin/groupadd nagcmd [root@Nagios ~]# /usr/sbin/usermod -a -G nagcmd nagios [root@Nagios ~]# /usr/sbin/usermod -a -G nagcmd apache [root@Nagios ~]# id nagios uid=500(nagios) gid=500(nagios) groups=500(nagios),501(nagcmd) [root@Nagios ~]# id apache uid=48(apache) gid=48(apache) groups=48(apache),501(nagcmd)
二.nagios的安装
[root@Nagios ~]# cd /usr/local/src [root@Nagios src]# wget http://nagios-plugins.org/download/nagios-plugins-2.1.1.tar.gz [root@Nagios src]# wget https://assets.nagios.com/downloads/nagioscore/releases/nagios-4.1.1.tar.gz [root@Nagios src]# tar zxvf nagios-4.1.1.tar.gz [root@Nagios src]# cd nagios-4.1.1 [root@Nagios nagios-4.1.1]# ./configure --prefix=/usr/local/nagios --with-comand-group=nagcmd [root@Nagios nagios-4.1.1]# make all [root@Nagios nagios-4.1.1]# make install [root@Nagios nagios-4.1.1]# make install-init [root@Nagios nagios-4.1.1]# make install-config [root@Nagios nagios-4.1.1]# make install-commandmode [root@Nagios nagios-4.1.1]# make install-webconf [root@Nagios nagios-4.1.1]# cp -rf contrib/eventhandlers /usr/local/nagios/libexec/ [root@Nagios nagios-4.1.1]# chown -R nagios:nagios /usr/local/nagios/libexec/eventhandlers
三.nagios plugins的安装
[root@Nagios src]# tar xzf nagios-plugins-2.1.1.tar.gz [root@Nagios src]# cd nagios-plugins-2.1.1 [root@Nagios nagios-plugins-2.1.1]# ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios [root@Nagios nagios-plugins-2.1.1]# make && make install
四.nrpe插件安装
[root@Nagios src]# wget http://nchc.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz [root@Nagios src]# tar zxf nrpe-2.15.tar.gz [root@Nagios src]# cd nrpe-2.15 [root@Nagios nrpe-2.15]# ./configure --prefix=/usr/local/nagios [root@Nagios nrpe-2.15]# make all [root@Nagios nrpe-2.15]# make install-plugin [root@Nagios nrpe-2.15]# make install-daemon [root@Nagios nrpe-2.15]# make install-daemon-config # 测试启动 # /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d # 自带了启动脚本 [root@Nagios nrpe-2.15]# cp -rf init-script.in /etc/init.d/nrpe [root@Nagios nrpe-2.15]# chmod a+x /etc/init.d/nrpe [root@Nagios ~]# /etc/init.d/nrpe start
注:其实nagios获取信息都是靠/usr/local/nagios/libexec/check_nrpe 这个脚本主动获取nrpe服务端信息
五.配置并启动服务
[root@Nagios ~]# vi /usr/local/nagios/etc/objects/contacts.cfg define contact{ contact_name nagiosadmin use generic-contact alias Nagios Admin email ca0gu0@126.com } [root@Nagios ~]# vi /usr/local/nagios/etc/objects/commands.cfg define command{ command_name check_nrpe command_line $USER1$/check_nrpe -H "$HOSTADDRESS$" -c "$ARG1$" } [root@Nagios ~]# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin # 检查配置文件是否正确 [root@Nagios ~]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg [root@Nagios ~]# chkconfig nagios on [root@Nagios ~]# service nagios start [root@Nagios ~]# chkconfig nrpe on [root@Nagios ~]# /etc/init.d/nrpe start [root@Nagios ~]# chkconfig httpd on [root@Nagios ~]# service httpd start [root@Nagios ~]# touch /var/www/html/index.html
六.配置邮件发送
[root@Nagios ~]# yum -y install mailx [root@Nagios ~]# echo "mail test" | mail -s test ca0gu0@126.com #如果不配置mail.rc默认会用本地postfix发送邮件 #email send tools #nano /etc/mail.rc #set from=s0lence@126.com smtp=smtp.126.com #set smtp-auth-user=xx@oo smtp-auth-password=xxoo #set smtp-auth=login
结束!!!!!
