一起搭建linux监控平台之nagios（三）被监控端的环境部署

 这次被监控主要有2种：

1.web服务器

2.mysql服务器

所以得先保证nginx/apache 或者mysql服务的启动；

下面是mysql监控端部署的函数installmysql () 脚本如下

 

installmysql () {
 yum install xinetd -y
 service xinetd start
 cd $path
 useradd -s /sbin/nologin nagios
 tar -zxvf nagios-plugins-1.4.14.tar.gz
 cd nagios-plugins-1.4.14
 ./configure --prefix=$nagiospath --with-nagios-user=nagios --with-nagios-group=nagios
 make
 make install
 cd $path
 tar -zxvf nrpe-2.12.tar.gz
 cd nrpe-2.12
 ./configure
 make all
 make install
 make install-plugin
 make install-daemon
 make install-daemon-config
 make install-xinetd
 read -p " Please input the nagios server IP: " serverip
 echo "nrpe            5666/tcp                        #nrpe" >> /etc/services
 sed -i "s#only_from.*#only_from       = 127.0.0.1 $serverip#" /etc/xinetd.d/nrpe
 chkconfig --add xinetd
 chkconfig xinetd on
 cd $path
 tar -zxvf check_mysql_health-2.1.tar.gz
 cd check_mysql_health-2.1
 ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios --with-perl=/usr/bin/perl
 make
 make install
 yum install perl-DBI perl-DBD-MySQL -y
 cd $path
 tar -zxvf check_iftraffic.tar.gz
 chmod +x check_iftraffic
 chmod +x check_mem.sh
 chmod +x check_cpu.sh
 chmod +x ip_conn.sh
 cp check_mem.sh /usr/local/nagios/libexec
 cp check_cpu.sh /usr/local/nagios/libexec
 cp check_iftraffic /usr/local/nagios/libexec
 cp ip_conn.sh /usr/local/nagios/libexec
 read -p "please input the mysql password: " mysqlpwd
 read -p "please input the nagios for mysql's password: " nagiospwd
 mysql -uroot -p$mysqlpwd -e "create database nagios;"
 mysql -uroot -p$mysqlpwd -e "grant select on nagios.* to nagios@'$serverip' identified by '$nagiospwd' ;"
 mysql -uroot -p$mysqlpwd -e "flush privileges; "
 cp $path/cfg/nrpe.cfg /usr/local/nagios/etc/
 chown -R nagios.nagios /usr/local/nagios
 service xinetd restart
 echo "##############################"
 echo "#########**the result**#######"
 lsof -i:5666
 echo "------------------------------"
 /usr/local/nagios/libexec/check_nrpe -H localhost
 }

下面是web端部署的脚本

 

installweb () {
 yum install xinetd -y
 service xinetd start
 cd $path
 useradd -s /sbin/nologin nagios
 tar -zxvf nagios-plugins-1.4.14.tar.gz
 cd nagios-plugins-1.4.14
 ./configure --prefix=$nagiospath --with-nagios-user=nagios --with-nagios-group=nagios
 make
 make install
 cd $path
 tar -zxvf nrpe-2.12.tar.gz
 cd nrpe-2.12
 ./configure
 make all
 make install
 make install-plugin
 make install-daemon
 make install-daemon-config
 make install-xinetd
 read -p " Please input the nagios server IP: " serverip
 echo "nrpe            5666/tcp                        #nrpe" >> /etc/services
 sed -i "s#only_from.*#only_from       = 127.0.0.1 $serverip#" /etc/xinetd.d/nrpe
 chkconfig --add xinetd
 chkconfig xinetd on
 cd $path
 tar -zxvf check_iftraffic.tar.gz
 chmod +x check_iftraffic
 chmod +x check_mem.sh
 chmod +x check_cpu.sh
 chmod +x ip_conn.sh
 cp check_mem.sh /usr/local/nagios/libexec
 cp check_cpu.sh /usr/local/nagios/libexec
 cp check_iftraffic /usr/local/nagios/libexec
 cp ip_conn.sh /usr/local/nagios/libexec
 cp $path/cfg/nrpe.cfg /usr/local/nagios/etc/nrpe.cfg
 chown -R nagios.nagios /usr/local/nagios
 service xinetd restart
 echo "###################################"
 echo "#########    the result    ########"
 echo "-----------------------------------"
 lsof -i:5666
 echo "-----------------------------------"
 /usr/local/nagios/libexec/check_nrpe -H localhost
 }

验证安装是否成功的方式，与第一篇相同

还是得手敲（悲剧）！！

 

这样就可以了
