RHEL6 Nagios 部署系统环境:RHEL6 x86_64 selinux and iptables disablednagios 主机:192.168.0.5mysql 主机: 192.168.0.1一，监控本机安装所需要软件yum install httpd gcc make perl-ExtUtils-Embed.x86_64 -yrpm -ivh gd-devel-2.0.35-10.el6.x86_64.rpm  useradd nagios                      运行 nagios 服务的用户usermod -G nagios apache          使 apache 用户对 nagios 目录具有写权限,不然 web 页面操作失败 tar jxf nagios-cn-3.2.3.tar.bz2       解压nagioscd nagios-cn-3.2.3./configure –-enable-embedded-perl 编译make allmake installmake install-initmake install-commandmodemake install-configmake install-webconf yum install mysql-devel openssl-devel -y 编译所需软件包tar zxf nagios-plugins-1.4.15.tar.gz       nagios 插件安装cd nagios-plugins-1.4.15./configure —with-nagios-user=nagios —with-nagios-group=nagios--enable-extra-opts —enable-libtap —enable-perl-modulesMake && make install  vi /usr/local/nagios/etc/nagios.cfg              #nagios配置cfg_file=/usr/local/nagios/etc/objects/hosts.cfg #新建 hosts.cfg 文件,存放主机与主机组定义cfg_file=/usr/local/nagios/etc/objects/services.cfg #新建 services.cfg 文件,存放服务与服务组定义#cfg_file=/usr/local/nagios/etc/objects/localhost.cfg#注释 localhost.cfg 文件如下图： 

 cp -r localhost.cfg hosts.cfgvi /usr/local/nagios/etc/objects/hosts.cfg去掉service部分，只留下想要的的hosts部分define host{        use                     linux-server            ; 给网络设备用的        host_name               Desktop5        alias                   nagios        address                 192.168.0.5        2d_coords               100,200        3d_coords               100,200,100        }define hostgroup{        hostgroup_name linux-servers ; The name of the hostgroup        alias           Linux Servers ; Long name of the group        members         *     ; Comma separated list of hosts that belong to this group        }如下图：

 二．监控另外一台机器的数据库（mysql)Yum install mysql* -y/etc/init.d/mysql restartMysqlmysql>create database nagdb;                                        创建用户mysql> grant select on nagdb.* to nagdb@'192.168.0.5';              使其具有查看权限mysql> flush privileges;                                               刷新数库                                                在nagios服务器中查看是否能够链接到mysql主机/usr/local/nagios/libexec/usr/local/nagios/libexec/check_mysql -H 192.168.0.1 -u nagdb -d nagdb 

在 nagios 主机上添加对 mysql 服务监控的定义vi /usr/local/nagios/etc/objects/commands.cfg       （添加如下行）define command{         command_name   check_mysql       command_line   $USER1$/check_mysql -H $HOSTADRESS$ -u nagdb -d nagdb}vi /usr/local/nagios/etc/objects/hosts.cfg            (添加如下行)   define host{       use                     linux-server       host_name               mysql服务器       alias                   Desktop1       address                 192.168.0.1       2d_coords                500,200       3d_coords               500,200,100}vi /usr/local/nagios/etc/objects/services.cfg （添加如下行）define service{        use                           local-service        host_name                      mysql服务器        check_command                 check_mysql } /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg/etc/init.d/httpd restart/etc/init.d/ngios restart就能访问http://192.168.0.5/nagio 

     三．Nagios 通过 NRPE 监控远程主机系统状况  

 

 远程主机设定useradd nagios tar xzf nagios-plugins-1.4.15.tar.gzcd nagios-plugins-1.4.15./configure —with-nagios-user=nagios --with-nagios-group=nagios --enable-extra-opts --enable-perl-modules —with-openssl --enable-libtap makemake install yum install xinetd -y tar zxf nrpe-2.12.tar.gzcd nrpe-2.12./configuremake allmake install-pluginmake install-daemonmake install-daemon-configmake install-xinetd vi /etc/xinetd.d/nrpe 修改如下行only_from= 192.168.0.5                        #nagios 主机 ip 地址 vi /etc/services     添加如下行nrpe                5666/tcp                   nrpe务监听端口 vi /usr/local/nagios/etc/nrpe.cfg                 修改如下行command[check_disk]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /#根分区监测service xinetd restartnetstat -antlp |grep 5666tcp 0 0 :::5666#看到如下输出说明 NRPE 正常启动,并确保防火墙允许此端口:::*LISTEN26359/xinetd  监控主机设定tar zxf nrpe-2.12.tar.gzcd nrpe-2.12./configure --with-nagios-user=nagios --with-nagios-group=nagiosmake allmake install-plugin/usr/local/nagios/libexec/check_nrpe -H 192.168.0.1NRPE v2.12#如看到如下输出说明连接正常 vi /usr/local/nagios/etc/objects/commands.cfg 添加如下行define command{command_name       check_nrpecommand_line        $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$} vi /usr/local/nagios/etc/objects/services.cfg 添加如下行define service{        use                           local-service        host_name                     mysql服务器        check_command                 check_mysql        service_description            mysql服务}define service{       use                                generic-service       host_name                          mysql服务器       service_description                CPU 使用率       check_command                      check_nrpe!check_load}define service{       use                                generic-service       host_name                          mysql服务器       service_description                登录用户数量       check_command                      check_nrpe!check_users} define service{        use                               generic-servicehost_name                         mysql服务器service_description                 根使用率check_command                    check_nrpe!check_disk} /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfgservice nagios reload#检测无误后重载 nagios   Nagios 整合飞信
http://www.it-adv.net/ 下载 fetion 主程序与支持库步骤
（1）IP：192.168.0.85：
cd ~
lftp 127.0.0.1
cd /pub/docs/nagios
get fetion cenos54X64_20101113.rar
cd /pub/docs
get rarlinux-3.8.0.tar.gz 
cp fetion /usr/local/nagios/libexec
cd /usr/local/nagios/libexec
chmod +x fetion
chown nagios.nagios fetion
(2)执行 /usr/local/nagios/libexec/fetion
出现没有/lib/ld-linux.so
yum install /lib/ld-linux.so.2 -y
cd /usr/local/nagios/libexec/
./fetion
cd ~
tar zxf rarlinux-3.8.0.tar.gz -C /opt/
cd /opt/rar/unrar
/opt/rar/unrar x cenos54X64_20101113.rar(可能会出错，需要安装以下的包，然后重新执行此步。)yum install libstdc++.so.6
（3） cd ~
lftp 192.168.0.254
cd /pub/docs/nagios
get linuxso_20111113.tar.gz
tar zxf linuxso_20111113.tar.gz -C /usr/local/lib(将库文件放到/usr/local/ib中。ldconfig /usr/local/lib使其生效。)
cd /usr/local/lib
ls 会有4个so文件。
chmod +x *
需要的时候可能需要安装： yum install libgssapi_krb5.so.2 libz.so.1 zlib文件。
ldconfig /usr/local/lib
/usr/local/nagios/libexec/fetion 7执行成功。

（4）vi /etc/ld.so.conf.d/mysql-x86_64.conf
/usr/lib64/mysql
(5) vi fetion.conf
/usr/local/lib
ldconfig
(6) su - nagios
/usr/local/nagios/libexec/fetion --mobile=158029XXXXX --pwd=XXXXXX(飞信密码) --to=15802955XXXX --msg-utf8="hello"
然后你去/usr/local/nagios/libexec找到1509154xxxx.jpg,然后将其复制到桌面，查看其验证码，然后写上去，你就会在1509154xxxx收到一个由mobile=1509154xxxx发来的信息哦！）
你第一次用验证码，第二次就不用验证码。
实验五：
fetion 与 nagios 配置
步骤（1）cd /usr/local/nagios/libexec/
vi fetion.sh
/usr/local/nagios/libexec/fetion --mobile=158029XXXXX --pwd=qqXXXXX --to="$1" --msg-utf8="$2" > /dev/null
(2) chmod +x fetion.sh
chown ngios.nagios fetion.sh
su - nagios
cd /usr/local/nagios/libexec/
./fetion.sh 1509154xxxx "hello" (测试给1509154xxxx发送小心“hello“)
此时因为你重新调用的程序，需要重新找到验证码并输入.....
然后就可以收到信息喽......
(3) cd /usr/local/nagios/etc/objects/
vi templates.cfg

Generic contact definition template - This is NOT a real contact, just a template!define contact{
name generic-contact ; The name of this contact template
.
.
.
service_notification_commands notify-service-by-email,notify-service-by-fetion ; send service notifications via email
host_notification_commands notify-host-by-email,notify-host-by-fetion ; send host notifications via email
..........................
}
(4) vi /usr/local/nagios/etc/objects/commands.cfg
增加以下内容：
# 'notify-host-by-fetion' command definition
define command{
command_name notify-host-by-fetion
command_line $USER1$/fetion.sh $CONTACTPAGER$ "$NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$"
}
# 'notify-service-by-fetion' command definition
define command{
command_name notify-service-by-fetion
command_line $USER1$/fetion.sh $CONTACTPAGER$ "$NOTIFICATIONTYPE$: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$"
}
（5）vi /usr/local/nagios/etc/objects/contacts.cfg

define contact{
.
.
.
email 997365139@qq.com ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ******
pager 1509154xxxx(接收飞信信息的手机号码
)
}
（6）测试：
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
#校验后重新载入 nagios 配置
/etc/init.d/nagios reload
此时你若把被监控端的： service mysqld stop此时会产生报警。然后下次检测的时候你的手机和邮箱会同时收到邮件和信息哦。。
