- 安装nagios
|
[aaa@qq.com nagios]# cd software/ [aaa@qq.comios software]# tar zxvf nagios-3.5.0.tar.gz [aaa@qq.com software]# cd nagios [aaa@qq.com nagios]# ./configure --prefix=/home/nagios/nagios [aaa@qq.com nagios]# make all [aaa@qq.com nagios]# make install 安装主要程序，CGI及HTML文件 [aaa@qq.com nagios]# make install-init 把nagios做成运行脚本，nagios随开机启动 [aaa@qq.com nagios]# make install-commandmode 给外部命令访问nagios配置文件的权限 [aaa@qq.com nagios]# make install-config 把配置文件的例子复制到nagios的安装目录
|
- 验证程序是否正确安装
|
[aaa@qq.com nagios]# ll 总计 24 drwxrwxr-x 2 nagios nagios 4096 05-06 10:11 bin drwxrwxr-x 3 nagios nagios 4096 05-06 10:13 etc drwxrwxr-x 2 nagios nagios 4096 05-06 10:11 libexec drwxrwxr-x 2 nagios nagios 4096 05-06 10:11 sbin drwxrwxr-x 10 nagios nagios 4096 05-06 10:11 share drwxrwxr-x 5 nagios nagios 4096 05-06 10:12 var |
如果etc、bin、 sbin、 share、 var、libexec六个目录存在，则表明程序被正确安装，下边是六个目录功能的简要说明：
|
etc |
Nagios配置文件位置，包括*.cfg文件，对象模板，密码文件 |
|
bin |
Nagios执行程序所在目录，这个目录只有两个文件nagios，nagiostats |
|
sbin |
Nagios Cgi文件所在目录，也就是执行外部命令所需文件所在的目录 |
|
share |
Nagios网页文件所在的目录 |
|
var |
Nagios日志文件、spid 等文件所在的目录 |
|
libexec |
Nggios插件安装目录，未装插件之前此目录为空 |

[Yns]: n [aaa@qq.com php-5.4.13]# make install |
注意：PHP应该在apache之后安装，否则无法在apache的modules下生成libphp5.so文件，导致不能登录页面。
- 配置Apache
- 编辑apache/conf/httpd.conf文件
|
[aaa@qq.com conf]# vi httpd.conf
User example Group example 改为 User nagios Group nagios
<IfModule dir_module> DirectoryIndex index.html </IfModule> 改为 <IfModule dir_module> DirectoryIndex index.php index.html </IfModule>
[aaa@qq.com nagios]# chown -R nagios:nagios apache/ [aaa@qq.com nagios]# chown -R nagios:nagios nagios/

- 生成用户验证文件
|
[aaa@qq.com nagios]# /home/nagios/apache/bin/htpasswd -c /home/nagios/nagios/etc/htpasswd jsbzb New password: Re-type new password: Adding password for user jsbzb
修改生成的密码文件的用户和属组 [aaa@qq.com nagios]# cd nagios/etc/ [aaa@qq.com etc]# chown nagios:nagios htpasswd |
疑问：密码中不能有字母，否则无法登录，只能用数字。
- 启动nagios和apache并登录
- apache配置完成后执行如下命令，检查配置是否正确
|
[aaa@qq.com etc]# /home/nagios/apache/bin/apachectl -t Syntax OK |
- 用root用户启动nagios和apache
|
[aaa@qq.com nagios]# ./apache/bin/apachectl start& [aaa@qq.com nagios]# service nagios start |
- 至此，nagios安装完成，验证配置
在浏览器中输入地址：http://192.168.19.29/nagios，出现下图登录等待窗口，输入之前创建的用户和密码登录。
登录成功后进入nagios首页
- 安装nagios的snmp采集插件
nagios-snmp-plugins是一套用Perl编写的通过SNMP方式监控主机的插件程序。
配置check_snmp_int.pl这些插件的使用时需要配置cpan，CPAN是Comprehensive Perl Archive Network的缩写.。它是一个巨大的Perl软件收藏库，收集了大量有用的Perl模块(modules)及其相关的文件。这里主要是使用Perl-Net-SNMP模块。
- 安装Perl-Net-SNMP模块
有两种方式安装：
A）通过CPAN来安装
|
#perl -MCPAN -e shell cpan> install Net::SNMP |
B) 手工安装
首先去官方网站下载以下几个模块：
|
Crypt::DES Digest::MD5 Digest::SHA1 Digest::HMAC Net::SNMP |
下载后对于每个模块依次按照下面的方式安装
|
#tar zxvf *.tar.gz 表示模块名，具体请按上面提到的模块替换 #cd 表示模块名，具体请按上面提到的模块替换 #perl Makefile.pl #make test #make install |
注意：Net::SNMP模块必须在最后安装。至此Net::SNMP手动安装完毕
- 安装snmp采集插件
|
[aaa@qq.com software]# tar zxvf nagios-snmp-plugins.1.1.1.tgz [aaa@qq.com software]# cd nagios_plugins [aaa@qq.com nagios_plugins]# ./install.sh |
- 安装配置NRPE（for linux）
Nagios nrpe 能够实现调用远程主机上的nagios插件及其脚本来实现远程监控。
- 服务器端安装nrpe插件
|
[aaa@qq.com Client]# tar zxvf nrpe-2.14.tar.gz [aaa@qq.com Client]# cd nrpe-2.14 [aaa@qq.com nrpe-2.14]# ./configure --prefix=/home/nagios/nagios [aaa@qq.com nrpe-2.14]# make all [aaa@qq.com nrpe-2.14]# make install-plugin [aaa@qq.com nrpe-2.14]# cd /home/nagios/nagios/libexec/ [aaa@qq.com libexec]# ll 总计 6812 -rwxr-xr-x 1 nagios nagios 382372 05-07 17:23 check_apt -rwxr-xr-x 1 nagios nagios 2247 05-07 17:23 check_breeze -rwxr-xr-x 1 nagios nagios 159218 05-07 17:23 check_by_ssh lrwxrwxrwx 1 nagios nagios 9 05-07 17:23 check_clamd -> check_tcp -rwxr-xr-x 1 nagios nagios 112929 05-07 17:23 check_cluster -rwxrwxr-x 1 nagios nagios 65885 05-08 10:37 check_nrpe ………省略 |
Nagios只要拥有NRPE的扩展插件功能就可以了，所以在Nagios监测服务器安装NRPE工作到这步就可以了。
- 客户端安装nrpe插件
Nrpe插件依赖于gcc、openssl、openssl-devel三个包，如果没有需要先安装。
|
检查 rpm –q gcc rpm –q openssl openssl-devel 安装 yum -y install gcc gcc-c++ yum -y install openssl openssl-devel |
创建nagios用户
|
[aaa@qq.com ~]# groupadd -g 501 nagios [aaa@qq.com ~]# useradd -u 500 -g nagios nagios [aaa@qq.com ~]# passwd nagios nagios用户密码统一使用：zzb1201 |
拷贝以下三个文件到客户端，从服务器（192.168.19.29）下载以下程序
|
服务器目录：/home/nagios/software/Client nagios-plugins-1.4.16.tar.gz nrpe-2.14.tar.gz check_linux_stats.pl Sys-Statistics-Linux-0.66.tar.gz |

- 网络设备监控配置(Cisco)
简介：此处以Cisco为例，其它网络设备检控命令可能需要调整。Cisco交换机都支持SNMP协议，只需要简单的设置即可开启。在安装Nagios之前，必须已经安装Net-Utils及其开发组件，参考本文第十步。由于使用check_snmp检测的结果不够人性化，大部分的结果都需要重新调整。使用Perl脚本调用NET::SNMP模块，实现收集监控结果，并重新输出，更易阅读和使用。
比较好的perl脚本有如下几个
|
从服务器（192.168.19.29）的目录/home/nagios/software/net_perl下载 check_snmp_cisco_loadavg.pl check_snmp_cisco_memutil.pl check_snmp_cisco_ifstatus.pl check_snmp_int.pl check_snmp_env.pl |
监控服务器端配置步骤：
- 增加perl脚本
chown nagios:nagios check_snmp_cisco_*.pl chmod 755 check_snmp_cisco_*.pl |
- 编辑命令配置文件commands.cfg，增加网络监控命令
|
vi nagios/etc/objects/commands.cfg
#net command add by wangyong 20130514
define command{ command_name check_snmp_cisco_loadavg command_line $USER1$/check_snmp_cisco_loadavg.pl -H $HOSTADDRESS$ $ARG1$ }
define command{ command_name check_snmp_cisco_memutil command_line $USER1$/check_snmp_cisco_memutil.pl -H $HOSTADDRESS$ $ARG1$ }
define command{ command_name check_snmp_cisco_ifstatus command_line $USER1$/check_snmp_cisco_ifstatus.pl -H $HOSTADDRESS$ $ARG1$ }
define command{ command_name check_snmp_int command_line $USER1$/check_snmp_int.pl -H $HOSTADDRESS$ $ARG1$ }
define command{ command_name check_snmp_env command_line $USER1$/check_snmp_env.pl -H $HOSTADDRESS$ $ARG1$ } |
- 添加网络主机对象
|
如果是第一次添加，在nagios/etc/objects目录下创建自己的对象目录 [aaa@qq.com objects]$ mkdir zhangs 进入zhangs目录，创建网络设备对象 vi zhangs-cisco2950-switch.cfg
define host{ use generic-switch host_name zhangs-cisco2950-switch alias zhangs-cisco2950-switch address 192.168.16.160(交换机地址) }

- 配置服务器端服务
参考十一章节第4小节
- 安装配置check_mssql_health
- 安装check_mssql_health
|
[aaa@qq.com mssqlserver]# tar zxvf check_mssql_health-1.5.19.1.tar.gz [aaa@qq.com mssqlserver]# cd check_mssql_health-1.5.19.1 [aaa@qq.com check_mssql_health-1.5.19.1]# ./configure --prefix=/home/nagios/nagios --with-nagios-user=nagios --with-nagios-group=nagios [aaa@qq.com check_mssql_health-1.5.19.1]# make && make install
[aaa@qq.com libexec]# chown nagios:nagios /home/nagios/nagios/libexec/check_mssql_health |
- 安装、配置freetds-0.82
说明：在linux下连接MSSQL比较困难，微软没有提供任何接口给开发人员。还好，MSSQL是从Sybase衍生出来的，有些人做了Sybase的Linux下的连接库，这些连接库同时也能支持MSSQL，FreeTDS就是这样的一个软件。
- 安装freetds-0.82
|
[aaa@qq.com mssqlserver]# tar xvzf freetds-0.82.tar.gz [aaa@qq.com mssqlserver]# cd freetds-0.82 [aaa@qq.com freetds-0.82]# ./configure --prefix=/usr/local/freetds --with-tdsver=8.0 --enable-msdblib [aaa@qq.com freetds-0.82]# make && make install |
- 配置freetds-0.82
配置root用户环境变量
|
[aaa@qq.com ~]# vi .bash_profile
SYBASE=/usr/local/freetds FREETDS_HOME=/usr/local/freetds PATH=$FREETDS_HOME/bin:$PATH
export SYBASE FREETDS_HOME PATH export LD_LIBRARY_PATH=/usr/local/freetds/lib/
[aaa@qq.com ~]# source .bash_profile |
配置sql servers
|
Vi /usr/local/freetds/etc/freetds.conf
#juyuan1 sql server [server_juyuan1] host = 172.16.84.31 port = 1433 tds version = 7.0 |
增加 /usr/local/freetds/lib 到 /etc/ld.so.conf, 然后，运行ldconfig
|
[aaa@qq.com ~]# vi /etc/ld.so.conf
include ld.so.conf.d/*.conf /usr/local/freetds/lib
[aaa@qq.com ~]# ldconfig |
如果不增加/usr/local/freetds/lib，手工执行命令成功，但是nagios自动运行失败，错误如下：
|
cannot connect to xxx.xxx.xxx.xxx. install_driver(Sybase) failed: Can't load '/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/DBD/Sybase/Sybase.so' for module DBD::Sybase: libct.so.4: 无法打开共享对象文件: 没有那个文件或目录 at /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/DynaLoader.pm line 230. |
- 安装DBI和DBD-Sybase
|

- 测试连接
|
[aaa@qq.com ~]# cd /home/nagios/nagios/libexec [aaa@qq.com libexec]# ./check_mssql_health --server=serve_juyuan2 --username=sa --password=xxx --mode=connected-users OK - 6 connected users | connected_users=6;50;80
或 这种方法绕过了配置文件（/usr/local/freetds/etc/freetds.conf） [aaa@qq.com libexec]# ./check_mssql_health --hostname=192.168.16.157 -port=1433 --username=sa --password=xxx --mode=connected-users |
- 添加模板
|
# 'check_mssql_health ' command definition define command{ command_name check_mssql_health command_line $USER1$/check_mssql_health $ARG1$ } |
- 添加服务
|
define service { host_name liy-juyuan2-win2003 service_description Check Sqlserver Users use generic-service check_command check_mssql_health! --server=server_juyuan2 --username=sa --password=1234juyuan --mode=connected-users servicegroups liy-windows-services contact_groups liy-cg } |
