agios安装文档

1、 Nagios安装与配置安装环境：centos-5.5Nagios是一款用于系统和网络监控的应用程序。它可以在你设定的条件下对主机和服务进行监控，在状态变差和变好的时候给出告警信息。安装apache,php前提：#yum y install *gcc*安装freetype (FreeType库是一个 开源的、高质量的且可移植的字体引擎)# tar -zxvf freetype-2.4.3.tar.gz -C /usr/src/# cd /usr/src/freetype-2.4.3/# ./configure -prefix=/usr/local/freetype-2.4.3# make# m

2、ake install安装libpng (支持对 PNG 图形文件的创建、读写等操作)# tar -zxvf libpng-1.4.4.tar.gz -C /usr/src/# cd /usr/src/libpng-1.4.4/# ./configure -prefix=/usr/local/libpng-1.4.4# make# make install3、安装jpeg (显示JPEG图像)# tar -zxvf jpegsrc.v8b.tar.gz -C /usr/src/# cd /usr/src/jpeg-8b/# ./configure -prefix=/usr/local/jpeg

3、-8b# make# make install安装GD库重新加载 lib # ldconfig# ldconfig -p | grep jpeg# ldconfig -p | grep free# ldconfig -p | grep libpng# tar -zxvf gd-2.0.33.tar.gz -C /usr/src/# cd /usr/src/gd-2.0.33/# ./configure -prefix=/usr/local/gd-2.0.33 -with-jpeg=/usr/local/jpeg-8b/ -with-freetype=/usr/local/freetype-2.

4、4.3/ -with-png=/usr/local/libpng-1.4.4/ -with-zlib -enable-m4_pattern_allow解决方法：# vim gd_png.c找到png.h 改为 /usr/local/libpng-1.4.4/include/png.h# make# make install安装apache# rpm -e httpd -nodeps 把rpm安装的httpd包卸载# tar -zxvf httpd-2.2.15.tar.gz -C /usr/src/# cd /usr/src/httpd-2.2.15/# ./configure -prefix

5、=/usr/local/apache-2.2.15 -enable-so -enable-rewrite# make# make install安装php# tar -zxvf php-5.2.10.tar.gz -C /usr/src/# cd /usr/src/php-5.2.10/# ./configure -prefix=/usr/local/php-5.2.10 -with-apxs2=/usr/local/apache-2.2.15/bin/apxs -with-zlib -with-libxml-dir -enable-gd-native-ttf -enable-mbstring

6、 -with-gd=/usr/local/gd-2.0.33/ -with-freetype-dir=/usr/local/freetype-2.4.3/ -with-jpeg-dir=/usr/local/jpeg-8b/ -with-png-dir=/usr/local/libpng-1.4.4/解决方法：放入系统光盘 yum y install libxml2* libxml2是一个xml C语言的解析器和工具# make# make test# make install Apaceh与php整合# vim /usr/local/apache/conf/httpd.conf53 Load

7、Module php5_module modules/libphp5.so54 AddType application/x-httpd-php .php167 168 DirectoryIndex index.php index.html169 解决方法：# make clean # /usr/src/php- php-5.2.10#make install解决方法：重新make之前要make clean# /usr/local/apache/bin/apachectl start验证：HYPERLINK http:/localhosthttp:/localhost安装nagios1、创建系统

8、用户# useradd nagios# passwd nagios# groupadd nagcmd# usermod -G nagcmd nagios# usermod -G nagcmd apache安装nagios# tar -zxvf nagios-3.1.2.tar.gz -C /usr/src/# cd /usr/src/nagios-3.1.2/# ./configure -with-command-group=nagcmd# make all# make install# make install-init# make install-config# make install-

9、commandmode 修改配置文件：# vim /usr/local/nagios/etc/objects/contacts.cfg35 email HYPERLINK mailto: 更改email接收报警内容# make install-webconf 安装nagios的web配置文件到apache的conf.d目录下/usr/bin/install: 无法创建一般文件“/etc/httpd/conf.d/nagios.conf”: 没有那个文件或目录make: * install-webconf 错误 1解决方法以：# mkidr p /etc/httpd/conf.d# vim /u

10、sr/local/apache/conf/httpd.conf: -r /etc/httpd/conf.d/nagios.conf 将文件导入到apache配置文件中# /usr/local/apache/bin/apachectl start 启动apache# /usr/local/apache/bin/htpasswd -c /usr/local/nagios/etc/htpasswd.users test 创建登录nagios用户3、安装插件1）、nagios-plugis# tar -zxvf nagios-plugins-1.4.14.tar.gz -C /usr/src/# cd

11、 /usr/src/nagios-plugins-1.4.14/# ./configure -with-nagios-user=nagios -with-nagios-group=nagios# make# make install到此，nagios已经安装完成,需要做以下设置，启动Nagios# chkconfig add nagios 将nagios添加到服务中# chkconfig nagios on 设置服务开机启动# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 检查nagios配置是否正确# ser

12、vice nagios start 启动nagios# setenforce 0 关闭selinux验证：http:/localhost/nagios解决方法：# vim /usr/local/nagios/etc/cgi.cfg78 use_authentication=0# service nagios restart(修改nagios侧边栏 /usr/local/nagios/share/side.php)Nagios配置文件# cd /usr/local/nagios/etc/# ll总计 88-rw-rw-r- 1 nagios nagios 11408 06-16 16:39 cg

13、i.cfgCGI配置文件 -rw-r-r- 1 root root 36 06-16 17:58 htpasswd.usersApache 验证密码文件-rw-rw-r- 1 nagios nagios 43825 06-17 00:55 nagios.cfgNagios 主配置文件drwxrwxr-x 2 nagios nagios 4096 06-17 01:39 objects监控对象定义文件目录-rw-rw- 1 nagios nagios 1340 06-16 00:45 resource.cfgNagios 资源配置文件Nagios主配置文件vim /usr/local/nagio

14、s/etc/nagios.cfglog_file=/usr/local/nagios/var/nagios.log nagios日志文件cfg_file=/usr/local/nagios/etc/objects/commands.cfg命令配置文件cfg_file=/usr/local/nagios/etc/objects/contacts.cfg联系人配置文件cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg时间周期配置文件cfg_file=/usr/local/nagios/etc/objects/templates.cfg模板配

15、置文件cfg_file=/usr/local/nagios/etc/objects/localhost.cfg默认监控本机的配置cfg_file=/usr/local/nagios/etc/objects/windows.cfg监控windows配置文件nagios监控linux服务器服务器：centos 5.5 nagios nagios-plugis nrpe客户端：centos 5.5 nagios-plugins nrpe因为监控都是依靠插件去完成的，而监控linux主要使用nrpe插件服务器端安装nrpe# tar -zxvf nagios-nrpe_2.8.1.orig.tar.g

16、z -C /usr/src/# rpm -qa | grep sslopenssl-0.9.8e-12.el5_4.6# cd /usr/src/nrpe-2.8.1/# ./configure -enable-ssl -with-ssl-lib=/lib/configure: error: Cannot find ssl libraries解决方法：# yum -y install openssl-devel# make all# make install-plugin# vim /usr/local/nagios/etc/objects/commands.cfg# 添加#check nrp

17、edefine command command_name check_nrpe command_line $US ER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ # vim /usr/local/nagios/etc/nagios.cfg 配置要监控的linux主机添加：37 cfg_file=/usr/local/nagios/etc/objects/mylinux.cfg# vim /usr/local/nagios/etc/objects/mylinux.cfg 新建监控内容define host use linux-server host_name

18、 mylinux alias mylinux address 1(客户端IP既被监控的IP) define service use generic-service host_name mylinux service_description check-swap check_command check_nrpe!check_swap define service use generic-service host_name mylinux service_description check-load check_command check_nrpe!check_load define servic

19、e use generic-service host_name mylinux service_description check-disk check_command check_nrpe!check_had1define service use generic-service host_name mylinux service_description check-users check_command check_nrpe!check_users define service use generic-service host_name mylinux service_description

20、otal_procs check_command check_nrpe!check_total_procs# service nagios restart客户端配置# useradd nagios# passwd nagios1、安装nagios-plugins# tar -zxvf nagios-plugins-1.4.14.tar.gz -C /usr/src/# cd /usr/src/nagios-plugins-1.4.14/# ./configure -with-nagios-user=nagios -with-nagios-group=nagios# make # make in

21、stall# chown -R nagios.nagios /usr/local/nagios/# cd /usr/local/nagios/2、安装nagios-nrpe# tar -zxvf nagios-nrpe_2.8.1.orig.tar.gz -C /usr/src/# cd /usr/src/nrpe-2.8.1/# ./configure -enable-ssl -with-ssl-lib=/usr/lib# make all# make install-plugin# make install-daemon# make install-daemon-config# vim /

22、usr/local/nagios/etc/nrpe.cfg72 allowed_hosts=# /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg d 启动nrpe# netstat -tulnp | grep 5666 验证nrpe服务器测试# /usr/local/nagios/libexec/check_nrpe -H NRPE v2.8.1客户端配置监控对象# vim /usr/local/nagios/etc/nrpe.cfg这一步是关键,如果nagios服务器想要监控客户机swap分区,但客户机nrpe.cfg文件没有swap监控对像,这时监控服务器就是报错(NRPE command check_swapno defined)至此，查看nagios监控。客户端已经被加入进来。监控windows客户端客户端安装软件：
