Nagios3.x全攻略——（一）Nagios安装

平台CentOS 首先检查机器环境，安装Nagios需要以下环境 Apache GCC compiler GD development libraries 如果没有可以运行 yum install httpd yum install gcc yum install glibc glibc-common yum install gd gd-devel （本人未测试） 1）添加用户(非常重要，否则你可能会遇到权限问题) /usr/sbin/useradd -m nagios /usr/sbin/groupadd nagcmd /usr/sbin/usermod -G nagcmd nagios /usr/sbin/usermod -G nagcmd apache（此组为运行apache的组） 2）下载Nagios及其插件 cd /usr/local/src wget http://osdn.dl.sourceforge.net/sourceforge/nagios/nagios-3.0.2.tar.gz wget http://osdn.dl.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.11.tar.gz （请替换软件版本号为最新） 3)编译并安装Nagios ./configure --with-command-group=nagcmd （默认安装目录为/usr/local/nagios） make all make install make install-init make install-config make install-commandmode 这时请不要启动Nagios,接下来有很多工作要做…… 4）定制配置文件 vi /usr/local/nagios/etc/objects/contacts.cfg 添加你自己的电子邮件地址，请注意本机DNS设置是否正常 5）配置WEB接口 在apache conf.d目录中安装Nagios web配置文件 make install-webconf 创建nagiosadmin帐号，添加密码 htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin 重新加载Apache配置文件 service httpd graceful 6）编译安装nagios plus cd /usr/local/src tar xzf nagios-plugins-1.4.11.tar.gz cd nagios-plugins-1.4.11 编译安装Nagios plug ./configure --with-nagios-user=nagios --with-nagios-group=nagios make make install 7)启动Nagios 使Nagio开机自启动 chkconfig --add nagios chkconfig nagios on 检查Nagios配置文件 /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 如果没有报错 启动Nagios service nagios start 9）登录web管理界面 http://localhost/nagios/ 输入nagiosadmin 用户名，密码 [table=98%,#ffffff] Nagios3.x全攻略——（二）NRPE安装 [table=98%] Nagios使用NRPE插件监控远程Linux主机 a)远程主机安装 i.创建用户 /usr/sbin/useradd nagios ii.安装nagios plus cd /usr/local/src wget http://osdn.dl.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.6.tar.gz tar xzf nagios-plugins-1.4.6.tar.gz cd nagios-plugins-1.4.6 ./configure make make install chown nagios.nagios /usr/local/nagios chown -R nagios.nagios /usr/local/nagios/libexec iii.安装NRPE cd /usr/local/src wget http://osdn.dl.sourceforge.net/sourceforge/nagios/nrpe-2.8.tar.gz ./configure make all make install-plugin make install-daemon make install-daemon-config iv.启动NRPE vi /usr/local/nagios/etc/nrpe.cfg allowed_hosts=127.0.0.1,Monitoring Host ip 加入监控主机的IP地址,中间用逗号分隔 运行NRPE daemon /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d v.测试NRPE daemon netstat -ln |grep 5666 tcp        0      0 0.0.0.0:5666                0.0.0.0:*                   LISTEN 如果显示以上信息,it's OK!如果没有,请检查系统日志文件 /usr/local/nagios/libexec/check_nrpe -H localhost 如果正常,则显示 NRPE v2.8 vi.修改防火墙规则,开放tcp 5666端口 b)监控主机安装 i.安装check_nrpe plugin cd /usr/local/src wget http://osdn.dl.sourceforge.net/sourceforge/nagios/nrpe-2.8.tar.gz ./configure make all make install-plugin ii.测试远程主机 /usr/local/nagios/libexec/check_nrpe -H remote host ip 如果正常,则显示 NRPE v2.8 否则请检查 -本机防火墙规则 -远程主机nrpe daemon是否工作正常 -远程主机防火墙规则

Nagios3.x全攻略——（三）NSClient++安装

Nagios使用NSClient++监控远程Windows主机 1.下载NSClient++ http://sourceforge.net/projects/nscplus 2.解压下载文件到C:\NSClient++ 3.在CMD命令行下进入C:\NSClient++目录执行 nsclient++ /install 4.在服务中确定NSClient++可以与桌面交互 5.编辑nsc.ini FileLogger.dll CheckSystem.dll CheckDisk.dll NSClientListener.dll ;NRPEListener.dll ;SysTray.dll CheckEventLog.dll CheckHelpers.dll ;CheckWMI.dll [NSClient] ;# ALLOWED HOST ADDRESSES ;  This is a comma-delimited list of IP address of hosts that are allowed to talk to NSClient deamon. ;  If you leave this blank the global version will be used instead. allowed_hosts=your nagios monitoring server's IP ;  This is the port the NSClientListener.dll will listen to. port=12489 6进入CMD命令行，启动NSClient++ nsclient++ /start netstat -an 如果看到以下信息说明成功 TCP    0.0.0.0:12489            0.0.0.0:0              LISTENING

我在客户端服务器上安装nagios-plugin的时候居然编译报错了。
请教一下，我装nagios-3.0.2.tar.gz的时候没有出现问题，但是装nagios-plugins的时候，发现如下问题：
configure没有问题，但是make的时候出现：

目前我在虚拟机上能安装，与虚拟机相比，实际运行环境中原本安装了rpm的mysql，虚拟机中没有。我后来直接安装了mysql的tar，把原有的rpm换走了，实际环境中换的mysql源代码包与虚拟机中所用的mysql也是一样的。
