第 2 章 Nagios 内核安装和配置

流程

1. 安装先决条件：

   [user@nagios]# yum install -y httpd php php-cli gcc glibc glibc-common gd gd-devel net-snmp openssl openssl-devel wget unzip

2. 为 httpd 打开端口 80:

   [user@nagios]# firewall-cmd --zone=public --add-port=80/tcp
   [user@nagios]# firewall-cmd --zone=public --add-port=80/tcp --permanent

3. 为 Nagios Core 创建用户和组：

   [user@nagios]# useradd nagios
   [user@nagios]# passwd nagios
   [user@nagios]# groupadd nagcmd
   [user@nagios]# usermod -a -G nagcmd nagios
   [user@nagios]# usermod -a -G nagcmd apache

4. 下载 Nagios Core 和 Plug-ins 的最新版本：

   [user@nagios]# wget --inet4-only https://assets.nagios.com/downloads/nagioscore/releases/nagios-4.3.1.tar.gz
   [user@nagios]# wget --inet4-only http://www.nagios-plugins.org/download/nagios-plugins-2.2.1.tar.gz
   [user@nagios]# tar zxf nagios-4.3.1.tar.gz
   [user@nagios]# tar zxf nagios-plugins-2.2.1.tar.gz
   [user@nagios]# cd nagios-4.3.1

5. run ./configure:

   [user@nagios]# ./configure --with-command-group=nagcmd

6. 编译 Nagios 核心源代码：

   [user@nagios]# make all

7. 安装 Nagios 源代码：

   [user@nagios]# make install
   [user@nagios]# make install-init
   [user@nagios]# make install-config
   [user@nagios]# make install-commandmode
   [user@nagios]# make install-webconf

8. 复制事件处理程序并更改其所有权：

   [user@nagios]# cp -R contrib/eventhandlers/ /usr/local/nagios/libexec/
   [user@nagios]# chown -R nagios:nagios /usr/local/nagios/libexec/eventhandlers

9. 运行 pre-flight 检查：

   [user@nagios]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

10. 创建并安装 Nagios Core 插件：

    [user@nagios]# cd ../nagios-plugins-2.2.1
    [user@nagios]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios
    [user@nagios]# make
    [user@nagios]# make install

11. 为 Nagios Core 用户界面创建一个用户：

    [user@nagios]$ sudo htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

    重要

    如果添加 nagiosadmin 以外的用户，请确保 /usr/local/nagios/etc/cgi.cfg 文件也使用用户名更新。

    另外，根据需要使用用户名、全名和电子邮件地址修改 /usr/local/nagios/etc/objects/contacts.cfg 文件。

12. run ./configure:

    [user@nagios]# ./configure --with-command-group=nagcmd

13. 编译 Nagios 核心源代码：

    [user@nagios]# make all

14. 安装 Nagios 源代码：

    [user@nagios]# make install
    [user@nagios]# make install-init
    [user@nagios]# make install-config
    [user@nagios]# make install-commandmode
    [user@nagios]# make install-webconf

15. 复制事件处理程序并更改其所有权：

    [user@nagios]# cp -R contrib/eventhandlers/ /usr/local/nagios/libexec/
    [user@nagios]# chown -R nagios:nagios /usr/local/nagios/libexec/eventhandlers

16. 运行 pre-flight 检查：

    [user@nagios]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
