Nagios服务器端安装部署详解(1)
下载地址如下： http://sourceforge.net/projects/nagios/files/
具体详细下载地址：http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-4.0.6.tar.gz1 开始下载：
wget http://sourceforge.net/projects/nagios/files/nagios-4.x/nagios-4.0.6/nagios-4.0.6.tar.gz/download?use_mirror=jaist
如下图所示，下载free版本的。

安装前准备工作，安装一些lib包：
[root@cache-2 root]# yum -y install httpd gcc glibc glibc-common
# yum install -y gcc glibc glibc-common gd gd-devel xinetd openssl-devel
2 进行selinux设置，或者关闭selinux
查看SELinux状态：
(1)/usr/sbin/sestatus -v ##如果SELinux status参数为enabled即为开启状态
SELinux status: enabled
(2)getenforce ##也可以用这个命令检查
关闭SELinux：
(3)临时关闭（不用重启机器）：
setenforce 0 ##设置SELinux 成为permissive模式
##setenforce 1 设置SELinux 成为enforcing模式
(4)修改配置文件需要重启机器：
修改/etc/selinux/config 文件
将SELINUX=enforcing改为SELINUX=disabled
重启机器即可
3 开始准备nagios安装环境
(1) 添加nagios运行所需要的用户和组：
groupadd nagcmd
useradd -m nagios
usermod -a -G nagcmd nagios
把apache加入到nagcmd组，以便于在通过web Interface操作nagios时能够具有足够的权限：
# usermod -a -G nagcmd apache
4 编译安装准备
./configure --with-command-group=nagios --prefix=/opt/app/nagios --enable-embedded-perl --with-httpd-conf=/usr/local/apache2/conf
[root@cache-2 nagios-4.0.6]# ./configure --with-command-group=nagios --prefix=/opt/app/nagios --enable-embedded-perl --with-httpd-conf=/usr/local/apache2/conf

Review the options above for accuracy. If they look okay,
type ‘make all‘ to compile the main program and CGIs.
5 开始make安装
5.1 make all
[root@cache-2 nagios-4.0.6]# make all
cd ./base && make
make[1]: Entering directory `/root/nagios-4.0.6/base‘

5.3 make install-config
[root@cache-2 nagios-4.0.6]# make install-config /usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc /usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc/objects /usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/nagios.cfg /usr/local/nagios/etc/nagios.cfg .................................................... /usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/printer.cfg /usr/local/nagios/etc/objects/printer.cfg /usr/bin/install -c -b -m 664 -o nagios -g nagios sample-config/template-object/switch.cfg /usr/local/nagios/etc/objects/switch.cfg *** Config files installed ***
5.4 make install-commandmode
[root@cache-2 nagios-4.0.6]# make install-commandmode /usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/var/rw chmod g+s /usr/local/nagios/var/rw *** External command directory configured *** Remember, these are *SAMPLE* config files. You‘ll need to read the documentation for more information on how to actually define services, hosts, etc. to fit your particular needs.
5.5 make install-init
[root@cache-2 nagios-4.0.6]# make install-init /usr/bin/install -c -m 755 -d -o root -g root /etc/rc.d/init.d /usr/bin/install -c -m 755 -o root -g root daemon-init /etc/rc.d/init.d/nagios *** Init script installed ***
[root@cache-2 nagios-4.0.6]#
加到启动项里面去：
# chkconfig --add nagios
# chkconfig --level 35 nagios on
# chkconfig --list nagios
检查主机配置文件是否正确：
/var/www/nagios/bin/nagios -v /var/www/nagios/etc/nagios.cfg
5.6 Check安装是否正确：
5.6.1说明：
切换目录到安装路径（这里是/usr/local/nagios），看是否存在etc、bin、sbin、share、var 这五个目录，如果存在则可以表明程序被正确的安装到系统了。Nagios 各个目录用途说明如下：
bin Nagios 可执行程序所在目录
etc Nagios 配置文件所在目录
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
libexec Nagios 外部插件所在目录
var Nagios 日志文件、lock 等文件所在的目录
var/archives Nagios 日志自动归档目录
var/rw 用来存放外部命令文件的目录
5.6.2 check
cd /usr/local/nagios
ll
[root@cache-2 nagios-4.0.6]# cd /usr/local/nagios [root@cache-2 nagios]# ll 总用量 24 drwxrwxr-x. 2 nagios nagios 4096 5月 5 15:31 bin drwxrwxr-x. 3 nagios nagios 4096 5月 5 15:32 etc drwxrwxr-x. 2 nagios nagios 4096 5月 5 15:31 libexec drwxrwxr-x. 2 nagios nagios 4096 5月 5 15:31 sbin drwxrwxr-x. 10 nagios nagios 4096 5月 5 15:31 share drwxrwxr-x. 5 nagios nagios 4096 5月 5 15:32 var
5.7 安装nagios插件
wget http://nagios-plugins.org/download/nagios-plugins-2.0.tar.gz
[root@cache-2 ~]# wget http://nagios-plugins.org/download/nagios-plugins-2.0.tar.gz --2014-05-05 15:52:52-- http://nagios-plugins.org/download/nagios-plugins-2.0.tar.gz 正在解析主机 nagios-plugins.org... 72.14.186.43 正在连接 nagios-plugins.org|72.14.186.43|:80... 已连接。 已发出 HTTP 请求，正在等待回应... 200 OK ............................................ 2014-05-05 15:53:00 (373 KB/s) - 已保存 “nagios-plugins-2.0.tar.gz” [2501847/2501847]) [root@cache-2 ~]# tar -xvf nagios-plugins-2.0.tar.gz [root@cache-2 ~]# cd nagios-plugins-2.0 [root@cache-2 ~]#./configure --with-nagios-user=nagios --with-nagios-group=nagios --prefix=/usr/local/nagios --with-mysql [root@cache-2 ~]# make && make install
5.8 安装配置apache和php
(1)安装apache
下载 wget http://archive.apache.org/dist/httpd/httpd-2.4.7.tar.gz
[root@cache-2 ~]# wget http://archive.apache.org/dist/httpd/httpd-2.4.7.tar.gz --2014-05-05 16:15:48-- http://archive.apache.org/dist/httpd/httpd-2.4.7.tar.gz 正在解析主机 archive.apache.org... 192.87.106.229, 140.211.11.131, 2001:610:1:80bc:192:87:106:229 正在连接 archive.apache.org|192.87.106.229|:80... 已连接。 已发出 HTTP 请求，正在等待回应... 200 OK 长度：6747087 (6.4M) [application/x-gzip] 正在保存至: “httpd-2.4.7.tar.gz” 1% [=> .............................................................. 2014-05-05 16:16:01 (574 KB/s) - 已保存 “httpd-2.4.7.tar.gz” [6747087/6747087])
开始安装：
tar -xvf httpd-2.4.7.tar.gz
cd httpd-2.4.7
./configure --prefix=/usr/local/apache2
make && make install
[root@cache-2 ~]# tar -xvf httpd-2.4.7.tar.gz [root@cache-2 ~]# cd httpd-2.4.7 [root@cache-2 httpd-2.4.7]# ./configure --prefix=/usr/local/apache2 checking for chosen layout... Apache checking for working mkdir -p... yes checking for grep that handles long lines and -e... /bin/grep checking for egrep... /bin/grep -E checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type... x86_64-unknown-linux-gnu configure: configure: Configuring Apache Portable Runtime library... configure: checking for APR... no configure: error: APR not found. Please read the documentation. Google之后，发现可能是gcc版本太低了，可能是apache版本太高，换低点的2.2.23版本吧。 wget http://archive.apache.org/dist/httpd/httpd-2.2.23.tar.gz tar -xvf httpd-2.2.23.tar.gz cd httpd-2.2.23 ./configure --prefix=/usr/local/apache2 make && make install
(2) 安装php版本
wget http://cn2.php.net/distributions/php-5.4.26.tar.gz
tar -xvf php-5.4.26.tar.gz
cd php-5.4.26
./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs
有报错信息：

需要重新安装lib包
yum install libxml2 –y
yum install libxml2-devel –y
之后继续make，成功了：
Make && make install

(3) 配置apache
Apache的配置文件在 /usr/local/apache2/conf/httpd.conf ，vim打开
将
User daemon
Group daemon
修改成：
User nagios
Group nagios
将
<IfModule dir_module>
DirectoryIndex index.html
</IfModule>
修改成：
<IfModule dir_module>
DirectoryIndex index.html index.php
AddType application/x-httpd-php .php
</IfModule>
为了安全起见：nagios的web监控页面需要经过授权才能访问，这需要增加验证配置，即在httpd.conf 文件最后添加如下信息：
#setting for nagios
ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
<Directory "/usr/local/nagios/sbin">
AuthType Basic
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthUserFile /usr/local/nagios/etc/htpasswd //用于此目录访问身份验证的文件
Require valid-user
</Directory>
Alias /nagios "/usr/local/nagios/share"
<Directory "/usr/local/nagios/share">
AuthType Basic
Options None
AllowOverride None
Order allow,deny
Allow from all
AuthName "nagios Access"
AuthUserFile /usr/local/nagios/etc/htpasswd
Require valid-user
</Directory>
(4) 创建apache目录验证文件
在上面的配置中，指定了目录验证文件htpasswd，下面要创建这个文件：
/usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd david
[root@cache-2 php-5.4.26]# /usr/local/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd david
New password:
Re-type new password:
Adding password for user david
查看认证文件的内容：
[root@cache-2 php-5.4.26]# cat /usr/local/nagios/etc/htpasswd
david:$apr1$Pf9XIJjd$m5hR2vw70MlqwrChgN7zc/
[root@cache-2 php-5.4.26]#
启动apache服务：
/usr/local/apache2/bin/apachectl start
[root@cache-2 php-5.4.26]# /usr/local/apache2/bin/apachectl start
httpd: Could not reliably determine the server‘s fully qualified domain name, using 10.254.3.41 for ServerName

修改ServerName以及Port
vi /usr/local/apache2/conf/httpd.conf
ServerName 改成 10.xx.3.x1
Listen 80 改成 Listen 81
http://10.xx.3.x1:81/nagios/，可以打开了，如下所示：
