Nagiosserver端安装部署具体解释(1)
下载地址例如以下： http://sourceforge.net/projects/nagios/files/
具体具体下载地址：http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-4.0.6.tar.gz1 開始下载：
wget http://sourceforge.net/projects/nagios/files/nagios-4.x/nagios-4.0.6/nagios-4.0.6.tar.gz/download?use_mirror=jaist
例如以下图所看到的，下载free版本号的。
?
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 ##假设SELinux status參数为enabled即为开启状态
SELinux status: enabled
(2)getenforce ##也能够用这个命令检查
关闭SELinux：
(3)暂时关闭（不用重新启动机器）：
setenforce 0 ##设置SELinux 成为permissive模式
##setenforce 1 设置SELinux 成为enforcing模式
(4)改动配置文件须要重新启动机器：
改动/etc/selinux/config 文件
将SELINUX=enforcing改为SELINUX=disabled
重新启动机器就可以
3 開始准备nagios安装环境
(1) 加入?nagios运行所须要的用户和组：
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 開始make安装
5.1 make all
[root@cache-2 nagios-4.0.6]# make all
cd ./base && make

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：
切换文件夹到安装路径（这里是/usr/local/nagios），看是否存在etc、bin、sbin、share、var 这五个文件夹，假设存在则能够表明程序被正确的安装到系统了。Nagios 各个文件夹用途说明例如以下：
bin Nagios 可运行程序所在文件夹
etc Nagios 配置文件所在文件夹
sbin Nagios CGI 文件所在文件夹，也就是运行外部命令所需文件所在的文件夹
share Nagios网页文件所在的文件夹
libexec Nagios 外部插件所在文件夹
var Nagios 日志文件、lock 等文件所在的文件夹
var/archives Nagios 日志自己主动归档文件夹
var/rw 用来存放外部命令文件的文件夹
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])
開始安装：
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版本号太低了，可能是apache版本号太高，换低点的2.2.23版本号吧。 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版本号
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：
Configuring extensions

须要又一次安装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
改动成：
User nagios
Group nagios
将
<IfModule dir_module>
DirectoryIndex index.html
</IfModule>
改动成：
<IfModule dir_module>
DirectoryIndex index.html index.php
AddType application/x-httpd-php .php
</IfModule>
为了安全起见：nagios的web监控页面须要经过授权才干訪问，这须要添加?验证配置，即在httpd.conf 文件最后加入?例如以下信息：
#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 //用于此文件夹訪问身份验证的文件
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文件夹验证文件
在上面的配置中，指定了文件夹验证文件htpasswd，以下要创建这个文件：
/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
(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
改动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/，能够打开了，例如以下所看到的：
