一、配置安装环境 yum install httpd*
yum install php*
yum install net-snmp
yum install mysql*
yum install glibc*
二、安装nagios
2.1 增加用户及创建目录
groupadd nagios
useradd -g nagios nagios
usermod -G nagios apache //将apache、nagios用户加入到nagios组里；
usermod -G nagios nagios
mkdir /usr/local/nagios
chown -R nagios:nagios /usr/local/nagios
2.2 安装nagios主程序
在 /usr/local/目录下建立一个软件存放目录soft
mkdir soft
将主程序拷备到soft目录中 [./为当前目录]
cd soft
cp /root/shared/nagios-3.5.0.tar.gz ./
解压缩
tar -zxvf nagios-3.5.0.tar.gz
cd nagios
编译,指定安装目录为/usr/local/nagios
./configure --prefix=/usr/local/nagios
#注意横线前后都是没有空格的，不然会有问题
make all
make install
make install-init
make install-config
make install-commandmode
make install-webconf
进入到/usr/local/nagios下查看是否有etc、bin、 sbin、 share、 var这五个目录
2.3 安装插件
cd /usr/local/soft/
cp /root/shared/nagios-plugins-1.4.16.tar.gz ./
tar -zxvf nagios-plugins-1.4.16.tar.gz
cd nagios-plugins-1.4.16
./configure --prefix=/usr/local/nagios/
make
make install
2.4 修改apache配置文件进行登录验证
增加登录认证用户及密码配置
/usr/bin/htpasswd -c /usr/local/nagios/etc/htpasswd.users admin（nagiosadmin为账号）
在配置文件中加入以下选项(也可以不加)
vim /etc/httpd/conf/httpd.conf
ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"
<Directory "/usr/local/nagios/sbin">
# SSLRequireSSL
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
# Order deny,allow
# Deny from all
# Allow from 127.0.0.1
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</Directory>
Alias /nagios "/usr/local/nagios/share"
<Directory "/usr/local/nagios/share">
# SSLRequireSSL
Options None
AllowOverride None
Order allow,deny
Allow from all
# Order deny,allow
# Deny from all
# Allow from 127.0.0.1
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</Directory>
2.5 配置各服务开机启动
#配置机器启动时自动启动Nagios
chkconfig --add nagios
chkconfig nagios on
chkconfig --add httpd
chkconfig httpd on
chkconfig --list httpd
chkconfig --add mysqld
chkconfig mysqld on
chkconfig --list mysqld
2.6 关闭SELinux
vi /etc/selinux/config
SELINUX=disabled
2.7 检查Nagios配置文件
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
2.8 安装nrpe插件
cd /usr/local/soft/
cp /root/shared/nrpe-2.13.tar.gz ./
tar -zxvf nrpe-2.13.tar.gz
cd nrpe-2.13
./configure
make all
make install-plugin
make install-daemon
make install-daemon-config
/usr/bin/install -c -m 775 -o nagios -g nagios -d /usr/local/nagios/etc
/usr/bin/install -c -m 644 -o nagios -g nagios sample-config/nrpe.cfg /usr/local/nagios/etc
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
通过如下命令验证nrpe是否正常，可以看到端口5666已经打开
/usr/local/nagios/libexec/check_nrpe -H localhost
netstat -atulnp | grep 'nrpe'
三、安装nagiosql
3.1 安装前准备
NagiosQL的本身其实就是一个web程序，安装过程很简单，就是在Webserver下部署
- Webserver e.g. Apache 1.x or above 使用apache2.x
- PHP 4.3 or above PHP4.3或以上版本
- MySQL 4.1 or above MySQL4.1或以上版本
- Nagios 2 or above Nagios2或以上版本，使用3.x
- PEAR Module: HTML_Template_IT 1.1 or above（输入rpm -qa php-pear查看是否安装）
以下环境配置查看用：php -m 命令查看
- PHP Extension: gettext
- PHP Extension: mysql （没有安装则输入 yum install php-mysql 进行安装）
- PHP Extension: ftp
3.1.1 安装PEAR Module: HTML_Template_IT 1.1
安装以下项目前，请确保安装 php-pear 安装命令yum install php-pear
通过pear install HTML_Template_IT 命令进行安装
如果出现无法找到HTML_Template_IT包的现象
到PEAR 官网下载最新的HTML_Template_IT包 http://pear.php.net/package/PEAR 放到如下目录：/usr/share/pear/PEAR/PackageFile/
cp /root/shared/HTML_Template_IT-1.3.0.gz /usr/share/pear/PEAR/PackageFile/
再次运行以下命令 安装成功
pear install HTML_Template_IT-1.3.0.gz
3.1.2 安装php 的 SSH2扩展
1.用rpm -qa openssl 、rpm -qa openssl-devel命令 查看是否安装openssl openssl-devel 两个
2.编译安装libssh2
cd /usr/local/soft/
wget http://www.libssh2.org/download/libssh2-1.2.9.tar.gz
tar zxvf libssh2-1.2.9.tar.gz
cd libssh2-1.2.9
./configure
make
make install
3.编译安装ssh2(官网http://www.php.net/ssh2)
安装前请确保安装php-devel
cd /usr/local/soft/
wget http://pecl.php.net/get/ssh2-0.11.2.tgz
tar zxvf ssh2-0.11.2.tgz
cd ssh2-0.11.2
phpize（如果没有找到该命令，请确定是否安装的是php-devel）
./configure --with-ssh2
make
cp modules/ssh2.so /usr/lib/php/modules/
echo "extension=ssh2.so" >> /etc/php.ini
4.重启php
service httpd restart
3.1.3 修改php时差及标准时间
php5默认date.timezone为utc，改为date.timezone = PRC
vim /etc/php.ini
找到date.timezone 将值修改为PRC 并去掉;号
重启php service httpd restart
3.2 安装nagiosql 主程序
3.2.1 相关环境
Nagios根位置：/usr/local/nagios
Nagios配置文件位置：/usr/local/nagios/etc
Nagios的用户和用户组：nagios|nagios
apache的启动用户和用户组:apache|apache
设置mysql root账号的密码 命令如下：
mysqladmin -u root password 'systemg'
3.2.2 安装主程序
解压nagiosql_320.tar.gz到/usr/local/nagios/nagiosql下
cd /usr/local/nagios/
cp /root/shared/nagiosql_320.tar.gz ./
tar -zxvf nagiosql_320.tar.gz
mv nagiosql32 nagiosql
修改用户权限
chown -R nagios:nagios /usr/local/nagios/nagiosql
chmod 777 /usr/local/nagios/nagiosql
修改config目录的访问权限，以使apache对其具有写权限，、
chmod -R 777 /usr/local/nagios/nagiosql/config
创建配置文件目录，并修改权限
cd /usr/local/nagios/nagiosql/
mkdir etc
cd etc
mkdir backup hosts import services
cd backup
mkdir hosts services
对nagiosql下的etc进行权限设置
chown -R apache:apache etc
在install下创建ENABLE_INSTALLER文件
cd /usr/local/nagios/nagiosql/install
touch ./ENABLE_INSTALLER
修改apache的httpd.conf文件，部署web服务，添加如下内容。
apache配置文件位置vim /etc/httpd/conf/httpd.conf
Alias /nagiosQL "/usr/local/nagios/nagiosql"
<Directory "/usr/local/nagios/nagiosql">
# SSLRequireSSL
Options None
AllowOverride None
Order allow,deny
Allow from all
</Directory>
重启php service httpd restart
通过IE浏览器进入如下地址http://<IP>/ nagiosQL，其中IP是apache服务主机的IP地址
3.2.3 修改基本系统配置：
【管理】-【Config targets】-【修改】
如下：
【基目录】/usr/local/nagios/nagiosql/
【主机目录】/usr/local/nagios/nagiosql/etc/hosts/
【服务目录】/usr/local/nagios/nagiosql/etc/services/
【备份目录】/usr/local/nagios/nagiosql/etc/backup/
【主机备份目录】/usr/local/nagios/nagiosql/etc/backup/hosts/
【服务备份目录】/usr/local/nagios/nagiosql/etc/backup/services/
【Nagios基目录】/usr/local/nagios/etc/
【导入路径】/usr/local/nagios/etc/objects/
【Nagios命令文件】/usr/local/nagios/var/rw/nagios.cmd
【Nagios执行文件】/usr/local/nagios/bin/nagios
【Nagios进程文件】/usr/local/nagios/var/nagios.lock
【Nagios配置文件 】/usr/local/nagios/etc/nagios.cfg
3.2.4 导入nagios配置到Nagiosql里
点击工具→导入数据→按住ctrl，选择以下组件，然后点击导入
commands.cfg
contacts.cfg
templates.cfg
timeperiods.cfg
3.2.5 更改Nagiosql的权限
chown -R nagios.nagios /usr/local/nagios/nagiosql/
chmod -R 777 /usr/local/nagios/nagiosql/
3.2.6 写入配置文件
3.2.6.1 写入检测数据
根据所导入的数据生成hosts、hostgroup、services、servicegroup之类文件，点击工具→Nagios控制→写入检测数据→提交
此时会在/usr/local/nagios/nagiosql/下生成如下文件
hostgroups.cfg
hosttemplates.cfg
servicegroups.cfg
servicetemplates.cfg
在/usr/local/nagios/nagiosql/etc/hosts/目录生成对应已有主机台数数量的主机配置文件
在/usr/local/nagios/nagiosql/etc/services/目录中生成services的文件
3.2.6.2 写入其他数据
根据所导入的数据生成command、timeperiods.cfg、contacts.cfg 等文件，点击工具→Nagios控制→写入其他数据→提交
此时会在/usr/local/nagios/nagiosql/目录中生成如下文件
commands.cfg
contacts.cfg
timeperiods.cfg
servicetemplates.cfg
3.2.7 关闭nagios配置文件，应用Nagiosql配置文件
#cfg_file=/usr/local/nagios/etc/objects/commands.cfg
#cfg_file=/usr/local/nagios/etc/objects/contacts.cfg
#cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg
#cfg_file=/usr/local/nagios/etc/objects/templates.cfg
以下项打开，没有的添加
cfg_file=/usr/local/nagios/nagiosql/commands.cfg
cfg_file=/usr/local/nagios/nagiosql/contactgroups.cfg
cfg_file=/usr/local/nagios/nagiosql/contacts.cfg
cfg_file=/usr/local/nagios/nagiosql/contacttemplates.cfg
cfg_file=/usr/local/nagios/nagiosql/hostdependencies.cfg
cfg_file=/usr/local/nagios/nagiosql/hostescalations.cfg
cfg_file=/usr/local/nagios/nagiosql/hostextinfo.cfg
cfg_file=/usr/local/nagios/nagiosql/hostgroups.cfg
cfg_file=/usr/local/nagios/nagiosql/hosttemplates.cfg
cfg_file=/usr/local/nagios/nagiosql/servicedependencies.cfg
cfg_file=/usr/local/nagios/nagiosql/serviceescalations.cfg
cfg_file=/usr/local/nagios/nagiosql/serviceextinfo.cfg
cfg_file=/usr/local/nagios/nagiosql/servicegroups.cfg
cfg_file=/usr/local/nagios/nagiosql/servicetemplates.cfg
cfg_file=/usr/local/nagios/nagiosql/timeperiods.cfg
cfg_dir=/usr/local/nagios/nagiosql/etc/hosts/
cfg_dir=/usr/local/nagios/nagiosql/etc/services/
3.2.8 登录Nagiosql界面，添加主机和服务器
完成安装
