Nagios安装流程(centos 5.5环境 + nagios-cn-3.2.3.tar.bz2 + )
1、 更新yum源
2、 安装组件
[root@localhost ~]# yum -y install httpd gettext mysql mysql-server mysql-devel php php-mysql php-pear
[root@localhost ~]# yum -y install gd gd-devel php-gd
安装nagios时需要加--with-gd-lib=/usr/lib --with-gd-inc=/usr/include
不然不能生成statusmap.cgi 也就不能看状态图了!
3、 增加帐号
[root@localhost nagios-cn-3.2.3]# useradd nagios
[root@localhost nagios-cn-3.2.3]# passwd nagios
nagios
[root@localhost nagios-cn-3.2.3]# usermod -s /sbin/nologin nagios
[root@localhost nagios-cn-3.2.3]# groupadd nagcmd
[root@localhost nagios-cn-3.2.3]# usermod -G nagcmd nagios
[root@localhost nagios-cn-3.2.3]# usermod -G nagcmd apache
4、 解压nagios-cn文件
[root@localhost nagios-cn-3.2.3]# tar -jxvf nagios-cn-3.2.3.tar.bz2
5、 进入解压文件夹
[root@localhost nagios-cn-3.2.3]#cd nagios-cn-3.2.3
6、 运行安装命令
./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios --with-command-group=nagcmd --with-gd-lib=/usr/lib --with-gd-inc=/usr/include
备注:提示错误
解决办法:因为是centos linux,默认可以采用yum方式安装,则采用如下命令安装gcc编译器即可:# yum -y install gcc
7、 再次运行安装命令(第6步命令),提示没有错误后运行make all 命令然后依次执行下面的命令
[root@localhost nagios-cn-3.2.3]#make all install
[root@localhost nagios-cn-3.2.3]#make install-init //安装启动脚本到/etc/init.d
[root@localhost nagios-cn-3.2.3]#make install-commandmode
[root@localhost nagios-cn-3.2.3]#make install-config //安装初始配置文件到/usr/local/nagios
8、 退出nagios文件夹并解压nagios-plugins并进入
[root@localhost nagios-cn-3.2.3]#cd ..
[root@localhost nagios-cn-3.2.3]# tar -zxvf nagios-plugins-1.4.15.tar.gz
[root@localhost nagios-cn-3.2.3]#cd nagios-plugins-1.4.15
9、 执行安装命令
[root@localhost nagios-plugins-1.4.15]#./configure --prefix=/usr/local/nagios-plugins --with-nagios-user=nagios --with-nagios-group=nagios
10、 然后执行以下命令
[root@localhost nagios-plugins-1.4.15]# make
[root@localhost nagios-plugins-1.4.15]# make install
11、 安装完成以后在/usr/local/nagios-plugins 会产生一个 libexec 的目录,将该目录全部移动到/usr/local/nagios目录下即可。
[root@localhost nagios-plugins-1.4.15]#mv /usr/local/nagios-plugins/libexec /usr/local/nagios/
12、 配置Apache:在apache的httpd.conf 文件中加入如下内容:
[root@localhost /]# vi /etc/httpd/conf/httpd.conf
###nagios
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>
13、 启动Apache服务
[root@localhost /]# service httpd restart
14、 设置报报警邮箱
[root@localhost /]# vi /usr/local/nagios/etc/objects/contacts.cfg
将nagios@localhost改为自己的邮箱(310475629@qq.com),保存并退出。
15、 设置登陆web密码
[root@localhost /]# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
New password: (nagiosadmin)
Re-type new password: (nagiosadmin)
Adding password for user nagiosadmin
16、 启动(重启)相关服务(Apache及nagios服务)
[root@localhost /]# service httpd restart
[root@localhost /]# service nagios restart
17、 检查配置文件是否正确
如果出现如下显示就说明配置没问题
Total Warnings: 0
Total Errors: 0
18、 现在就可以http://你的 IP/nagios/访问 nagios(实验IP地址为192.168.1.8),提示正常的界面则nagios安装成功。
