一、centreon批量添加主机

本部分参考了同事的文档和链接：http://blog.chinaunix.net/uid-17196076-id-2817703.html

 

centreon的模板功能是做的非常强大的，而且优化过的nagios配置十分简单，加host的时候只需要输入了hostname，alias和ip 地址就可以加一台host上去，service配在hostgroup上，这样只要把host添加到hostgroup上就可以了。

   如果你要加一两台机器，那是很方便的，但是如果上百台呢，上千台呢？那手岂不是要点的抽筋了？

   这点来看，还是用脚本批量添加来的方便，呵呵，共享一个自己写的批量添加host的脚本，只添加host，service和hostgroup自己配。
  
   运行脚本之前，要先准备好几件事情：
   1、要有一个host的模板，将所有的属性基本上定义完整，使用脚本添加的host会和模板一模一样，只有ip地址和hostname有差别
   2、要确认了host要添加到哪台nagios上，在centreon里叫poller
   3、要有一个hosts文件，里面内容为要批量添加的hostname和ip地址，类似/etc/hosts的格式，第一栏ip，第二栏hostname

   脚本用perl写的，最前面db的部分需要修改，代码如下：
#!/usr/bin/perl

# File name: insert_host.pl
# Use: insert host into centreon database

# ----------------------------------------------------

my $DB_USER = "db_user";             # web安装时设置的数据库访问用户，修改为centreon
my $DB_PASSWD = "db_password";     # web安装时设置的数据库密码，修改为centreon
my $DB_NAME = "centreon";                   # web安装时设置的数据库名，默认也是centreon
my $dbh = DBI->connect("DBI:mysql:database=$DB_NAME;host=$DB_HOST",
                       "$DB_USER", "$DB_PASSWD", { RaiseError => 1 });

# ----------------------------------------------------
my $file_path = "./hosts";       #hosts文件，自己创建
my $tpl_name = "generic-host";     #主机模板，填写你需要继承的模板；
my $nagios_name = "nagios_name";     #poller，修改为Central

    # == file of hostname and ipaddress ==
    if ($arg eq '-f') {

        }

        $tpl_name = shift;
        }

        $nagios_name = shift;
        }

    else {
        &print_help();
        exit 1;
        }
    }

open (HOST, "$file_path") || die "Cannot open $file_path for read";

my $sql;
my $sth;
my $line;
my ($host, $ipaddr);
my ($host_id, $tpl_id, $nagios_id) = (0, 0, 0);

while (defined($line = <HOST>)) {

    # == skip blank lines =================

演示：

上面的脚本名我换成了add_host.pl，并创建hosts文件：

二、批量生成和主机相关联的服务

注：此部分引用了同事的文档和脚本~

 

上面的脚本能够批量添加主机，但是不能自动生成和主机相关联的服务，如果对每一台主机增加一个服务，要一个一个在页面点击，非常麻烦。

 

使用 Centreon CLAPI  可以解决这个问题，Centreon CLAPI 是centreon 命令行接口，可以替代在网页上的许多工作，这里我们只介绍下怎么解决我们的问题。了解更多请看网址：

http://forge.centreon.com/projects/centreon-clapi/wiki

 

安装clapi：

[root@centreon ~]# cd /usr/local/src/

[root@centreon src]# tar zxf centreon-clapi-1.1.tar.gz

[root@centreon src]# cd centreon-clapi-1.1

[root@centreon centreon-clapi-1.1]# ./install.sh -i

提示输入instCentWeb.conf配置文件的路径：/usr/local/centreon/etc/

 

[root@centreon centreon-clapi-1.1]# cd /usr/local/centreon/www/modules/centreon-clapi/core/

[root@centreon core]# vi +64 centreon

require_once "$centreon_etc/centreon.conf.php";

改为:

require_once "/usr/local/centreon/etc/centreon.conf.php";

 

查看所有主机：

[root@centreon core]# ./centreon -uadmin -p111111 -o HOST -a show

查看主机名包含client-1的主机，如果是输入client，则会显示client,client-1,client-2

[root@centreon core]# ./centreon -uadmin -p111111 -o HOST -a show -v "client-1"

对client主机应用所关联的模板服务：

[root@centreon core]# ./centreon -uadmin -p111111 -o HOST -a applytpl -v "client-1"

执行命令前的服务：

 

执行后client-1服务都已添加：

通过以上命令可以关联模板的服务，如果需要批量添加，只需写个简单的脚本就能实现，见下图，执行前可删除刚才手动执行的命令添加的client服务：

 

WEB刷新服务：

 

批量添加完主机和服务要需要重新生成nagios配置后生效。
