简介
icinga是nagios的二次开发包,说是原来的团队觉得nagios进展太慢了,然后跳出来开展了这个项目。ICINGA-CN说明如下:
ICINGA项目是由Michael Luebben、HendrikB?cker和JoergLinge等人发起的,他们都是现有的Nagios项目社区委员会的成员,他们承诺,新的开源项 目将完全兼容以前的Nagios应用程序及扩展功能。在新项目的网站上,他们是如此定义ICINGA的,这将是一个介于Nagios社区版和企业版间的产
品。特别将致力于解决Nagios项目现在的问题,比如不能及时处理Nagios项目的bug、新功能不能及时添加等。还有在新的ICINGA项目中,将 更好的实现数据库集成方面的功能,标准化第三发应用程序的接口等。中文化项目是由Icinga中文化项目组,基于icinga(http://www.icinga.com)基础上,并在此基础上针对中文需求进行优化及修改,同时集成nagiosgraph或pnp4nagios绘图,包括简体中文、繁体中文(计划),界面以及生成的图像都已中文化。
安装准备
安装以centos6.4为例,#> yum install httpd gcc glibc glibc-common gd gd-devel #> yum install libjpeg libjpeg-devel libpng libpng-devel
yum install mysql mysql-server \ libdbi libdbi-devel libdbi-drivers libdbi-dbd-mysql
下载最新版的icinga
http://sourceforge.net/projects/icinga-cn/files/icinga-cn/备用:http://dl.vmall.com/c09kipj6x2
最新版是1.9,得到 icinga-cn-1.9.3.tar.bz2
添加用户,
useradd -m icinga修改密码
#> passwd icinga
编译和安装Icinga(包括IDOUtils)
tar xvf icinga-cn-1.9.3.tar.bz2 cd icinga-cn-1.9.3 ./configure
输出如下,
Creating sample config files in sample-config/ ... Creating sample config files in module/idoutils/config/ ... readline() on closed filehandle IN at subst line 22. *** Configuration summary for icinga-core 1.9.3 07-07-2013 ***: General Options: ------------------------- Icinga executable: icinga Icinga user/group: icinga,icinga Command user/group: icinga,icinga Apache user/group: apache,apache Embedded Perl: no Event Broker: yes ido2db lockfile: ${prefix}/var/ido2db.lock ido sockfile: ${prefix}/var/ido.sock idomod tempfile: ${prefix}/var/idomod.tmp Build IDOUtils: libdbi, instance_name=default libdbi driver dir: /usr/local/lib/dbd Install ${prefix}: /usr/local/icinga Lock file: ${prefix}/var/icinga.lock Temp file: /tmp/icinga.tmp Chk file: ${prefix}/var/icinga.chk HTTP auth file: ${prefix}/etc/htpasswd.users Lib directory: ${exec_prefix}/lib Bin directory: ${exec_prefix}/bin Plugin directory: ${exec_prefix}/libexec Eventhandler directory: ${exec_prefix}/libexec/eventhandlers Log directory: ${prefix}/var Check result directory: ${prefix}/var/spool/checkresults Temp directory: /tmp State directory: ${prefix}/var Ext Cmd file directory: ${prefix}/var/rw Init directory: /etc/rc.d/init.d Apache conf.d directory: /etc/httpd/conf.d Apache config file: /etc/httpd/conf.d/icinga.conf Mail program: /bin/mail Host OS: linux-gnu Environment Prefix: ICINGA_ Web Interface Options: ------------------------ HTML URL: http://localhost/icinga/ CGI URL: http://localhost/icinga/cgi-bin/ Main URL: http://localhost/icinga/cgi-bin/tac.cgi Review the options above for accuracy. If they look okay, type 'make all' to compile the main program and CGIs.确认无误后,输入
make all输出如下:
*** Compile finished *** If the main program and CGIs compiled without any errors, you can continue with installing Icinga as follows (type 'make' without any arguments for a list of all possible options): make install - This installs the main program (Icinga Core), CGIs (Classical Web), and HTML files make install-init - This installs the init script in /etc/rc.d/init.d make install-commandmode - This installs and configures permissions on the directory for holding the external command file make install-idoutils - This installs the database addon IDOUtils into the destination directory make install-config - This installs *SAMPLE* config files in /usr/local/icinga/etc You'll have to modify these sample files before you can use Icinga. Read the HTML documentation for more info on doing this. Pay particular attention to the docs on object configuration files, as they determine what/how things get monitored! make install-webconf - This installs the Apache config file and http auth file for the Icinga Classic UI *** Support Notes ******************************************* If you have questions about configuring or running Icinga, please make sure that you: - Look at the sample config files - Read the HTML documentation in html/docs/ before you post a question to one of the mailing lists at http://www.icinga.org/support/ or at Icinga Portal: http://www.icinga-portal.org执行:
#> make install #> make install-init #> make install-config #> make install-eventhandlers #> make install-commandmode #> make install-idoutils
配置
如果您的数据库没有位于本机,您需要更改ido2db.cfg:socket_type=tcp
启用idomod event broker 模块
cd /usr/local/icinga/etc/ mv modules/idoutils.cfg-sample modules/idoutils.cfg
数据库创建和IDOUtils
#> mysql -u root -p mysql> CREATE DATABASE icinga; GRANT USAGE ON icinga.* TO 'icinga'@'localhost' IDENTIFIED BY 'icinga' WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0; GRANT SELECT, INSERT, UPDATE, DELETE, DROP, CREATE VIEW, INDEX, EXECUTE ON icinga.* TO 'icinga'@'localhost'; FLUSH PRIVILEGES; quit导入数据库结构:
回到解压好的安装包目录
mysql -u root -p icinga < ./module/idoutils/db/mysql/mysql.sql登录mysql看一下dbversion
mysql> select * from icinga_dbversion; +--------------+----------+---------+---------------------+---------------------+ | dbversion_id | name | version | create_time | modify_time | +--------------+----------+---------+---------------------+---------------------+ | 1 | idoutils | 1.9.0 | 2013-11-07 13:52:33 | 2013-11-07 13:52:33 | +--------------+----------+---------+---------------------+---------------------+1.9.0,不用更新,如果需要更新
mysql -u root -p icinga < ./module/idoutils/db/mysql/upgrade/mysql-upgrade-1.9.0.sql
编辑DB配置文件自定义IDOUtils
vim /usr/local/icinga/etc/ido2db.cfg
db_servertype=mysql db_port=3306 db_user=icinga db_pass=icinga默认就是这个用户名和密码
配置经典的Web界面,安装Icinga附带的经典web界面("CGIs")
#> make cgis #> make install-cgis #> make install-html安装经典web配置文件到Apache的conf.d目录下.
#> make install-webconf创建 icingaadmin 账户,登录到Icinga经典web界面.
记住您分配给这个帐户的密码 -稍后你会需要它.
#> htpasswd -c /usr/local/icinga/etc/htpasswd.users icingaadmin如果你想改变用户密码,或添加另一个用户,请使用以下命令:
#> htpasswd /usr/local/icinga/etc/htpasswd.users <USERNAME>
启动icinga和ido2db
service ido2db start service icinga start配置开机启动
chkconfig ido2db on
chkconfig icinga on
登录:
http://yourdomain.com/icinga/
发现错误:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
查日志发现:
(13)Permission denied: exec of '/usr/local/icinga/sbin/tac.cgi' failed
关闭selinux
setenforce 0
重启httpd
上次监控是红色的,联不通,因为还没有安装用于监控的插件
安装插件:
http://sourceforge.net/projects/icinga-cn/files/icinga%20plugins/下载nagios-cn-plugins-1.5.tar.bz2
tar xvf nagios-cn-plugins-1.5.tar.bz2 cd nagios-cn-plugins-1.5 ./configure --prefix=/usr/local/icinga --with-package-name=icinga-plugins --with-cgiurl=/icinga/cgi-bin #> make #> make install
此步骤有时候会报错,建议下载icinga-cn-plugins-1.4.16.tar.bz2
如果下载的是icinga-cn-plugins-1.4.16.tar.bz2可直接不加参数
./configure #> make #> make install安装check_nrpe 插件
下载icinga-nrpe-2.14.tar.gz
tar xvf icinga-nrpe-2.14.tar.gz cd icinga-nrpe-2.14 ./configure报错:
configure: error: Cannot find ssl headers
安装ssl
yum install openssl openssl-devel.x86_64
重新configure,结果如下
*** Configuration summary for nrpe 2.14 12-21-2012 ***: General Options: ------------------------- NRPE port: 5666 NRPE user: icinga NRPE group: icinga Icinga user: icinga Icinga group: icinga Review the options above for accuracy. If they look okay, type 'make all' to compile the NRPE daemon and client.make安装即可,make all后结果
*** Compile finished *** make install - This installs files in /usr/local/icinga make install-plugin - This installs init-script files in /usr/local/icinga/libexec make install-init - This installs init-script files in /etc/init.d make install-xinetd - This installs sample-config/nrpe.xinetd in /etc/xinit.d make install-init-freebsd - This installs init-script.freebsd files in /etc/init.d make install-init-debian - This installs init-script.debian files in /etc/init.d make install-init-suse - This installs init-script.suse files in /etc/init.d make install-daemon-config - This installs the Nrpe config file in /usr/local/icinga/etc安装即可
#> make all
#> make install-plugin
重新启动icinga ido2db服务,再次登录查看即可。
如果希望能够通过nrpe来监控服务端本机,可以安装nrpe的daemon
#> make install #> make install-plugin #> make install-daemon #> make install-daemon-config #> make install-init配置文件地址:/usr/local/icinga/etc/nrpe.cfg
注意:allowed_hosts=127.0.0.1 可以多加一些,用逗号分割
按照实际环境 取消下面
command[check_users]= 等列,配置好参数,
command[check_users]=/usr/local/icinga/libexec/check_users -w 5 -c 10 command[check_load]=/usr/local/icinga/libexec/check_load -w 15,10,5 -c 30,25,20 command[check_hda1]=/usr/local/icinga/libexec/check_disk -w 20% -c 10% -p /dev/hda1 command[check_zombie_procs]=/usr/local/icinga/libexec/check_procs -w 5 -c 10 -s Z command[check_total_procs]=/usr/local/icinga/libexec/check_procs -w 150 -c 200 command[check_ssh]=/usr/local/icinga/libexec/check_ssh -H localhost command[check_swap]=/usr/local/icinga/libexec/check_swap -w 20% -c 10% command[check_mysql]=/usr/local/icinga/libexec/check_mysql -H localhost -uroot -ptomcat2008 command[check_apache]=/usr/local/icinga/libexec/check_apachestatus -H localhost -p 80 command[check_ntp]=/usr/local/icinga/libexec/check_ntp -H localhost -w 0.5 -c 1 command[check_snmp]=/usr/local/icinga/libexec/check_snmp_service -H localhost -C monitor_energysh启动服务
service icinga-nrpe start
测试nrpe是否安装成功
/usr/local/icinga/libexec/check_nrpe -H 127.0.0.1
