容量规划中的工具

简单记录使用的工具,对于使用哪个工具的批判标准是:
只要符合你的某个程度上的需要,就是说只要满足你需要的批判标准,获取到对应的数据,就不必再纠结于使用什么样的工具了.

Cacti
sudo apt-get install cacti
中间会下载mysql,tomcat,apache等辅助的软件,下吧.不过貌似这些工具都是这样的.
cacti使用的画图工具时rrdtools.

安装过程中会让你输入mysql数据库中的root的密码,还会让你输入administrator的密码等.设置的合理一点是常用的密码****gamma.

最后是:
http://10.13.8.27/cacti

可以通过这个地址访问对应的cacti安装程序,这个是一个apache的内容.
查看监听的地址:

hibernatesone@hibernatesone-laptop:/etc/apache2/conf.d$

80的是一个apache的启动内容,而8080是一个tomcat的启动程序.

再看看apache的启动内容:
hibernatesone@hibernatesone-laptop:/etc/apache2/conf.d$ ps -aef | grep apache
tomcat6    937     1  0 19:22 ?        00:00:05 /usr/lib/jvm/java-6-openjdk/bin/java -Djava.util.logging.config.file=/var/lib/tomcat6/conf/logging.properties -Djava.awt.headless=true -Xmx128M -XX:+UseConcMarkSweepGC -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/usr/share/tomcat6/endorsed -classpath /usr/share/tomcat6/bin/bootstrap.jar -Dcatalina.base=/var/lib/tomcat6 -Dcatalina.home=/usr/share/tomcat6 -Djava.io.tmpdir=/tmp/tomcat6-tmp org.apache.catalina.startup.Bootstrap start

其中一个是tomcat6的,另一个是apache2的.

hibernatesone@hibernatesone-laptop:/etc/apache2$ whereis apache2
apache2: /usr/sbin/apache2 /etc/apache2 /usr/lib/apache2 /usr/share/apache2 /usr/share/man/man8/apache2.8.gz
apache2的配置文件一般在/etc/apache2中.
进入详细的看看.

发现还有一个conf.d目录,其中内容如下:
/etc/apache2/conf.d

hibernatesone@hibernatesone-laptop:/etc/apache2$ ls conf.d/
cacti.conf  charset  localized-error-pages  security

发现了cacti.conf文件内容了...

Alias /cacti /usr/share/cacti/site


        Options +FollowSymLinks
        AllowOverride None
        order allow,deny
        allow from all

        AddType application/x-httpd-php .php

        php_flag magic_quotes_gpc Off
        php_flag short_open_tag On
        php_flag register_globals Off
        php_flag register_argc_argv On
        php_flag track_vars On
        # this setting is necessary for some locales
        php_value mbstring.func_overload 0
        php_value include_path .

        DirectoryIndex index.php


cacti的内容配置是:
Alias /cacti /usr/share/cacti/site
这个说明了为什么能够使用上面的url进行访问了,这里定义了apache的/cacti 的别名.OK.

看看site中的内容:

hibernatesone@hibernatesone-laptop:/usr/share/cacti/site$ ls
about.php                data_queries.php    graph_settings.php          graph_view.php      install              rra.php               user_admin.php
auth_changepassword.php  data_sources.php    graphs_items.php            graph_xport.php     lib                  scripts               utilities.php
auth_login.php           data_templates.php  graphs_new.php              host.php            logout.php           script_server.php
cdef.php                 docs                graphs.php                  host_templates.php  poller_commands.php  settings.php
cmd.php                  gprint_presets.php  graph_templates_inputs.php  images              poller_export.php    templates_export.php
color.php                graph_image.php     graph_templates_items.php   include             poller.php           templates_import.php
data_input.php           graph.php           graph_templates.php         index.php           resource             tree.php

基本上就确认了cacti是用的内容了.

看看cacti中阐述的:
Cacti requires MySQL, PHP, RRDTool, net-snmp, and a webserver that supports PHP such as Apache or IIS. Please see the requirements section of the manual for information on how to fulfill these requirements under certain operating systems. Please use the install guide for either Unix or Windows for information about installing Cacti.

对于tomcat6,先不用管它....apt-get install也是一个不爽的事情,动不动就给你启动...一时还没去想好方法...

使用http://10.13.8.27/cacti能够直接定位到install步骤,会让你输入一些密码的,简单的来,以后可以修改的....
cacti的默认登录账号是:
admin
admin

千万别设置的连你自己都会忘记的密码.

好了.
http://10.13.8.27/cacti/index.php

已经能够访问了...
