Linux下Cacti安装与配置.doc

Linux下Cacti安装与配置原文链接：/Linux/2011-11/46712.htm这个是linux下安装配置Nagios和Cacti的第一个步骤，即配置一个web的环境，这里采用的是lamp的架构！这里采用的linux平台是RHEL 5.4的版本首先是mysql的编译安装（GCC和MAKE都要安装上，其他的套件按需安装）免费下载地址在 / 用户名与密码都是rootlocalhost httpd# useradd mysqlrootlocalhost # ll mysql-5.1.59.tar.gz -rw-r-r- 1 root root 24325443 Oct 14 22:38 mysql-5.1.59.tar.gzrootlocalhost # tar zxvf mysql-5.1.59.tar.gzrootlocalhost mysql-5.1.59# ./configure -prefix=/usr/local/mysql -enable-local-infile -with-charset=gbk -with-extra-charsets=all -with-low-memory -with-mysqld-user=mysql -enable-thread-safe-clientrootlocalhost mysql-5.1.59#make & make installrootlocalhost mysql-5.1.59# cd /usr/local/mysql/rootlocalhost mysql# chown -R mysql.mysql .rootlocalhost mysql# ./bin/mysql_install_db -user=mysqlrootlocalhost mysql# chown -R root .rootlocalhost mysql# chown -R mysql /var/rootlocalhost mysql# ./bin/mysqld_safe -user=mysql &rootlocalhost mysql# netstat -tulnp|grep 3306tcp00 :330:* LISTEN20438/mysqldrootlocalhost mysql# cd （这部分是制作mysql的开机启动项）rootlocalhost # echo /usr/local/mysql/lib/mysql /etc/ld.so.confrootlocalhost # ldconfig -vrootlocalhost # ln -s /usr/local/mysql/bin/mysql /usr/local/bin/mysqlrootlocalhost # cp mysql-5.1.59/support-files/mysql.server /etc/init.d/mysqldrootlocalhost # chmod 775 /etc/init.d/mysqldrootlocalhost # cp mysql-5.1.59/support-files/f /etc/my-cnfrootlocalhost # chkconfig -add mysqldrootlocalhost # chkconfig mysqld onrootlocalhost # chkconfig -list|grep mysqldmysqld0:off 1:off 2:on3:on4:on5:on6:of接着是apache的编译安装rootlocalhost # ll httpd-2.2.6.tar.gz -rw-r-r- 1 root root 6028951 Sep62007 httpd-2.2.6.tar.gzrootlocalhost # tar zxvf httpd-2.2.6.tar.gz rootlocalhost # cd httpd-2.2.6rootlocalhost httpd-2.2.6# ./configure -prefix=/usr/local/httpd -enable-so-enable-rewrite -enable-ssl -with-ssl=/usr/local/openssl -with-zlib -enable-mods-shared=all -enable-track-vars -with-mysql=/usr/local/mysqlrootlocalhost httpd-2.2.6# make & make installrootlocalhost httpd-2.2.6# echo /usr/local/httpd/bin/apachectl start /etc/rc.local rootlocalhost httpd-2.2.6# /usr/local/httpd/bin/apachectl startrootlocalhost httpd-2.2.6# netstat -tulnp|grep 80tcp00 :80 :*LISTEN19055/httpd接着添加php的支持rootlocalhost # cd /usr/local/httpd/conf/rootlocalhost conf# cp httpd.conf httpd.conf.bak rootlocalhost conf# vi httpd.conf （红色字体为修改部分）DocumentRoot /var/wwwOptions FollowSymLinksAllowOverride NoneOrder deny,allowAllow from allAddType application/x-httpd-php .phpAddType application/x-httpd-php-source .phps最后是php的编译安装rootlocalhost # ll php-5.2.5.tar.gz -rw-r-r- 1 root root 9972372 Jan32008 php-5.2.5.tar.gzrootlocalhost # tar zxvf php-5.2.5.tar.gz rootlocalhost php-5.2.5# ./configure -prefix=/usr/local/php -with-config-file-path=/etc -with-apxs2=/usr/local/httpd/bin/apxs -enable-fastcgi -enable-safe-mode -with-zlib -with-bz2 -with-freetype-dir -enable-mbstring -with-mysql=/usr/local/mysql -with-mysqli=/usr/local/mysql/bin/mysql_config -with-gd -with-libxml-dir -with-png-dir -with-jepg-dir -enable-socketsrootlocalhost php-5.2.5# make & make install如果本机已经rpm方式安装php，那么进行下边红色字体的动作rootlocalhost php-5.2.5# yum -y remove php*rootlocalhost php-5.2.5# cp php.ini-dist /etc/php.ini 最后测试的部分rootlocalhost # cd /var/www/rootlocalhost www# vi info.php rootlocalhost www# cp /usr/local/httpd/htdocs/index.html .重启的服务就可以出来php那个经典的页面，表示成功！总结，这个实验是为了搭建Nagios和Cacti需要的web环境，接下来的实验就进入Nagios和Cacti的部分！这个实验是Nagios和Cacti安装与配置的第二个步骤之Cacti安装与配置，采用的实验环境是之前搭建的lamp的环境，这步需要安装很多的辅助套件，Cacti就是通过net-snmp进行数据的采集，通过Mysql进行模板、主机信息、以及rra信息的存储，通过RRdtool进行数据的存储和绘图，Cacti是直接与管理员交互的平台。需要安装的套件为rrdtool、net-snmp、cacti-spine、cacti 首先套件安装和设置的具体步骤rootlocalhost # ll rrdtool-1.4.5.tar.gz-rw-r-r- 1 root root 1348713 Oct 152011 rrdtool-1.4.5.tar.gzrootlocalhost # tar zxvf rrdtool-1.4.5.tar.gz rootlocalhost rrdtool-1.4.5# ./configure-prefix=/usr/local/rrdtoolrootlocalhost rrdtool-1.4.5# make & make installrootlocalhost #

useradd cactiuserrootlocalhost # vi /etc/crontab/添加下边的计划任务*/5 * * * * cactiuser /usr/local/php/bin/php /var/www/cacti/poller.php /dev/null 2&1rootlocalhost # mysql /添加必须的cacti这个数据库mysql create database cacti;mysql grant all privileges on cacti.* to identified by 721wyzj;mysql flush privileges;mysql qByerootlocalhost cacti# mysql -p cacti show tables;+-+| Tables_in_cacti |+-+| cdef |.| user_log| version |+-+48 rows in set (0.01 sec)rootlocalhost cacti# cd .rootlocalhost www# chown -R root.root cacti/rootlocalhost cacti# chown -R cactiuser log/ rra/这个是cacti数据交互的地方，cactiuer必须保有写入的权限 rootlocalhost cacti# cd include/rootlocalhost include# cp config.php config.php.bak rootlocalhost include# vi config.php$database_type = mysql;$database_default = cacti;$database_hostname = localhost;$database_username = cactiuser;$database_password = 721wyzj; /修改的部分$database_port = 3306;$database_ssl = false;最后是windows下操作的部分，在IE地址栏里输入以下内容，安装cacti92/cacti/install/index.php安装成功之后，通过账号，密码admin：admin登入进行相关的设置即可总结，这是Nagios和Cacti安装与配置的第二个步骤，主要进行Cacti安装与配置，然而对设备的管理仍需辅以相关的插件来进行，接下来进一步的探索这个是Nagios和Cacti安装与配置的第三个步骤，就是给cacti打补丁和安装weathermap插件，建立在之前的实验平台上，此文章主要介绍安装。第一部分：装cati-plugin的解决方案需要的套件 cacti-plugin-0.8.7h-PA-v3.0.tar.gzrootlocalhost # tar zxvf cacti-plugin-0.8.7h-PA-v3.0.tar.gz rootlocalhost # cd cacti-plugin-arch/rootlocalhost cacti-plugin-arch# cp -rf files/* /var/www/cacti/rootlocalhost cacti-plugin-arch# cd /var/www/cacti/rootlocalhost cacti# mysql -u root cacti admin-Plugin Management (添加上这个即可)实验总结之前一直采用类似以下的方式补丁步骤 patch -p1 -N cacti-plugin-0.8.7g-PA-v2.8.diff之后再修改vi /var/www/cacti/include/global.php$database_username = cactiuser;$database_password = 721wyzj;$configurl_path = /cacti/;但是很无奈登陆时一直出现Call to undefined function api_plugin_hook() 的错误提示，谷歌了好多解决方案，都不奏效，后来发现解开压缩包所在的目录下有files的目录，再结合网络的搜索得知，还有另外一种方案-覆盖，于是就尝试的去做也就是以上成功的案例，终于问题解决，深吸一口气啊！第二部分：weathermap插件的安装rootlocalhost # ll php-weathermap-0.97a.zip -rw-r-r- 1 root root 2927302 Oct 162011 php-weathermap-0.97a.ziprootlocalhost # unz
