企业级监控工具Cacti安装配置全过程

 

Cacti 在英文中的意思是仙人掌的意思,Cacti是一套基于PHP,MySQL,SNMP及RRDTool开发的网络流量监测图形分析工具。它通过 snmpget来获取数据,使用 RRDtool绘画图形,而且你完全可以不需要了解RRDtool复杂的参数。它提供了非常强大的数据和用户管理功能,可以指定每一个用户能查看树状结 构、host以及任何一张图,还可以与LDAP结合进行用户验证,同时也能自己增加模板,功能非常强大完善。

基础信息:

OS:RHEL 5.8

SOFT: apr-util-1.4.1.tar.bz2  cmake-2.8.6.tar.gz  libmcrypt-2.5.8.tar.gz  php-5.4.36.tar.bz2

            rrdtool-1.4.7.tar.tar    apr-1.4.6.tar.bz2    cacti-0.8.8c.tar.gz      httpd-2.4.2.tar.bz2

            mysql-5.5.22.tar.gz    php-5.4.5.tar.bz2

首先编译安装LAMP平台,建议卸载掉对应rpm包,否则在各程序协作的时候可能会有问题。

1.install apr and apr-util:


2.tar xf apr-1.4.6.tar.bz2 

cd apr-1.4.6

./buildconf

./configure --prefix=/usr/local/apr

make

make install

 

tar xf apr-util-1.4.1.tar.bz2

 

cd apr-util-1.4.1 

./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr

make

make install


3.install apache:

 yum -y install pcre-devel

tar xf httpd-2.4.2.tar.bz2 

cd httpd-2.4.2

./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd --enable-so --enable-suexec --enable-ssl --enable-rewrite --enable-rewrite --with-zlib --with-pcre --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-modules=most --enable-modules-shared=most --enable-mpms-shared=all 

make

make install

 

echo "PATH=\$PATH:/usr/local/apache/bin" >> /etc/profile

export PATH=$PATH:/usr/local/apache/bin

echo "MANPATH  /usr/local/apache/man " >> /etc/man.config

ln -sv /usr/local/apache/include /usr/include/httpd


4.install cmake:

tar xf cmake-2.8.8.tar.gz

cd cmake-2.8.8

./bootstrap

make

make install


5.install mysql

groupadd -r mysql

useradd -g mysql -r -d /data/mysql mysql

tar xf mysql-5.5.22a.tar.gz

cd mysql-5.5.22a

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DSYSCONFDIR=/etc -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1  -DWITH_READLINE=1 -DWITH_SSL=system -DWITH_ZLIB=system -DWITH_LIBWRAP=0 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DENABLE_PROFILING=1 

make

make install

 


6.cd /usr/local/mysql


chown -R :mysql .

mkdir -pv /data/mysql

chown -R mysql:mysql /data/

cp /usr/local/mysql/support-files/my-large.cnf /etc/my.cnf

cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld

chmod +x /etc/rc.d/init.d/mysqld

chkconfig --add mysqld

scripts/mysql_install_db --user=mysql --datadir=/data/mysql

sed -i '/\[mysqld\]/a \datadir = /data/mysql' /etc/my.cnf

sed -i 's/thread_concurrency = 8/thread_concurrency = 2/g' /etc/my.cnf

echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile

export PATH=$PATH:/usr/local/mysql/bin

echo "MATHPATH /usr/local/mysql/man" >> /etc/man.config

ln -sv /usr/local/mysql/include /usr/include/mysql

echo " /usr/local/mysql/lib " >> /etc/ld.so.conf.d/mysql.conf

ldconfig

service  mysqld start

6.install php

安装php之前有可能会要求安装libmcrypt,我直接在chinaunix下载的源码 编译安装即可,然后编译PHP时加上 --with-mcrypt=DIR

tar xf  php-5.4.4.tar.bz2

cd  php-5.4.4

./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-openssl --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml  --with-apxs2=/usr/local/apache/bin/apxs --with-mcrypt  --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 --enable-sockets 

make

make install 

cp php-5.4.4/php.ini-production /etc/php.ini

echo "AddType application/x-httpd-php  .php " >> /etc/httpd/httpd.conf

echo "AddType application/x-httpd-php-source  .phps" >> /etc/httpd/httpd.conf

sed -i 's/DirectoryIndex index.html/DirectoryIndex index.php index.html/g' /etc/httpd/httpd.conf

上面所有操作无错误执行完以后可以建个测试php页测试下是不是OK,如果没问题,开始装cacti部分:

 1.我为cacti直接建立的虚拟主机:

首先修改httpd.conf添加:include /etc/httpd/extra/httpd-vhosts.conf

然后修改http-vhosts.conf:

<VirtualHost *:80>
    DocumentRoot "/usr/local/apache/htdocs/cacti
    ServerName cacti.linuxidc.com
    ErrorLog "logs/cacti-error_log"
    CustomLog "logs/cacti-access_log" common
</VirtualHost>

2.安装rrdtool:

tar xf rrdtool-1.4.7.tar.gz

cd rrdtool-1.4.7

./configure --prefix=/usr/local/rrdtool

make

make install

echo "MANPATH  /usr/local/rrdtool/share/man" >> /etc/man.config

echo "PATH=$PATH:/usr/local/rrdtool/bin " >> /etc/profile

export PATH=$PATH:/usr/local/rrdtool/bin

ln -sv /usr/local/rrdtool/include /usr/include/rrdtool

echo "/usr/local/rrdtool/lib" >> /etc/ld.so.conf.d/rrdtool.conf

ldconfig

3.yum安装net-snmp、net-snmp-util并设置自动运行,此处不给详细命令了

4.安装cacti

为cacti创建数据库,并初始化所需要表:

1.mysqladmin create cacti      //此时的密码为mysql的密码

2.cd /usr/local/apache/htdocs/cacti 

3.mysql cacti < cacti.sql

创建mysql用户,使用cacti能访问其cacti数据库

mysql -e "GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'cactiuser'";

1.//创建了用户cactiuser 密码也为cactiuser 

2.mysqladmin -p flush-privileges 

3.mysql -ucactiuser -p          //验证一下是否正确 

接着创建系统用户cactiuser,以之运行cacti的数据获取和日志记录等工作

1.useradd cactiuser 

2.chown -R cactiuser:cactiuser /usr/local/apache/htdocs/cacti/{log,rra}

以cactiuser用户的身份,每5钟获取一次数据:

1.echo '*/5 * * * *  /usr/local/php/bin/php /usr/local/apache/htdocs/cacti/poller.php &> /dev/null' > /var/spool/cron/cactiuser 

修改php时区:

1.vim /etc/php.ini

2.date.timezone = Asia/Shanghai 

编辑cacti的配置文件include/config.php启用并修改如下行:
//$url_path = "/cacti/";
我们这里将之修改为:
$url_path = "/";

而后在浏览器中打开http://cacti.linuxidc.com,按提示一步步配置即可完成安装。
密码第一次输入的时候,会让修改密码,用户默认为admin 密码为admin
