企业级监控工具cacti安装配置全过程

标签：cacti 服务器监控

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.jerry.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.jerry.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
