Cacti provides a fast poller, advanced graph templating, multiple data acquisition methods, and user management features out of the box. All of this is wrapped in an intuitive, easy to use interface that makes sense for LAN-sized installations up to complex networks with hundreds of devices. = Installing Cacti on Ubuntu 6.06 LTS (Dapper Drake) = == Caveats == * These instructions are for the graphical installer.

Open up a terminal window, easiest to log in as root 2. Install Apache2 (If not already installed) by installing the following packages {{{apache2 }}} (see InstallingSoftware). 3. Install MySQL components (If not already installed) by installing the following packages {{{php5-mysql, mysql-server}}} (see InstallingSoftware). 4. During the mail server installation, select the following options if you're not sure what else to use: {{{Internet Site localhost.localdomain (for the purposes of this install of cacti, i just left this as default)}}} 5. Install Cacti package: {{{cacti}}} (see InstallingSoftware). 6. During the cacti installation, select the following options if you're not sure what else to use: {{{ MySQL server host name: localhost Database name for cacti: cacti Cacti database username: cacti Cacti user password: cacti_password Webserver type: Apache2 }}} 7. Install the MySQL database: (ignore the mysql instructions to change your password; proceed to step 8.) {{{ mysql_install_db }}} 8. Create a MySQL database called "cacti": {{{ mysqladmin --user=root create cacti }}} 9. Type '''mysql''' to enter into MySQL management. 10. At the mysql> prompt, type: {{{ GRANT ALL ON cacti.* TO cacti@localhost IDENTIFIED BY "cacti_password"; }}} NOTE: make "cacti_password" whatever you set the cacti password to during the installation of cacti. 11. Type: {{{ exit }}} 12. Back at the shell type: {{{ zcat /usr/share/doc/cacti/cacti.sql.gz |mysql -u cacti -p cacti }}} 13. You will be prompted for a password here, use the same password again you set during the installation of cacti. == Installing Cacti for Ubuntu - Part 2 == 1. Open a web browser on the machine with cacti installed 2. Type ["http://localhost/cacti"] into the address bar. Note, you can also use the IP address or DNS address of the PC instead of using "localhost".</li> 3. Click '''Next''' 4. Make sure '''New Install''' is selected and click '''Next''' 5. If all steps in Part 1 were followed correctly, all options on this page should show as <font color="green">[FOUND]</font> 6. Make sure '''NET-SNMP 5.x''' and '''RRDTool 1.2.x''' are selected and click '''Next''' 7. At this point, you should be prompted to login. You can use the username '''Admin''' and any password you previously set for this account, if any. The fault password should be '''admin'''. Upon logging in you'll most likely be forced to change your password for security purposes. 8. You should now be logged into cacti, if you need further assistance from here, it most likely won't be ubuntu specific so you should be able to refer to the generic guides on [http://www.cacti.net/] . == Installing Cacti for Ubuntu - Part 3: Errors FAQ (Work In Progress) == '''Q1.''' When I go to localhost/cacti, I keep getting the follow error: {{{ Warning: mysql_connect() [function.mysql-connect]: Access denied for user: 'cacti@localhost' (Using password: YES) in /usr/share/adodb/drivers/adodb-mysql.inc.php on line 338 }}} '''A.''' If you get this error, you've set the wrong password for cacti in mysql. To fix it, follow steps 9 & 10 in Part 1 of this guide. '''A2.''' You can also get this message if you run the GRANT ALL command without the quotes around the password or without the semi-colon at the end. '''Q2.''' The default password won't work when I try to log in through the web interface, how can I log in? '''A.''' Go back to command line and type '''mysql'''. At the mysql> prompt, type: {{{ update user_auth set password = md5('admin') where username = 'admin'; }}} '''Q3.''' I get a "red X" and my graphs will not display properly. '''A.''' I have found that this is because the mysql module sometimes does not get properly registered with PHP. Run the command "php -m" and if you do not see mysql listed then this is your problem. Run the command "dpkg-reconfigure php5-mysql" to correct the problem and then run the command "php -m" again to see if it is now listed. Run the command "apache2ctl restart" to restart the Apache server. CategoryDocumentation CategoryCleanup CategoryDocumentation |
