Testing Environment: CentOS

This page documents the process for installation of Cacti 1.x on CentOS Versions 6.9 and 7.5

It follows the conventions documented in the Test Environments: Before You Start

---

CentOS 6

System setup

Configure the network

hostname _ssh_host_
echo "_ssh_host_" > /etc/hostname
system-network-config
yum install -y screen git
useradd _ssh_user_
passwd _ssh_user_
echo "_ssh_user_     ALL=(ALL)     ALL" > /etc/sudoers.d/_ssh_user_

Note: Do NOT use a filename with a fullstop in it as sudo will ignore these by default

Enable SSH login via keys

Create the authorized_keys file with the appropriate SSH keys

mkdir -p ~/.ssh
touch ~/.ssh/authorized_keys
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

If you have predefined keys you wish to insert, simply edit the ~/.ssh/authorized_keys file

Install Apache, SQL and PHP

Package selection may be overkill but to ensure they are definitely installed.

yum install -y httpd mod_sql openssl mysql mysql-server php php-mysql php-xml php-mbstring php-cli php-common php-pdo php-gd
yum install -y centos-release-SCL && yum install -y php54 php54-php php54-php-gd php54-php-mbstring php54-php-mysqlnd php54-php-snmp php54-php-ldap
yum install -y net-snmp net-snmp-utils rrdtool

chkconfig httpd on
chkconfig mysqld on

Website basics

Create some required directories

mkdir -p /var/log/cacti \
/var/www/html/cacti/site \
/var/www/html/cacti/develop \
/var//www/html/cacti/feature \
/etc/pki/tls/cacti/

Clone Cacti

Run the following as _ssh_user_

sudo su - _ssh_user_
cd /var/www/html/cacti
git clone https://github.com/netniv/cacti/ site
cd site/
git remote add upstream https://github.com/cacti/cacti/ && git fetch --all 
cd ../
cp -Rv site develop
cp -Rv site feature

cd /var/www/html/cacti/develop && git branch develop --set-upstream upstream/develop && git checkout develop
cd /var/www/html/cacti/feature && git branch feature/1.2.x --set-upstream upstream/feature/1.2.x && git checkout feature/1.2.x

Change default permissions

Run the following as root

chown _ssh_user_:apache -Rv /var/www/html/cacti/
chmod u+rw,g+r,g-w,a+r -Rv /var/www/html/cacti
chmod u+rw,g+rw,a+r -Rv \

/var/www/html/cacti/site/resource/ \
/var/www/html/cacti/feature/resource/ \
/var/www/html/cacti/develop/resource/

Checkout specific versons

cd /var/www/html/cacti/site/ && git checkout release/_cacti_version_ 
cd /var/www/html/cacti/develop && git branch develop --set-upstream upstream/develop && git checkout develop
cd /var/www/html/cacti/feature && git branch feature/1.2.x --set-upstream upstream/feature/1.2.x && git checkout

System setup

Configure the network

hostname _ssh_host_
echo "_ssh_host_" > /etc/hostname
nmtui
yum install -y screen git
useradd _ssh_user_
passwd _ssh_user_
echo "_ssh_user_     ALL=(ALL)     ALL" > /etc/sudoers.d/_ssh_user_

Note: Do NOT use a filename with a fullstop in it as sudo will ignore these by default

Enable SSH login via keys

Create the authorized_keys file with the appropriate SSH keys

mkdir -p ~/.ssh
touch ~/.ssh/authorized_keys
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

If you have predefined keys you wish to insert, simply edit the ~/.ssh/authorized_keys file

Install Apache, SQL and PHP

Package selection may be overkill but to ensure they are definitely installed.

yum install -y httpd mod_ssl openssl mariadb-server mariadb php php-mysql php-xml php-mbstring php-gd php-cli php-common php-pdo php-posix php-ldap net-snmp net-snmp-utils rrdtool policycoreutils-python

systemctl enable mariadb
systemctl start mariadb
mysql_secure_installation
systemctl enable httpd
systemctl restart httpd

Website basics

Create some required directories

mkdir -p /var/log/cacti \
/usr/share/cacti/site \
/usr/share/cacti/develop \
/usr/share/cacti/feature \
/etc/pki/tls/cacti/

ln -s /usr/share/cacti /var/www/html/cacti

Clone Cacti

cd /usr/share/cacti
git clone https://github.com/cacti/cacti/ site

If you are using your own repo change the URL above and then add an upstream using:

cd site/
git remote add upstream https://github.com/cacti/cacti/ && git fetch --all 
cd ../

Create development and feature branch sites (use git checkout to change the branch to what you want)

mkdir develop
mkdir feature

cp -Rv site/. develop
cp -Rv site/. feature

Change default permissions

Run the following as root

chown _ssh_user_:apache -Rv /usr/share/cacti
chmod u+rw,g+r,g-w,a+r -Rv /usr/share/cacti
find /usr/share/cacti -maxdepth 1 -type d -exec chmod u+rw,g+rw,a+r -Rv {}/{log,rra,resource,scripts,cache}/ \;

semanage fcontext -a -t httpd_sys_content_t "/usr/share/cacti(/.*)?"
semanage fcontext -a -t httpd_sys_rw_content_t "/usr/share/cacti/(.*)/((log|rra|resource|scripts|cache)(/.*)?)"
semanage fcontext -a -t httpd_sys_content_t "/usr/share/cacti/.*/.htaccess"

Checkout specific versons

The following are the different ways you can checkout various branches/tags

cd /var/www/html/cacti/site/ && git checkout release/_cacti_version_
cd /var/www/html/cacti/develop && git branch develop --set-upstream upstream/develop && git checkout develop

Configuration MySQL

### Start/stopping safe-mode MariaDB
To enter safe mode:
```shell
systemctl stop mariadb
rm -f /var/lib/mysql/ib_logfile{0,1}
sudo -u mysql /usr/libexec/mysqld --skip-grant-tables &

Wait for the MariaDB version to appear.

When you want to return to normal service operation:

mysqladmin -u root -p shutdown
systemctl start mariadb

Update issues

For upgrade issues, ensure MariaDB is in safe mode (see above):

mysql_upgrade

Password reset

To reset root password, ensure that MariaDB is in safe mode (see above):

mysql

This should take you straight in (or the above system stop did not work)

mysql> update mysql.user set Password=PASSWORD('your desired password') where user='root';

If you still have issues, chech that there is a 'localhost' in the Host column for root. You may find changing the IPv6 local loopback to localhost helps:

mysql> update mysql.user set host = 'localhost' where host = '::1' and user='root';

You need to insert a record otherwise.

Once all OK, flush the privileges (at this point passwords will be required again):

mysql> flush privilegs;
mysql> quit
