This page shows the prerequisites to install Toolpack 2-5, 2-6, 2-7 or 2-8 for a 64 bits CentOS 5.5 to 5.11 with the use of TelcoBridges repository.

WARNING: The host MUST have at least CentOS 5.5 installed. If you don't want to update your CentOS version to the latest version or want to install the prerequisites for a I386 (32 bits) platform, please follow the manual procedure instead.

WARNING: If you followed the manual procedure on the system before, you MUST NOT use the steps on this page before doing a cleanup of the previously installed files. You should ask Telcobridges support for help with the cleanup.

WARNING: This procedure requires internet access and a DNS configured on your unit.

1 Stop toolpack system (if it is running)
2 TelcoBridges repository
3 Get TelcoBridges repository key
4 CentOS update
- 4.1 Reply to ARP only on local interfaces
- 4.2 Disabling SELinux
5 Install Toolpack Prerequisites
- 5.1 Possible Dependencies Issue
- 5.2 Install Gem
6 Apply kernel patches (if any)
7 Toolpack Development Prerequisite (Optional)
8 Validation Guide (highly recommended)
9 Toolpack System installation

Stop toolpack system (if it is running)

tbtoolpack stop

TelcoBridges repository

Add TelcoBridges repository file

vim /etc/yum.repos.d/TB-Base.repo

Paste the following information in that file:

# TelcoBridges-Base.repo
#
# This repository is using TelcoBridges frozen version of CentOS
# to help client installing the required version of the
# applications required to run Toolpack
#

[tb-base]
name=TelcoBridges-$releasever - Base
baseurl=http://repo.telcobridges.com/centos/5/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5-tb

#released updates
[tb-updates]
name=TelcoBridges-$releasever - Updates
baseurl=http://repo.telcobridges.com/centos/5/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5-tb

Get TelcoBridges repository key

cd /etc/pki/rpm-gpg/
wget http://repo.telcobridges.com/centos/RPM-GPG-KEY-CentOS-5
wget http://repo.telcobridges.com/centos/RPM-GPG-KEY-CentOS-5-tb

CentOS update

Update your system to the latest CentOS 5 version.

yum clean metadata
yum update

If you have the following error:

warning: rpmts_HdrFromFdno: Header V4 DSA signature: NOKEY, key ID c8bf9d3a
Public key for package.rpm is not installed

Make sure that you have the correct gpgkey lines in /etc/yum.repos.d/TB-Base.repo

Reply to ARP only on local interfaces

Modify the file /etc/sysctl.conf to add the following lines:

 net.ipv4.conf.default.arp_ignore=1
 net.ipv4.conf.all.arp_ignore=1

Then restart network interfaces using the following command:

 /etc/init.d/network restart

Disabling SELinux

Check SELinux status

 sestatus

If SELinux is enable, see the Disabling SELinux article to disable it.

Install Toolpack Prerequisites

When asked to 'Importing GPG key', answer yes.

yum groupinstall Toolpack-Prerequisites

Possible Dependencies Issue

If you meet an issue which blocks the installation with error that is related to "dovecot". Do the following and retry the "groupinstall" command to restart installation.

 yum remove dovecot

Install Gem

wget http://download.distribution.telcobridges.com/3rdparty/prerequisite/bin/linux/bundler-1.2.3.gem
gem install --local ./bundler-1.2.3.gem

wget http://download.distribution.telcobridges.com/3rdparty/prerequisite/bin/linux/json-1.7.7.gem
gem install --local ./json-1.7.7.gem

Apply kernel patches (if any)

shutdown -r now

Once rebooted, be sure that Toolpack system is stopped before manipulating MySQL.

tbtoolpack stop

Configure ODBC

vim /etc/odbcinst.ini

Remove the '#' in front of each lines of the [MySQL] section Modify the 'Driver' line to set the correct driver

Example for 32 bits system:

[MySQL]
Description     = ODBC for MySQL
Driver          = /usr/lib/libmyodbc5.so
Setup           = /usr/lib/libodbcmyS.so
FileUsage       = 1

Example for 64 bits system:

[MySQL]
Description     = ODBC for MySQL
Driver          = /usr/lib64/libmyodbc5.so
Setup           = /usr/lib64/libodbcmyS.so
FileUsage       = 1

Configure MySQL

vim /etc/my.cnf

Add these variables in the file under the [mysqld] section:

log-bin
server-id=[UniqueId]

The server-id needs to be a non-zero unique value (do not use 0). If you use the host redundancy feature, the value needs to be different on each host .

Add max_allowed_packet to increase the maximum size of binary blobs in the database. Make sure it is in the [mysqld] section AND [mysqldump] section

 max_allowed_packet = 200MB

Add below to remove database dependencies with DNS servers (**Applicable to TMG users only)

 skip-name-resolve

Add this to make sure the mysql logs don't get too big

 expire_logs_days=60

Example:

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
log-bin
server-id=5876
max_allowed_packet = 200MB
expire_logs_days=60

# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

# Added so that problems with DNS servers don't cause problems with the mysql DB
# Note: This is applicable only if you are using a TMG
skip-name-resolve

[mysqldump]
max_allowed_packet = 200MB

Start MySQL

service mysqld start

Configure MySQL Users

Set password for the root user to 'tbdbpw' (TelcoBridges recommends that you set your own password for root)
Enable root connection from localhost only
Create a tbdb user (required by Toolpack)
Remove anonymous connection

Example:

/usr/bin/mysqladmin -u root password tbdbpw

mysql -uroot -ptbdbpw
DELETE FROM mysql.user WHERE !(Host = 'localhost' AND User = 'root');
FLUSH PRIVILEGES;
CREATE USER 'tbdb'@'%' IDENTIFIED BY 'tbdbpw';
GRANT ALL PRIVILEGES ON *.* TO 'tbdb'@'%' IDENTIFIED BY 'tbdbpw';
FLUSH PRIVILEGES;
exit

Toolpack Development Prerequisite (Optional)

The Toolpack System Development prerequisite section is only required for customers that will develop their own application using the Toolpack API:

yum install gcc-c++ libxml2-devel libpcap-devel unixODBC-devel libaio libaio-devel

Validation Guide (highly recommended)

If you would like to verify your installation go to the Toolpack Validation Guide

Toolpack System installation

Now that the prerequisite are installed, now it is time to install the Toolpack system
