This page shows the Toolpack 2-5, 2-6 and 2-7 prerequisites for CentOS 5.5, 5.6, 5.7 and 5.8.
WARNING: The host MUST have CentOS 5.5, 5.6, 5.7 or 5.8 installed. If you don't want to update your host, 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.
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 #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
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
