Upgrade Redmine from 2.0.3 to 2.3.3, ruby 1.9.1 to 2.0

1.First backup everything:

1.1 backup database
1.2 backup redmine folder
1.3 backup /usr/local/ if you installed ruby manually.

2.Stop httpd service:


 service httpd stop

3.Upgrade Rails version to 3.2.13

4.Remove ruby 1.9.1


rm -rf /usr/local/lib/ruby/1.9.1/
rm -rf /usr/local/lib/ruby/gems/1.9.1/
rm -rf /usr/local/include/ruby-1.9.1/

5.Install ruby 2.0


wget http://cache.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p247.tar.gz
tar -xzvf ruby-2.0.0-p247.tar.gz
cd ruby-2.0.0-p247
./configure
make
make install
ruby -v
which ruby

6.Copy redmine config file to New stable 2.3.3



wget http://rubyforge.org/frs/download.php/77138/redmine-2.3.3.tar.gz
tar -xzvf redmine-2.3.3.tar.gz

  cp /var/lib/redmine/config/database.yml ./config/database.yml
  cp /var/lib/redmine/config/configuration.yml.example ./config/configuration.yml
  cp /var/lib/redmine/files/* ./files/
  rm ./files/delete.me

7.Copy plugins (version >= 2.0)


  cp -r /var/lib/redmine/plugins/ ./plugins/

8.Re-compile passenger:


 gem install passenger --no-rdoc --no-ri
 passenger-install-apache2-module

9.Configure Apache mode: /etc/httpd/conf.d/passenger.conf


# Passenger Basic Setting

Install libevent for CentOS RHEL OEL

Default way install library will put everything into /usr/local.

To keep it more Redhat looks:

1.First remove the old library to avoid any conflict:


yum erase libevent*

2.Download and uncompress the package:


wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
tar xzvf libevent-2.0.21-stable.tar.gz

3.Compile and install into /usr/lib:


cd libevent-2.0.21-stable
make clean
./configure --prefix=/usr
make
make install

You should have it under /usr/lib, with correct /usr/lib/pkgconfig. Not changes LD_LIBRARY_PATH needed at all!

4.If unhappy with where it installed, uninstall anytime:


cd libevent-2.0.21-stable
make uninstall

Installing oracle instant client on CentOS RHEL OEL 5.9

This is a guide of Install sqlplus with the minimal oracle-software fingerprint.

I try to not install the Oracle Client in my computers, it modify lots of registry in Windows, and in linux you need XWindow GUI or remote XWindow plus set lots of environment variables and deal with Oracle Universal Installer (OUI) that depends on many packages, versions, java … etc.

1.First Download the package from Oracle Instant Client

2.Install the 2 packages matchs your OS, I am using OEL 5.9 x86 as example:


 rpm -ivh oracle-instantclient-basic-10.2.0.5-1.i386.rpm
 rpm -ivh oracle-instantclient-sqlplus-10.2.0.5-1.i386.rpm

3.You should have a structure and files like:


 /usr/lib/oracle/10.2.0.5/client/bin/genezi
                                     sqlplus
 /usr/lib/oracle/10.2.0.5/client/lib/glogin.sql
                                     libsqlplusic.so
                                     libsqlplus.so
                                     libocci.so.10.1
                                     libocijdbc10.so
                                     ojdbc14.jar
                                     libclntsh.so.10.1
                                     libnnz10.so
                                     libociei.so

4.Add lib to ldconfig


 vi /etc/ld.so.conf.d/oracle.conf
                   /usr/lib/oracle/10.2.0.5/client/lib
 re-run: #//sbin/ldconfig
 to active the changes

5.create a tnsnames.ora at /etc:


PRODUCT_ORA1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.4)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = ora1)
    )
  )

6.To test it out:


 /usr/lib/oracle/10.2.0.5/client/bin/sqlplus sys@PRODUCT_ORA1

Configure network bonding Link Aggregation using LACP under RHEL CentOS OEL 5.9

I wrote this from the work on OEL 5.9 64 bit.

The server has 2 physical NICs bonding into 1 IP address.

1.Config the initial bonding configuration

1.1 eth0
# cat /etc/sysconfig/network-scripts/ifcfg-eth0


# Emulex Corporation OneConnect 10Gb NIC (be3)
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no

1.2 eth1
# cat /etc/sysconfig/network-scripts/ifcfg-eth1


# Emulex Corporation OneConnect 10Gb NIC (be3)
DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no

1.3 bond0
# cat /etc/sysconfig/network-scripts/ifcfg-bond0


# Bonding Network
DEVICE=bond0
USERCTL=no
BOOTPROTO=none
ONBOOT=yes
IPADDR=10.144.244.14
NETMASK=255.255.255.0
NETWORK=10.144.244.0
GATEWAY=10.144.244.1
TYPE=Unknown
IPV6INIT=no

2.Config Bonding modules

2.1 Bonding settings
# cat /etc/modprobe.conf


alias scsi_hostadapter shpchp
alias eth0 be2net
alias eth1 be2net
alias scsi_hostadapter1 cciss
alias scsi_hostadapter2 usb-storage
alias bond0 bonding
options bond0 miimon=100 mode=4 lacp_rate=1

2.2 Load the bonding modules into the “running” kernel


# modprobe bond0
# lsmod | grep bond
bonding        126649    0

3.Configure your network settings
# cat /etc/sysconfig/network


NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=DB01.milliondollarserver.com

4.Restart the network stack
# service network restart

5.Check the routing configuration
# route -n

6.Check bonding stack for errors
# cat /proc/net/bonding/bond0

Recommend SWAP size for Linux

SWAP file usage in our Linux distribution is common to most all other Linux versions and so information gained from other systems running Linux should be usable in FreeBSD or Debian.

So to begin, SWAP disk space is used when we begin to run out of main RAM memory, using it just as if it were regular memory.
SWAP space prevents us from running out of memory, which can be a very bad problem should it occur.
SWAP space is also used with the computer function called Hibernate, where all of the computer memory state is saved to your hard disk and can be restored at a later date.

In this article though, we are concerned about its usage as memory.
So, the first thing to decide, is how much should you create, when you install the OS?

If you are like me, you often just go with the default of 2.00 GB or so.
But apparently, there are some basic recommendations for this SWAP file size to be created according to Red Hat recommendations.

Code:
RAM Memory SWAP File Size

Up TO 4GB 2GB
4GB TO 16GB 4GB
16GB TO 64GB 8GB
64GB TO 256GB 16GB

Run command to check space:

free -m
total used free shared buffers cached
Mem: 1877 1690 187 0 8 177
-/+ buffers/cache: 1504 372
Swap: 1999 0 1999

Install Openfire Chat Server at RHEL/CentOS/OEL 6

# wget http://download.igniterealtime.org/openfire/openfire-3.8.1-1.i386.rpm
# rpm -ivh openfire-3.8.1-1.i386.rpm
# service openfire start

check out the /opt/openfire/logs

Found it can't start.

I got it to start on RHEL 6 64 bit by installing the 32 bit library
yum install libldb.i686

It's actually just zlib.i686 it needs.
Installing libldb isn't necessary, but it installs zlib as a dependency.

Then goto http://[Server IP]:9090

Domain:
Admin Console Port:9090
Secure Admin Console Port:9091
Standard Database Connection:

Install mysql database to support it or use internal DB for small group.

# yum install mysql-server.x86_64
# service mysqld start
# /usr/bin/mysql_secure_installation
# chkconfig mysqld on

Create an new openfire database and user.

# chkconfig openfire on

Recompile Install Red Hat Enterprise MRG Realtime at Oracle Enterprise Linux CentOS

If you want to recompile the RT kernel with your custom settings you can download the source RPMS here:

http://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/RHEMRG/SRPMS/

First download the SRPM:

wget http://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/RHEMRG/SRPMS/kernel-rt-version.src.rpm

Then install it:

rpm -ivh kernel-rt-version.src.rpm

Once you have installed it and built the spec file you'll then be able to run (from the RPMBUILD folder):

make menuconfig

This will allow you to configure the linux kernel as you wish. You can then create the RPM file and install your new kernel.

SELinux cause PostgreSQL error: could not connect to server: Permission denied

The php command line works but not the apache page.

Error message:

pg_connect(): Unable to connect to PostgreSQL server: could not connect to server: Permission deniednt
Is the server running on host "localhost" (::1) and acceptingnt
TCP/IP connections on port 5432?ncould not connect to server: Permission deniednt
Is the server running on host "localhost" (127.0.0.1) and acceptingnt
TCP/IP connections on port 5432? in /home/www/htdocs/test.php on line 3

If you don't want to be using SELinux then disabling it is an option, but if you prefer the other protection it offers you may just want to enable the specific permission to allow Apache to issue HTTP connections.

As root, running:

# service httpd stop
# service postgresql-9.2 stop

# setsebool -P httpd_can_network_connect 1

# service httpd start
# service postgresql-9.2 start

Oracle Enterprise Linux 6.3 Small Smart ISO Release 1

I started this from Oracle's website:

Oracle Linux Download

Anyone can download the file from the mirror servers.
http://mirrors/pub/OracleLinux/OL6/U3/x86_64/OracleLinux-R6-U3-Server-x86_64-dvd.iso

Then I trim it down to less than 400MB.
Then add my kickstart script.

Please notice this is a fully automatic installation ISO.
It will clean all the data of the server you are going to boot from it!!!!!!

Highly recommand you run it from VM Player or VM Box or an old server, before put it to production.

I will make an youtube video to show you how it works.

After installation the password will be my domain name: www.milliondollarserver.com

The first release ISO file can be download at here.

Please give me some feed back after try it.

Demo of how to use the ISO install a server on YouTube

Setting up Oracle Linux 6 with public-yum for all updates

After Install Oracle Linux from the ISO or DVD image, you will need add yum repository.

Log in as user root
Download the yum repo file from http://public-yum.oracle.com

# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-ol6.repo

If you want, you can edit the repo file and enable other repositories, I enabled [ol6_UEK_latest] by just setting enabled=1 in the file with a text editor.
Run yum repolist to show the registered channels and you see we are including everything including the latest published RPMs.

Now you can just run

yum update

I will add this into my ISO, make it automatic.

Start something new.

For All the friends who check my site, this year I will start something new, something I hope will benefit everyone.

I always like something small and fast.
That is why when downloading Linux ISOs, I will pick *mnimal*.iso to try it.

Debian has it, CentOS has it.
Oracle Enterprise Linux don't!

Been search around for days, no luck.

Then I start building my own.

Before I start, I would love to thank people who make this possible:

All the OpenSource Heros.
Red Hat, Inc.
ORACLE CORPORATION.

If Oracle or RedHat think this affect your business, please let me know.

MILLION DOLLAR SERVER
