There’s an easy way of installing Apache, Mysql and PHP and it’s via yum. You can install or update httpd,mysql-server and php, php-mysql and some minor changes on your configuration files and you’re good to go. Well, the procedure below is one way to install also, if you’re quite bored and want to develop your sysadmin skills.
I. Operating System Installation
1. The typical type of installation is thru CD-ROM or DVD. If you want network install, you should have a CentOS boot disk to boot the server
How to create boot disk?
A. how to create boot disk in linux
a. insert CD then copy boot.iso to a folder
#cp boot.iso /home/test/
b.unmount the cd-rom
#cd; eject
c. Insert the blank cdr and find the dev name
cdrecord -scanbus
d. Write the .iso to that blank cd
#cdrecord -v -dao dev=1,2,3 /home/test/boot.iso
the 1,2,3 value is just a sample. Just replace it with the actual device name that you get upon running
the cdrecord -scanbus.
B. how to create boot disk in windows
a. copy boot.iso in any folder
b. run your favorite cd burning program and open boot.iso
c. start the cd writing process
2. Assign a static IP address & the hostname for the server.
3. Select network install from FTP or NFS depends on your setup
ex:
ftp: 192.168.17.100
path: /pub/centos5
Setting up NFS or FTP is discussed on the other tutorial
4. When finish, do the update. The -y parameter denotes automatic update and install of the package, no more prompt.
#yum –y update
5. Configure the file “network” at /etc/sysconfig/network with the following lines.
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=localhost.localdomain
6. Configure the file “ifcfg-eth0” at /etc/sysconfig/network-scripts/ifcfg-eth0 with the following lines.
# Broadcom Gigabit Ethernet
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
HWADDR=00:29:EE:F2:45:4L
IPADDR=Static IP Address (Example: 192.168.17.5)
NETMASK=Subnet Mask (Example: 255.255.255.0)
GATEWAY=Gateway IP address (Example: 192.168.17.1)
7. Configure the file “hosts” at /etc/hosts with the following lines. (optional)
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
10.0.0.174 c5.freelinuxtutorials.com c5 (Add the server hostname here)
::1 localhost6.localdomain6 localhost6
8. Configure your DNS at /etc/resolv.conf with the following lines.
nameserver Primary DNS (Example: 192.168.17.228)
search freelinuxtutorials.com
9. Restart the network interface by the following commands.
#service network restart
10. Close unnecessary services via the “setup” menu tool or use chkconfig to turn off auto start of certain services
e.g.
#chkconfig cups off
#chkconfig nfslock off
11. After first restart, check your logs to see some errors
cat /var/log/messages |grep error cat /var/log/messages |grep warning
II. Apache Installation
1. Apache can be installed as package during custom selection of packages on the installation process, labeled as “Web Server”
2. Make Apache service start on boot-up via:
# chkconfig httpd on
Let say the default version of your apache is 2.2.3 and you want to upgrade it to the latest version
UPGRADING OF APACHE 2.2.3 TO APACHE 2.2.4
1. # yum remove httpd
Removing:
httpd x86_64 2.2.3-7.el5.centos installed 2.9 M
Removing for dependencies:
httpd-devel x86_64 2.2.3-7.el5.centos installed 512 k
httpd-devel i386 2.2.3-7.el5.centos installed 512 k
2.
shell# rm –rf php-5.2.3
3. Download httpd-2.2.4-4.x86_64.rpm from http://rpmfind.net/
4. Download httpd-devel-2.2.4-4.x86_64.rpm from http://rpmfind.net/
5. Download lib64db4.5-4.5.20-1mdv2007.1.x86_64.rpm http://rpmfind.net/
6. Install lib64db4.5-4.5.20-1mdv2007.1.x86_64.rpm
Shell# rpm –Uvih lib64db4.5-4.5.20-1mdv2007.1.x86_64.rpm
7. Install httpd-2.2.4-4.x86_64.rpm
Shell# rpm –Uvih httpd-2.2.4-4.x86_64.rpm
8. Install httpd-devel-2.2.4-4.x86_64.rpm
Shell# rpm –Uvih httpd-devel-2.2.4-4.x86_64.rpm
G. MySQL Installation
1. Download the MySQL software at http://www.mysql.org.
2. Select Linux Source to download. File name should be “mysql-5.0.41.tar.gz”
3. Before installation, ensure that gcc compiler has installed. Please verify by
gcc –v
If gcc does not install, please install it by
yum install gcc
4. Install gcc-c++ compiler by
yum install gcc-c++
5. Install the ncurses-devel library by
yum install ncurses-devel
It is require by the MySQL during compile process.
6. Run the following commands.
shell> groupadd mysql shell> useradd -g mysql mysql shell> gunzip < mysql-VERSION.tar.gz | tar -xvf - shell> cd mysql-VERSION shell> ./configure --prefix=/usr/local/mysql shell> make shell> make install shell> cp support-files/my-medium.cnf /etc/my.cnf shell> cd /usr/local/mysql shell> chown -R mysql . shell> chgrp -R mysql . shell> bin/mysql_install_db --user=mysql shell> chown -R root . shell> chown -R mysql var shell> bin/mysqld_safe --user=mysql &
7. To make MySQL start automatically after reboot, do the following.
shell> cp /mysql-VERSION/support-files/mysql.server /etc/init.d/mysql shell> chmod +x /etc/init.d/mysql shell> chkconfig --add mysql
8. To test the MySQL, type the following command.
shell>/usr/local/mysql/bin/mysqladmin version
If it can display the version, installation is preliminary success.
9. Do the following simple testing.
shell>mysql
mysql> show databases;
+——————–+

+——————–+
| information_schema |
| mysql |

10. Add password for “root” in MySQL Database by typing the following commands. The default password is same as Linux root password.
shell> mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD(‘default password’) WHERE user=’root’;
mysql> FLUSH PRIVILEGES;
11. Test it by the following commands.
shell>mysql - u root - p Enter password: ********

Thankyou for this great tutorial.
no problem. thanks for dropping by 🙂
Thanx 🙂 Couldn’t find Apache 2.2.4 on ftp://rpmfind.net/linux/centos/5.9/os/x86_64/CentOS/ :'( For my CentOS 5.9 (Final) I want to use mod_spdy, can you help?
