A detailed tutorial on lamp environment

First, preparatory work

1, install the compilation tool GCC, gcc-c++

Attention to resolve dependencies, recommend the use of Yum installation, if not networked can use the installation CD as a Yum source--

1 Edit Yum configuration file:

# Mount/dev/cdrom/mnt/cdrom

# Vi/etc/yum.repos.d/centos-media.repo

[C5-media]

name=centos-$releasever-media

Baseurl=file:///mnt/cdrom * modified to disc mount point

file:///media/cdrom/

file:///media/cdrecorder/

Gpgcheck=1

Enabled=1 * changed to 1 meaning to enable

Gpgkey=file:///etc/pki/rpm-gpg/rpm-gpg-key-centos-5

2) Shearing/etc/yum.repos.d/centos-base.repo

# Mv/etc/yum.repos.d/centos-base.repo/backup

3 Install GCC and gcc-c++ in turn

# yum-y Install GCC

# yum-y Install gcc-c++

2, turn off the system RPM installation package Apache, MySQL services

Turn off services that are started httpd, mysqld

# Service HTTPD Stop

# Service Mysqld Stop

Determine if the httpd and mysqld of the RPM package installation do not boot from

Chkconfig--level 2345 httpd (mysqld) off

3, turn off SELinux, allow firewall 80 port access

Using Setup

Turn off firewalls and SElinux

1) Close SELinux

# Vi/etc/selinux/config

selinux=disabled * If the SELINUX is not disabled during installation, change the enforcing to Disabled

You need to restart Linux before you can take effect!

2) Shutdown Firewall netfilter/iptables

Because the firewall has not been explained, directly and simply shut down all firewall settings:

# Iptables-f * If firewall is not disabled, the default 80 port is blocked from accessing

Iptables-z

Iptables-x

4, off the unnecessary starting service

# NTSYSV

The following list of services can be maintained from startup, and services that are not listed may be closed:

Atd

Crond # ATD, Crond Scheduled Tasks

Irqbalance

MICROCODE_CTL # System IRQ Port invocation, System services

Network #网络设置

SendMail #邮件

Sshd #远程管理

Syslog #系统日志
