Build Lamp environment: (move the extracted lamp directory to the "/" directory)

I. preparatory work

1. Install the compilation tools gcc and gcc-c++

Pay attention to solving the dependency, it is recommended to use yum installation, if you can not connect to the network, you can use the installation CD as the yum source--

1) Edit the yum configuration file:

# mount / dev/cdrom / mnt/cdrom

# vim / etc/yum.repos.d/CentOS-Media.repo

[c6-media]

Name=CentOS-$releasever-Media

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

Gpgcheck=0

Enabled=1 * changed to 1 means to enable

Gpgkey= file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

2) cut / 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. Disable the Apache and MySQL services of the system RPM installation package

Shut down the started services httpd and mysqld

# service httpd stop

# service mysqld stop

Make sure that the httpd and mysqld installed in the rpm package cannot be booted automatically

Chkconfig-level 2345 httpd (mysqld) off

3. Close SELinux and allow firewall port 80 to access.

1) close SELinux

# vim / etc/selinux/config

SELINUX=disabled * if SELinux is not disabled during installation, change enforcing to disabled

After modification, you need to restart Linux to take effect!

2) turn off the firewall Netfilter/iptables

As the firewall has not yet been explained, simply turn off all firewall settings:

# iptables-F * if the firewall is not disabled, access to port 80 is prohibited by default

Iptables-An INPUT-p tcp-dport 80-j ACCEPT

Iptables-Z

Iptables-X

4. Turn off unnecessary self-starting service

# ntsysv

The following list of services can remain self-starting, and unlisted services can be turned off:

Atd

Crond # atd, crond scheduling tasks

Irqbalance

Microcode_ctl # system irq port invocation, system service

Network # Network Settings

Sendmail # Mail

Sshd # remote Management

Syslog # Syslog

5. Copy the source package, unpack and decompress (pay attention to whether the unzip software is installed on the system)

It is recommended to store the LAMP environment installation source code package in one directory, such as / lamp

You can write a batch processing script to unpack all .tar.gz installation packages at once.

# vim tar-for-if.sh

#! / bin/bash

Ls * >. / list.txt

For an in $(cat list.txt)

Do

If [["$a" = ~ "tar"]]

Then

Tar-xf $a

Elif [["$a" = ~ "tgz"]]

Then

Tar-xf $a

Elif [["$a" = ~ "gz"]]

Then

Gunzip $a

Elif [["$a" = ~ "bz"]]

Then

Bunzip2 $a

Elif [["$a" = ~ "zip"]]

Then

Unzip $a

Else

Echo "$an is not a zip file."

Fi

Done

6. Check to confirm that the disk space is not full.

Df-h

* if / partition is full, you can move the installation package to another partition or delete other useless files

How to determine the error report:

1) the installation process stops

2) after stopping, error or warning appears in the one-page interface

How to determine the success of the installation:

Enter the installation directory and confirm that the installer appears, which is a success.

II. Compilation and installation

* after the compilation and installation of each source package configuration is completed, confirm whether the installation files are generated in the installation directory

# install libxml2

Libxml2 is a xml c language parser, originally developed for the Gnome project tool, is a MIT License-based free and open source software. It not only supports the c language version, but also supports the binding of C++, PHP, Pascal, Ruby, Tcl and other languages, and can run on Windows, Linux, Solaris, MacOsX and other platforms. The function is still quite powerful, and I believe there is no problem in meeting the needs of general users.

Libxml is a library for parsing XML documents. It is written in C language, and can be called by many languages, such as C language, C language. Che, Python,Kylix/Delphi,Ruby, and PHP, etc. The XML::LibXML module can also be used in Perl. It was originally developed for GNOME, but now it can be used in a variety of ways. LibXML code is very portable because it is based on the standard ANSI C library and is licensed under the MIT license.

Zlib is a function library for data compression, developed by Jean-loup Gailly and Mark Adler. The first version 0.9 was released on May 1st, 1995. Zlib uses the DEFLATE algorithm, which was originally written for the libpng library and has since been widely used by many software. This function library is free software and uses zlib license

* if you prompt / usr/local/apache2/modules/mod_deflate.so to have no permission at startup, you can close SELinux or execute the command chcon-t texrel_shlib_t / usr/local/apache2/modules/mod_deflate.so. The problem that the .so file cannot be loaded or has no permission is a SELinux problem, which can be solved by using the command: "chcon-t texrel_shlib_t file name". MySQL and Apache may also have similar problems.

Enter the address through the browser to access: http://Apache server address. If "It works" is displayed, it means that Apache is working properly.

Start when setting up the Apache system boot:

# install ncurses

Ncurses provides a character terminal processing library, including panels and menus. It provides a set of functions that control the cursor, create windows, change the background color of the foreground, and handle mouse operations. Enables users to bypass those annoying underlying mechanisms when writing applications under character terminals. In short, it is a function library that enables applications to directly control the display of the terminal screen.

1. Yum-y install ncurses-devel

Note: if an error is reported and the package cannot be found, the * wildcard is not recognized. Put double quotation marks "ncurses*" on the file name.

2. Source code compilation:

Make install

* error will be reported when compiling MySQL without installing ncurses

*-- without-ada parameter is set not to compile to ada binding, ada cannot be used to enter chroot environment;-- enable-overwrite parameter installs header files to / tools/include instead of / tools/include/ncurses directory for definition

*-- with-shared generates shared libraries

# install cmake and bison

After mysql 5.5, the. / configure tool is no longer used for compilation and installation. Instead of the. / configure tool, the cmake tool is used. The specific use of cmake is described in the document cmake.

# compile and install memcache

Memcache is a high-performance distributed in-memory object caching system. By maintaining a unified huge hash table in memory, it can be used to store data in various formats, including images, videos, files and database retrieval results. To put it simply, the data is called into memory and then read from memory, thus greatly improving the reading speed.
