CentOS 5.5源码包安装LAMP环境

1.卸载旧的lamp环境

命令:rpm -qa | grep httpd

说明:查看是否安装了httpd软件包

命令:netstat -tnl

说明:查看现在端口的状态,主要关注80端口(apache) 3306端口(mysql)

命令:rpm -e httpd-manual-2.2.3-43.el5.CentOS --nodeps

命令:rpm -e httpd-2.2.3-43.el5.centos --nodeps

命令:rpm -e system-config-httpd-1.3.3.3-1.el5 --nodeps

说明:卸载软件包, --nodeps 如果有连带关系,也强制卸载

命令:cd /etc/httpd/

命令:rm -rf *

说明:到原来的apache安装目录下,将其所有的安装目录和文件都删掉

命令:rpm -qa | grep mysql

命令:rpm -e mysql-5.0.77-4.el5_4.2 --nodeps

说明:卸载mysql

命令: rpm -qa | grep php

命令: rpm -e php-common-5.1.6-27.el5 --nodeps

命令: rpm -e php-ldap-5.1.6-27.el5 --nodeps

命令: rpm -e php-cli-5.1.6-27.el5 --nodeps

命令: rpm -e php-5.1.6-27.el5 --nodeps

说明:卸载PHP

2.安装LAMP

(1).安装libxml2

cd libxml2-2.6.30/

./configure --prefix=/usr/local/libxml2

make

make install

(2).安装libmcrypt

cd libmcrypt-2.5.8/

./configure --prefix=/usr/local/libmcrypt

make && make install

(3).安装zlib

cd zlib-1.2.3/

./configure --prefix=/usr/local/zlib

make && make install

(4)安装libpng

cd libpng-1.2.31/

./configure --prefix=/usr/local/libpng

make && make install

(5)安装jpeg6

这个软件包安装有些特殊,其它软件包安装时如果目录不存在,

会自动创建,但这个软件包安装时需要手动创建

mkdir /usr/local/jpeg6

mkdir /usr/local/jpeg6/bin

mkdir /usr/local/jpeg6/lib

mkdir /usr/local/jpeg6/include

mkdir -p /usr/local/jpeg6/man/man1

cd jpeg-6b/

./configure --prefix=/usr/local/jpeg6/ --enable-shared --enable-static

make && make install

(6)安装freetype

cd freetype-2.3.5/

./configure --prefix=/usr/local/freetype

make && make install

(7)安装autoconf

cd autoconf-2.61/

./configure   //安装到系统库即可

make

make insatll

(8)安装GD库

cd gd-2.0.35/

./configure --prefix=/usr/local/gd2 --with-zlib=/usr/local/zlib/ --with-jpeg=/usr/local/jpeg6/ --with-png=/usr/local/libpng/ --with-freetype=/usr/local/freetype/

make

make install

(9)安装apache

cd httpd-2.2.17/

./configure --prefix=/usr/local/apache2 --sysconfdir=/etc/httpd --with-z=/usr/local/zlib --with-included-apr --enable-so --enable-deflate=shared --enable-expires=shared --enable-rewrite=shared --enable-static-support

make && make install

设置:apache(/etc/httpd/httpd.conf)

a.将LoadModule deflate_module modules/mod_deflate.so 注释掉

启动apache:  /usr/local/apache2/bin/apachectl start

重启apache:  /usr/local/apache2/bin/apachectl restart

停止apache:  /usr/local/apache2/bin/apachectl stop

查看80端口是否开启

netstat -tnl|grep 80

(10)安装MySql

A.安装

groupadd mysql

useradd -g mysql mysql

./configure --prefix=/usr/local/mysql --with-extra-charsets=all

make && make install   

B.配置

//创建mysql配置文件

cp support-files/my-medium.cnf /etc/my.cnf

//用mysql用户创建授权表,创建成功后,会在/usr/local/mysql目录下生成一个var目录

 cd /usr/local/mysql/

./bin/mysql_install_db --user=mysql

//将文件的所有属性改为root用户

chown -R root .

 //将数据目录的所有属性改为mysql用户

chown -R mysql var

//将组属性改为mysql组

chgrp -R mysql . 

C.开启mysql

/usr/local/mysql/bin/mysqld_safe --user=mysql &    

说明:‘&’表示在后台运行

//查看3306是否开启

netstat -tnl

//查看mysql版本信息

/usr/local/mysql/bin/mysqladmin version

//查看所有mysql参数

bin/mysqladmin variables      

D.安全性

进入mysql 此时密码为空

/usr/local/mysql/bin/mysql -uroot

查看mysql 用户权限信息

msql>select * from mysql.user \G

删除非localhost的主机

DELETE FROM mysql.user WHERE Host!='localhost' AND User='';

刷新授权表

FLUSH PRIVILEGES;

为root用户添加密码

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('root');

E.开启root用户的远程访问(如果是本地开发的话)

mysql>GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "root";

mysql>flush privileges;

'%'表示任何主机都可以访问,最后面的‘root’为密码

F.关闭MySQL数据库

bin/mysqladmin -u root –p shutdown(如果有密码则-p 没有不需要写)
