CentOS LAMP配置记录

今天用yum方法搭建起了个LAMP环境，中间遇到了很多问题，经过google和各位前辈的帮助，终于将环境搭建起来，现在把完整的步骤记录下来：

一、换源，sohu的相当好用。

备份CentOS-Base.repo

cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

替换源

用vi打开CentOS-Base.repo，并将内容清空，然后将下面的内容复制进去，并保存。

# CentOS-Base.repo

#

# This file uses a new mirrorlist system developed by Lance Davis for CentOS.

# The mirror system uses the connecting IP address of the client and the

# update status of each mirror to pick mirrors that are updated to and

# geographically close to the client.  You should use this for CentOS updates

# unless you are manually picking other mirrors.

[base]

name=CentOS-$releasever - Base

baseurl=http://mirrors.sohu.com/centos/$releasever/os/$basearch/

gpgcheck=1

gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5

#released updates

[updates]

name=CentOS-$releasever - Updates

baseurl=http://mirrors.sohu.com/centos/$releasever/updates/$basearch/

gpgcheck=1

gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5

#packages used/produced in the build but not released

[addons]

name=CentOS-$releasever - Addons

baseurl=http://mirrors.sohu.com/centos/$releasever/addons/$basearch/

gpgcheck=1

gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5

#additional packages that may be useful

[extras]

name=CentOS-$releasever - Extras

baseurl=http://mirrors.sohu.com/centos/$releasever/extras/$basearch/

gpgcheck=1

gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5

#additional packages that extend functionality of existing packages

[centosplus]

name=CentOS-$releasever - Plus

baseurl=http://mirrors.sohu.com/centos/$releasever/centosplus/$basearch/

gpgcheck=1

enabled=0

gpgkey=http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5

二、更新一下系统

#yum -y update

三、安装Apache

#yum install httpd

安装完成后，用

/etc/init.d/httpd start

启动apache

设为开机启动

#chkconfig httpd on

四、安装MYSQL

#yum install mysql mysql-server

同样，完成后，用

/etc/init.d/mysqld start

启动mysql

设置MYSQL密码

#/usr/bin/mysqladmin -u root -h localhost password '新密码'

#mysql -u root –p     #进入MYSQL，

#Enter Password: <your new password>#             [输入密码即可]

更新MYSQL密码

    mysql> USE mysql;

    mysql> UPDATE user SET Password=PASSWORD('newpassword') WHERE user='root';

    mysql> FLUSH PRIVILEGES;

允许远程登录

mysql>GRANT ALL PRIVILEGES ON *.* TO 'username'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;

完成后就能用mysql-front远程管理mysql了。

让MYSQL数据库更安全

mysql -u root -p [此时会要求你输入刚刚设置的密码，输入后回车即可

mysql> DROP DATABASE test;                                               　　　　[删除test数据库]

mysql> DELETE FROM mysql.user WHERE user =’’;             　　　　　　[删除匿名帐户]

mysql> FLUSH PRIVILEGES;                                                   　　　　[重载权限]

mysql> exit;                   　　　　　　　　　　　　　　　　　　　　　　　　　　  [退出MYSQL]

设为开机启动

#chkconfig mysqld on

五、安装PHP

#yum install php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml libmcrypt

#/etc/init.d/httpd start            [运行HTTPD]

六、测试一下

在/var/www/html/新建个test.php文件，将以下内容写入，然后保存。

<?php

phpinfo();

?>

然后在客户端浏览器里打开http://IP/test.php，若能成功显示，则表示安装成功。       

至此，安装完毕。感慨，YUM真是太好用了。
